I was driving my car and it showed no signs of any issue but the engine light came on and started blinking so I pulled over and got it towed to a mechanic. He told me that I would need a new engine that would cost me $8000. I looked into it and found that there was a defect with my vehicles engine and that if I took it to a dealership, I could possibly get it covered 100% so I did that and then they covered it and when I got the vehicle back, it had an issue every time I drove it where it was kind of speeding up and jerking when I drove it, I took it back after I told them what happened and then they told me that my catalytic converter was bad and needed to be replaced. I ended up paying $1500 to get that replaced and when I got the car back again it’s still jerking and doing the same exact thing even worse. I contacted them. They told me to bring it back which I did and they told me that it needed a software update that was not available so that I would just have to be patient. They told me that anytime I wanted to drive it I had to let it warm up for 5 to 10 minutes and that it wouldn’t do that. I’ve had my vehicle back for over two weeks and it doesn’t matter if I warm it up or not it’s still doing the same thing. I do not feel safe driving this vehicle and I have not been giving any resolution by either the dealership or by the consumer affairs case manager that I have been working with on this. This has been an ongoing issue for three months now. It’s costed me hundreds of dollars in Ubers because I don’t feel it’s safe to drive.

I believe it is a clock spring failure. The airbag light is on & the buttons on the steering wheel do not work. I searched it & have seen several posts of others having same issue. I really feel this should be looked into, cause this is highly unsafe to be driving around with what very well could be an airbag that doesn't deploy & could seriously hurt drivers. Also, the contact stated the vehicle uses 5 quarts of oil within a 2 week period.

MY ISSUE - When making turns at night with the low beam headlights on automatic and switching on the left turn signal the headlights go out for up to 30 seconds then come back on. this is very dangerous when driving in rural or low light areas.

If I have my headlights on or on auto and I use the left signal, the headlights turn off. Only the left, not the right. The display on my dash displays the lights going to off and back to auto or on when the signal has been activated and then stopped
