I purchased my dreamI bought car the end of August. The check fuel cap light came on about 3 times before I reported it. Maintenance assured me that I was the culprit. Then the check engine light came on in November. Took to shop Dec 7, replaced gas cap. Since then, it comes on about everyday. The information screen went black yesterday. Scheduled back to shop Jan 3, 2018. Wish I could get my $90,000 back and by another luxury full size sedan. I love the design and comfort but electronics spoils my experience. Great fuel economy for luxury car.
