Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“In this case I left my lights on causing the battery to run down. The problem with this car is when there is no power it is impossible to open the rear sliding doors or tailgate. Only the driver's door opens with a key and you cannot open the rear doors from the inside without power. In the event of an accident that disables the power system these doors cannot be opened and passengers (especially children who are in safety seats) can be trapped. There are 3 rows of 2 bucket seats per row. I feel this car is a death trap and would seriously recommend it not be purchased.”

Additionally, the locks will fail to lock or lock with either the key or the remote fob. trapping occupants inside or prohibiting someone on the outside from getting in to retrieve children inside.”
NHTSA complaint #11434463, filed 2021-09“The headlights on this car are dangerously dim. Like the turn signals overpower them levels of dim. I’ve replaced the bulbs, the battery, cleaned all the connections, replaced the alternator, nothing makes a difference.”
