Equipment Problems of Chevrolet Traverse - part 1

While driving on vacation approximately five hours away from home with my family, I suddenly heard a loud popping sound followed immediately by increased outside wind noise coming from the panoramic moonroof. Based on the sound, I suspected the moonroof glass had shattered. Because my family was in the vehicle, I intentionally did not open the interior sunshade, as I was concerned that broken glass could fall into the cabin and seriously injure my passengers. After safely pulling over, I inspected the roof from the outside and confirmed that the panoramic moonroof glass had completely shattered. During the drive back, the shattered glass panel completely detached from the vehicle and flew off. Fortunately, it landed in the grass and did not strike another vehicle or person, which could have resulted in a serious accident or injuries. Because this occurred over the weekend, I had no immediate access to repairs. To safely transport my family the five-hour drive back home, I had to temporarily cover the opening with a trash bag and tape to protect the vehicle’s interior and reduce exposure to the elements. After returning home, I contacted the dealership, provided photographs of the damage, and explained the circumstances. I was informed that the failure would not be covered under the vehicle’s warranty and that I would be responsible for the repair costs. I am extremely concerned that the moonroof shattered without any apparent impact from road debris or object. Had the interior sunshade been open at the time, pieces of broken glass could have fallen into the passenger compartment, potentially causing serious injuries to my family, including eye injuries or cuts. Additionally, when the glass panel detached from the vehicle, it could have struck another motorist or pedestrian, creating a significant safety hazard. I believe this incident represents a serious safety concern and request that this matter be thoroughly investigated and reconsidered for warranty coverage.

Brand new car just purchased the end of March 2026. Went through car wash multiple times with no issues until one day the shark fin antenna came off and broke the plastic anchors. Now the circuit board is exposed to weather hazards. I read online multiple times this is an ongoing issue with this specific make and model and still gm declines to cover this under warranty.

The vehicle will not register that it is in park, when the engine is turned off a beeping notifcation reads "shift to park" - you have to start the engine and shut it off multiple times, or slam the shifter into place to get it register in park. This happens constantly and is starting to get old, and annoyoing.

I bought my Traverse in 2024 it’s now two year later and my entire transmission needs replaced no longer shifting between 1000& 2000rpms this is a known issue with these vehicles and there hasn’t been a recall yet. Also the button in my shift knob tells me it is not in park (shift to park) even though it’s clearly in park. Along with the transmission issue the stabilitrack warning comes on every time the car comes out of auto shut off and jumps forward. How is this safe?.

Car not registering that its in park, it sometimes takes up to 30 minutes of needing this to shut off and with hot tempatures and young children this to me is a safety hazard.

The welds that hold the catalytic converter and exhaust pipe together have pinhole leaks. The hose that connects to the exhaust system is also failing. This has been confirmed by the chevy dealership we took it too. No warning lights were triggered. We heard a rattling noise after having a prior hose replaced. One week later we were back at the same dealership. At this appointment they discovered the pinhole leaks and confirmed there are pinhole leaks while revving the engine to 1,000 rpms. We requested gm pay to fix the issue and they have refused. Our safety is at risk because no sensors were triggered and we could smell exhaust fumes in the vehicle while using the air conditioning. This is not the first issue we had with this vehicle. Prior to this the whole car died while my wife was driving it with our 2 kids in the car with her. She had no steering or braking.

2018 chevy Traverse purchased from carvana caused carbon monoxide exposure to my family in military housing. Vehicle locked itself while running in the garage (garage door open), and CO entered the home where my children were standing near the interior door. Fire dept forced entry into the vehicle and cleared the home. All family members required oxygen at the hospital; all 3 children had elevated cohb levels. Mechanic confirmed catalytic converter failure and exhaust defect. Full description: on 6/7/26, our Traverse turned on and locked itself while running in our garage (door open) as we were preparing to leave. Exhaust was blowing toward the interior door of our military home, and CO entered the house. My children were inside near that door and became exposed. We could not unlock or shut off the vehicle. Fire dept forced entry, confirmed high CO levels, and cleared the home. At the hospital, all of us required oxygen; all 3 children had elevated cohb. A mechanic later confirmed catalytic converter failure, exhaust defect, p0171, and incomplete catalyst monitor—stating this can cause ongoing CO exposure. A build verification sheet found in the glove box (not disclosed at sale) showed pre?existing issues: exhaust rattle, check engine light, and multiple mechanical reworks. Carvana refuses to assist. This vehicle is unsafe to drive or idle.

I bought a brand new 2026 chevy Traverse on may 30, 2026, and I have been experiencing chirping sounds coming from under the hood. I took it to the chevy dealership, and they informed me that it is a known issue with no current fix available. They advised me to wait for the recall. How am I expected to identify the problem if they themselves cannot articulate what it is?.

I am receiving a shift to park warning message when vehicle is in park and is turned off.

My front seat belt will not buckle at times, has happened multiple times. When I stop and go to park it will say shift to park.

While driving the stereo went off, the ac, the car stopped in middle of the road and I lost all electrical. I tried turning back on and the emergency brake light was on and the dash said "steering assist is reduced, drive with care. ” I was able to put it in neutral and get it out of the way. Battery is good fuses were all checked 350 replaced car isn’t starting or turing over, but some of the lights have turned on.

Repeated problems trying to turn off vehicle with a "shift to park" notification being displayed. It took numerous attempts each time of banging the shift lever and flicking the shift button for it finally properly turn off. Otherwise, it would continually alarm. While the milage is only 26500, it was beyond the 5 yr warranty. I was never notified of any recall notice concerning this well documented problem. There were several class action lawsuits about this known issue, but all have since been closed. Dealer replaced transmission control range selector harness and jumper for $500.

I own a 2023 Chevrolet Traverse. While driving, the vehicle suddenly began jerking very hard during acceleration and shifting. The check engine light illuminated, and the vehicle became unsafe to drive because the transmission was not operating normally. I was concerned that the vehicle could suddenly lose power or fail while driving in traffic, increasing the risk of a crash. I took the vehicle to a Chevrolet dealership for diagnosis. The dealer found the transmission fluid was burned and diagnosed transmission trouble codes p0797 and p0700, indicating an internal transmission problem. Transmission . Pdf before the failure, I experienced harsh shifting and jerking that became progressively worse until the warning light came on. The problem has been confirmed by a Chevrolet dealership. The failed transmission is available for inspection upon request. I am submitting this complaint because I believe this transmission failed prematurely at approximately 68,933 miles. I am concerned that other owners may experience the same failure, creating a serious safety risk if the transmission loses power or fails while the vehicle is in motion.

After turning the car on, engaging reverse, and then retuning back to park (driver stepped out of vehicle once in park) the vehicle reversed 60 feet on its on through a parking lot with 2 children inside of the car (disengaged from park on its own while vehicle was running). The vehicle was ultimately stopped by a tree with damage to the tailgate and rear. The gear shift selector remained in park for the entire incident. A claim was filed with gm and the Traverse was initially labeled as a “intermittent failure” in my may 2026 claim interview. Post gm inspection, the vehicle is now deemed “operational” (no repairs from gm) and being returned to my family as of July 2026.

Onstar telematic control module. Disables emergency crash capabilities. Problem confirmed by onstar and dealer that unit is bricked. Warning light on dash read; service emergency calling . See attached upload below where I wrote VIN incorrectly but correct VIN is located in upload.

Having to have the torque converter looked into, 2nd vehicle in the last 2 years with what appears to be same shifting / shuttering problem!.

I have a concern abouth the transmisson I brought my car to the shop and ther e are atleast 6 others with transmisson isusses and only kelly blue book kit states that there are 2 recall dealing with the same problem I am having.

Back in December 2025 took car in because there was a coolant leak until the car started. Alerting me that it was overheating in the middle of the freeway. I had to find a place to pull over while the car was alerting. With urgent urgent urgent alert to pull over. Took it into dealership and it turns out it had a coolant hose leak . I took the car in for an oil change today and turns out has a host leak again. The dealer did the inspection and I don’t have the part available to fix it. And this is a brand new car giving me issues. I travel far on weekend so this would be hazzard. The dealer said the water tank low because of the leak. It’s also the rear backseat window would not go thank you it’s leaking, and that’s a safety issue. Because if there’s down emergency, we can roll the window down. We also had an issue with the break pad alert system alert me. There was no brakes. It turned out to be in update issue and again I was going to travel on vacations. Those are other issues. I’ve had with the car but the maintenance issue today is at the clothes again is leaking and is a safety hazard because if I’m driving and the car and it overheats.

My car started making a sound similar to a cracked muffler but it was a very quiet sound that lasted a minute or two and went away. I thought something was loose and took to repair shop. My catalytic converter was cracked & the mechanic said it was in a place he had never seen before. Very high up. He tried to go through gm but my issue isn’t the same as any other that had been reported. My car only has 53,536 miles on it and I bought it new in October of 2019. I maintain consistent maintenance on it at the same repair shop. There is a recall on this car about emissions and possibly affecting the catalytic converter. If I do not fall into that recall so be it but maybe I am not the only person reporting this issue. I just want to have it on record in case it ever does become a recall.

While operating the vehicle, the steering column became detached, creating an immediate and severe safety hazard. Upon inspection, the column appeared to be improperly secured using hose clamps instead of proper manufacturer components.

Getting error message on and off last several weeks - "shift into park" which does not allow the ignition to be turned off!! the only way to resolve this issue is to jiggle the gear shift or restart the car, changing gears and trying again. Sometimes it works on the second or third try! frustrating!!! what is it doing to the shift assembly? have called local dealer they will diagnose and repair at my cost! in the neighborhood of $250. 00 for diagnostic, which will be applied to the total repair costs. No idea what that bill will be. General motors just advises if it needs repair save my receipts in the event of recall for reimbursement. The car only has 21,600 miles!! I have seen other complaints on line and there are videos on you tube on how to repair this issue, obviously I'm not the only one this is happening to. The gear shift boot and console have to be removed to repair. If the above actions do not work, how do you shut the ignition off??? just let the car run until it's out of gas??? not what I would classify as safe! general motors should be taking steps to rectify this problem immediately but since they have not had "enough" complaints to warrant investigating further they are sitting idly by! help!.

Wiring harness keeps getting ate up due to soybean coated wiring manufacturing.

What is causing the problem is unknown. Vehicle was at a complete stop at red light when releasing brake vehicle lunged forward hitting vehicle in front from behind so yes there has been an accident. . 2nd time was when first starting vehicle in the morning and putting vehicle in drive when brake is released vehicle lunged forward at 7 miles an hour without touching the gas pedal. Dealer claims they cannot reproduce problem. This is a safety hazard the problem does not give you warning it just lurches forward.

Having issues with transmission at 68000 miles. Shuddering and cutting out. Shift to park comes on and also replaced alternator twice already. Replaced 1st alternator at less than 20,000 miles at 2 years old.

Onstar module not working/backorder.

Issue documented in pip5681c.

Car stalled in middle of intersection. Had to get out push it out of the way turned on again after trying few times. Stalled again at stop sign won’t turn on locked out turned off car tried few more times got out pushed it out of the way tried few more times turned on again.

The exhaust bracket is broken [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Electric door lock of front passenger door does not unlock door. Plunger tries to move up when energized but stays in locked position. Door design does not include mechanical key unlock override. A first responder would need needle nose pliers to lift up the door lock stem. This failure puts any passenger at risk of delayed exit. The left rear passenger door had this failure may 2024, no prior symptoms. The driver door had this failure a few months later. Each repair costs over $700, dealer is aware of these failures. No warnings of this failure visible. No inspections made other than dealer.

The exhaust has a leak. Loud noise, rattling coming from exhaust. Smell of fumes in the cab of the vehicle. I believe there is a recall for 2018,2019,and 2021 year models for this same issue but no recall for the 2020 model.

Check engine light came on with limited acceleration vehicle, then proceeded to overheat several times having to pull over to the side of the road in very dangerous locations vehicle was brought to dealership and it was determined it was a coolant pump. It was replaced under warranty. I want it to be known that there was an issue as others I have heard our ex experiencing the same.

The vacuum pump had a catastrophic failure. This led to failure of assisted breaking, and caused brake pedal to go rock hard while driving on the roadway. Metal shards from the vacuum pump broke off, and has now entered the engine. Chevy knows this vacuum pump is flawed, but did not include my model of vehicle in the recall. Even though it uses the same part. I received a “brake assist” message on the dash about 15 seconds prior to the loss of brakes. I had my wife and two kids with me, and this jeopardized their safety. Further research on the matter states this is a known issue at gm, but for some reason my year and model were not included.

Front exhaust bracket weld failed creating a hole in the exhaust system, as covered by gm bulletin pip5681c. This resulted in a loud noise as well as exhaust leaking into the cabin since it is near the engine, right above the drivers center console.

The vehicle started throwing an error stating 'shift to park' after putting the vehicle in park. When attempting to turn the vehicle off it will not allow it, just keeping up the shift to park message on the dash. I am then unable to lock the doors. This could kill my battery as the engine eventually turns off but the lights stay on. Furthermore, leaving the vehicle unlocked and on for some time puts it at risk of being stolen. It does not happen every time I turn the vehicle off. I have tried shifting it back and forth between drive and park and sometimes that corrects the issue. I just got this vehicle about a week ago and it has not yet been diagnosed or seen as this problem just began last night. There were no other issues experienced yet. Googling it, seems to be a common issue with many Traverse owners, stating that it is typically the transmission shift control module. I do plan on following up with the dealership ASAP.
