We were at a restaurant with friends we got back into the vehicle. I started up the vehicle and several electrical things happened. The service trailer brakes message came up, then the service power steering message came on. The engine was running but the tachometer didn-€™t work, or the oil pressure gauge. A couple other warning lights on the dash were on and stayed on. When I put it in reverse it wouldn-€™t move. When I put it in drive it would move forward. So we were stuck in our parking spot. We decided to put it in neutral and two of us pushed the truck out of the space into a busy street in hopes of getting home. Luckily none of us or the truck was hit by the people driving on the roadway. I put the transmission in drive and it would go into gear but not not shift out of first gear. The speedometer was not working either. We drove a few 100 feet in hopes that it would shift into a higher gear and it would not. We were able to find a safe place to pull off the highway and parked it. Turned the truck off, waited several minutes and tried it again. Still the same so we were stranded there. Left it there and called an Uber driver to come out and pick us all up. I called for a towing service to pick the truck up the next morning. When I arrived the following morning to meet the tow truck I got in and started it up. Other than the check engine light being on the truck seemed fine. I still had it towed to the dealership to be on the safe side. It was there 6 days and today I picked it up. They couldn-€™t find anything wrong. In the description of service and parts it states -€œscanned found long list of codes, most of codes are lost communication with engine control module, followed some tsb for possible issues, no results-€. Also, -€œcleared codes and test drove vehicle, have not been able to duplicate concern at this time-€. So I now have a vehicle that I can-€™t trust and hope our safety will not be in jeopardy in the future.

I remote started the vehicle to allow it to warm up. The rear window defroster automatically turned on. After a few minutes, I got into the vehicle and noticed a burning smell as well as smoke coming out of the square control unit on the rear sliding window. Quickly, I shut off the vehicle in case there would be a fire. After doing some research, I noticed that there have been several similar complaints. Other people have reported that they noticed rear defroster wires glowing and melting trim while other have reported smoke and subsequent shattering of the rear window. This happened about one month ago (I do not have the exact date).
