What owners reported to NHTSA
03/24/2023, ELECTRICAL SYSTEM,EXTERIOR LIGHTING,WHEELS: Recall notices 23V138 and 23V161 for our vehicle. We have never received notice for either one of these. The repairs have never been done. When I researched our VIN number it stated to notify NHTSA if manufacturer has failed to remedy.
02/12/2024, STRUCTURE: This will be the third frameless window that needs repaired. The adhesive comes loose from the window and they swing freely. While driving down the interstate the windows have come free from adhesive. Had to pull to side of road and tape down the window until we could get it repaired.
