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

STEERING

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 transmission shift control / transmission range sensor / shift interlock solenoid in my Chevrolet Trailblazer is malfunctioning. When I shift the vehicle into park, it fails to recognize the gear change and displays an error message stating, “Shift to Park.” As a result, I'm unable to shut off the engine properly, which poses both a safety risk and a serious inconvenience. I strongly urge the NHTSA to investigate this issue thoroughly and consider issuing a recall to address the defect.

I am unsure which component maybe failing, Vehicle has not been in altered in any way ,inspected yet, nor has any warning indicators. This 2021 Chevrolet Trailblazer uses a traditional key for ignition. On several occasions now, the key is becoming lodged/stuck in the ignition when attempting to shut down or turn off the engine and remove the key. Have made sure foot is on the brake, front steering tires are straight, Shifter is properly engaged in the park position, and even jiggled the key tumbler assembly. Have had to leave the stuck key in the ignition while grocery shopping, until returning home to ask my fiance for his help and assistance. When this problem happens it is not only an inconvenience, but leaving a key in the ignition to an unattended car, obviously is not good, and leaves opportunity for many not good possibilites to occur.

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.

At 44 K miles, my car started giving me a message "Shift in to park" after I stopped my car and turned off the motor. I was unable to essentially shut my engine off and leave my vehicle. I called the GMC shop, where they diagnosed it as faulty wiring. It is not under warranty, therefore I will encure the cost which is not a normal item to go out on a vehicle. Also, our 22 Trailblazer is also giving us this same message.

Upon starting vehicle it would idle for 30secs to 1 minute before shutting completely down, then would prompt to engage brake and push start/stop button to turn back on. Two different times while driving at 60+ mph the vehicle completely stalled losing power steering and brakes. Both times when the vehicle shut down it would say to push start/stop button and then place vehicle in park, engage brake to restart. When the vehicle stalled I was getting onto a highway and was about 2 seconds from being hit from behind by a semi while I was at almost a standstill while they were doing 70+. Have taken it back to the dealership both times and it died on them once but there is no solution to this issue as no codes come up.

I could turn off the engine after driving, but the key stays in the position between the engine being on and the car being off (for example when you can listen to music but your car isn’t running). The battery light came on after the issue started and so the car service place charged us to replace the battery, because they had to turn on and of the car a lot and the car had to continue to run. I took it to a car service place and they ran tests and called Chevy test support to run diagnosis tests. They can’t figure it out. They think it might be the body control module. Not sure what that is. The car only has 31,000 miles on it and this is a safety issue because what if this happens and the steering wheel locks or it becomes a rolling hazard. This would affect the driver and others. There were no lights or errors indicating a problem before this happened.

FUEL/PROPULSION SYSTEM

On [XXX] while driving on the highway my check engine light came on. The car turned off while going 60MPH on the 18 mile stretch towards Miami from Key west and luckily there were no cars around me. I checked for the code and it was P1467 for the Evap Purge Pump. I took it to a dealership in Miami and they told me it would be fine to drive that the part needed to be replaced. I drove back to key west and bought the replacement part. That same part did not work. I checked to see if the part was receiving voltage and it was. So i will continue with going to the dealership. My wife and son have developed a cough from having to constantly smell the fumes due to their existing asthma. I will never buy another chevy again.

Engine power reduced came on after I was driving from a patient’s home. My car started driving very rough. I had to pull over because I was in danger of being hit from behind. I took my car to a mechanic and was diagnosed with the code DTC P2714. I looked online and there are a lot of people having this issue and being put in dangerous situations when we drive. Chevy knows about the issue and has not issued any recalls. Unfortunately for me my vehicle is past the limited warranty so now I have to save up money to get my transmission serviced. I’m never buying American again. I could’ve been really hurt when my engine cut off.

On 2/21/25 when I turn on vehicle the engine light came on. I checked for the code and it was P1467 for the Evap Purge Pump. I checked for the gas pump cover and didn't see anything damaged and closed it tight but engine light still on. I feel the gas or engine smell is also coming through the inside of car when fan is turned on and not safe health wise.

FORWARD COLLISION AVOIDANCE: WARNINGS

A loud popping noise heard through the radio when light pressure applied to brakes. Noise loud enough to scare the hell out of all the occupants in the car. Brakes squeaked when car was in reverse. Tried to slow down on wet pavement. Car started to veer to the right. Forward collision warning nor automatic emergency braking worked. Pushed brake all the way to the floor and the car did not slow. Rear ended another car. No airbags deployed. My passenger was okay. I got diagnosed with a concussion. Do not know if the occupants in the other car were injured.

ENGINE

On numerous occasions (typically when needing to accelerate into the flow of traffic), the Reduced Engine Power message and engine light came on, the car rapidly decelerated to 35 mph, and would not accelerate rapidly. Turbocharger, waste gate actuator, and other parts need replaced and reprogrammed, but issue persists. On one occasion, power was reduced and car was stuck "revving" at 25 mph. I have had to swerve off the road to avoid a crash of being rear-ended. Issue started around 60,000 but has happened at least 5 separate times.

IN January my fuel gage stopped working , unable to know how much gas I had. The fuel pump and floater needed to be replaced If fuel was not getting to the engine the vehicle would stop working causing a possible accident with other drivers . I did not use this vehicle for many days until a mechanic cleared for useage . It cost me $320.00 of my own money to fix this for safety concerns. As of today 1/22/25 I has been fixed by A-Plus in North Fort Myers.

STRUCTURE:BODY

Found standing water in spare tire well. Back seat constantly wet, growing mold. The whole back area is moldy, mold under driver seat. My back passenger door seal has mold and water. Seat belts in back, MOLD. I had to wear a mask just to drive to the store. The mold turning black the day I took it to a shop for a water test. It's been two days and I still haven't heard anything about the water test.
