2021 Chevrolet Trailblazer Complaints

"shift to park" issue on a 21 traiblazer causing your car to not being able to shutdown entirely meanwhile the shift is perfectly on Park.

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...

Reduced engine powers caused by turbo charger underboost, at 91200 miles.

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.
