Engine And Engine Cooling Problems of Chevrolet Traverse - part 1

Engine light came on. Car started shaking and making noise when shifting. Speed would not increase while driving. When shifting into park the car does not recognize that’s it’s in park and had to jiggle the gear shift. Took it to an independent mechanic and they said it’s probably the transmission. Have to take it to a transmission shop.

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.

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.

Check engine light came on and I noticed that the cooling fan would continue running for several minutes even after turning vehicle off. Had a mechanic run the diagnostics and the code came back as a thermostat/cooling issue. Although when I called to make an appointment and told him the issue and that it was a 2021 Traverse, he knew exactly what the issue was. He said that is a very common issue in all 2021 chevy/gm engines. Online research provided a couple special coverages for repairs on 7 different gm vehicles from that same time period. Of course, the Traverse is one that is not included. Seems fairly obvious this was a gm engine issue from all vehicles in the 2021-2023 timeframe. Not sure how they can only pick out 7 models, but I am hoping an update can be made to add the Traverse and any other gm models that have that same 2021 engine.

Check engine light came on after feeling hesitation while driving and roughness while stopped. Diagnostic eval was done at shop and evaporation emissions purge valve was found to be faulty and replaced. Mechanic stated after the repair that this was a problem with certain year Traverses (unsure of which at the time) and an extended warranty was added that include 10 years or 150,000 miles.

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.

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.

Corrosion of the exhaust pipes lead to an exhaust leak.

We have had multiple issues with the exhaust system and the brackets that hold the catalytic converter in place. The catalytic converters have been replaced two times in the last 3 years with them currently needing to be replaced again. This is supposed to be our family car and it is in no way reliable. Not when we have to take it in every couple thousand miles on it to have the exhaust system repaired. We have had it into the dealership multiple times to confirm the problems.

The vehicle shudders and it very slow to shift from park to drive.

This vehicle has under 90,000 miles and is only used to transport my grandchildren to and from the local elementary school. We got in the vehicle, and it would not accelerate. The vehicle is currently at the chevy dealership getting diagnosed, but the error message was for the transmission. We do not feel that this should happen on a vehicle with this low mileage and completely without any warning.

Bracket fell off of the exhaust pipe on my 2020 Chevrolet Traverse lt, which in turn cracked the exhaust pipe, making my car create this loud noise every time the car was accelerating.

I took my vehicle for an oil change to the tracy Chevrolet dealership. I was informed that they detected a leak. I returned my vehicle on 4/28/26 for an inspection. My vehicle on has 59,297 miles. I was just informed that my timing cover located at the front of the engine has a leak and possibly the oil pan. After doing research, this seems to be a common issue.

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).

Exhaust bracket broke, created a hole in pipe, which then resulted in cracked catalytic converter. Dealership and gm denied repairs due to the hole being on the "wrong pipe" but the same bracket that is covered broke resulting in the consequential damage. Check engine light came on, loud exhaust noise. Threw codes p219a, p2097, p0171. Bulletin even outlines that broken bracket/hole can cause cracks in converter, still denied. This is a known issue with the welding on this pipe/bracket, why they didn't extend the coverage to both pipes is beyond me.

There is a recall for the year, make and model for driver side airbag, also to do with transmission slipping and both of those I'm currently having issues with on my vehicle but with my VIN its not coming up for any of the recalls but I want to request a investigation on if my vehicle or any other of the same year be added to the recall.

The contact owns a 2019 Chevrolet Traverse. The contact stated that the bracket was making an abnormal rattling noise. There was a hole on the outside of the muffler. The engine light was illuminated. The local dealer was contacted, and the bracket was replaced, but the failure recurred. The manufacturer was contacted, but no additional assistance was provided. The failure mileage was approximately 95,000. The VIN was not available.

Issue documented in pip5681c.

There is a transmission recall for 2009 to 2017 Chevrolet Traverses. My Traverse has the exact same transmission and engine as the recall but for some reason gm decided not to add my VIN to the recall. My vehicle is experiencing the exact same issues recorded in the recall. I called the gm dealership who could not help. I called [xxx] directly who told me that customers can’t make any decisions like that. This is unacceptable. If there is an issue with my vehicle due to a recall, then my VIN should have been part of the recall so that I can have the issue fixed.

Exhaust weld break similar to the 2019 chevy Traverse.

The contact owns a 2022 Chevrolet Traverse. The contact stated that while driving 65 mph on the highway, the low oil warning light illuminated. A dealer was contacted. The vehicle was towed to the dealer to be diagnosed, and it was determined that the engine needed to be replaced. The vehicle was not repaired. The contact stated that the vehicle was consuming an excessive amount of oil. The manufacturer was not notified of the failure and opened a case, and stated that fifty percent of the cost of repair would be covered. The approximate failure mileage was 84,000.

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.

Failing front exhaust pipe mounting bracket. Gm has a special coverage program (n212356540) for 2019-2020 Chevrolet Traverse which covers the repair for 15 years or 150,000 miles from the original service date. The coverage is VIN specific. My vehicle has been having this issue for two years now and my VIN is not covered. This is unfair to the consumer/Chevrolet owners who's VIN's are not listed. This is an obvious ongoing problem for many Chevrolet Traverse owners, it should be an active recall on all 2018-2023 Chevrolet Traverse owners. Especially since Chevrolet/gm is aware of the problem. Most of us are paying off our vehicles because we can't afford a new one and gm is not providing assistance for some of us who at no fault of our own are having to pay for a defect they are aware of.

I am reporting a dangerous failure of the fuel supply control module in my vehicle, which caused the engine to stall and cut off during acceleration while driving in heavy, 45-60 mph traffic. While I was able to have the issue diagnosed and repaired by newman’s auto—with an invoice available—I believe this 44,000-mile vehicle experienced a premature failure. Given that this component is currently recalled on similar Chevrolet suvs and trucks, I believe this model should be included in the recall. I can be reached at [xxx] or [xxx] for further information. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

Puttering can be heard. Manifold has been replaced already. Reverberation through steering wheel and pedal can be felt when idling. Car has shuddered when driving 40+ in the past but dealership downplayed any possible issues. There is an issue with something in this vehicle whether it's the torque converter or another part up or downstream.

Both exhaust pipes before the catalytic converter are cracked and leaking at the same welded mounting bracket. One of them gm is coving under the extended warranty but the other one also needs replaced the turn off the engine warning light. It is allowing exhaust gas to leak under the car and is preventing the emissions from operating properly.

The contact owns a 2019 Chevrolet Traverse. The contact stated that while driving at 15-30 mph and shifting gears, the vehicle failed to accelerate. The vehicle began to shudder at 50-60 mph. The yellow engine warning light was illuminated. The vehicle was taken to an independent mechanic who determined the gear system needed to be replaced. The vehicle was taken to the local dealer, where it was diagnosed and determined a new gear system was needed. There was no warranty coverage. The vehicle was not repaired. The manufacturer was not notified. The approximate failure mileage was 88,000.

When my vehicle is going between 30-45 mph there is shaking happening. Torque converter feels like its locking up and then releasing.

Flex pipe for exhaust is broken at 61000 miles rattles and makes noise upon start up and acceleration. Doesnt make sense repairs for model years before and after 2020 are being repaired for free.

While driving 65mph, the vehicle’s engine shut off, a ‘reduced acceleration drive with care’ message showed up and I had to coast to the side of the freeway. Engine would not restart and dealer confirmed a piston contacted a valve and a new engine is needed.

Failed/failing hydraulic timing chain tensionors. Common issue for this engine said to be caused by poor oiling. After speaking to many shops, this is just one of the many, very common issues that occurs in this vehicle. Started on February 20th, 2026. There are no warning or check engine lights on for this issue. People who are unfamiliar with the symptoms may be driving a vehicle that may suddenly stop running without warning as there is no light illuminated on the dash. Online it states that this may be caused by not performing oil change services on time. For my particular situation, I am a preventative maintenance specialist for the past ten years. I am professionally trained and perform pm services daily. I know my Traverse has been very well maintained and serviced with premium synthetic motor oil since my ownership. And despite this, I am now having to pay a significant amount of money to have this fixed or risk the safety of myself, my family and really anyone else on the road. My vehicle is available upon request any time.

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.
