“Car fails to accelerate past 25 mph when entering roadway. Roadway area is 45mph and vehicle would not accelerate to reach safe levels. This out myself and occupants of my vehicle in danger as traffic is already at the 45+ mph limit. Vehicle has 30,000 miles. Engine light came on after incident.”

NHTSA complaint #11745068, filed 2026-06

“Throughout the year, the car had many issues, the blind spot sensors and glass sensors didn't work, and it constantly showed that the stop/start system wasn't working. Twice, the car turned off by itself at a stoplight. Since everything is controlled through the car's large monitor, including the navigation, air conditioning, and all other functions, the monitor frequently shut off and it was necessary to turn it off and on again, or wait until the next day for it to work again. The scariest incident happened during a heavy rainstorm. …”
