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 developed a coolant leak from the water pump and thermostat housing assembly at relatively low mileage (less than 27,000 miles). The failure caused coolant loss and low coolant warning messages, requiring major repair due to the engine’s integrated “hot-V” cooling system design.
The contact received notification of NHTSA Campaign Number: 25V201000 (Electrical System). The contact scheduled an appointment with a local dealer; however, the dealer advised the contact that the USB ports needed to be repaired to complete the recall repair.
There were no warning lights illuminated. The contact received notification of NHTSA Campaign Number: 25V201000 (Electrical System); however, the part to do the recall repair was not yet available. The local dealer was contacted.
The presense and parking and lane change and rear warning lights go on. Have had the sensors changed and recalibrated. Been to dealership 3 times without a solution. Not sure if the system is functioning or not as is sporadic
The car started over heating at 39,000 miles with the warning that “coolant temperature too high, let engine run with vehicle stationary.” Took it to the dealer for repairs and they said it’s a bad thermostat and water pump which requires the entire front end to be disassembled to change.
