SERVICE BRAKES, HYDRAULIC
The contact owns a 2023 Chevrolet Trailblazer. The contact stated that while his wife was driving at an undisclosed speed, the brake pedal felt extremely firm and was difficult to depress. The contact stated that his wife needed to anticipate the stopping distance to apply enough force to the brake pedal while stopping the vehicle. The vehicle was taken to the dealer on several occasions, but the technicians continuously stated that there was no failure with the vehicle. The vehicle was taken to an independent mechanic and was diagnosed with an inoperable brake master cylinder. The contact was informed that the brake master cylinder needed to be replaced. The vehicle was taken back to the dealer with the information; however, the dealer stated that the brake master cylinder replacement was not necessary. The vehicle remained unrepaired. The manufacturer was notified of the failure. The failure mileage was 40,000.

The shift assembly is going bad and causing a Shift to Park error that GM is aware of. They have issued a Technical Service Bulletin about this exact part. The error code will cause the battery to run down leaving me stranded. The dealer has inspected the vehichle and ordered the necessary part to replace it. The vehicle has not been inspected by the manufacturer, police, insurance representatives or others but is available to have an inspection done. There were no warning lamps for this other than the Shift to Park error showing on the display when the car has been turned off. These error messages started happening around August 1, 2026.

When I shut off the engine, it says “Shift to park” and the car will not turn off. To get it to turn off, I have to turn the car back on (usually multiple times), until it recognizes that it IS in park.

I was driving down the highway when the 3 bolts holding the exhaust under the car broke off. My exhaust was dragging down the highway until I could safely get pulled over. The bolts are welded in of course so you can’t just put new bolts in you have to replace the whole catalytic converter, which is a pain to do unless you take it to the dealer and pay $2000.

ELECTRICAL SYSTEM
I am submitting this report regarding my 2021 Chevrolet Trailblazer because it has been experiencing the "Shift to Park" issue described in the GM bulletin 19-NA-206. Even when the vehicle is shifted into Park, it intermittently displays a "Shift to Park" message and does not recognize that the transmission is in Park. This issue has been ongoing and has not resolved despite normal use of the vehicle. It is frustrating to deal with on a regular basis, and it appears to be the same condition addressed by GM in Technical Service Bulletin 19-NA-206 that is available to view on the NHTSA website. I believe the NHTSA should push General Motors to issue a recall for this problem rather than relying on a Technical Service Bulletin. The issue appears to affect many GM vehicles, and owners should not have to bear the burden of repeated repairs or diagnosis for a known defect. I respectfully request that the NHTSA investigate this issue further and require GM to provide a permanent remedy through a recall.

Shifter does not recognize its in park, from what I read this affects thousands. Why am I having to sit in my car for minutes at a time? is Chevy not required to handle the fixing of that switch. What a subpar design team they have. I just had to cough up over $800 to fix rusting because of shit wheel design that doesn't protect those components. Absolutely unacceptable to have consumers not only buy a car but then not issue a recall over the switch just inside the console I guess they want to con thousands to pay for a new shifter?

Vehicle displays Shift to Park when vehicle is in park & you push the ignition button & audible chime occurs. Apparently this is a known issue for Chevrolet Trailblazers & Buick Encore GX vehicles model year 2021 & newer. You have to either wiggle the gear shifter several times & depress/wiggle the shift lever button in order to turn off the vehicle. Sometimes it takes 5 minutes to get it to work.

My trailblazer will not shift properly into drive from park or reverse. GM calls this a "loss of forward motion" or "delayed forward engagement" in their service bulletin TSB-24-NA-009. It is a safety issue because you never know when or how long the vehicle will take to engage and allow forward movement. This causes issues when leaving a parking spot or a driveway, especially on busy roads. If the car will not move forward, my family is stuck in the road until it finally engages into gear and allows forward movement. When this occurs, the vehicle engine will shutter and not allow any forward movement. I usually have to move the drive selector back to park and back to drive again. This creates an immediate and unreasonable safety risk because the vehicle will not move for several seconds while I am sitting in traffic. This generates a P2714 code. I had the car looked at by a GM dealer as well as an independent transmission repair shop and both indicate it will likely need a new transmission. GM is fully aware of the defect and has issued a service bulletin, TSB-24-NA-009 to instruct dealers how to diagnose and repair the problem. The bulletin proves a widespread engineering or manufacturing flaw exists. However, GM is treating this as a maintenance issue rather than the severe safety hazard that it is. It is my understanding, GM has since abandoned this transmission on the newer models, further indicating that GM knew these transmissions were not designed well. I am requesting the NHTSA office cross-reference my complaint with GM TSB-24-NA-009 and upgrade the component defect to a mandatory, manufacturer-funded safety recall before it causes a collision or fatal injury. Thank You

The car showed an error message saying shift to park when trying to turn the car off. The car was in park and showed in park on the dashboard & shifter but the error message still said it wasn’t in park. While this error is showing it will not allow the car to shut off or lock doors. I have a little over 19k miles on this car and should not have this issue. After researching this has been a know issue with their vehicles for years and it still has not been addressed.

purchased a brand new vehicle in 2022 Since purchase I have had multiple issues with said vehicle for which I will list. I understand vehicles will and can have issues but there is no excuse for all the problems I have had to deal with a new vehicle. A. Muffler has fallen off 3 times and replaced all 3 times During the leakage part of why it was not fully disconnected every time I was driving the car I was inhaling the fumes because the brake was under the seat of the car driver side B. Emergency Blinkers on dashboard had to be replaced because they overheated and melted C. The vehicle has 13,000 miles And now I am getting error messages that say the car needs to be put in park and won’t shut off and just keeps having a buzzard ring when the car is actually in park

Vehicle has 67,000 miles and suffered a catastrophic CVT transmission failure, documented by dealership diagnostic code P2714. The transmission severely slips and exhibits a dangerous 15-second delay to engage forward gear after shifting into Drive. More critically, the vehicle suffers from unpredictable engine stalling. The car completely shut down and stalled in traffic while trying to accelerate into a driving lane after shifting. The vehicle did not trigger any dashboard safety warnings, limp mode, or "Reduced Engine Power" messages prior to shutting down, causing an un-warned loss of motive power on a public road. This creates an immediate, severe risk of a high-speed rear-end collision. General Motors has acknowledged internal CVT chain slippage and hydraulic failure points in Technical Service Bulletins 24-NA-009 and PIP6033 but has not issued a safety recall.

When putting the vehicle in park an error displays, SHIFT TO PARK, and the vehicle does not turn off completely and will ding although you’ve put it in PARK. This has been happening for well over a year and the dealership says it’s a known issue but not a recall. There are times it’s taken up to 25 mins that I’ve had to sit in the vehicle to get the vehicle to turn off by wiggling the shifter or just putting it in drive and back into park, hitting the shifter button, etc. I’ve had to let the battery die in the very beginning because I panicked when it happened and had to get into work. My son has been late to class when he uses the vehicle to drive to school. It’s been such an inconvenience and a safety issue because the vehicle doesn’t turn off and won’t lock and who knows if it’s really securely engaged in the park position or not.
