NHTSA Complaint #11441920 — 2016 CHEVROLET SUBURBAN

On Friday evening, I noticed a higher revving noise when accelerating at lower speeds. The noise appeared to resolve at higher speeds. The noise continued into Saturday. After driving approximately 90 miles Saturday, while at highway speeds of 75mph, the engine stopped accelerating and began dropping speed. When pushing the gas pedal, the rpm revved up to 3-4000 immediately with no change in speed. Arriving at the destination quickly, I turned the car off. My husband got in approximately 5 minutes later, turned the car on, put it in drive, and the car immediately went backwards. This happened multiple times even though the car was in drive and the accelerator was pushed. The following morning (Sunday) after being turned off approximately 16 hours, the car cranked and drove normally through the yard about 500 feet. The car was then trailered 100 miles back home where it sits awaiting placement at the mechanic shop for diagnosis. At no point, including while driving, were there any warning signs/lights/noises to indicate the engine was failing. Thankfully children were not present in the car at the time, however this could have been a catastrophic event.
