Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

NHTSA ID 11723502 · filed Mar 11, 2026

It is dead everyday and I have to jump it I noticed when I attach a power source it makes very odd noises. I feel the current recall you have on the g80 2020 may be the issue. It runs extremely hot wit no warning lights showing. I have had a lot of brake dust and the car is hot fast. Also issues with usb and when connected to phone it sound like crackling and volume sounds odd unless I unplug and replug. Replaced battery twice in a year

The vehicle has 11,000 miles on it. I just drove from Boston, MA to Scranton, PA on Thursday 6/24/21. There were no issues and I did not hit any pot holes. On Friday morning we started driving and 3-4 miles away going about 40 mph, we noticed a problem on the right front. I pulled over and we noticed the tire was flat. I called triple A and took the car to a tire repair shop. The sidewall was worn all around the perimeter of the tire and it had a hole in the sidewall. I also noticed a bubble on the left front tire, thus both tires were replaced. I notified Continental and opened a claim with them.
