Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While on cruise control when climbing a hill, a warning appears telling me that the EV has failed and that I should stop driving the vehicle. At the time the warning appears the cruise control shuts off and the car slow dramatically. All 5 times this has happened the vehicles behind me have had to slam on their brakes in order to avoid running me over. Once it was a triaxle dump truck, fully loaded, he went off the right side of the road and almost hit the guardrails to avoid the collision. The car has been tested at our dealership (Jenkins Hyundai) and they have confirmed the issue.”
