| Jan 2024 | VEHICLE SPEED CONTROL,UNKNOWN OR OTHER | On Jan 22,2024 while driving on the interstate the speed was unexpectedly instantly reduced, the car would not accelerate over 60 mph and the service engine light came on, the car was safely driven off the highway then towed to the dealership. My safety as well as the safety of other drivers on the highway was at risk when the car suddenly decreased to 60 mph from 75 mph which could have caused a collision. The inspection at the dealership confirmed that the issue was the intercooler for turbo found moisture/oil frozen in charge air cooler causing restriction in induction system, and the part design has been updated to help prevent the issue from happening again. My issue is that if the part has been updated that means that GM is aware of the issue and should be responsible for the cost of the part or there should have been a recall on the part. The consumer should not have to be responsible for the cost of the part or the repair to the vehicle. It is unknown if the part was inspected by an insurance representative but it was inspected by the dealership where the car was purchased. There were no prior warnings, lights or lamps occurring before the date of the incident. I feel like Gm should cover the cost of the repair, the total cost should no fall on the consumer and the vehicle manufacturer should take responsibility for the defective part. | Crash: No Fire: No | Unknown |

| Dec 2023 | POWER TRAIN | I have an ongoing issue with the shifter not communicating to the ECU that it is in park. I put the car into park, dash board shows in P (park) and transmission is in park (ie won't move forward with brake released) and when I go to turn the car off I get message that car is not in Park. To remedy this I have to smack the back of the shifter forward sometimes 5-15 times and from light to moderately hard pressure to get the ECU/sensor to realize it's in Park. The shifter was replaced by a Chevy dealer 2-3 years ago but the problem started again. I believe there needs to be a recall due to the same issue ongoing [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) | Crash: No Fire: No | Unknown |
| Nov 2023 | POWER TRAIN,ENGINE | Transmission Surge Accumulator System Performance. The car fails to accelerate once it comes to a complete stop, traffic lights, etc. The car will rev up to 5000 RPMs but will not reach 10 mph. This causes problems when driving and I was almost hit on several occasions (more than 8 times) on my drive home to be safe again. The car was taken to the dealership and was reported to have been fixed, after paying a $100 deductible, but only ran properly for one day. Again, I was almost hit 5 times while driving back home, after the repair was made. The check engine light came on after the car presented issues, as I was out running errands, the car was losing power and was not performing well. About 20 minutes after the initial issue, the check engine light came on. I took the car to Auto Zone where they were able to run the diagnostic that came back with the code, P171D Transmission Surge Accumulator System Performance. This took place twice in one week, with the dealership fixing the issue on Tuesday and it failing again on Saturday (after the car sat idle for 3 days, while I was on vacation). | Crash: No Fire: No | Unknown |

| Oct 2023 | SERVICE BRAKES,ENGINE | I was driving the vehicle on a busy road and a message came up on the display above the steering column saying Engine Power Reduced. I went to brake and was unable to push the pedal in as it was extremely stiff. There were vehicles around me and I tried to use both feet and stand on the brakes and was able to get a little bit of movement but the car still didn't slow down. I had my significant other and brother-in-law in the car and we were all horrified we were going to get into an accident. I turned the hazard lights on and was able to steer to avoid hitting several vehicles and when traffic finally cleared I was able to get over and off the road into a gas station that was uphill and allowed us to slow down and finally stop because I put the vehicle in neutral tried the parking brake which got us to a complete stop and shut the vehicle off. There had been no previous issues with the brakes or messages such as the one that came up right before this issue occurred. The vehicle had to be towed and the repair shop told me the cam driven vacuum pump failed which caused the brake booster to not function. When this failure occurred, it damaged the intake and exhaust camshafts, crankshaft, and several other components. The cooling system and oil to be flushed out as I was told there was metal debris from the damaged parts caused by the vacuum pump failure in the fluids which had been all completely flushed and changed including cooling system, transmission fluid, and oil change The total cost of repairs as a result of the vacuum pump failure setting off a Domino effect of damage was $3536.40. | Crash: No Fire: No | Unknown |

| Oct 2023 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER | My turbo failed while I was on a very busy highway, causing me from going 70mph to 35mph in a matter of seconds and almost being hit. This put my life and my friends life at risk since we were in the left lane. Now that I’ve been fighting with the dealership ti help make this right they found a GM warranty that fixed and updated electrical sensors. We fixed that first because at the time we thought that was what it was. My turbo gave out again up in the mountains almost killing me and my friend a second time on a busy road. We made it to a parking lot and called a tow truck. Now the stabiltrak is showing up and the car refuses to start, it makes a whooshing sound and doesn’t start completely. (There is fuel, oil, etc). I was sold an unsafe vehicle and now I’m stuck paying 500$ a month for a car that’s unsafe and refuses to work even when it’s been fixed. The dealership is refusing to help me, I’m at a loss. I still owe 18k and I can’t have an in working car sitting in my apartment complex, it will get towed and cost me more money.. I need help. I was sold a car that almost killed me twice and no one seems to care. | Crash: No Fire: No | Unknown |
