Incident Jun 23, 2026

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.

Incident Jul 3, 2026

Vehicle shudders when driving between 18mph and 40mph. Brought into dealership, was told that the Torque Converter is coming apart, and that it would require an entire Transmission replacement. This vehicle has been immaculately maintained, and only has 34745 miles on it. There is no reason that a main component of a powertrain should fail at such a low milage. I was told that the Warranty only convers the part for 5 years regardless of the low milage. Was quoted $8500 (at a discount) for the repair required to make the vehicle road worthy. Just to be clear, this is a one owner, garage kept vehicle that averaged less than 5000 miles a year, with a flawless service record. This is 100% a manufacturing issue.

Incident Jun 23, 2026

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.

Incident Jun 7, 2026

Corrosion of the exhaust pipes lead to an exhaust leak.

Incident May 1, 2026

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.

Incident Jun 13, 2026

Transmission had a shutter when we bought it from a dealership at approximately 80,000 miles and after taking it back to dealership 2 different times we were told that was just how these newer 9 speed transmissions shift. Everything was ok and there was nothing to worry about. At approximately 120,000 miles the transmission gave out. Dealership would not honor warranty. So we took it to a private repair shop, who repaired it. Then less than 2 months later, the transmission went out again. We had it towed back to the same repair shop, who kept it for 6 more months. I just got it back saturday June 13, 2026 and drove it about 100 miles out of town and transmission went out again.

Incident Oct 23, 2025

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.

Incident Jun 14, 2026

Shifter assembly- Shift to Park. The 2018 Chevrolet Traverse repeatedly shows a shift to park message when the vehicle is already in park, this causes the vehicle to not turn off. I have already had this issue fixed by a dealership previously and the issue has come back yet again.

Incident Jan 1, 2021

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.

Incident May 26, 2026

I purchase my 2018 Traverse in 2020 from day one there was a transmission problem. Took it to a Chevrolet dealer and they told me there something broken inside the transmission which it was still under warranty. A year later we notice the transmission would slip from time to time. Took it to the dealership told the service department the issue I was having with the vehicle. Just to be on the safe side I told them to do a transmission flush on the vehicle and ask the service tech to drive it to make there were any problems. Of course I was told everything was fine with the transmission. Maybe three weeks later it was still doing the same thing slipping from time to time. Now current yesterday I went to the store with no problem, went to leave the vehicle wouldn't go in reverse and barely wanting to move. I had to put the transmission into manual to get it home. The next day I was able to drive it to the dealership to see what was wrong with it. A few hours later, I received the unwanted phone call saying the transmission was done. I was told $11,000 dollars for the repair and two weeks for it to be complete. Now I am stuck in between a hard place and a rock. I am not sure if I want to take the chance on having it replaced for it to do the same thing again in the future.

Incident Jun 9, 2026

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.

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

Incident May 14, 2026

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.

Incident May 7, 2026

Purchased the car in 2022 noticed some trans slipping issues and immediately reported it to the purchasing dealer. They took the car in serviced it and said it was good shortly after that noticed the problem again. We took it to be looked at and was told "nothing was noticed". A few months later again noticed some issues took it to another dealership and was told "nothing was noticed". Driving time dropped on the vehicle 2023-2025. Once instance driving down a major highway transmission started slipping. I reached out to Chevrolet and they were less than inclined to offer help other than to say take it in for service. I explained to them that we were lucky we were not in an accident as we lost transmission while driving on a major highway. Same response. Sporadically it would happen but no major problems. Fast forward to 2026 we noticed 2 weeks ago that driving down the street it would slip. Before we could make an appointment we pulled into a parking spot and reverse dropped. Now we have a car with no reverse. Took it to be looked at a local shop near where we were and was told transmission is bad. Now it sits because it can not be driven safely. Waiting for an appointment at a Chevrolet facility.

Incident May 5, 2026

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

Incident Apr 30, 2026

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.

Incident Apr 28, 2026

Our Traverse has the transmission shudder really bad. This started at about 20k miles. Dealership made some adjustments which helped. Now that it out of warranty, this has gotten soo much worse. This needs to recalled.

Incident Dec 31, 1969

My engine light came on, so I took it the mechanic. According to the reading it says it was my purge valve, they replaced. After driving 30 miles it came back on. I took it back and they thought it was a defected part so they replaced it again. After 30 miles, it came back on. The mechanic searched online and showed me this issue was for 2019 for a recall. I contacted GM to see if there is a recall for 2018. They said no. At this time the engine lights stays on, but it gives a evap engine light. I can't pass smog due to the issue. The gas tank does not have a cap, it's open. This is how it was when I purchased the vehicle.

Incident Apr 17, 2026

Exhaust weld break similar to the 2019 Chevy traverse

Incident Mar 26, 2026

Valor Canister Purge solenoid is faulty. After filling it up with gas and start driving the vehicle begins to stutter. After a stop at an intersection the vehicle begins to stutter and shuts off.

Incident Mar 31, 2025

The contact owns a 2018 Chevrolet Traverse. The contact stated that upon parking and attempting to turn off the vehicle, the message "Shift to Park" was displayed while the gear shifter was already in park(P). The contact stated that the vehicle responded after several attempts to shift to park(P). The dealer and the manufacturer were not contacted. The vehicle was not diagnosed or repaired. The failure mileage was approximately 81,000.

Incident Mar 19, 2026

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.

Incident Mar 19, 2026

The exhaust system on my 2018 Chevrolet Traverse has failed due to cracking in the exhaust pipe and/or muffler assembly. This appears to be consistent with known issues in similar model years where exhaust pipe brackets separate and cause cracks or holes in the exhaust system. The failure has resulted in excessive exhaust noise and potential exhaust leakage. The dealership has confirmed the issue and recommended repairs costing several thousand dollars but stated my VIN is not included in the existing recall or special coverage. Yes, the vehicle and failed components are available for inspection upon request. The failure of the exhaust system creates a risk of exhaust gases, including carbon monoxide, entering the passenger cabin, which poses a serious health hazard. Additionally, a compromised exhaust system can affect vehicle performance and emissions, and in some cases may increase the risk of fire if hot exhaust gases escape in unintended areas. This issue is especially concerning because it has been identified in other model years of the same vehicle, yet my vehicle is not currently covered, despite experiencing the same failure. This creates an ongoing safety concern for myself, my passengers, and others on the road. The problem been reproduced and confirmed by a certified Chevy dealer.

Incident Feb 9, 2026

When putting the vehicle in park it doesn’t recognize it’s in park and keeps saying shift to park.

Incident Jan 9, 2026

I have had this car seat a little over a year and the chest buckle randomly stopped magnetizing. It will appear magnetized but will pop apart. This is absolutely unsafe and these seats need pulled from the consumers.

Incident Jan 1, 2026

Vehicle was driving fine in good condition and well maintenance. No warning at all and went to drive it home from a friends and it would not go in reverse at all. Towed to dealership and they said it’s a transmission issue. There is a recall on 2018 chevy traverse vehicles. My vehicle is not showing up but I do believe this could be the issue and should be considered a recall

Incident Jan 2, 2026

My car has been acting odd and shaking a lot. Was told it could be transmission since i fixed everything else it could be

Incident Nov 13, 2025

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.

Incident Feb 19, 2026

Noxious emissions fill passenger compartment while at idle, or when using remote start. Cannot drive with windows closed, or with recirculation on. Passengers feel, "sleepy". Bracket holding flex pipe fails at the same point in several different traverse vehicles. The 2018 model we have, is not covered by a recall, even though the 2019 of the same design and fail point, is. N222385510 GM is addressing this on only select models, even though the same issue is applicable to other models, and the same part numbers are the cause and or affected.

Incident Jan 1, 2026

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.

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.

Incident Feb 6, 2026

Shift to Park" Error.. even after turning the car back on.. slowly going through each gear and back down to park I'm still getting this error

Incident Feb 2, 2026

The contact owns a 2018 Chevrolet Traverse. The contact stated that while driving at 25 MPH, there were exhaust fumes entering the cabin of the vehicle. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic, and the mechanic was notified of a failure with the exhaust manifold. The local dealer was contacted and informed that there was no warranty coverage on the vehicle for the failure. The vehicle was diagnosed, and it was determined that the exhaust manifold weld needed to be re-welded. The vehicle was not repaired. The manufacturer was contacted, but no assistance was provided. The contact was referred to the NHTSA Hotline for assistance. The failure mileage was approximately 98,000.

Incident Jan 2, 2026

My 2018 Traverse has had several issues the past few years such as the electrical components in the car turning on and off randomly, a shift to park message which has been fixed twice, and the most current problem is the transmission. I was out of town 160 miles away with my family of 6 and we were about to drive home when the engine started to sound forced while I was driving. It wouldn't go past 30 mph and I had to quickly and safely get off the road and look for a mechanic. Had we already gotten on the freeway my family would have been in much more danger. After driving cautiously to 2 mechanics they referred us to a transmission service location. We had to leave the car there for several hours and came to find out that the transmission needed to be replaced and it would cost anywhere between $4,000-$9,000 depending on if they try to fix our transmission or replace it with another transmission and the cost would depend on the warranty years. We ended up getting it towed home so that our local mechanic can take a look at it. We still haven't gotten it fixed because the repair cost is so high and we can't afford it. For being a 2018 and only having 65,000 miles we should not be having transmission issues. We also took it in to our local Chevy service dealer who confirmed the transmission needs to be repaired or replaced and an accurate cost is unknown until they open it but the first estimate was $10,000. My vehicle is available for inspection upon request. I did see there was a recall for transmission issues for this make and model but it doesn't come up for my VIN. I really hope that Chevrolet can apply the recall to all VIN numbers affected because it is a very costly repair and has put my families safety at risk. It should not keep happening to others.
