On 2/17, I purchased a 2018 chevy Trax. The engine light came on 12/20/19 therefore I took it to the dealership. The diagnostics revealed two problems but only one was covered under the warranty. Problem 1. Turbo leaking at joint to inlet coupler (covered). Problem 2. Oxygen sensor defective (not covered). I have 63,676 miles on my Trax and I was told that the warranty expired at 60,800 miles on the oxygen sensor. My car is only 1,400 miles over the warranty and I am experiencing so much problems. Also at times while driving the visual screen goes blank therefore the radio and reverse camaca does not work. There was also a recall on this vehicle and the dealer took care of it free of charge. I am so disappointed about my vehicle because it is not even two years old yet and so much problems. This car must be a lemon.
