I am submitting this complaint regarding a complete transmission failure in my 2018 Chevrolet Traverse (VIN 1GNEVGKW7JJ279077). The vehicle's transmission stopped functioning altogether, resulting in a complete loss of propulsion. The vehicle can no longer be driven and requires repair/towing. A sudden loss of propulsion can create a serious safety hazard, particularly if the failure occurs while driving in traffic. My mechanic has informed me that they have experienced multiple transmission problems with 2018 Chevrolet Traverses and that issues involving this transmission are still being researched and addressed. I am concerned that my failure may be part of a larger, known problem involving GM's 9T65 9-speed automatic transmission. GM has previously issued technical service information concerning the 9T65 transmission and established a transmission replacement pilot program involving certain vehicles equipped with this transmission. GM also developed additional diagnostic and repair strategies based on transmissions returned through that program. These actions raise concerns regarding the reliability and premature failure of this transmission. I am concerned that a transmission capable of completely failing and causing loss of propulsion represents a potential safety defect that warrants investigation, regardless of whether the vehicle remains under the original factory warranty. I respectfully request that NHTSA investigate transmission failures involving 2018 Chevrolet Tr

The vehicle will not register that it is in park, when the engine is turned off a beeping noise 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 annoying. it is listed as a known problem on the forum group. when the notice to shift into Park is stuck on, the beeping will not stop... Also there is a shudder while driving no matter the speed. They did a transmission service and messed with torque converters but has not done anything. Also will be driving down the road with cruise control and the cruise control with randomly jerk and shut off for no reason. Has happened on the interstate.

Car recently started to jolt when accelerating. Noticed it firsthand on the highway while on stop and go traffic. It's been doing it more often now when driving around the city. As soon as you accelerate past 15mph, it starts to jolt. The check engine light is not on. I do see that other 2018 Chevy Traverse have a recall, but my car (when checking by VIN) is not included.

Only solution is to replace the transmission shifter assembly.

Cracked flex pipe on exhaust system

On 08/15/26, I was at a traffic light waiting to make a left turn on a major roadway. Because the wait was on a hill, the park brake automatically engaged. When the traffic light turned green and as I attempted to accelerate, the electronic parking brake failed to release as it should and normally does. Since the vehicle would not move normally, I was unable to safely make my intended left turn so I had to continue straight in order to get out of the way of moving traffic. As I was driving to a parking lot of a business in the vicinity, my back tires were screeching and smoking as the park brake appeared to remain engaged. I was extremely concerned because I was in active traffic and could not operate the vehicle normally. I attempted to resolve the problem by turning the vehicle off, allowing it to sit for a few minutes and restarting it. After at least 20 tries, I could feel the pressure of the brakes release and I was finally able to move the vehicle normally. This was frightening and placed me and other motorists at risk. I was stopped at a major intersection on a hill when the vehicle failed to operate normally as traffic began moving. Had the parking brake remained engaged, I could have been stranded in moving traffic or potentially involved in a collision. I have experienced this parking-brake problem at least seven times, including this incident, since I have owned this vehicle since 2017. I have also experienced an abnormal condition involving the vehicle in which it

Car wouldn’t move in Reverse, I’d give it gas and it would just rev. It would drive forward but very sluggish. Brought to 2 different mechanics and they both said I need to replace the transmission. Car has 97,500 miles on it. This is a known issue with these vehicles. The transmission ship had another traverse and a GMC Acadia in it for the same exact issue.

Transmission shuddering when gear changing as accelerate.

I work full time in an auto body repair shop and a fire chief. I am coming across more and more white GM vehicles where the paint is not stuck where the windshield is glued in. A couple real hard pushes and the windshield will about come completely out.

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.

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.

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.

Corrosion of the exhaust pipes lead to an exhaust leak.

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.

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.

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.

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.

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.
