Intermittent airbag light would come on. When I took to dealership, it was always out, and instead of paying extravagant diagnostic fees they said may not show problem, I did not get it looked at. It was repaired today. . . . A harness electrical shortage which I feel should not be charged to the customer. The short is for something that only a certified tech repairs. Airbags harnesses on this vehicle per the repair tech go out regularly, which sounds like a defect to me. The repair passed on to me was more than $300! also, iac attached with too little silicone, which causes the iac to burn and malfunction. It was also repaired. I do not have parts. . . . . Dealership kept them.
The car wouldn't start so I had it towed to the dealership. The technician tried it and it started right up for him. They couldn't find anything wrong with it. I'm not sure if I have it right but I was told the reason it didn't start was I had the wrong type of fuel, winter verses summer. The temperature dropped after thunder storms during the night. There's been quite a few times when the car didn't start up on the first turn of the key but I didn't think anything of it. There was another time when it didn't want to start but eventually did. It was a rainy, snowy night. This last time when it didn't start it had rained also. I'm wondering if it has more to do with the rain and not the fuel.
The fuel gauge is not reading correctly.
