This is the 3rd time for he same issue. After a cold start the engine will start missing on a cyl which results in a huge decrease in power and running rough. This last time, engine light came on. Just like the other times, if you stop and restart the car, the issue goes way. Took to dealership and even though the engine light came on, no codes and they couldnt replicate the issue and nothing was done.

While I was driving on the road, the vehicle has shut off completely as I approached a complete stop at a red light. I attempted to turn on the hazard lights but unable to start the vehicle, until it is jump started it will start, I was able to continue driving. Once I arrived at home and I parked the vehicle, it completely shut itself off and I was unable to restart the vehicle. After several attempts to start the vehicle it just started again. Which I was able to lock the vehicle with the remote. This has happened several times now on different dates.

The check engine has come on three times already since I have bought this vehicle... everytime the code is for emissions system. We have replaces the valve and the canister for emissions and the engine light still comes on.. also the shift to park issue.

Car went back to dealership Monday because of problem I had last year. Lights comes on in dashboard : stabiltrack, engine icon, reduced steering, low fuel. On my way to work Monday just made it out my driveway and started up the hill and the lights started flashing. Brakes had to be pushed ask the way to the floor for it to stop rolling back down the hill. I let it roll back to get the car out of street. The car wouldn't turn off when I pressed the start/stop button. Pressed the button again the car turns off but all lights are on in the dash. Press button again and lights go out but the start button is lit. Shift to park comes on dash. It's in park. Couldn't get engine to turn on. Couldn't move gear shift that has no lights on column or dash to tell what gear it's is in. Got car towed to greenway in tuscumbia, al. Had to find a ride to & from work because they didn't have a loner.picked car up Tuesday(they said the battery needed to charged & there was a recall they fixed) made it home ok. Went to store, no problem. Got in car to go to work Wednesday and it starts acting up again. And when I got out of the car at work, there was smell like the brakes were really hot. Called dealership didn't get through to service but guy said he would get my number & have someone call, no one did. Got in car to leave work the lights started again but I was able to come home with no further incidents. The engine icon was still on though. I'm sick of this car! and I'm tired of going to the dearship every couple of days or every 2 weeks! buy this lemon back!

I was driving in a neighborhood about 15 mph. My car began to shake, the engine light was blinking, stability track light was on, and an icon came up saying that the 'service stablitrek.' I had little control over the steering and I felt no traction while trying to pull over. I also have a problem where the car prompts a shift to park, even though my car is in park.

Since July 2019 my vehicle has continually shown a check engine light with the message, power engine reduced on the dashboard. When this occurs, the rpms increase drastically and vehicle can not go over 30 mph. This has happened on highways and main roads. It is very dangerous because I can be going 65 mph on the highway and all of a sudden it drops down to 30mph. This has almost caused accidents multiple times. I have attached multiple service records where I have had the vehicle worked on, but yet the issue still occurs at anytime. The vehicle is very unsafe to drive. There has been recalls on this issue and although he dealerships say they fixed it for my vehicle, it still occurs. I have contacted GM and have not gotten an answer or had the problem resolved and it has been over a month I have been working with them. There last reasoning for not giving me a resolution was because they were waiting on service records, yet I called the dealerships and had the service records in less than an hour.

On 4/5/2020, while driving on a side street, the car lost propulsion. It read engine power is reduced and stabilitrac had activated. This has occurred several times prior. My very first encounter was on a major highway (I-270) the car has been serviced (per recall) on two separate occasions. It has done the very exact thing at least three (3) times subsequent of the recall mandate. Every time I attempted to restart the car the motor will violently shake. I have made this complaint to General Motors, prior to this latest event on 4/5/2020, my complaint had been dismissed. I am being forced to operate this vehicle; knowing it poses a serious risk of accident or death to me and other motorist. Luckily, I was on a side residential street a few blocks away from my residence. However, this was not the always the case and this is a continuous event. I live within a 3/4-mile radius of baltimore's sea-port, train & truck terminal as well as interstates I-895 & I-95's (harbor and fort mchenry tunnel). I travel the I-895 tunnel to work everyday. After several recall attempts to fix, this car is still doing the same thing. Whereas, without any warning signs, it loses engine power and stalls while in motion. Included are onstar onboard diagnosis reports and service records after the initial recall servicing of the car.

Engine power is reduced warning and check engine light anti skid warnings come on.

- Highland Mills, NY, USA

At a stop light, when light turned green, pressed accelerator, "engine power is reduced" messaged flashed, engine and traction lights came on. Unable to accelerate over 25mph, RPM would not go above 3. recall maintenance for ECM was completed on 01/11/2020.

- Antioch, TN, USA

After my 'recall' reprogramming update on the ECM... a month or 2 later, I started to have loss of power issues while driving. Got home it sat for a couple of mins, then went away. Happened again. Had my car scanned to see what the code was, an 'apps' P2138 code, accelerator pedal position sensor issue. It happens while driving, when it happens cruse control turns off, and traction control light comes on plus the check engine light. This can be a safety issue while trying to merge onto highway traffic... this had happened to me several times... first time was after a long day driving, then a few days later after a very cold night. Then nothing, several hundred miles no issue. Then drove 120 miles and it happened again on 2-13-2020. And twice today 2-21-20202. It only happened twice during a turn.

The ECM and battery sensor malfunctioned on Dec 9. I found out that GMC has known about this for sometime. September 6, 2019 is documented on your site. I was notified from onstar after I passed the mileage for GMC to have pay for this problem.

In motion on highway at 60 mph, my car acceration shut down and I started losing speed even though I was pressing acellerator. At this time my car started to down shift and the more I stepped on the accellerator nothing happened. My car then turned off on the highway. I immediately shifted to park and started the vehicle again because I was in fear of getting rear ended. We have taken the car to the dealership 4 times for them to fix it and the last time, they said there was nothing wrong with it. We still have exceleration issues with this vehicle. We got a recall notice of software from Chevrolet but the dealer ship is unaware of the repair and I do not believe they can correct this problem. We bought this car new and it has been in the shop 4 times for this recall. We wish to receive a new car for safety reasons. We are taking the car to the dealership again today but I am afraid to drive the vehicle.
