Problems with 2008 Chevrolet Impala ELECTRICAL SYSTEM

Rear door locks, defrost, trunk lid stopped working. noticed smoke on my passenger side while driving in town. i took it in and was shown that it melted the wires together and melted the rear body harness connector. ( i kept the part if needed) this is a danger to drivers. the fire can start at any time while driving! i believe this should be a recall. after researching i see this is happening to many of these cars.

Reduced engine power light comes on intermintently while driving had the throttle body and accelerator pedal replcaed twice after i bought the car with 75000 miles on it. still the reduced engine power light comes on. just yesterday i was unable to start my car. throttle problems light came on in window

My car stopped on 630. it said disabled full throttle. i had to sit for 15 minutes before it would start. i then hear a clicking noise that started at 830am and stopped at 832am. i've had nothing but problems with this car. do not buy any impala, unless you have a lifetime of fixable recalls. it's hot in arkansas and to stall for 15 minutes with children in the car is unacceptable. when you call chevy customer service, they can not help you with anything. they just take your vin number and state oh i don't see a recall for your vehicle, although you read 5598 problems/same issue you are having with your car. erratic transmission is the whole problem. so to chevrolet and company please think about families and children when attempting to sale a new car with used products. it's not cool and the sad part is you will not fix it. warrant my behind chevy need a lifetime of recalls for everyone on all cars. may jesus be with your company. sincerely a mother of 3 boys. *tr

I was told from a mechanic the car has either pcm or ecm problems. the car starts to die out when i'm driving it then i have to turn it off then restart it. it jerks really hard when driving it. the oil pressure low stop engine message comes on. it just has a lot of electrical problems and the mechanic told me the other impalas like mine are having either all the same problems or some of the same problems. recall

Two different outcomes but stem from the same issue. while trying to start my vehicle i get a click and care won't start at all. sometimes after several tries it does fire up. also when it does start it will sometimes stall. most recently while traveling didn't the interstate it stalled going 75mph leaving me to coast and disrupt 4 lanes of traffic.

The door locks malfunction when the temperature is above 80 degrees. when this happens you must use the key to unlock or lock the driver door and manually open the other doors from the inside. the remote key system is not effective when locking or unlocking the vehicle. i asked reed lallier dealership if there was a recall on the locks but it only applies to the "ss" model and not the lt, even though the issues are the same. the issue started last summer and has gotten worse this year, when the temperature is around 75 and below the locks function fine. the malfunction only happens when it is hot outside.

I was left sitting on the side of the road. i was going 70 mph on i-94 when the "service traction control" light came on, followed by the "engine power reduced" light, then something about "disabling throttle" sensor... my car shut completely down, leaving me to coast across 4 lanes of traffic on interstate 94. i've owned this 2008 impala for just about a year... i don't know what to do i received the letter about an extended recall back in december and i called gm because there's a stipulation of the amount of miles you can have on your car to have this problem repaired... because my car has 276000 miles gm told me there is nothing they can do, at that time i asked why this item wasn't recalled. i was told if i felt the problem called for a recall i should reach out to the national highway and safety commission. i don't even feel comfortable driving my car anymore... this is a death trap!

While driving at about 20-25 mph, i noticed a internal fire coming from the fuse box on the passenger side of the car

I got a jump after the engine light came on. took it to get ichecked they say its my ecm. what is that and is it related to that electrical recall. i was in park

The air conditioning actuators goes bad to a point where a knocking noise will start to come from inside the dashboard. this eventually will kill the electrical system and cause the car to cut off completely, even while driving.

Blinking airbag light that is unable to be cleared.

Issue occurred twice so far. service traction control error message appeared followed by reduced engine power. 1st time this occurred the car came to a complete stop and would not run. was on a small side street and only doing about 15 mph. i let the car sit after calling for a ride. car restarted and drove to dealer 2 miles away. 2nd time same set of error messages, car was doing 70 on the highway at the time and dropped to below 50 mph. drove to dealer. both times, repair was identified as being a defective acclerator pedal position sensor. 2nd time vehicle had 92149 miles on it. do not have the record for the mileage for the 1st time but it was about 1 year prior with estimated mileage of 77000.

Door locks will not lock or unlock. door locks have quit working one by one. front driver door only door with key lockable unlockable feature. therefore, doors can only be unlocked by unlocking driver door and crawling into car and manually unlocking all other doors. i have owned no other car that had this feature where out in less than seven years. this is a safety hazard not being able to unlock/lock doors. the locks don't work whether car stationary or in motion.

Reduced engine power message. this message came up after have car at mechanics for a repair on actuator. we took back to mechanic and he cleared message however message has appeared after a week of driving car less than 10 miles per day. mechanic said possible fix resulting in another $300 repair. the message came up while doing local driving around town less than 5 miles before it will appear

Reduced engine power message, faulty back door locks, heating actuator repairs. this is a revised complaint to one i also made for just the reduced engine power message. after reading numerous complaints on here i have found that my car has several of the issues not just reduced engine power. i am most concerned with the car cutting out while driving due to the reduced engine power however we also have locks that don't open/lock with remote which has been going on for the last 3 years and since last winter heater only blows cold air until you accelerate the car. this month we had car repaired for a knocking noise coming from under glove box while car was running or shut off. mechanic diagnosed as a new actuator and did repair. this however did not repair the blowing of cold air and also this is when the reduced engine power warning started. i am a former gmac employee and have had gm vehicles for the last 15 years. i am so disappointed that there are so many problems with this make/model and that gm has not issued a recall on these.

Vehicle stuck in park unable to shift from the parked position. parked in front of my house went to go pick daughter up from school and couldn't shift gears.

While driving my car my car stalled as if it was in neutral. i stopped and tried to put the car in park, but nothing happened. i tried reverse and the car wouldn't move. it crakes up but there are no shifting of gears. i had to replace my gas tank as well as my pedals for this car. please help.

My key is stuck in the ignition. i am forced to disconnect battery & hope that nobody goes looking through my car or attempts to steal it. my second complaint is knocking sound coming from my hvac. it will happen wether car is in or off.

Rear passenger door locks do not function electrically when the vehicle is warm. automatic lock function when the vehicle is placed in 'drive' does not function under these circumstances. due to the position of the manual lock releases, it is very difficult to manually unlock the rear doors manually. in an emergency situation, if the rear door locks do not function, it can delay escape from the vehicle.

This is the third time since i bought this car (new) that the wiring on the shift lock has failed. the problem is well reported on the web for 2007 and 2008 impalas. the car has been towed each time and wires fixed . the cost has been running #300.00 to $150.00 and the fix last about two years,i have googled the problem and found many others suffering the same problem,yet your recall log shows nothing.

I recently had a vent actuator fail; the sign was a loud clicking noise coming from the failed vent actuator located behind the glove box. according to the information that i have been able to gather, there are 4 vent actuators located behind the dash of the vehicle. these vent actuators seem to fail on a regular basis from complaints that i have been able to review on the internet. these are $25 parts, however the labor costs are ridiculous; $300-400 per vent actuator. if these vent actuators fail at random times, that is at a cost of up to $425 for each visit to the dealer, and there is no guarantee that they won't fail once again. chevrolet is fully aware of the problem, according to their own web site. however, they continue to charge the owner of the vehicle these outrageous fees. i am seeking assistance in having chevrolet replace all the vent actuators with a quality product; nothing like cheap chinese plastic. in addition, they need to quit passing the labor costs onto the owner for a problem that they refuse to address.

Came to get in and unlock car when i noticed only the front passenger door unlocks. had to climb through the car (while 5 months pregnant) to unlock both backseat doors for my niece and infant nephew to get them in the car. the 3 locks, besides passenger front, only work maybe once a week randomly. i have my first child on the way in november, and now i have to worry if i will have to set my baby on the ground during winter to climb through the car to unlock the back door manually.

Driving on the highway during rush hour thru a construction zone my car gave me the engine power reduce then not even a mile down the road the starting disabled service throttle message came then the car stalled with no shoulder to pull over on. sat for about maybe 5 min then made it home. not it happens more frequent. took to the gm dealer to get it diagnosed and they told me they couldn't find a problem with it. so basically spent 40 bucks to hang out at the dealership for them to tell me nothing. they even checked my vin and no recall.

When changing temperature in vehicle, a loud clacking noise is heard for up to 2-3 minutes even if vehicle is turned off. service air bag light and stablizer trac service light comes on. oil leak under car. only 55,000 miles. can be heard 50 years away from car it is so loud. 2008 chevrolet impala lt

Random clicking and ticking rather it's on or off.

Door locks will not lock/unlock with fob or lock/unlock button and the more you press the button the weaker the signal to lock/unlock the doors become. very dangerous! *tr

While driving on the highway (60mph), without warning the car slows to 20mph and the check engine light comes on with an error message about the traction control. extremely dangerous situation, but i was not rear-ended. *tr

I started my car and the rpm's went to 0. message stated "service traction control" and engine power reduced". when i looked up information online i noticed many people had the same problem with chevy/gm cars.
