This vehicle has major suspension issues containing the complete strut assembly, lower control arms, and strut yokes/forks, which can not be replaced due to the discontinuance of the vehicle and parts itself. Because of this the car cannot receive an alignment which cause the tires to be eaten up at a rapid rate. When going over a bump in the highway the steering column goes one way while the car goes another. The car slides all over the road. Extreme safety concerns for my family and I.

The air bag warning light in the dash came on intermittently during driving. I took the vehicle to the dealer for service December 27, 2023, since it was a safety issue that the authorized dealer needs to take care of. At first, they said it was a bad battery and the safety system needed reprogramming. Which they did for about $800. When driving home from the dealer the air bag light came back on so a few days later I returned the car to the dealer. Then they said it was the passenger seat safety module that needed to be replaced. That was back in January of 2024, over 6 months ago. At that point I learned that the car is not drivable since the air bag could deploy at any time or would not …
