4 of the 4 complaints, the most recent for the most-reported components, as the owners wrote them. NHTSA removes names and VINs; long reports are trimmed. CarHooq has not verified individual claims.
The rear camera on the car repeatedly does not work. The car has been to the dealership for replacement parts several times with the problem recurring. The rear camera does not work most days. In addition, the other cameras have failed repeatedly resulting in safety systems such as automatic collision sensors working and not-working randomly when driving the vehicle.
Loss of electrical power while cruising on the interstate at 65 mph. There was a series of warning messages, YELLOW colored malfunctions such as "Sport differential malfunction", "electric system malfunction". Then RED colored warning message "Electric system: Malfunction! Safely stop vehicle." At this point, engine was running but was no longer connected to the transmission, Power steering failed. All I could do was coast to the shoulder and stop. Car would not restart. Appeared to be a complete electrical failure, e.g., could not raise or lower windows.
The generator cut off and the car coasted to a stop. The generator on these vehicles is failing on almost every single one.
The last few times I've started my car, the instrument cluster takes multiple minutes before it turns on, while the yellow check engine and red warning lights flash repeatedly.

Report it to NHTSA; complaints are what trigger investigations and recalls.
