What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The vehicle experienced an immediate, dangerous loss of motive power in active traffic. The dashboard displayed an amber check engine light alongside the central master warning light (an amber triangle with an exclamation point inside).
The first time, while driving at 50-55mph, the engine decelerated suddenly. After about 10-15 seconds struggles with the gas pedal and brake pedal, the car accelerated normally. I pulled safely to side of the road to shut off the engine and start again. Things seemed to work like normal.
Water pump design failure caused a leak of coolant into vacuum lines preventing coolant from cooling engine and causing immediate overheating. Known issue previous class action lawsuit.
At first, the yellow electrical system malfunction warning light came on. After a short time of driving, the light turned red, and very shortly after than (within five minutes as I was trying to drive the vehicle to the dealership for repair), all of the electrical systems in the vehicle failed.
The virtual cockpit (dashboard) went completely black except for an exclamation point. Speed, warning symbols, engine temp etc were not visible. Dealers has confirmed the issue and is currently trying to remedy the situation. The danger was not knowing how fast I was traveling.
The vehicle was taken to the dealer. The dealer informed the contact that the speed control software needed to be reprogrammed. The software was updated. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 1,000.
