On August 23, 2019, my vehicle incurred an engine and transmission failure reported by GMC onstar application. The symptoms of failure are repeated acceleration speed control causing speed limit violations, interference with other moving traffic, spousal trauma, and illumination of multiple display window lights in the dashboard behind steering wheel. On October 14, 2019, there was a reoccurrence of the same issue. In fact, this report is to get ahead of the problem before taking vehicle for service this morning, October 15, 2019, at sewell Buick GMC. I have service documentation and onstar email messages of failure for evidence of this report.

I purchased a 2019 GMC Terrain VIN: [xxx] on Jan 17, 2019 at rizza Buick GMC 8415 w. 159th street, tinley park il, 60487, on January 17, 2019. This was my first brand new car and I was excited. I traded in a 2014 GMC Terrain in the process, knowing I would be upside down on the loan. I had the first service done on April 23, 2019 at said dealership. At that visit I explained that I was hearing a noise on the passenger side vent even when the HVAC was not running. I was told nothing was detected and my vehicle was fine on May 24, 2019, I drove my vehicle to memphis Tennessee with my family for memorial day. On May 25, 2019 the check engine light came on, I was losing power to the engine. That same night customer service towed my vehicle to sunrise Chevrolet Buick GMC, 1800 covington pike memphis, Tennessee 38128, a nearby GMC dealership and set up a rental car in the area for me to drive. Because it was the holiday, enterprise was closed, and I had no vehicle to drive for two days. This was an inconvenience to me and my family, I had to alter my trip plans that were made back in February 2019. On May 27, 2019 I was told by [xxx] the technician at sunrise Chevrolet that air box tube was loose and not properly installed and could have been done during my service I had done April 23rd. I was assured everything was okay and I was good to go. On May 31, while traveling back home the check engine light came on again. Same message on the dash and it was raining at 3am. I was close to home and was able to make it to the dealership that I purchased it from. My vehicle has been in service since May 31, 2019 and I am just finding out that I have a part that is on national back order. I am not satisfied with my experience an I am reaching out to you to resolve this matter. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

I have a 2019 GMC terrian with 2500 miles. I was driving it and the car flashed low fuel, check transmission and check engine warning and shut down while I was as a highway speed. I was fortunately ok, however it stranded me at a spot with merging traffic, no shoulder and no power to get the vehicle out of there. The vehicle was able to start up shortly, then I had to deal with getting going again in this precarious spot.
