Problems with 2005 Jeep Grand Cherokee ELECTRICAL SYSTEM

After filling the gas tank of my 2005 jeep grand cherokee 5.7 liter hemi i accelerated onto the interstate and the car began to decelerate and all the information lights came on and began to flicker on and off as well as the headlights. vehicle then proceeded to drive normally with check engine light on but not pulsating. dealer next day could not look at it as i did not have an appointment. after several stops and turning engine off the check engine light went out. several days late the information gauge lights flashed and received a code message to service electric brake system. then they recycled and has been clear since. *nm

Dt*: the contact stated while changing the gear from drive to reverse there was a clicking noise. this occurred intermittently. while attempting to apply pressure to the accelerator pedal the engine made a roaring noise and the vehicle failed to pick up speed. the dealership rebuilt the transmission, however no other repairs have been made. the manufacturer has been alerted. updated 6/27/2006 - the vehicle battery would not hold a charge. the headliner had to be replaced because it was unraveling.. the sunroof motor had to be replaced. the transmission was rebuilt on 2-27-06 with on 90000 miles. the memory seat did not move back at times when the key was removed from the ignition. the tire pressure monitoring system was inoperative. the power steering pump was binding and had to be replaced. the air bag light illuminated on the dash. the rear windshield wipers were not flush with the windshield. *nm

Dt*: the contact stated while driving 35 mph through an intersection on normal road conditions, the engine stalled and could not be restarted. there were no warning lights prior to the incident. the vehicle was towed to the dealership, who diagnosed a fuel pump and fuel injection pump failure, both were replaced. after this incident, the vehicle presented transmission problems. the contact noticed a loss of power while driving 65 mph on a highway. intermittently, the transmission made noise when shifted to second gear. the vehicle had been taken to the dealership 20 times, however no error codes identified the defect. in one of the incidents, the yellow malfunction light illuminated and the dealership identified the defect as the computer control module and the driver shaft, both were replaced, however the transmission problem persisted. the dealership determined the vehicle could not be repaired. the manufacturer was contacted who recommended to take the vehicle to a different dealership. *ak the vehicle was not downshifting when going up hills and it would get stuck in second or third gear. the a/c and blower motor were inoperative, the dealer could not duplicate the consumers concern. the key became stuck in the ignition. all the dashboard lights were flashing, the cd player was broke. the brakes and rotors vibrated. the starter was replaced. the driveshaft and heater were replaced. the seats would not move back. the seat belts did not retract as they should. updated 01/17/07. *jb updated

While driving, all of the gauges will suddenly turn-off (including gas gauge, speedometer, odometer, temperature, and tachometer.) when this happens, the turn signals also stop working, as well as the headlights and dashboard lights. this has happened multiple times, and one time while driving at night. the car has been in the shop five times for the above stated problems (currently still in the shop). supposedly on the fourth visit, the dealership replaced the "cluster panel." however, this obviously did not resolve the problem as within two hours after picking up the problems happened again. *jb

I am the owner of a 2005 jeep grand cherokee laredo. on more than 10 occasions since i have purchased the vehicle i have inadvertently shut of the engine by hitting the key with my knee while driving at highway speeds. i believe this is due to the placement of the ignition directly above the driver's knee. to date i have been able to maintain control of the vehicle and get it restarted before an accident occurred. however, without power steering if i had been on a curve i doubt i would have been able to maintain control of the vehicle. i have been in touch with daimler chrysler via email in an attempt to resolve this situation to no avail. this may be unique to me but i consider it to be a serious safety condition that needs to be rectified. i have asked them to allow me to terminate my lease without success. at this point there is no alternative but to ask that an investigation be initiated to determine whether my concern is an individual problem or a serious safety defect. thank you for you prompt attention to this matter. *nm

Was driving on interstate 70 mph, light lit up, i couldn't accelerate, my car immediately slowed down, i barely managed to coast over to the side of road while dodging traffic. immediately put the car in park, shut the car off, turned car back on, put into drive, wouldn't budge. made the noise as if i was in neutral while pressing on accelerator. i shut the car off, pulled out the manual, read i could experience loss of power, not to drive the car, report immediately to be repaired. i called the 24 towing number, had the jeep towed to the dealership. when i received call from the dealership on april 10, i was told this issue was related to the recall problem that i had repaired in february. after further conversation on tuesday with the service department at the dealership i was given explanation that when i brought the vehicle in for the recall in february 2006, there was already damage done to the vehicle, they had to flush the engine. the power outage i experienced on the interstate was related to the recall, and in addition, they had to flush my engine again and replace a valve in the transmission. when i expressed that i wasn't comfortable driving the vehicle which such safety issues, the service man also agreed it was a safety factor. i was on the phone with chrysler yesterday, and was told that once this problem occurs a 3rd time, i can then go to arbitration, and take the next step, but that step wasn't clear. after expressing my desire to get out of my lease because of the safety concerns, i was told they couldn't do that. the 2005 jeep grand cherokee laredo is my 3rd jeep i have driven, no prior vehicle has had problems. at this point, i am supposed to go and pick up my vehicle even though i am not comfortable driving it, in the hopes the next time my power shuts down, i am alive to tell about it. and when that day comes, chrysler can then take the next step in pursuing further action. *nm

Dt*: the contact stated in april 2006, the vehicle accelerated on its own nearly causing an accident. the service dealer determined the computer system that runs the transmission was the problem. the computer issue allowed the transmission to leak improperly. also, in october 2006 the vehicle stalled at 30 mph due to all the electric in the vehicle failing.

Dt*: the contact stated while driving at various speeds the vehicle surged forward without warning. the rpms increased very rapidly. upon inspection the dealership determined there was a problem with the electrical system and the transmission. the dealer replaced multiple parts in an attempt to remedy the problem however, the surging problem continued. *ak

Dt*: the contact stated while driving or in park the vehicle was turned off when the contact's knee touched the key. even when the seat was moved farther back the problem still occurred. the key contains the remote keypad on it, which makes the key larger and easy to be hit. the ignition is located on the dashboard. the dealership replaced the ignition cylinder in an attempt to prevent the problem from occurring without success. updated 03/22/06

Tl* the contact owns a 2005 jeep grand cherokee. the contact stated that the vehicle failed to start. the vehicle was not diagnosed or repaired. the vehicle was included in nhtsa campaign number: 14v438000 (electrical system). however, the part needed to do the repair was unavailable. the manufacturer was made aware of the failure. the approximate failure mileage was 12,000.

Dt*: the contact stated while depressing the brake pedal at any speed the vehicle continued to move forward and the brake pedal went to the floor before the vehicle stopped. the dealer was able to duplicate the problem, but could not determined what remedy to use. also, the dashboard lights illuminated dim and bright. the dashboard lights were replaced twice in an attempt to solve the problem . however, had no success. updated 05/30/06. *jb

We leased a 2005 jeep cherokee in january 2005 and in january 2006 everything on the dashboard started to cut off including turn signals, odometer... and everything on the dash including the cd player, the buttons for the heater/ac would overheat and the car began to smoke for no apparent reason. we took it in to galeana, the local dealership and they could not find a problem, which apparently seems to happen quite often with chyrsler automobiles. shortly after the car began to break down everywhere. if i parked the car at a store, work, home... and went back to start it, it would not crank. this happens 8 out of 10 times and the vehicle has been taken to the dealership 5 times and they could not "duplicate" a problem and now they tell me they can't do anything for me. shortly after that at the end of 2006, as i was driving down the highway a "pebble" as the dealership calls it, went through my grill and hit the transmission coolant, spraying transmission fluid everywhere almost catching on fire with me and my two small children in it. we took it to the dealership and apparently the transmission was blown out, $4,000 dollars to replace. all of our other problems still exists and chrysler does not want to fix the problems or let us out of the lease. i have tried talking to chrysler and getting this issue resolved only to hear them telling me that this was not their problem. this is becoming a trend in their business and if they cannot fix the vehicles they manufactured they should not be making the vehicles in the first place. *jb

Dt*: the contact stated there was nhtsa recall campaign 05v396000 regarding the automatic transmission. the recall was performed on the vehicle, but afterwards it continued to shudder while driving. although the repairs were performed accordingly the vehicle had a strong shudder that could physically be felt by the contact as well as a loud chatter from the transmission. while shifting from park to reverse there was a loud clanking noise. aside from the problem with the automatic transmission the electrical system displayed some abnormalities. while driving the dashboard panel lights illuminated and all of the gauges, such as the fuel and speedometer failed to register. the defroster which was in use at that time stopped working. this problem lasted only a matter of seconds but returned to normal when the check engine light illuminated. this occurred 5 or 6 times in a 5 mile radius and abruptly stopped with no further incident. when the contact returned the vehicle to the dealer for the automatic transmission, the electrical system problem was reported to the service department. the contact left the vehicle at the dealer for inspection. however, the service department has been unable to duplicate the problem. *ak

Grand cherokee shut off by itself (lost power steering and brakes). car started right back up. this happened on a major highway around a sharp curve and could have resulted in a car accident with injuries or even death. brought the car to a dealer and they said they could not replicate the problem and sometimes the internal computer needs to be rebooted. i bought the car because of all the safety features. i will probably trade this car in. it's not worth my well-being. *nm

I am writing to correct the details of my complaint posted on your web site. i spoke with someone on the phone yesterday and the entry posted is inaccurate. my husband was driving my 3 month old 2005 jeep grand cherokee on october 24th (not the 17th) when the engine stalled without warning. he was driving in the left lane of a busy highway during rush hour in the rain. he was able to restart the vehicle after reaching the shoulder of the road. he then stopped at a service station but they could not diagnose the problem. i called the service department at the dealership and was told to tell my husband to drive with the defrost on to keep the engine idle up. i then made a service appointment and asked to have the oil changed at the same time. they kept the truck overnight and said that the diagnostic tests did not reveal any problem and they were unable to duplicate the incident. i was also told that they discovered a "milky" substance when changing the oil and put in a new filter. they did not say that this was the problem. they told me that if it happened again, i should bring it back. my issue is that waiting for a vehicle to stall at high speed on a busy highway is a real safety concern. my husband and i are reluctant to drive the vehicle and actually rented a car to visit our son who is almost 250 miles away at college. i hope you will correct the entry as it is important for other owners who are experiencing the same problem to have the actual facts.*jb

dt: the contact's husband was driving and the vehicle stalled without any warning. the service dealer could not find the cause of the problem when performing the diagnostic test, and they could not duplicate the problem. the service dealer said there was a milky substance mixed with the oil. this could have caused the problem. therefore, they changed the oil and filter. the contact believed this may have been an electrical problem. *ak

It all started with the seats not staying in there settings(driver 1 driver 2. then the auto dimming rear mirrors would go dark at any time. the rain sensor wipers stopped working. the car would accelerate on it own. even when in park, then the seats started moving to driver 1 then 2 as i was driving it. the jeep also has a bad odor in it. it is at the dealer as i speak, the jeep is not safe to drive. fog light go on and off at any time as i was driving the jeep to the dealer the jeep started the speed up on it own the car hit 68 mph in a 45 mph zone , so as you would thing a state trooper pull me over, he ask me why it took me so long to pull over, so i told him the problems with the car, will the look he gave me ! then right in front of him as the car was in park the instrument panel lit up like a xmas tree and the car started to accelerate all by it self, will i did not get a ticket and he follow me to the dealer. *nm

My knee hit the ignition switch while i was driving, which turned the vehicle "off" at 65mph on the highway. the brakes and the steering lost power. this is happened about 10 times overall. thankfully, i have always been able to turn the car back on before any accidents happened. *tr

This 2005 jeep cherokee was purchased brand new from gary barbara jeep / chrysler, upon driving the vehicle the dash lights, gauges, a/c (happens with heat as well) began going on and off then off while vehicle is still in motion, this happens at any speed including no turn signals or brake lights. this sometimes will regain normal operation but most times the vehicle has to be pulled over and shut off then restarted. the vehicle was taken into the purchased dealership and issue was not resolved "saying could not find anything wrong" then as this has continued to happen was taken to multiple dealerships with same issue and same response. this went on the whole time the vehicle was under warranty, and the issue was never resolved. i continued to contact chrysler over the years and no one would respond, at one point a chrysler representative told me to go pound sand since the vehicle was no longer under warranty after me calling to follow-up on another (one of many) detailed letter regarding this issue. this continues to happen and obviously the vehicle is not safe, i refuse to resell the auto and want it fixed. i recently received a recall notice this year - 2015 for the ignition switch, i am not implying this is the repair fix for the issue but re-opened my quest to get chrysler to properly repair this issue. i was told by both cherry hill jeep/chrysler and chrysler direct case #[xxx] the parts for this recall are unavailable, a date or time frame for them is unknown and if i wanted would have to pay a $98.00 fee to get the auto diagnosed to address the issue of the powerloss during operation of auto. this has continued my belief that chrysler really does not care about its customers or its products nor the safety of their automobiles. respectfully, [xxx] [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).' *jb

I leased a 2005 grand cherokee lardo (v8) on june 30, 2005. during the first 1.5 months the vehicle has stalled out loosing complete power on 5 seperate occasions. june 24th - pulling out of my driveway june 26th - backing out of my driveway august 20th - pulling out of my driveway august 21st - while traveling 70mph on the expressway (us-23) while traveling 50mph on us-24 when the vehicle stalls it would loose complete power (dash board lights, radio, and yes power steering). after the two expressway incidents i immediately took it back to the dealership where after looking at it they told me they were aware of this problem, but did not know what was causing it or how to fix it so i could pick up the vehicle that afternoon. they also told me they had a few of their own mechanics experience this same problem, but it just went away. i ended up going through several different managers before speakign with the dealership general manager. the following day (the second day they had the vehicle in the garage they told me they gave me wrong information and this has hever happened before....they were aware of 2004 grand cherokees having a starting problem not a stalling out while driving problem. they said they would not give me a new vehicle or terminate my lease when i requested it since i feel this car is unsafe for my wife to drive with my child. they have now sent it home with a mechanic so he can drive it back and forth to work to see if it happens again. they have not repaired or replaced any parts.

I leased a 2005 jeep cherokee in june of 05. while traveling on i-69 to indianapolis in august of 05 my jeep shut off for no apparent reason. i called the dealership and told them of the situation. they told me if it happened again to let them know. everything was fine until june of 06 when we were again travel on i-69 and the vehicle shut off again. i called the dealership again and they took the vehicle in for service but could find nothing wrong with it. we got the vehicle back and three weeks later my husband was driving alone on i-69 and the vehicle again shut off almost causing an accident. i called the dealership and they have had it for about three weeks with various people driving it with an auto-pilot hooked up to it, but nothing has happened. so i now have a vehicle that i do not feel safe driving with my 16 month old in the car for fear that it will just shut off and cause an accident. something needs to be done about this problem before someone gets seriously hurt.*jb

Transmission: i have a 05 jeep cherokee that has continuously had a transmission shudder problem. while driving, the transmission shudders, feels sluggish, jerking the vehicle forward and backward. it happens while traveling at various speeds, but it is excessive while at the 40 mph & 1500 rpm range. the first time it was taken to the dealership, they did a transmission flush and told me to pick it up. the second time, they ordered, then later replaced the drive line. the third time to dealership, the service technician said they reprogrammed the transmission. it has now been dropped off for the same problem 4 times, and still no remedy. i called the dealership again and told them about a possible recall i read about on the nhtsa website on the problem i was having. the public information specifically suggests a remedy, replace the torque converter (which has not been tried on my vehicle). i asked them why they couldn't use that information to fix my vehicle since it is still under warranty rather than wait to see if a recall is even issued, and i was told that the engineers are working on a remedy for the possible recall i was reading about, and it may not affect my vehicle. so, until that recall is issued, nothing can be done. air conditioner:on 9/22/05, while vehicle in motion, air conditioner, radio, &all dash lights went off at same time, stayed off for 5 seconds or so, then came back on. 5 miles or so later, the same thing happened again. later on the same day, the air conditioner would only work on the highest setting. on my way to the service appointment the next day, the air conditioner would come on and turn off itself, like it has an electrical short in it or the dash. i can also smell plastic burning/melting but can not locate where it is coming from. dealership now states that parts are not available to fix the air conditioner, and they do not have any timeline for parts availability. no clue why the dash lights shut down. *jb

2005 jeep grand cherokee - 07/26/2005 - vehicle did not start, dealer replaced battery. 06/10/2006 - stalled while at light, dealer attempted repair by tightening connection in junction box. 06/28/2006 - vehicle stalled while driving, dealer could not duplicate no repairs attempted. 07/07/2006 - vehicle stalled while on interstate, dealer replaced forward control module. 07/26/2006 - vehicle would not start - dealer could not duplicate no repairs attempted. 09/01/2006 - vehicle stalled while driving - dealer duplicated problem - dealer replaced battery. 09/15/2006 - vehicle stalled while driving, has been in dealer possession now for 7 days - cannot duplicate - no repairs attempted. vehicle has been out of service for same problem for a total of 39 days and counting. situation is a danger as the vehicle will just die while moving and driver cannot get it off road. vehicle only has 20,000 miles and has had problem since 155 miles. daimler chrysler's response is unacceptable - vehicle is a safety hazard and an accident waiting to happen. when is enough - enough? loss of life? maybe then someone will realize there is a problem with several of these 05 jeep grand cherokees with same problem! contact me [email protected]. *nm

Dt: the car was a rental car. the driver rented it last week. the contact was driving on interstate in the right lane and driver's knee hit the key and the car shut off. the driver lost power steering, and had to come to a stop in the middle of the highway. the driver had the same problem again on an off ramp. the car shut off and he lost power steering, had to coast to a stop again. the local chyrsler dealership advised that there was a government mandate that requires that the key be located on the dashboard. the owner contacted rental company upon return, and made a complaint. the driver wanted others to know. the vin number not listed because the contact was not the owner, this was a rental car. *ak

'05 gc ltd 5.7 l information light (service four wheed drive system) flashes on contiunally in the information menu. dealer kept 2 days and says they have to get a sensor, dealer says chrysler does not know how to fix.

Dt: consumer owned a 2005, jeep , grand cherokee laredo. the air condition had a part that needed to be replaced on 7-18-05. and later on 7-20-05 the blower fan and heater would only work on the highest setting. a part melted, and there were too many amps being driven to the resister. they had to the replace blower motor, relay, resister, and a wire harness. *ak

I have a 2005 jeep grand cherokee. several times since i bought it in march the engine has suddenly stopped while i was driving. when i stop the car and put it in neutral, the engine will immediately restart. the dealer has not been able to find why this is happening. this is far more than a nuisance. should it happen, for example, while i'm passing another car, it could result in a crash. i have talked to jeep about this and they claim this condition is impossible. however, the dealer told me that his regional manager has experience the same problem with his 2005 jeep. however i have discovered the source of the problem. the key and ignition switch have been mounted on the steering column. should the driver inadvertently bump the key with his/her leg, you can stop the car. i have confirmed this condition and reported it to the dealer. he mentioned that the regional manager also suspected this was the case. i am a normal sized male, 165 pounds, 5' 11". it should not be possible to stop the car in the manner i am describing. it has happened to me several times since i took delivery of the vehicle. i believe this is a condition that is dangerous and needs to be pursued by daimler chrysler asap. registered professional engineer,

Vehicle transmission has always made strange clunking noises. vehicle began to drop out of gear while driving and then finally (and currently) will completely shut off while driving. this has happened on numerous occasions and dealership says that they cannot duplicate the problem. a customer service manager did tell me that jeep is aware of the problem and this is a common problem among v8 models such as mine but that they just do not know how to fix it so they have not yet issued a recall. however, jeep is putting so many people at risk of an accident. not only the vehicle drive but everyone else on the road around the vehicle. the vehicle now shuts off while in motion driving on a fairly regular basis but with no consistent pattern. $34,000 dollars worth of worry. *jb

While driving on a busy streetwith my 2 children in the car, i had to stop @ a red light and when the light turned green, i proceeded to go but couldn't and realized that the car had shut off. i tried to restart the car in a hurry due to oncoming traffic but was unable to. finally i find the hazard lights and put them on to let people know that my vehicle was stalled. i had to take the key completeley out and put it back in to restart the vehicle. i could've had an accident. took the car in and left it there for 3 days and the dealership stated that there was nothing wrong with my car and to take it home. so i did. i went out of town that weekend and the same thing happened with the exception of the vehicle was actually in motion when it shut off for the second time on a another busy street. i quickly turned on the hazard lights and once again had to restart the vehicle. as i was making my way back into to town, the check engine light came on and i took the car back to the dealership for another 3 days all for them to say that they reprogrammed the transmission and engine computers and that should resolve the problem. but it didn't... it shut off again about a week later right after i dropped my kids off at school. this is ridiculous and is a safety hazard. i took it back again, keep in mind this is the third time...this time they changed out the ignition cylinder after 4 days. i have only had it back now for 4 days and once again the car shut off at a light on a busy street. so the people at the dealership will be seeing me again!!! this is dangerous and very inconvienent for me and my family.

I have a 2005 grand cherokee laredo under 3000 miles. my engine light has come on less than 10 times ,and my car has stalled when come to stop light or complete stop about 5 times. i have made 5 trips to the dealer and the first few times they could not find anything wrong with it. then they determined it was related to the remote start which they had installed. i got it back and they said it was fixed and it stalled out when i pulled into my driveway that very day. engine light came on again exactly 1 week later. engine light is still on now. this will be my 7th trip to the dealer for this problem. i would also like to say that i have also hit the key in the ignition twice which made the car shut off and my car has also revved up with the brake on just as the other complaints on this site. i am also only getting 12 miles per gallon!*ak

Same as 101001116 and 10106060. my husband was driving on rte. 75 at aproximately 75 mph when his knee bumped the key in the ignition switch and car turned off. very scary, fortunately around 8pm and not as much traffic as usual. could have been very bad if traffic had been a bit different.*ak

Tl* the contact owns a 2005 jeep grand cherokee. the contact stated that the electrical components in the vehicle failed. in addition, the transmission gears slipped. the failure occurred on several occasions. the vehicle was not diagnosed or repaired. the manufacturer was notified of the failure. the approximate failure mileage was 30. updated 8/10/15*cn

While driving on the freeway 70 mph and when slowing down to take an exit the vehicle shut down, there was no power at all. consumer was able to pull over and restart the vehicle. consumer drove the next day to the dealership and left the vehicle. dealer could find nothing wrong after three days. after picking the vehicle up from the dealer it shut down while at a stop light. consumer took it back to the dealer. no defects could be found. consumer went on a trip, and the vehicle stopped while making a right turn. again the dealer could not find any defects. *ak computer was replaced. there was also rear suspension noise. sunroof is noisy. *tt

Consumer contacted the dealer about an ignition problem. mechanic stated that a cause could not be determined. consumer informed the mechanic. when driver entered into the vehicle and started it up, and while driving driver's knees hit against the ignition. this caused the vehicle to shut down intermittently, but driver was able to restart it. *ak

Driver's knee would hit the ignition switch while driving,this caused the vehicle to shut off. contacted the dealer for this problem. dealer informed consumer no complaint on this problem was recorded. *ak

Bought a 2005 jeep grand cherokee in late october. have had numerous instances on engine shutting down while driving, including on a busy expressway. neither chrysler nor the dealer was able to correct the problem (the dealer's service department was in contact with chrysler techical support when trying to repair). they tried a couple of repairs suggested by chrysler that did not resolve the problem. finally realized i was gently bumping the ignitiion key or attached keys when going from the accelerator to the brake and the switch was moving to "accessory" from "on" and killing the engine. the two positions are very close together. have talked to two people at the dealership who have had this happen with either a jeep or pacifica. to me this is a serious safety concern that could get someone injured or killed if in traffic. i removed all other keys and even the ring from the ignition key to try to prevent this from happening. with this information, the dealer has agreed to replace the ignitiion cylinder; i asked that they check the other grand cherokees to see if it's a common problem several days ago, but they have not yet responded. to me as an engineer, there are two problems: the ignition switch is very low on the dashboard where the key can easily be hit, and the two positions on the switch are very close together, making this problem easy to occur. if there is the slightest weakness in the spring in the ignition, this is even more likely.*ak
