POWER TRAIN
When shifting from park to drive after the engine start none of the gears on the shifter engage. All positions are in neutral except for park. When shifting from park to any gear the engine revs when the throttle is pressed but the vehicle will immediately roll whichever way the ground is inclined. The power brakes won't engage thus forcing the driver to put their entire weight on the brake pedal to stop the car. A fix for this issue is described in General Motors Service update N2424466290 which identifies solution as replacement of the clutch piston housing. The Dealer will not fix the problem because my VIN # was not on their list of vehicles to fix. This is a safety issue because it happens randomly and surprises the Driver when the car suddenly starts coasting in whatever direction the ground is sloping. In my case the car suddenly rolled into a lane of traffic backwards in a Costco parking lot. Fortunately no cars were coming as I struggled to apply enough force to the brake pedal to stop the car. Another time the car decided to back out of the garage before I could react with either the brake pedal or the e-brake.(The electric emergency brake would not work during this incident). Please expand the manufactures known solution to all vehicles with this issue regardless of VIN number.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
On April 13, 2025, around 5:00 PM, while driving, a warning appeared on my dashboard: “Forward Collision System Reduced.” Not knowing the full meaning but understanding it could pose a safety risk, I immediately contacted the dealership the next day. I informed them it was urgent, but no one followed up. Days later, I called again and was told to bring the vehicle in. When I did, I asked about a rental vehicle (previously provided during another incident), but was told no rental would be offered until the car underwent diagnostics, which would take 3–4 business days. I explained I rely on this vehicle for work and couldn’t leave it that long without transportation. I was dismissed without any explanation of the warning. Despite reporting a system warning related to crash prevention, the dealership allowed me to continue driving. No inspection was done, and I received no help understanding the message or resolving the issue. On May 8, 2025, I missed a stop sign and collided with another vehicle. The crash caused major damage and totaled my car. The Forward Collision System never activated—no alerts, no automatic braking. The vehicle was advertised to include safety features like collision prevention that would warn or stop automatically. This failure contributed to the crash. I was cited for failing to stop and driving without insurance. I believe the system malfunctioned and that the dealership acted negligently by not inspecting the vehicle promptly. The issue has not been confirmed by the dealer because they refused to inspect it. The vehicle may still be available for inspection, and I plan to have the black box (EDR) data analyzed. No warning lights appeared before April 13.

I received a email from carfax stateing the truck had diagnostic testing and is the transmission in the engine system. It’ll start up but you cannot drive it. It shows that are passed the state inspection on June 27/2025 stating that the truck passed the inspection how the truck went past inspection and it’s not driveable and I don’t have it. There’s no way that’s fraud you gonna say that the truck pass inspection when you can’t drive it normally when you go get a state inspection and once they do it and it pass they give you the keys and put the sticker on it. In this case the truck is still at the dealer and it’s not driveable. You can’t drive it. It’ll start up. They change the oil rotated to tires but it’s not driveable. You can’t drive it.

ENGINE
The turbo went out on the car for absolutely no reason. Message popped up on dash board saying "Engine power reduced". I have seen this happen to many many many other card across the country. It does not many how many miles are on the car. some Ive seen 25k and some ive seen at 60k. Shouldn't Chevy be recalling and fixing the part? Seems unfair to me as a consumer. Who has thousands of dollars to get that repaired?

FORWARD COLLISION AVOIDANCE: WARNINGS
Two weeks before the accident, a warning message appeared on my car’s dashboard stating: “FORWARD COLLISION SYSTEM REDUCED.” Naturally, I was concerned. I immediately contacted the dealership, but they failed to return my call. I followed up a few days later, and they told me to bring the car in the next day. When I went in, I explained my serious concerns. They told me they would need to keep the vehicle for 3 to 4 days just to diagnose the issue and that no courtesy car would be provided during that time. I made it clear that I rely on my car for work and had no alternative. I even pointed out that the dashboard warning was a diagnosis in itself. I asked to speak with a manager and repeated everything. He simply echoed what the advisor had said—and I was sent away with the vehicle, unresolved and still potentially unsafe. On May 8th, 2025, around 5 PM, on a clear day, I missed a stop sign and collided with another car. I firmly believe the forward collision system malfunctioned and that this accident could have been prevented had the system worked properly—or if the dealership had properly advised me not to drive the vehicle after such a critical warning. In my view, the dealership was completely negligent, and the manufacturer was aware of a defect in the system and failed to act. I also contacted the finance company, Santander Consumer USA, to alert them in case other customers have the same vehicle with the same risk. They showed no concern. It’s important to add that I did not choose this car myself. Santander limited me to specific dealerships and pre-approved vehicles. I had no freedom to select a car I truly wanted—perhaps because the available options were already considered poor choices. I believe a recall is necessary. I lost my vehicle due to this negligence, and I want to prevent this from happening to someone else. PS: I also had another message on 02/15/2025 that said: ENGINE POWER IS REDUCED, and apparently the dealership took care of it.

hift to park The vehicle began to display 'Shift to Park' on the display even after the vehicle was in the park position. By shifting back out of park and back into park, but that became less effective as time went on. The vehicle will not shutdown fully when this warning is displayed and therefore can cause a battery drain condition, which can result in a safety risk returning to a vehicle with a weak or dead battery. Vehicle has only 23,478 miles. In researching to understand the problem, I discovered that there are many instances of this same issue occurring at about the same time period, as well as there being several class action lawsuits on the identical issue, which shows that it isn't isolated.

ENGINE, FUEL/PROPULSION SYSTEM
Month of June of 2024 I purchased 2021 Chevrolet Trailblazer LT with 31k miles on the odometer I had to service my vehicle and had to replace the fuel pump, took weeks to get in due to the strike that took place, Chevrolet will not back behind their employees nor their consumers. They only honored me 15pts on my vehicle, a few months pass and more issues arise one being the manifold sensor (a) and then another two days on the road the wiring harness thankfully my car was under a secondary warranty and I paid $200 per repair, although this became a very costly month being $600 car payment and $400 in repairs in a matter of a few months owning the vehicle, I am having similar issues again with the wiring harness a year later.

POWER TRAIN, ELECTRICAL SYSTEM
The vehicle began to display 'Shift to Park' on the display even after the vehicle was in the park position. This started periodically over a few days, but then became a regular occurrence within a week. At first this could be resolved by shifting back out of park and back into park, but that became less effective as time went on. The vehicle will not shutdown fully when this warning is displayed and therefore can cause a battery drain condition, which can result in a safety risk returning to a vehicle with a weak or dead battery. This occurred at 37 months of ownership with ~28,100 miles on the vehicle. In researching to understand the problem, I discovered that there are many instances of this same issue occurring at about the same time period, as well as there being several class action lawsuits on the identical issue, which shows that it isn't isolated. Further, the cost of this repair is a replacement of the shifter assembly at nearly $700 on a $24,000 vehicle less than 3 years old, because the failed inexpensive switch isn't repairable. Repair information is available, but the system isn't allowing for an upload of the files.

The contact owns a 2021 Chevrolet Trailblazer. The contact stated that while attempting to remove the key from the ignition, the key remained stuck in the ignition cylinder.

POWER TRAIN, ENGINE, VEHICLE SPEED CONTROL
Almost every time I shift from park to drive and take my foot off the brake my car jolts forward a couple feet/inches to take off by itself in a manner that it should not. This has been going on since I got the car brand new and have had it just over a little over a year. I try to be as careful as I can with it and mentioned it to the Chevrolet dealership that does all my maintenance on my car. They are not sure what is causing the issue, but on 05/24/2025 I was attempting to get ready to get gas and needed to pull up slightly a little bit more and when I shifted to drive my car jolted forward and hit another vehicle. No damage was done to the other vehicle or mine, and the gentleman was nice and said it caused no damage for either of us but my car cannot keep doing this. Sometime is not right with it to be constantly jolting forward as soon as I shift to drive and take my foot off the break peddle to go. This could have been a lot worse had a human been in front of me and I do not want that to ever happen.

VISIBILITY/WIPER
On 5 separate occasions the windshield wipers have stopped working while in use. The wipers returned to the home position and would not turn back on. Each time I had to get safely to the side of the road and stop shut the car off while travelling at highway speeds. After 10-15 minutes the wipers began working until the next incident. My safety as well as others on the road I was travelling were put at risk as I was not able to see out of the front windshield. The vehicle has not been inspected by anyone other than me. This is the fifth time this condition has presented itself and there were no warning lamps, messages, or symptoms prior to each occurrence.
