Typical electrical symptoms owners report
- Front passenger seat heaters overheat and ignite, burning through the seat fabric and nearby clothing, sometimes filling the cabin with smoke while driving.
- Infotainment and cluster systems lose function without warning, with radio, Bluetooth, GPS, and maintenance display going dark and the vehicle sometimes failing to restart.
- Some owners report unintended acceleration during low-speed parking maneuvers, in at least one case leading to a crash.
- Headlight lenses show internal coating that melts and runs, giving the housing a discolored, aged look; this pattern lines up with the LED daytime running light recall.
- Power window switches and other electrical accessories intermittently stop responding, sometimes alongside other electrical faults on the same drive.
- Entertainment systems get stuck on and cannot be fully powered down, forcing owners to mute or lower volume as a workaround.
