Electrical System Problems of Chevrolet Trailblazer - part 2

05/29/24 I took this vehicle to cronic Chevrolet in griffin, GA due to check engine light being on. Code detected purge pump it was still under warranty at that time only had 43,906 miles on had to get the purge pump replaced. Several weeks after getting it back I kept getting a shift to park message come up when trying to put it in park then started having trouble getting it to go into drive. I have had so many close calls from people almost bashing into me because my car will not go into drive and you constantly have to switch in and out of gears for it to finally go in. Its sucking the had right out due to it not shifting gears properly. The code reader detected transmission control module which I find to be faulty and understand there are serval recalls on this specific vehicle , when it started this issue it didn’t even have 50,000 miles on it!.

I first noticed an issue about a year ago when an electrical blaring noise was coming from my speakers followed by popping and crackling noises. I have taken my car into the dealership several times without resolution. Since then, I have noticed excessive humidity in the vehicle and recently found the trunk was flooded. I took the vehicle in to the dealership again, and they say the interior fabric is compromised now and the electrical sounds I was experiencing are coming from electrical damage inside the body. I have now read another review online from someone who had the exact same experience with this make and model. I believe this is a safety hazard to drivers who are unknowingly driving around for months in a vehicle that could be flooding and could cause severe damages like in my case. I have documents to support these claims, but I do not have electronic copies. If someone reaches out to me I can provide hard copies.

We own a 2022 chevy Trailblazer and we have experienced the “shift to park” issue more times than we can count. We receive the “shift to park” message on the dash screen after the car has been shifted to park and we attempt to turn the vehicle off. This problem has caused me to be late to my job on numerous occasions and late to an exam that determines my graduation at school. Many users report being able to just shift through the gears a couple times or wiggling the gear shift and it shuts off, but that is not always my case. I have, on a few occasions now, had to remove my gear shift knob and panel completely, locating the park switch and manually bending it to recognize that my car was in park. Doing this will typically subside the issue for about a week, but no longer than that. We have tried to have the dealership see the message when taking it in for other things, but it never seems to happen when they are watching. There were no other issues with this vehicle before this started happening. We purchased the vehicle in February with about 44,000 miles. This issue has instilled fear in me every time I go to shut my vehicle off never knowing if it will actually shut off or not. Dramatic or not, it has caused unwanted anxiety and too many mental breakdowns that were not needed. This needs to be addressed and fixed ASAP!.

Shift to park warning message continues to appear when already in park and trying to turn the vehicle off. Unable to exit and leave vehicle until you continually try jamming the gear into park over and over to get it to register.

While driving 65-70 mph cruise control will continuously "bog" down and act like it is wanting to cut off the whole vehicle. Transmission is starting to act like it is slipping to the point where I am going all the way to the steering wheel before it catches again. Vehicle is under 36,000 miles and should not be having transmission issues. Radio has been replaced once before but is now doing the same thing where it is not recognizing my phone, directions given to it by touch on screen, and will even completely turn off while in the middle of driving. Will freeze and then act like the screen has 'water' damage. Back up camera is not calibrated correctly. It states that I have more than enough room to make a turn but when looking into my mirrors, it is off by almost a foot and a half. I was in a car accident due to the back up camera malfunction with the difference in distance and with the screen malfunctioning. I have had the vehicle inspected by the chevy dealership multiple times and they have stated that there is nothing coming up on the code reader. The vehicle is available for inspection. My children ride in this vehicle and after the accident, I do not deem it quite safe with the malfunctioning parts. There has not been any lights coming on for the issues but the issues are there.

My 2022 Trailblazer has had a shift to park issue. It’s hazardous as I have to constantly park my car in reverse to get the “shift to park” message off my dashboard screen. My car doesn’t shut off properly with this issue. My car is only at 19,700 miles. It should not be having this issue.

“shift to park” alert. It started after the car had 29,000 miles. It would occur occasionally but on Jan 4th of this year, I had to restart and move my car 11 times in order for the alert to be cancelled and I was able to shut off my car. I have been told there is no parts available by the dealer who has my car and they don’t know when the work will be done!.

The radio screen is constantly going black or glitching, the music will silence, the back up camera will stop working. Carplay does not connect often, also glitches in and out when driving. There is little to no air or heat coming from the floor panel when feet option is pressed for climate. In order to feel heat or a/c have to be on face option.

Unable to remove key from ignition on numerous occasions. This gives a person an opportunity to steal to vehicle or even a child and get in the car and put in gear. Thus happens with both keys. When unable to remove the doors will not lock. My mechanic can not find a fix.

The brakes I’ve had issues with them making noises since I purchased my car. The rubber around the wheel wells about 6 months after I purchased my car and the shift to park just started this month September 2023. I feel my car is a piece of crap that’s falling apart.

The vehicle almost caused me to collide with another vehicle when I was trying to get into right lane it kept pushing back into left fast lane, this happened throughout the drive to and from northern California. Car got horrible gas mileage, wasn’t operating correctly at times, my radio screen scrambling, going blank, stop working, static cracking sounds coming out. Every time I started the car it would not connect to iphone by any means. Ignition button wouldn’t turn off, I had to push numerous times to turn off. There was an update for the lane departure issue, the radio issue there is no current fix as per manufacturer the service advisor informed me. I have looked up online recalls and see that there are many manufacturer correspondence for problems with this vehicle. Today there’s knocking coming from engine like there’s something wrong with lifters also burning smell inside vehicle.

Smudge on rear hatch above window, took to dlr they said maybe I did it. I was told to come back day after day and no record of these visits. When the fixed paint at their shop no paperwork. My radio screen scrambling, going blank, stop working, static sounds coming out, the ignition button wouldn’t turn off there was an update for the lane departure issue, the radio issue there is no current fix as per manufacturer the advisor informed me. Oct 3 23went dl show lt rear window, I had to n cal. Nov 3 at dlr Dec 4 told me to bring 5th fix back window but the left rear window defect they told me they order that day! so my vehicle was at the dealership for approx 2 weeks Feb 8-22 the day they called saying my car was ready to pickup I ask if the window was replaced yet etc. Ricky the advisor(nice guy)he tells me there’s nothing in the system about the window issue, he says he’ll tell his manager and call me back. He informs me the window was never ordered in Nov and they just ordered Feb 22nd. I picked my vehicle up Feb 22nd and it’s still having radio system issues, starting or stopping issues. Mar 27 window was replaced also tinted. The bubbles in the window tint again yesterday the radio system wasn’t working properly, the speakers were static, display not operating, blackout, the lane departure has me all over the road! the push start doesn’t operate correctly (will not shut off, the other day the car continued to roll backwards after I put in park. Lunges when parking in garage the fact that I have been going in for various issues and there’s no records or notes in system showing this. I reviewed docs I have found the miles in/out were same so how could someone have test driven to duplicate my concerns? Apr 23 I go in garage gas fumes filled the air, I thought it was pressure washer but I took it out and used fan to clear. Drive car come back garage a bit better, put garage for night…again 24th, 25th and today. I can’t see any leaks on garage floor.

The car will all of a sudden make a loud popping noise through the radio. It is enough to scare someone while they are driving and have a wreck. The brakes are very touchy to the point of almost giving you whiplash.

The shift to park feature on this vehicle keeps on displaying on the screen when the vehicle is in park and is trying to be turned off.

When you shift to park a message comes up and says shift topark when it is already in park. The main problem is the vehichcle will not shut off. You have to do many differant things to try to get the message to leave and then it will cut off. This has been happening now since it hit 29700 miles and does it almost everytime we drive it now. There is a serious problem here if you cant shut off the vehicle . I also noticed many other people having the same issue with the Trailblazers. This needs a recall fix.

Keeps blowing #46 headlight relay. Happens every 2-3 weeks. When this happens the low beams stop working. I have to switch to high beams to continue driving.

My 2023 Chevrolet Trailblazer is about 3 months old and it’s been making squeaky noises when I break. The squeaky sound is getting worse over time and I have an appointment scheduled with Chevrolet to get this resolved. My concern is a 2022 recall on this same vehicle due to the break system. Therefore, I am reporting this for the year or 2023 because my car is brand new and making screech noises every time I break. Also, my electric system randomly stops working. For example, my touch screen car play system pixelates and sometimes doesn’t even work. I turned off my car and the radio stayed on and the volume wasn’t going down. The car was off and the radio was still playing! after about 15 mins the radio stopped playing while the car was off. Something isn’t right with my Trailblazer, electric and breaks. Lastly, in the images you will see as my millage goes up so does the remaining fuel miles I have left. The fuel miles left are suppose to go down as I’m using the car. Therefore, something is also wrong with my electric dashboard system and fuel meter. Please consider a recall, this is dangerous.

I was driving west on i90 near belvidere IL, through a construction zone. All of sudden the vehicle stopped by its self. I had no control except for the steering. Once on the left shoulder of a four lane hwy(one way), another four lanes on the other side. There was a cement barrier blocking from the other side traffic. I smelled like burnt rubber, now I now it was the brakes. I checked under the hood did not see or smell something burning. After a few minutes the SUV was able to move. I was afraid for my life, just waiting on a vehicle to hit me.

I've had the brakes replaced because I thought they were an issue I was having with my abs. But my car will randomly lock its brakes as I'm driving, no matter what speed. I'm scared to drive it. It also almost loses all power after breaking but then speeds up on its own making it almost impossible to slow down or brake.

Transmission doesn’t have 3rd or 4th gear. Vehicle was smoking under hood. Found out after buying it it has flood damage. Mechanic said there was water in the transmission when inspected. Vehicle needs catylic converter sensor and vehicle has bad ground wire. Seller didn’t inform me of any of these issues and he said it was in good shape and very reliable.

Car randomly locks automatically by itself while car is parked and running. I have been locked out on several occasions. Locks while keys are in the ignition or if there just sitting in cup holder or wherever.

Popping sound from passenger side front speakers when releasing the brake pedal after a stop. Vehicle in drive.

When I start my car my car play will not connect. When I start my car and put my car in reverse to use the back up camera and then put in drive the back up camera will remain on. The speakers are static sometimes. The screen will not work and it will be slow or shut off completely. I have pulled over and shut off my car and opened my door to shut off screen and it remains on for a couple mins playing music even when I shut it off.

The contact owns a 2021 Chevrolet Trailblazer. The contact stated that while stopped at stop light, the vehicle shut off with the check engine warning light illuminated. Due to the failure, the vehicle was towed to a dealer and the transmission was repaired. Despite the repair, the vehicle continued to shut off without warning. One day while driving 60 mph, the vehicle shut off without warning, and the contact was stranded in the middle of the highway. The vehicle failed to restart after several attempts even with assistance from the highway patrol. Due to the failure, the vehicle was towed to the residence and remained at the residence unrepaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

Shortly after purchasing my Trailblazer in 2020 I noticed a glitch in the speakers where it would make a crackling noise (mainly when the car is off). It hasn’t been consistent when it happens, but since observing the issue I notice the issue happens most often when I close the trunk (by pressing the button on the trunk door. ) no warning lights shows when this happens. Although this doesn’t seem to be a harmful safety issue, anything electrical can result to something more serious. I plan to bring this issue up at my next oil change at the dealership.

"shortage in radio" according to Chevrolet's diagnostic. Caused black screen, no back up camera, no beeping when in reverse and coming close to another object, no sound when blinkers or hazard lights are on, no radio, no power to front charger, no ability to use front auxiliary cable.

Driving vehicle turn it off turn back on drive somewhere and turn it off and go swimming for an hour came back go to go start it and would not start I believe it's the anti-theft system as we replaced the ignition switch and the ignition cylinder but my illumination selector for my gear selector nor my tachometer works nor do my front two windows or locks.

Started having issues where all the electronics on the car go blank/dead. So far when this has happened it has not caused the car to be inoperable but in the meantime I have found that the car is leaking (seriously leaking) under the entire drivers seat was soaked. I noticed a while back that it smelled like mildew in the car, I had it cleaned and put a damp rid pouch in there, that basically absorbed in 2 days, but never could find the water. This week I found the water. . . Under the drivers seat. This car has been leaking for 2 years! last night, I get in the car and plug in my phone to charge and get a message of liquid detected charging is not available because liquid has been detected in the lightning connector. Disconnect to allow the connector to dry. At the same time the phone was plugged in everything started to crackle and squeal through the radio and then no radio at all. There is no way all these components are not damaged. Meanwhile I have take it to a dealer for them to do a "water test", I have zero confidence that this water test will yield any positive results and I am without a vehicle . So I am trying to get this info out anywhere I can to see if other people had similar issues and what can be done. It can not be safe to drive a car that the electronics have water damage.

My headlights turn off bybthemselves while driving, other times they wont turn off at all after car is turned off even while in park, and other times they turn on while switched to off position randomly in the middle of te night resulting in a dead battery come morning. My driver window no longer works as well as driver power locks. Happening since 2020 random at first now permentant removal of fuse switch in order to shut off lights and the fuse switch is hot to the touch upon removal.

Purchased my 2021 chevy Trailblazer in August 2021 with less than 100 miles. After about 500 miles the lane assist, forward collision assistant and the automatic breaking features all stopped working. Factory reset has been set several times with no fix. The buttons on the steering wheel do not do anything when pressed. I have been told by the dealership they will need to keep my car for at least 3 days to disassemble and trouble shoot the issue, however they do not have a rental to provide me in the mean time. I am now at around 10k miles because this is my daily driving and only vehicle. I am not comfortable that some of the safety features have stopped working and fear that any day something else could stop working that is more important to the functioning of the car.
