I purchased this vehicle in a chevy dealership in palatine, IL. [xxx]. 50k miles a chevy Impala around 38k total with taxes and all. A month later I had to pay 200 for a diagnostic at the dealership to check an issue with the steering. They said nothing was wrong with it and it was just the floor mat making contact in the floor. When I returned home, I had the same issue occur again. I retook it and they wanted another 200 dollars. I complained to the seller of this vehicle, and he agreed to waive these 200 dollars. When it was rechecked, it was found out that it actually had to replace the wheel barring's on the front. It was around a 2,000$ job I have the receipts, and I actually didn't pay for anything at the time due to warranty. I also have been up to date with transmission oil, engine oil, fuel injectors, etc to keep the car running smooth. As of 01/2025 I started having issues with the transmission, the gears were very jumpy and very unsafe to drive. I called the dealership and I was told the warranty had a expire a month before. I had to call the bank to find out this telephone number since the dealership never responded back. The number I was looking for was the warranty which my contract that was given from the dealership coincidence didnt have it. I had to reach to the bank and ask for a new contract. I called them and was denied due to the time that has past and was out of luck. I took it to a mechanic for a transmission rebuilt and cost me 3,000 which im still paying off right now. It was repair around [xxx]. Now I have an issue with the power steering. I also have a check engine light now. I am in the process of taking it to the transmission job to look at it but most likely wont get fix. I now have to invest around another 1,500+ for these new jobs. I dont have that much now and its costing me a lot of headaches pain money and time and many more things. Gm wont do anything about it and I still have to pay550 a month for this vehicle. Idk.

While I was driving I had to stop on a hill and when I pushed the gas to accelerate it wouldn’t move the engine just revved up and hasn’t moved since just when you push on the gas and the rpm’s go up to 5-6 and it will move maybe a foot or so. There was no warning or messages that appeared before this happened and even now after it’s happens and it’s not showing any code to what’s wrong with it. It affected my safety and others because it wouldn’t move while in the middle of the road and I could have got in to a serious car accident because of it.

Since vehicle purchase in 2018 there is a shifting problem with the transmission. I have paid for shifter repairs and still the problem exist. While driving the car gets stuck in gear and hard to accelerate. The issue happens at various times without warning. There has been two instances that could have led to potential accidents. Upon spraking with and researching other Impala owners, this is a common problem in the 3. 6 engine Chevrolet Impalas but nothing has been done. The dealer has a plan to determine but it has always cost $1500+ to the customer.

A piece broke off and had fallen off of transmission when stopped at a redlight when put in gear car didn't want to move had to manually shift to get off the road and towed it home. The piece that broke fell into pan when changing transmission fluid. Believe it's off flywheel possibly forward band.

The brakes continue to malfunction I am unsure if a previous recall was fixed properly or not the chasis electrical system has been fixed with electrical tape only the transmission and stability track and anti lock brake system error light with go off from time to time when it does and the more it’s driven the worse the issues get these are all recalls and the problems still persist are we confident that the recalls have been corrected.

Transmission shifts hard after engine warms up.

While driving vehicle warning light service stabilitrak. . . . Reduced engine power comes on. Vehicle then slows and can not drive over 20 to 30 mph. This has occurred randomly at highway speeds while driving on interstate in traffic. Sudden reduction caused traffic to have to slow quickly and almost caused a collision.

Fourth time I had submitted this text so this one will be vague. I've had to repair my stuts and shocks and brakes to my vehicle due to ongoing issues with tires while divingand hitting small speesbumps and potholes. I did replace low performance tires and still was an issue with my struts and shocks when I drive causing me to hit a bump or a small hole and diverts me to the next lane of ongoing traffic also I had to my battery replaced twice. To find out that it was only due to corrosion and the battery cables slipping was frustrating cause I did replace the battery and key fob battery already. Car wouldn't start and when it did it took forever hours to restart and engine still seems to get bogged down in ongoing traffic. Which was the prior issue no power no matter how hard I press the gas. I took to autozone and they did a reading which came back that everything was okay including the battery which was obviously not okay. It was leaking fluid and I have already replaced year and half ago due to same issue. They cables seem to slip over time on its own. What to do? thank you for your time to look into this issue. Kindest regards.

Stability control light comes on which puts the engine in restricted power abs and brake light comes on front driver side brake continuously holds on when trying to accelerate.

While driving or idling (car in d/m, both automatic and manual), the car will rapidly shift to park and then back to where the shifter was set, usually in a lower gear that slows the car down or prevents acceleration. The transmission or speed sensor could be an issue. This can happen in rapid succession 3-5+ times in a row, which has led to a drop in speed from 65 mph to 40 mph, especially dangerous at faster speeds on a highway or when deceleration is occurring more quickly, like going up a steep hill. I am unsure what indication there is for cars that are behind me, but they have had to slow down or pass me in some instances to avoid hitting me. If it happens while turning at a 2 way stop or on an entrance ramp, my car might not accelerate fast enough to merge into traffic. There have been no lights on the dash, and the dealer has not been able to identify the issue when I have taken it in.

Been having transmissions issues since I got the car and nobody can figure out what is wrong, changed the fluid, added lucus, sounds like it’s reving while driving (foot not on gas, cruising).

There is a current recall on chevy Impalas with the trans mod control system but my VIN number is not apart of the recall but my car is doing everything that recalls states. The recall number is 14v614000. The recall date 10-01-2014. My vehicle is 2014 and I have only had it for 2 years.

I was sold a used car w/ undisclosed accidents. Had many issues within first few weeks. Had transmission cooler lines replaced after they burst. Radiator, compressor, condenser, and much more. Then the airbag light came on. Dealership said connectors were bad. Fixed it. Light came on again. Took it in to dealership. They had it for over two weeks. The gm for all the dealerships told me the vehicle was not unsafe and told me lies. But the service girl confessed she no longer had access to my vehicle or my file and her boss and the gm had taken over working on it. She then told me they pulled Ford model air bags from my chevy Impala. Now the light has come on again. I do not feel safe or rust the dealership to fix it properly.

The gas petal sensor is reading a code p2138 (accelerator petal position sensors 1-2 not plausible). My father has changed the petal not once but twice and erased the code but it keeps coming back. Also getting a p0172 code as well. A cheverolet dealership has been called and the representative rushed me off phone saying there was not recall for the car. Car was taken to an autozone and the codes were still coming up. Engine warning light goes off and on every 3 to 4 days after being cleared, then will get a reduced engine power message will appear. Messages warning lights and symptoms started 3 months ago.

Was driving and lost power steering. Message came up stating power steering service drive with caution. Drove straight to dealership.

While driving from work the car did a quick jerk and the stabilitrak, abs and check engine light all came on all at once. As I pulled into my workplace the car lost power to the engine completely while displaying action required on the lcd screen. The brake and steering wheel became stiff and it was hard to control the vehicle. It took 10 minutes for me to regain power and control over the vehicle that again after leaving work stopped on the highway.

Was driving when the service power steering message came on no code to be read on it unable to drive or turn.

Wiring harness has got hot and cause a short not getting fuel and more.

Today, 6-12-2022, driving on us highway 80 at 65 mph headed toward phenix city, al from columbus, GA, the the engine shuddered, then the "stabilitrack service light" came on, along with the check engine light, and a message for "reduced engine power. " then, the engine suddenly cut out as I was going uphill between the riverchase exit and the summerville exit. Luckily, I was driving and not my wife. I was able to glide the car back to the right shoulder of the road under zero power, and shut the ignition down. Cars were passing me at 65-75 mph, and I was very fortunate not to have caused an accident. After sitting there for about 5 minutes in 96 degree heat and my wife freaking out in the passenger seat, I restarted the car and eased it to the summerville exit, and slowly drove home, about another 6 miles. We were damn lucky not to have been hit by another car, as this happened on a what is essentially a freeway. After researching this , it seems this is a common problem being reported on this model, the chevy Impala. I'm sure Chevrolet knows about this. . . The company should be forced to recall this car model and fix it before folks start getting killed due to total engine failure. . . Especially at a high speed like I was driving.

The "service stabilitrak" light and engine light has returned making the vehicle non-operational once again. I have spent over $2500 in the past 12 months at an authorized chervrolet dealership attempting to repair this exclusive, patented general motors safety system, however, the system continues to malfunction. I cannot be the only owner of a gm vehicle with this frustrating, expensive issue. Please assist with a recall and/or inquiry to gm/Chevrolet. Previous NHTSA tracking number 11444992.
