“The engine started acting weird in traffic going down hill on freeway. Eventually turned off turning into my driveway. No warning or engine light. Towed to dealer and is in for inspection, not sure if they can repair or if they have to replace the engine. When it arrived to dealer the engine light was on with a couple misfires”
NHTSA complaint #11714080, filed 2026-01“On two separate occasions the vehicle lost all power while driving. On December 5, 2025 turning on to a main road from parking lot the vehicle shut off with no prior warning lights. Shifted vehicle to park. No power to anything, unable to unlock doors, unable to turn on hazard flashers, stuck in the middle of the road at night. Waited a minute and pressed the start button and vehicle started with no problem. Again, on February 24 , 2026 making a left turn in intersection, without any warning the vehicle shut off… no power at all. …”
