What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
I was driving slowly into my driveway to prepare for turning into my garage. The car rapidly accelerated on it’s own causing me to crash into the garage door next to the one I intended to park in. I have video from my security system.
No warning light was illuminated. The vehicle was taken to a local dealer, where it was diagnosed with a camshaft carrier reseal leak. The vehicle was not repaired due to the cost. The manufacturer was not made aware of the failure. The failure mileage was approximately 85,305.
I was inform via video message that I had an oil leak coming from the camshaft carrier reseal and requires immediate attention.
Manual transmission: Shift from 1st to 2nd can be difficult at times and can only experience partial engagement of 2nd gear causing grinding and/or popping out of gear when releasing the clutch pedal along with loss of thrust.
The contact stated that while driving at an undisclosed speed, the low oil pressure warning light illuminated. The vehicle was taken to a local dealer where the rear main seal of the engine was replaced.
In November 2023 I purchased this vehicle. The dealership was made aware of the ripples within a few days of driving the vehicle. The windshield was defective and had to be replaced. The staff at the dealership did see the ripples on the windshield and agreed to replace the windshield.
