NHTSA complaint #11756401 — an unverified report by a vehicle owner.
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.

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
NHTSA complaint #11751446 — an unverified report by a vehicle owner.
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.

The infotainment system which controls the radio,backup camera, onstart,and other safety components stopped working i took it to a gm certified dealership and it has just been all bad from there. gm has horrible customer service and so does the gm certified shop in michigan city i took my truck in that I only had for 11 months because the infotainment center went of paid for two diagnostic tests they still couldn't] find the issue and now they they're changing me 1,037.76 for a radio which they dont even know if it's going to fix the problem which if it doesn't then I have to pay more money for another diagnostic test and more parts and because I got mad and said I'm paying for a guessing game the dealership told gm that because I had some aftermarket equipment in my vehicle that that caused the issue bullshit the stuff never got plugged into anything at that point the day of my appointment with the audio shop the screen went black with no sound they're all full of shit and didn't want to take responsibility for the widely known issue with the telemedic system

The shift to park is defective on mine and many other GM vehicles. I had it previously repaired under manufacturer warranty and then again in just over 16,000 miles driven which fell outside of the manufacturer warranty. I had to pay out of pocket for the repairs and GM refused to reimburse me for the repairs. GM has a service bulletin recognizing the defective part and still refused reimbursement. The shift to park causes the vehicle to not recognize the vehicle is in park preventing it from shutting off. This causes the battery to drain and need replacement as well. I have now had the shift to park and battery replaced twice in under 45,000 miles. The service advisor for Seminole Chevrolet advised this part should last minimum of 100,000 miles and it is a known issue. This causes a major safety concern as the vehicle doesn't shut off and could cause someone to be stranded anywhere. It is concerning that a major vehicle manufacturer is continuing to manufacture and use known defective parts. My vehicle has been inspected and repaired both times at Seminole Chevrolet in Sanford, FL. I have also contacted the Executive Resolution team at GM with no resolution. The shift to park and low battery illuminates on the dashboard before the vehicle completely shuts down due to the battery failing caused by the shift to park defect.

Shift assembly kit, it is available. Dealership has to order part for inspection. Still passed inspection. Possible unintended rollaway accidents. Not being able to lock the vehicle as well. Yes, it’s been confirmed. There’s also so many class action lawsuits against GM about this matter. Why isn’t there a recall already?! Getting the “shift to park” message in my vehicle for the 2nd time now in less than 4 years. The shift assembly kit was replaced back in December 2022. Apparently it needs to be replaced again because of a switch.
NHTSA complaint #11747213 — an unverified report by a vehicle owner.
My first complaint is that headlights, low beam, would not work. Only high beams worked. The issue stopped, unexplainable, on its own, has not occurred again. The 2nd complaint is the radio volume would 'slip' as if there were a loose wire to the speakers, and loss of sound became more frequent and for longer periods of time, eventually all sound stopped, it has not been fixed, as of yet. 3rd complaint, a brand new battery, in under a year of use, went completely dead, without any visible explanation. When an attempt to jump start the vehicle the cables from another cars battery were touched at my cars battery, it sparked, indicating to the person performing the task, there is a 'short' somewhere in the wiring system. I drive this vehicle less than 3000 miles per year, and use it sporadically with my second vehicle to keep the batteries active. I cannot explain why these issues are occurring but thought it important to mention them to other possible victims with the same issues.

The two components that failed were the water pump and the coolant control valve which caused the engine to overheat, resulting in me having to pull over along the side of a busy highway putting me at risk for injury while the vehicle cooled down. It would be available for inspection upon request. This was dangerous mostly to myself due to having to pull over on the side of a busy highway and wait until the vehicle could be somewhat ok to be driven the rest of the way home. I had to drive very slowly home with my hazards on at a very low speed. Vehicle was brought to a nearby Chevy dealership the following morning. They had the vehicle for two days and claimed they could not get the problem to present itself, however, within five minutes of me driving it off the lot it overheated resulting in having to pull over again on a busy highway. An independent service center had the vehicle and diagnosed it initially as an intermittently failing water pump. This repair did not resolve the issue 100% as the vehicle began to slowly overheat again within 18 minutes of highway speed driving. Car was towed back to repair shop from my place of employment. They were able to get it to present the issue and diagnosed it as the coolant control valve. This has so far appeared to resolve the overheating issue. The vehicle has not been inspected by the manufacturer, police or insurance rep/others. The only warning that came up was on the info screen above the steering column advising me the engine was overheating and was in idle. Immediately upon seeing this I pulled over to prevent any damage. Temp gauge was all the way in the red. Fan was blowing hard. This has never happened previously and there were no other warning lights of any kind on the dash to indicate an issue. This incident happened on 6/2. Please be advised, this vehicle has since been repaired and has ran me $2300 as it is out of warranty.

When putting the vehicle in park and turning off, a warning message will appear that states "Shift to Park" and initially a nudge of the gear shift would clear the message, after one week, a simple nudge does not clear the message. The vehicle will not turn off and continues to beep, you have to put vehicle in gear (D or R) move a few feet, return to P, press very firmly on the brake and press the ignition button, this may or may not clear the message and it could take a few attempts of these steps to clear.

I used the jack for the first time of buying the vehicle new. I jacked the vehicle up to put the spare on and the scissor jack folded up and the car dropped. So I looked up if there was a recall on it and there isn't but there is on other vehicles. Note: the car was on level hard surface ground and I placed the jack in the correct location.

After the car is parked and engine completely turned off, there is a 'Shift to Park' warning and it kept on blinking and wouldn't turn off. It drains the car battery.

I needed to have my muffler welded in November to pass inspection. I was told I would likely need the entire thing replaced in a year. I now hear another exhaust leak, and I’m preparing for a hefty car travel and have to deal with trying to get it fixed in 10 days time. This is ridiculous on a 5 year old car that I have only had two year. This needs to be a recall, insane to have to pay for a whole replacement.
NHTSA complaint #11738187 — an unverified report by a vehicle owner.
Intermittently I will receive a dashboard message reading “shift to park” after I park the vehicle and do shift to park. This is a known issue with this vehicle across several years identified as “a known issue caused by a faulty switch in the shifter assembly failing to detect when the car is in Park”. GM has identified and found a solution to this problem by replacing the entire shifter assembly at the owners own cost. This malfunction has the potential to cause great harm. Potentially the vehicle could roll if the engine/system does not identify that it is in park. This could cause very expensive damages or even take a life. The vehicle also remains in accessory mode which drains the battery and can become even more costly for the owner at no fault of their own.

Rear back up camera. One day it started to glitch when put in reverse. I placed the car in park, gave it a moment and put it in reverse again. This was repeated in the attempt to get the back up camera to work. Next- turned the vehicle off for a moment, restarted it, put in reverse and this did not help. Also, I attempted to check for update/update and reset the infotainment system. This did not help. The backup camera, after this incident has not worked since. I bought this car brand new. Also, just to note, the car shakes dramatically when increasing certain speed during winter, due to very little snow on the tires.
