NHTSA Complaint #11549814 — 2016 GMC ACADIA

The check engine light has come on multiple times in the past 6 months. I have taken it 3 times to be repaired and finally the found out what was wrong. The first time that I brought it in, May 2023, the Bank 1 Lean Code was coming up on the diagnostic. They replaced a sensor for $300. 2 weeks later the check engine light came on again. They got the same codes and didn't know what exactly was causing it so they fixed a bunch of things which cost me $2,200. 3 months later, the check engine light came back on again. This time they're telling me the repairs cost $3,725 and it's related to this bulletin [XXX] ). This seems like a safety hazard that I should not have to pay for. My car only has 58,000 miles. I already paid $2,500 in misdiagnosed problems and now they want me to pay another $3,725. I don't have my bills to upload because they're in my glove box and my car is with the dealership.
