The car has been back in the shop for the past two weeks. Auto start stop hasn't worked in two years and I was told by the dealer it's because my battery is bad. I replaced and coded it myself but the issue persisted so I was then told it's because I didn't use the OEM battery. Had the dealer replace the battery themselves and low and behold, the issue was still there. Now they replacing the mechatronics. There's a 4 week wait time for parts.
I think they also broke the oil sensor when they replaced the gaskets last time, since that started throwing errors as soon as I drove it out of the shop. CNA is covering both parts though.
- Mechatronics (transmission valve body): $8500
- Oil sensor: $800
So now we're up to $27,865 in repairs in 4 years.
I don't particularly care about auto start stop, but if I ever sell the car I don't want anyone to low ball me because it's such an expensive part to replace. I haven't decided yet if I'm going to drive it into the ground or get rid of it once the warranty runs out.
