Chevrolet
Trailblazer

The three bolts at the flange attaching the muffler to the upper muffler sheared off due to rust and the whole rear muffler fell off when driving the car on an interstate. Car is 3 years old and at the time had 65,000 miles. The bolts used are of poor quality, and to make matters worse, there is no exhaust hanger near this flange so the muffler is supported at the front by just this flange. Poorly designed by GM.

I am reporting a recurring “Shift to Park” malfunction with my 2022 Chevrolet Trailblazer. When I shift the vehicle into Park and attempt to turn it off, the dashboard displays a “Shift to Park” message, and the vehicle remains in Accessory Mode rather than shutting down completely. The vehicle continues drawing electrical power and the battery drains overnight. This condition poses several serious safety risks: 1.The vehicle may not consistently detect or hold the Park position, creating a potential roll-away hazard. 2.It prevents the driver from shutting off or locking the vehicle, leading to security and electrical safety concerns. 3.If the vehicle remains powered in an enclosed area, it increases the risk of carbon-monoxide exposure. I understand this issue has been widely reported by owners of late-model GM vehicles, and appears related to a defective park/position switch or shifter assembly. I request a thorough investigation, appropriate repair, and confirmation whether this defect falls under a service bulletin or recall.

The contact owns a 2022 Chevrolet Trailblazer. The contact stated that while in park(P), the gear failed to shift into the intended gear. The contact wiggled the gear shifter for the vehicle to recognize that the gear shifter was shifted out of park. The shift to park error was displayed. The vehicle was taken to the local dealer, but was not diagnosed or repaired. The manufacturer was contacted, and referred to the NHTSA Hotline. The failure mileage was approximately 32,700.

Vehicle displayed "Shift to Park" error and would not shut off. This occurs after the shifter is placed in the park position. By any standard, a defective component that prevents the car from being shut off is an extreme safety concern and needs immediate attention. Additionally, the instrument panel remains illuminated and the aux power items continue to function. This has happened multiple times and has drained the battery on several occasions.

The exhaust and muffler completely detached from the catalytic converter/exhaust manifold while driving down the road. If we were driving at a higher rate of speed, the exhaust pipe could've caught on any imperfection on the roadway and shot the rear end of the vehicle up and then potentially caused an accident/death. This has happened to many I have discovered upon further research and is a common problem with the vehicle according to the dealership. Vehicle has been towed to the dealership to be inspected and/or repaired. Zero warning signals, lamps, or messages.

My car has been well maintained and always taken for service according to recommendations from the manufacturer. My brakes have ALWAYS squealed since I first bought it new but apparently there’s nothing they can do about it so I’ve just dealt with it. Now a more serious concern I am having after manufacturer warranty is my dash is displaying a shift to park message every time I shift into park and turn off my car. I also might add that this has been going on with others! Chevy doesn’t think it’s a concern when it is a very serious issue. I have children and once when I went to get gas after almost being on empty my car wouldn’t turn off because of that error and I couldn’t get gas. I tried turning it off and on multiple times to fix but it just didn’t want to work when I needed it most. I have to aggressively charge gears go get it to work most of the time. It’s a serious issue that has been brought to their attention and shouldn’t be happening to a vehicle under 50,000 miles and well maintained. These issues need to be addressed there’s no reason I should have to pay to fix an issue this extensive and costly in a 2022 vehicle.

The front exhaust assembly is leaking. There’s many reports online for the same year and vehicle about bolts rusting out. Some still under warranty (36,000 miles, ridiculous!), and some not, like mine. I have 36,800 miles, of course out of warranty. GM has a problem with these exhaust systems, and should be recalled. Thank you

The bolts attaching my muffler to my exhaust pipe sheared off of my 30,000 mile 2022 chevy trailblazer at highway speed, launching them into my muffler. My exhaust pipe dropped-at 70 miles an hour it could have ripped off, and I am lucky the bolts went into my muffler and not something more vital. Also, If the pipe or muffler had fallen, I-or someone behind me- could have run over it causing potential control issues. I am seeing that this is a common problem on various consumer forums. There was NO warning- didn't even get a check engine light after the fact- things just got REALLY loud. I was fortunate to be close to an exit (as I was in a construction zone) and was able to get a tow to the nearest dealership.
