2021 Chevrolet Trailblazer

Experiencing reduced speed, rattling noise, check engine light, power steering light on. Chevy app shows throttle control system and antilock break system error messages. Took to Chev dealership. Advised it was fuel injector (1 /4 was burned out). Had all 4 replaced ($3000). Picked up car on a Friday, vehicle was having the same issues next day Saturday. Took it back on Monday, it is now Wednesday and they’re saying it’s the turbo charger now (another $3000). Mechanic couldn’t figure out what the issue was so it took 3 days for him to now say it’s the turbo charger. I think it was the turbo charger from the get go! What’s the purpose of the diagnostics ($250)? Isn’t it to pinpointed the issue? 1st day, took him 4 hours to say it was the fuel injector. 2nd time around it took 3 days. I kept showing them and telling them it’s the throttle control system! They’re trying to rip me off! Mechanic is saying he’s been test driving it and no issues. I took a photo of my mileage before I handed them my car and it was 79,190. The mileage today says 79,191. How and where is he test driving it if it’s only been 1 mile? Reverse and forward ? They’re lying

Shift to park error. I put the car in park but it tell I get a notice to shift the car in park when it’s already in park. Beeps and continues to tell me to shift my car in park when it’s in park. Turn off the car get out and close the door and the notice and beeping continues while the car is off and in park. Been happening since I bought it.

My vehicle started flashing “shift to park” about 2 weeks ago, after being in a GM dealership for 18 days for repair. I immediately notified them my CEL was back on and what it was showing on my dashboard ( shift to park). I dropped it off on a Saturday and that same day they told me they could not figure out what was wrong with it. I texted the Service Advisor of the notification I was having and if that was the issue to which she did not do anything about. The issue is that it will stay on, and flash and can drain my battery out and it will not allow me to lock my car or it tells me that my vehicle remote is not inside to turn it off. When I called the dealership about it, they told me that the S.A. Did not mention the issue I was having and she was not concerned with it- and they would look at it but will charge me for it ( while they already had possession of my vehicle). Dealership told me they saw no code for it and it wasn’t showing up on their end when they had my car. But the day I picked it up, and put it in park it started doing the exact issue I told them about. They told me they were getting my car to “act up” and they would of clearly seen the notification on my dash and did not look into it. Insurance has not looked into it and no one seems to be able to help me and I’ve already paid $1000.00 to two different body shops to fix my car and it’s still having that issue. At current, it’s flashing “shift to park” and I can’t get it to stop and I have to keep turning my car on. It’s a huge safety issue as it’s going to drain my battery out or cause me to not be able to start my vehicle

While driving, a service warning came on that reads "Service Power Steering" - when that came on, the brakes ceased to work properly and required significant force, causing a big delay in braking. It is not safe to drive due to the limited braking. This mirrors the recall situation for other 2021 Trailblazer models with the interrupted brake sensor.

My vehicle displayed a Shift to Park message even though I was already in Park. I could not turn off the engine, I could not lock my car. I had to go back into Drive and then Park mode and wiggle the shifter multiple times to get it to recognize Park and turn off the car. This is now happening almost every time I drive the car. I did an internet search to see how to rectify the problem only to find that this exact issue has plagued GM vehicles for a decade and they still have not chosen to rectify the faulty part. There have been multiple recalls and class action lawsuits for the SHIFT TO PARK fault but not for my vehicle year YET! There are many Trailblazer owners who are experiencing this exact issue (on online forums) and GM so far is refusing to take responsibility and issue a recall to fix the issue for owners and also to stop using this faulty system in their cars. I have reached out to GM about this multiple times the past few weeks and requested they pay for diagnostic and fix the problem because it is a common and known problem with GM vehicles but they want me to pay for it myself and the repair and then they may decide to help out - unacceptable in my opinion. To be honest there needs to be a recall NOW and GM needs to be forced to change the components in all new models to stop this happening in future models going forward. This problem can cause the car battery to drain, it can cause the vehicle to roll away if it’s not recognizing it’s in Park. Thankfully that hasn’t happened to me but others have had this happen. Not being able to shut the engine off or lock my car is a problem. This is a safety issue that needs addressing. I have lots of messages and communication from General Motors which I have attempted to attach the screenshots with the photo below but get an error message on the upload page.

The contact owns a 2021 Chevrolet Trailblazer. While the contact's wife was attempting to park the vehicle, the shift to park warning light illuminated. The dealer was made aware of the failure; however, the vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The contact was informed of an undisclosed recall; however, the VIN was not under recall. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 79,000.
