NHTSA Complaint #11673741 — 2016 CHEVROLET TRAX

I purchased my vehicle on January 6, 2025. Two days later, the check engine light came on. After struggling to reach anyone at the dealership, I finally got in touch on January 14, and dropped the car off on January 22 for a catalytic converter and A/C issue. On February 23, the check engine light returned with the same code. I brought the car back on March 7, and by May, the light came on again and the A/C failed for a second time. Over 1–2 weeks, I called repeatedly but was either hung up on or transferred with no resolution. On May 23, I had the car checked at an independent shop, who confirmed it was the catalytic converter again and recommended I return to the dealer. I made an appointment online and dropped the car off on May 29. I didn’t hear anything for nearly a week. When I called, the same communication issues happened. On June 3, my sister picked up the car — it was a mess, with the back seat torn apart. I was told it wasn’t the cat but a fuel pump, water pump, and quoted over $2,000. I got a second opinion on June 22. That mechanic said it did not need a fuel pump and that it was the cat — plus spark plugs, coil pack, serpentine belt — none of which had ever been mentioned before. I’ve since spent $600 on repairs that shouldn't be necessary months after purchase. Emails to the service team went unanswered until I followed up. The car also had an ongoing rotten egg smell.On June 30, I was told they’d replace the aftermarket cat with an OEM. I emailed asking about the A/C and a service history — no reply. I dropped the car off July 2 or 3, was told it’d be ready July 7, then July 8, then told the issue was actually a cracked turbocharger, not the catalytic converter. I asked if it was safe to drive — the manager said yes, but everything online said otherwise. I was told the part would arrive in 1 day and take 2 days to replace.As of July 15, the car is still not ready. Trenton told me in person the part still hasn’t even arrived and would take 5 more days
