While the car was still under warranty, I got an error message about passenger restraint malfunction. I took to the dealer and was told that it was caused by an iPad found under driver seat. They turned off the warning. Three months later, I get the same message again. The car is now out of warranty and I was told the error is for knee airbag wire that would take 10 hours to get to and repair, if that’s the problem. The cost will be $3800. I decided to wait. Car has 53,000 miles on it. First time I took to the dealer was on December 20,2022. Malfunction light came back on April 28,2023. I couldn’t get an appointment until May 31, 2023.
