Example complaints
Engine: “I started experiencing excessive oil burn at around 85,000 miles. Since then, I have checked my oil biweekly to top off and keep at proper levels along with consistent oil changes as the oil gets dirty quickly. Dealerships before have told me that its normal for these engines. At 109,610 miles, I discovered a bad oil leak. I took the vehicle into an independent mechanic to diagnose and fix the problem. He determined that the vacuum pump had broken off into the engine which caused a seal problem for the top of the engine. …”
NHTSA complaint #11341888, filed 2020-07, 109,610 milesExterior lighting: “Back-up lights - visibility lighted by back-up lights is terrible. The back-up lights are very dim and directed upwards instead of back onto the pavement as they should be. The stop lights actually give more light than the back-up lights. The first month I had the vehicle I had several near misses because I could not see the vehicles in back of me. I can actually see better shining a flashlight behind me than I can to see with the back-up lights. …”
