There are three main issues: as the weather got cold here in NJ, whenever the car is started in the morning, there is a strong fuel smell inside the cabin. Also there is a lot of fumes that smell gasoline. I think it is safety issue. The auto braking does not seem to operate right. I do not see any error message, but it had never tried to avoid a collision when I have tried other cars that would have normally applied the brakes in those situations. The garage door opening function does not work as soon as the ignition is turned off. This is an electrical issue in my view.
