2018 Chevrolet Traverse

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.

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.

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.

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.
