Electrical System Problems of Chevrolet Traverse - part 1

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.

While driving on the freeway, the vehicle’s battery shut down. I received the following text as this happened, so there was no way I could react in a timely manner as to exercise safety and any precautions: “diagnostic alert: low 12v battery detected in your vehicle. To recharge, try and start in a well-ventilated area. If it won't turn on, try to jump start or call 1-888-4-onstar. Text stop to cancel. ” this situation was life-threatening and scary. I was scared for my life.

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 go to turn on the car on a Friday night and it won’t turn on. I got multiple failures and it said fatal errors take to dealer immediately. I brought the car to the dealer and they said the control panel needs to be replaced and they’re estimating at least a month. I’m one of four cars on a lot that need work for the same exact issue.

My 2019 chevy Traverse prior to "the storm" when I left work and approached my vehicle someone left a not in my windshield wipers stating that my horn was honking every 15 seconds it was a long shift so by the time I got to my vehicle my battery was dead. I got a jump from a CO-worker allowed my alternator to charge my battery, and it was fine (so I thought). Then the day after "the storm" happened, my Traverse went haywire displaying multiple signs of electronic failures while driving on a major highway: service esc, abs disabled, traction control disabled, power steering disabled, horn honked continuously, windows won't roll down, key fob unresponsive, manual lock/ unlock switch unresponsive, a/c on but doesn't blow cold, infotainment system on, cluster hazard light indicators on but lights aren't illuminated, windshield wipers on max speed unprompted while spraying continuously. I pulled over, placed the vehicle in "park", turned the vehicle off, safely exited to realize my vehicle was still running, got back into the vehicle where I was greeted by a prompt that said to place the vehicle in park to turn it off. I attempted to shift but it was immovable, called a tow truck. Every time after dealership visits/ repairs my vehicle shutoff while moving. It's been to the dealership 3 times (4 to include tomorrow) I've also connected an obd2 scanner to run a diagnostic after the last visit and these faults appeared almost instantly. Work done so far: x2 bcm replacements (w/ flashed software) x1 battery replacement x1 keyless entry module replacement x1 driver door lock/unlock switch replacement x3-->4 tow trucks over $3,000 in expenses.

Brakes have screeching noise transmission jumps when changing gear the shift to park is so constant can not even go out because it takes more than 20 to 30 tries for it to accept park and turn vehicle off! I have taken it to the dealer for the concern stated no recall or warranty at this point I am afraid to even leave it in shift to park and walk to the store and it gets stolen or leaves me stranded with my children.

Infotainment system broke, black screen, no ability to use back up or other cameras, or see navigation etc.

My car randomly started alerting me of “ecs service” & “brake assist service”. The dealership essentially did nothing even though there is an active recall on the 2024 models.

Special coverage programs for the 2018 chevy Traverse front exhaust pipe mounting bracket failure. Gm has focused on coverage specifically on 2019-2021 models, but 2018 models are affected as well. I'm being forced to pay for a new exhaust when 2018 models should have been included for the specific special coverage (e. G. , n212356540, n222385510) exists for 2019–2021 vehicles, offering repairs (sometimes for 15 years or 150,000 miles) when the front mounting bracket breaks.

Alternator fail before 60,000 miles. Had the car almost 3 years and children in it. Apparently a known common issue yet no recall it’s not a reliable car.

To make a very long story short, I was having major software issues with my vehicle. I had the car "blackout" lights screens and everything turn off then when it powered on I would have service lights on for my brakes. I also had my reverse camera go out a few times and my lane assistant light on dash say its not working. All to find out I had a faulty rear control module. Upon replacement I learned this exact rear control module is the same one used in other gm vehicles noted in several recalls but the part itself has never been directly recalled. So now I have the same exact part in my vehicle again which is bound to fail again at some point. My vehicle is only 3 years old and has done this with children in the car. I let gm know numerous times and they said since the part is replaced its fine. But I know this exact part is not safe. If you look up the model number on the rear control module you will see how many times it is noted in service bulletins and is main contributor to these issues. Please recall the 2023 chevy Traverse. I dont want this part just "updated" it needs redesigned.

Sometimes my backup camera will not show a screen. I have considerable amount of trouble trying to connect my phone to the car. Hands down can I use the gps on the car. Lights do not come on my dashboard. The rpm bounces up and down from starting it all the way to the while you're driving. The car does not want to stay started it does not like to go it does not hands down not like sitting still. I've either replaced or cleaned four different parts for this problem. 2017 chevy Traverse is a horrible vehicle, that doesn't like to be used. Honestly just take it back and junk it.

Our car one day showed several illuminated dash lights regarding brake system, along with several pop up warnings. We took it to a Chevrolet dealer for service. They’ve had it for 54 days. They’ve confirmed widespread brake system and electrical system failure, but even after escalating to corporate tech assistance, there is no progress nor resolution available. We were told they have at least a dozen others with this same issue. It is wildly inappropriate that there has not been a recall issued as this is a serious safety defect. We demand a buyback from gm for putting this death trap on the market knowing they had these issues with 2024 models but continuing to roll 2025 and 2026 models with the same issues.

When shutting the vehicle off, shifting to park pushing the button to shut off, the dash indicates shift to park after the vehicle is shut off. Vehicle will not lock. This is not safe to leave this way.

Vehicle: 2025 Chevrolet Traverse on [xxx] at approximately [xxx], while driving south on [xxx] , my vehicle suddenly shut off without warning resulting in a complete electrical failure. During this event, I lost the ability to accelerate, activate hazard lights, unlock doors, open or close windows, or use the onstar system. The vehicle restarted briefly but then shut off two additional times before I could safely move it off the road. There were no warning messages or signals prior to this incident. This created a serious and immediate safety hazard, as I was unable to alert other drivers or exit the vehicle during the failure. I am requesting a formal investigation into this issue, documentation as a safety defect, and immediate corrective action. This incident poses a significant risk to driver and passenger safety. The vehicle has been towed to the dealership it was purchased from. The problem has not been confirmed or reproduced by the service center. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My dashboard gave an alert “battery saver active” then another alert stating to “service charging system, vehicle may stall”. Then the alerts cleared. After a few minutes both alerts were on my dashboard again. I was able to pull into an [xxx] ’s and had them check the battery, which was replaced a few months ago, employee stated that the battery was so low, only showing 11. 4 that they couldn’t even test it, that she testing the alternator and the computer said it needed to be replaced. The employee stated that most gm replacement alternators for chevy Traverse 2023 are on back order due to so many having to be replaced right at the 3 year mark. We could only get a store brand replacement part due to the back order. Once I bought the part, my husband drove behind me for the 30 minute drive home, we had to pull over twice to jump off the battery and charge it due to the vehicle stalling. Once home we replaced the part and seems to work fine, it has only been 9 days. I have the original part for inspection and receipts of purchase for the new part. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Vehicle: 2019 Chevrolet Traverse issue: “shift to park” warning – vehicle fails to recognize it is in park I am filing a complaint regarding a persistent &dangerous defect with my 2019 Chevrolet Traverse involving the “shift to park” warning system. For the past several years, my vehicle has repeatedly failed to recognize that it is in park, even when it clearly is. This issue has escalated into a serious safety and reliability concern. Most recently, I was stranded in a store parking lot for over two hours because my vehicle would not properly shut off or restart due to the false “shift to park” warning. I had to call someone to disconnect the battery to prevent it from draining completely, which caused additional cost and inconvenience. After reconnecting the battery, the vehicle still would not start for another 2hours. This defect leaves me at risk of being stranded at any time, including in unsafe or isolated. As a single parent of 4 young children, this creates a significant safety concern for my family. This problem has been ongoing since oct 2023 and has occurred repeatedly since then, and consistently every month since then, often four or more times per month. I have brought this issue to a Chevrolet dealership, reed-lallier Chevrolet in fayetteville, nc, multiple times. Despite being charged diagnostic fees, no permanent fix has been provided. This is a known issue with this vehicle model related to a faulty shifter assembly or park detection system. This defect impacts the vehicle’s ability to shut off, restart, & function reliably, creating a serious safety hazard. I am requesting that this issue be formally investigated & that appropriate action be taken to require a recall or manufacturer-covered repair. This problem is widespread among similar vehicles & should not continue to leave drivers stranded or at risk. Mileage: 44,410 miles dates of occurrences: oct 2023-present dealer contacted: reed-lallier Chevrolet on raeford rd fayetteville nc.

Driving down the interstate the main screen went out completely, gps, radio, controls to temperature for the back. Back up camera works and it shows a chevy sign. Gm dealer states the radio/onstar module is out completely. This ironically happened immediately after warranty expired.

When car is shifted into park, it does not register that. It is in park. Therefore the car keeps beeping, and you cannot leave the car in this position. This is the second time that we have had to address this problem once in 2021 and now in 2026 I believe that general motors should fix this problem without the consumer being charged to have it corrected.

Nhtsa defect report (initial portal filing) manufacturer target: general motors (gm) filer: joseph r. Fears classification: mechanical defect & administrative evasion narrative for submission I am filing this formal defect report regarding a catastrophic, systemic safety failure present in the 2025 Chevrolet Traverse architecture (VIN: 1gnevgrs1sj123332), manufactured by general motors. The vehicle was originally purchased at autonation timonium. The safety defect and telemetry proof on March 18, 2026, the vehicle suffered a total failure of the transmission and drivetrain systems. It was immediately surrendered to preston Chevrolet, where it remained completely out of service for 34 consecutive days. Gm's own onstar diagnostic telemetry automatically dispatched critical fault alerts while the vehicle was stranded, explicitly logging the following irrefutable failure codes: dtc u1962 (pcm - engine and transmission system): warning stated: "system transferring power to the drive wheels not performing as expected. " this indicates a catastrophic decoupling or failure to transfer motive power. If this failure occurs at highway speeds, it results in a total loss of propulsion, creating an extreme rear-end collision hazard. Dtc u0452 (viu - onstar system): a simultaneous failure in the wireless communication and safety system, meaning that when the drivetrain catastrophically fails, the vehicle's automated emergency sos and crash-reporting telemetry is actively blocked or compromised. Elevation to administrative evasion general motors and its authorized dealer network were provided with formal written notice of this defect. The 30-day statutory right to cure window fully expired without any mechanical resolution. Rather than deploying engineering solutions to rectify the severe safety defects they released into the public domain, gm has instead deployed aggressive legal maneuvers designed to evade accountability.

Car cut off in the middle of driving it entire screen goes black and disable, onstar does not go off continues to blink green even when vehicle is disable, vehicle is not completely powering off after shut down causing the battery to drain overnight.

Our 2019 Traverse transmission around 130,000 miles started shuddering when slowly accelerating or driving. Not sure what causes this but I do know that it should be doing this as well as getting the shift to park message. I looked online and found that it's supposed to be the torque converter. I then contacted a transmission repair specialist and he stated that changing the fluid may make it worse or make it possibly fail altogether. Then I found a video about shudder fix and I added one of those packets to the transmission and it stopped the shudder but it now seems to be trying to creep back. This is a known issue with most people not being able to afford the $9000+ repair costs. The shift to park issue is another issue that shouldn't be happening and the dealership will charge an arm and a leg for the repairs on this as well. Pressing the gear shift button about 5 to 10 times after shifting to park is a short term solution because that issue is tied to a spring action underneath the shifter to tell the car I'm in park. I found a bypass piece that is required to resolve the issue but I shouldn't have to do that to get this vehicle to work properly. Chevy needs to do a recall on this or they run the risk of having a bunch of them on the market where we all got rid of them and won't buy anymore Chevrolet vehicles. This is the second newer model vehicle I had from them. The first one was an impala and the dealership didn't know why the screen would go black and cause the car to start hesitating horribly. So I left it with the dealership, they can have it back.

I’m reaching out for help with a frustrating situation. I purchased a brand new 2026 Chevrolet Traverse in new york, but after moving to texas, I'm having trouble registering it. The car can't pass the state inspection due to emissions issues, and local dealerships aren't providing any assistance. The only advice I've received is to drive it around for a bit, hoping the problem resolves itself. However, I'm concerned about the safety of myself and my 4 children, and it seems like Chevrolet isn't taking this issue seriously. What steps can I take to resolve this situation?.

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.

After refueling we re-entered i495 northbound. While traveling in the fast lane of traffic my vehicle shut off. I lost all power, including the ability to use on-star. The vehicle refused to start for thirty minutes. This problem repeats within a mile of refueling. The vehicle has been taken to the dealer. The first time the said it was a sensor in the stable trak. This last time they claimed a bolt on the battery was loose. There was no pre-warning the car just stopped in rush-hour traffic on the busiest highway in America.

Onstar module failed causing battery to drain and no eta on part -- from chevy - to drive the vehicle the module is disconnected by the dealer as parasitic battery drain causes all other safety systems to fail - with module disconnected hazard lights will not work - so if situation happens where hazards are necessary to save occupants life they are not working and functioning due to care to able to function.

When returning home I had trouble turning off the vehicle. I was getting error to shift to park when it was already in park. Had to cycle multiple times before it registered it was in park. Less than 60k miles but does not appear as a recall and does not appear to be under warranty.
