Problems with 2005 Ford Mustang ELECTRICAL SYSTEM

Failure of instrument cluster and water leak in passenger side foot well. speedometer non-functioning, fuel indicator non-functioning, and engine temperature gauge non-functioning. provides serious safety hazard without knowing vehicle speed. any substantial rain results in water pooling in passenger side foot area, and saturation of fuse box area, which provides concerns for a vehicle-wide loss of electrical power and brake/steering control. i have looked at several online owners' forums and there are numerous cases of this commonly-documented safety problem, but ford motor company refuses to address it until nhtsa issues a recall. i have called fmc, and they refused to address the issue. *tr

2005 ford mustang instrument cluster fails. it will either not work or is improperly reporting speed, temperature, battery, tachometer, and gas supply. *tr

Was driving the car and the gas gauge started acting weird. stopped and filled up the car and after starting the car the gauge went all the way past 'e'. shortly after that the speedometer started sticking. i could be at a stop light and it would show i was going 20 mph. usually turning the car off and back on would get the speedometer to go down. the higher the speed said the more you had to turn it off and on since it only went down a little at a time. now the gauge is stuck at 80 mph and doesn't move at all. the tachometer is also messing up now. it will vary from being too low to being too high to being just right. *tr

The first thing to happen around june of 2011 was my gas gauge dropped to empty and the low fuel light came on when in fact i had a full tank. this started doing it every so often and now does it on a daily occurrence. the next thing approx. a month later my tach started acting strange and is now stuck in one position and has been that way for about 6 months. starting last september the speedometer would drop down to 0 while driving, sometimes it shows going 20 or 25 miles per hour when in fact i am probably doing 55 or 60. this is very distressing as i love my mustang and bought it brand new in december 2004. it now has a little over 70000 miles and i am seeing where others have this same problem. this is not a fluke but sounds like a defect on these mustangs. it is not a cheap fix and ford needs to step up to the plate and a recall needs to be done. this is a safety hazard that needs to be repaired. *tr

Speedometer erratically displays wrong speed. when parked, the speedometer sometimes over 25 mph. while driving approximately 30 mph, the speedometer reads over 80 mph. *tr

Speedometer on my 2005 ford mustang does not work properly. it stuck and does not move. other owners of 05 mustang v6 have this same problem as well as malfunctions with other gauges. it is a huge safety issue when gauges don't work properly. this is not an isolated malfunction, as it is problematic in so many 05 mustangs. *tr

The incident reported below also happened to me. ford replaced the entire instrument cluster at no charge to me. i got in my car an started the engine. i then noticed my fuel gauge and speedometer were not working at all. i have always taken care of my mustang an i think ford should recall the cluster. there's been plenty of 2005 models with very same issue. please recall the gauge cluster it's the right thing to do for a big name company like ford. *tr

Cluster gauge on my 2005 mustang is reading 70mph at all times. even when the car is off. *tr

I was driving down the road at the speed limit when all of a sudden the engine light came on and the car immediately stalled. i had to pull over to the shoulder and put my hazards on so i didn't get hit from behind or cause a dangerous accident to the other motorists. i turned off the car, left the hazards on and waited a few minutes before starting it up again. it started thankfully and i was able to pull into a parking lot safely to avoid an accident. very frightening experience. eventually someone was able to come and help me get my car home. we believe that the incident had something to do with the defective throttle body, and throttle body sensor. ford should have recalled this problem and pay for their faulty parts. this car is a 2005 ford mustang convertible with a v6 engine. *tr

Failed speedometer. speedometer pegs past its upper end, and then resets every couple of days. *tr

My 2005 v6 mustang gauge cluster is erratic. rpm run high/low and stick. gas gauge has spun past full and points toward the floor. temp gauge sits at 3 o'clock most of the time. speedometer intermittently works fine, reads incorrectly or doesn't work at all. *tr

Gauges quit working. started with speedometer and has grown to include not only the speedometer but also the tachometer and temperature gauge. *tr

It had rained in the day, but was not raining at the time. turned the a/c on as the glasses were foggy. dashboard warning system went off with all kinds of warnings. all electrical components including lights, radio, locks failed while the car was being driven. the engine was running ok. drove home as it was during the day. found water in the fuel cutoff switch on drivers side and on the floor on passenger side near the fuse box. used paper towels to dry both. did not help. left the car for an hour or so and then it was working fine. could have been a major safety issue if it happened at night. car has been running fine since. *tr

2005 ford mustang - instrument cluster failure. the speedometer gauge shorted out, heat gauge improper reading, and tach stuck. concern of an electrical fire. in reading more information, many 2005 ford mustangs have this problem that can cost up to $800. ford should recall. *tr

My speedometer started acting erratic. it does not work at all now. the needle is stuck past 120 miles. now my oil, water & battery gauges do not work. asked my ford technician during my regular oil change and checkup about the problem and they stated that is was a sign my alternator was going out. i had my alternator changed, but it did not correct the problem and after that is when my other gauges quit working. since this is a problem with almost every one made during that year, you would believe that ford would not want to tarnish their name by not issuing a recall. i have always owned a ford, but my family has recently changed to different makes and i will definitely consider changing after this. this is a safety issue because if your gauges are not working, you could stall in traffic by running out of gas, overheating, engine lock up, etc. i need my car so i can make a living for my family and i do love my car, but i am considering getting rid of it because i am afraid something will happen while i am in traffic. this does not need to wait until people start having accidents or dying. with the economy the way it is today, most people cannot afford to get their car repaired or change cars so they are left with no choice but to take chances. if it was your family in the car and something happened in traffic, would a recall come any faster? i have noticed recalls in the news happening faster when someone dies, but i wonder how many complaints were received before that happened? i suppose it would happen faster if the news were to pick up the story of how many problems existed and were left unnoticed. thanks for looking into the problem, but please don't wait too long. *tr

The speedometer on the instrument cluster stopped working. a few months later the tachometer stopped working. in april 2013, the temperature gauge stopped working. all gauge needles are stuck on the bottom of the gauges. *tr

My 2005 ford mustang v6 has been having speedometer malfunctions weekly. these malfunctions cause the speedometer to start at numbers that are not 0, resulting in an inaccurate reading of my speed. it read 120 while i may only be going 40 and even when i shut down the vehicle it will remain at 40+. a temporary fix is to turn the vehicle on and off which sometimes causes the needles to slowly drop, but usually it will stay over 20 for extended periods of time, and when i do succeed in reaching 0 within a week or two the problem will occur again. i have been in contact with many other owners of the same model and year of this vehicle and all are having similar problems, most of us have gone to a ford dealership and have been told that it will be a $500-$650 repair/ replacement of the instrument cluster which seems to be the reason for the problems, but since so many are having a similar problem shouldn't this be a recall? *tr

Tl* the contact owns a 2005 ford mustang. while driving approximately 65-75 mph, speedometer displayed an abnormal reading of 20 mph. the vehicle was taken to the dealer where the dealer advised that the instrument cluster would need replacing. the vehicle was not repaired. he called the manufacturer and was advised that there was a national back order for the part needed to repair the instrument cluster. the vehicle was not repaired. the vin was not available. the approximate failure and current mileages were 48,000.

Tl* the contact owns a 2005 ford mustang. the contact was driving 25 mph when the speedometer malfunctioned. the contact called the manufacturer and the manufacturer took a complaint from the contact but did not provide any assistance regarding the instrument cluster. the dealer advised to bring the vehicle in for diagnostic testing. the vehicle was not repaired. the contact was concerned because he was not aware of what speed he was traveling and believed the manufacturer should be liable for the repairs due to the numerous complaints he discovered online in regards to the failure. the failure mileage was 75,000.

There is a manufacturer's defect that allows water leakage into the instrument panel/smart box junction and subsequently into the vehicle itself. resultant issues include the inability to drive the vehicle (frozen shift), electrical failure with loss of instruments including various gauges, brake lights, ventilation/ac, power windows, and headlights, and physical water damage (mold/mildew). ford is aware of the defect and later models were redesigned to compensate for the flaw. however, ford refuses to issue a recall or acknowledge the deficiency, nor will they provide any kind of financial assistance with the necessary repairs directly caused by this defect. should the mustang experience the above mentioned electrical failures while being driven, an accident could occur. there are numerous similar incidents reported about this exact same issue, and ford must be held accountable. i spoke to ford "customer service" on 5/5/11 to report the issue and request financial assistance for the repairs. i was told to take my vehicle to the dealership, pay for the diagnostic test, and have the dealership confirm the "defect". i made a follow-up call to ford "customer service" on 5/9/10 to report that the service manager did confirm the defect and that he had seen similar problems. however, ford said they were not responsible, would not provide financial assistance, and that i was "misinformed" by my initial call to ford in giving me hope they could somehow help me. additionally, they stated that i "should not expect my ford vehicle to last beyond 100k miles". in the meantime, we are responsible for the towing, diagnostic, and repair bills, so the ford service department is profiting from this. this was our fourth ford vehicle, and it will certainly be our last.

Instrument cluster on 2005 ford mustang v6 coupe. speedometer began to show incorrect speeds. sometimes it is 15-20 mph below actual speed and occasionally drops to zero or below. *tr

I own a 2005 ford mustang gt rain leaks into the passenger side interior above the fuse and smart junction box. when i was driving it in the rain i lost all electrical functions ie headlights,brake lights wipers, horn and so on. luckily i was driving during the day and could see had it been night time i would have crashed. i called my ford dealer and they stated that are aware of the water leaks with the mustangs but did not offer to fix for a defect on their fault. a search of the internet shows many people with the same problem. *tr

Speedometer and gauges not working correctly. *tr

Instrument cluster not working properly. works off and on. rpm stuck. speedometer stops working on long rides. *tr

I have an 05 mustang, automatic, v6 it has about 65,000 miles. i like everyone else am having problems with the gauges and the car stalling for no reason. i noticed no one has been killed yet so i guess that is what ford is waiting on before doing a recall. this is crazy. someone should make them take a look at what is happening with this vehicle and issue a recall.*tr

I was told that these items, the fuel gauge, tachometer parts of the instrument cluster are faulty in most 2005 mustangs. there have been so many problems that ford changed it for 2006 models. i was further informed that if enough owners complained that a recall would be activated. hopefully i'll be hearing from you and or ford motor company. thank you. *js

I've a ford mustang 2005 v6 [coup] with 66,000 miles on it. few months back, i was driving and suddenly realized that the speedometer gauge jumped to 120 mph even when the car is stationary. of late, my temperature gauge is also giving erratic readings.. this is a problem which seems to be inherent in the car itself since this has been reported in umpteenth internet forums particularly for ford mustang 2005 v6. would request you to consider a recall for this issue. thanks. *tr

2005 ford mustang coup v6 - instrument cluster failure - headlight failure -turn signal failure - false information via digital instrument display - door lock failure - radio failure. indications of failure began in january 2010 with speedometer failure. in the fall of 2010, the charging system gauge failed but in-car system check reported all was normal. during the summer, speedometer returned to normal operations. winter of 2010, speedometer failed again. end of january during warm weather, speedometer return to normal operation. february 1, speedometer fails again. february 2, ticking sound from behind the instrument cluster is noticed when ignition is turned off and speedometer fails. on february 4, 2011, entire instrument cluster failed, on board diagnostics reported traction control failure, low brake fluid, low oil pressure, parking brake on, low fuel warning, seatbelt warning, abs warning. at the same time, the power locks failed, power windows failed, security system failed, service light illuminated, interior lights failed, and radio failed, and windshield wiper fails. all these failures/incidents happen in cold weather only. *tr

The speedometer on my 2005 ford mustang is stuck at 0.

Speedometer and rpm would jump around then it just stopped working then my temp gauge went all the way past h and its stuck there. *tr

The speedometer began to malfunction on my mustang last winter. some days it would work fine, other days the needle would not move at all, and on other days it would read a speed that was below what i believe i was driving based on the other vehicles traveling around me and my experience driving my car. the speedometer was mostly fine over the summer, except on a couple of occasions where my speedometer was reading 10-15 mph under what i was driving (at least what i think i was driving based on other vehicles on the road). i am not sure what caused it, but i would stop on a long road trip and when i got in and restarted my car the speedometer would be reading incorrectly. now that the weather has turned cold again for fall my speedometer and now my tachometer have quit working properly. they speedometer hardly ever works correctly now. mostly, the speedometer needle doesn't move and when it does it is showing a speed below what i am driving. as for the tachometer, it now longer works correctly as it is currently pointing at 6:00 o'clock. the needle still moves, but it is not reading anything when its starting position is at 6:00 o'clock. *tr

The car's instrument cluster suddenly completely malfunctioned, the "fail-safe" engine system light came on, causing the engine to shut down and to suddenly stop the car in moving traffic. this was truly a life-endangering situation. the speedometer and the engine temperature dials of the instrument cluster had been erratic in the past weeks before the incident. obviously, this car is unsafe to drive. for more than five weeks ford motor company has claimed to have no instrument clusters available to fix the problem.

I was driving on the 407 traveling 110 km per hour. windows, radio, fan, lights, emergency lights started to fail. the car was losing speed. it broke down on the highway and emergency lights nothing would work. i called 911 because i was scared of getting hit. police came and my car was towed to the ford dealership. they replaced the alternator and battery costing 566.00. a month later the same thing happened. i find out that this is a common problem with ford vehicles, a faulty firewall seal causing water damage to the smart junction box. i found many ford consumers online with the same problem. this is a danger to our highways. ford is now telling me this will cost 3000.00 to fix, not only is their manufacturer's defect a danger, it is costing consumers thousands of dollars. they have lied to me saying it is caused by a crack in my window. they are trying to cover up a bad defect. *tr

The engine cluster for my 2005 mustang is malfunctioning. the rpm gauge is not operating properly. i was told by a ford dealer that this was a common malfunction. *tr

All gauges stopped working. first speedometer, than the tact, gas gauge, and finally the hot/cold gauge. i don't know how fast i'm going and i don't know how much gas i have in my car. every time i drive my car it's a guessing game between gas and speed. ford needs to issue a recall before someone gets hurt or even worse killed because of this. if not a recall at least make the part cheaper so we can get it fixed instead of going to some make shift shop to get it repaired. $440.00 plus a $300.00 core is way to much for a cluster. *tr

2005 ford mustang with parking brake problems which caused the vehicle to be damaged after rolling down a hill. consumer is also expressing discontent with the ford company. *kb the consumer stated the door handles were replaced three times, the convertible top had to be replaced, a new fuel pump was needed which was recalled, a new radio was installed, and the battery was replaced twice. *jb

Went to start my car and noticed the speedometer was sitting on 20mph. up to this point, it had no problems. i tried to reset according to manufacturer instructions with no success. a few days later it had moved up to 80mph. after a few more trips and several attempts to reset the speedometer, it finally dropped back down to 0. however, less than a month later, i have noticed it moving back up. up to this point i have not replaced any parts as it is unknown what part is not causing the issue. *tr

The speedometer, fuel gauge, rpm gauge and engine temperature gauge all no longer work in my 2005 mustang. they have all failed to function properly. *tr

While driving in the evening the engine temperature and fuel gauges failed. the temperature gauge gradually kept climbing higher above the red line. an inspection of the engine compartment reveled that the engine was operating at normal temperatures. the fuel gauge also started registering incorrect reading; gradually moving past the full line even though no fuel was added. starting and stopping the engine caused the fuel gauges and temperature gauges to turn clockwise (or higher). both gauges currently point down and are effectively useless. the repair shop in researching how to replace or repair the component and how much the part will cost. the failed components appear to be linked to the vehicle's speedometer. *tr

2005 mustang v6 automatic. stalling unexpectly this has happened several times. repair shop unable to find out what is wrong. also temperature gauge not working already replaced the sensor and it worked for a while now not working again. now my transmisstion is slipping. and of course filling the car with gas is also a problem. seems to be that all these problems are very commong and i think ford should be taking care of fixing them. *tr

Speedometer sticks at zero or any other speed. seems to be a random malfunction that may or may not be aggravated by weather conditions. *tr

All of my gauges are out..i don't know my speed, temp of my car, etc. dealership advising the cluster is out & its a common problem. estimate for repair is about $1200.00. i see multitudes of complaints for this same reason..same year & make & model. this obviously should be a recall. *tr

Tl* the contact owns a 2005 ford mustang. the contact stated that none of the gauges on the instrument panel were operable. the vehicle was taken to the dealer where the contact was advised that the instrument cluster needed replacement. in addition, the dealer advised that the stepper motor needed to be replaced. the vehicle was not repaired. the failure mileage was 60,000 and the current mileage 64,000.

Tl*the contact owns a 2005 ford mustang. the contact stated that the speedometer would indicate incorrect speeds. when the vehicle was traveling 55 mph, the speedometer would display a reading of 110 mph. the vehicle had not been inspected or repaired. the vin was unavailable. the current and failure mileages were approximately 78,000.

Entire gauge cluster is now inoperable. first thing to stop working was fuel gauge, needle stuck around 1/8th tank. low fuel lamp indicator still works and is only way to know when low on fuel. around same time speedometer needle started sticking at random points, more noticeable as weather got cooler. would go up with acceleration but not all the way back down when braking. needle is now stuck all the way cw on trip reset button. odometer still works correctly. then same with tachometer a few months later. finally quit looking at gauge cluster while driving, not really sure when coolant temperature gauge got stuck and quit working. have seen many complaints of the same problem. ford seemed to fix the problem in the next year model, but still refuse any sensible solution for affected vehicles in 2005. to have issue fixed by ford: $660 for new instrument cluster + labor. *tr

My 2005 v6 mustang gauge cluster is erratic. tach fluctuates between not working at all and reading 1000 rpm low. gas gauge has spun past full and points toward the floor. temp gauge same as gas gauge. speedometer intermittently works fine, reads incorrectly or doesn't work at all. *tr

Instrument cluster: the rpm and temp gauges do not work. first the rpm gauge stopped working and 1 year later the temp gauge started jumping around to cold and then hot. i have had to pull over to check the engine numerous times and the engine was not hot. now the temp gauge does not work at all and the gauge points downward as the rpm gauge. this is dangerous. i'm worried the engine may overheat and i will have no indication. i see there are many other 2005 mustang owners with the same problem. there should be a recall on this. *tr

Speedometer, tachometer, temp , and fuel gauges fail intermittently. gauges get stuck or provide false readings. *tr

On september 1, 2010, the gas gauge on the vehicle failed - reading more than full, and other various irregular readings. repaired for $75, then failed again next day. have not repaired again as dealer estimates cost at $1500 due to multiple failures according to their tests. gas light still works when fuel is very low. on november 1, 2010, the speedometer failed - reading 80 mph when vehicle is stopped. have not repaired, using gps to estimate speed. i contacted ford about these issues as they seem very common with this model & year vehicle by a quick search online. they advised that i should just get it fixed at the closest dealership. given the frequency of this failure i feel they should be responsible as the original parts must be faulty given the number of people posting the same issues online. ford advised that your agency was the only one that could order a recall. i would think that knowing how much gas you have or knowing how fast you are going are valid safety issues that ford should be required to fix at their expense.

Speedometer does not work accurately, either moves erratically, or not at all. *tr
