Recently I have experienced the traction control light and thus slowing the vehicle down until I depress the gas pedal. Now, this only happens when the vehicle is above 80 mph and I never know when it will occur. The dealership says it cannot test drive a vehicle above the speed limit, so I'm basically stuck here and having to live with it. When I run the diagnostic test on the car, it says no issues. Is or has anyone else experienced this? My G70 is a 2019 Prestige model.
