“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.”

“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.”

“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.”
