Example complaints

Air bags: “In stop and go traffic approaching an intersection on a wet road, the can bus failed, disabling all or nearly all safety systems. At the time, numerous warning messages and lights appeared on the dash for srs, ABS, seatbelt pretensioner, etc. The engine would not turn off using the start-stop button, and the vehicle would not shift out of drive. According the dealer service center, a rear blind spot radar sensor is corroded, and caused a short in the can bus. …”

NHTSA complaint #11140621, filed 2018-10, 84,000 miles

Brakes: “Dealer reports that, in addition to the dangerous corrosion on rear subframe covered by the extended warranty program, the rear brake lines are dangerously corroded and may fail at any time. I inquired about how this is even possible as I am accustomed to vehicles with cupronickel brake lines that do not corrode. I was told they are merely enameled steel on this model and prone to premature corrosion where they are mounted to the chassis with plastic clips that wear off the enamel and allow premature corrosion and eventually catastrophic failure. …”

NHTSA complaint #11627957, filed 2024-11

Electrical system: “Started ignition, idle for about 3 mins warming up the engine. Preped to leave to current designation. Reverse, pulling out to the right I turn my steering wheel all the way to the right, car shuts off, all lights appear on the dash. Turn off and restarted. And continue to drive in reverse repeating the steering to the right... Car stalls again.... I finally make it home because I was not sure if the car was safe to drive. I parked, turned all the way to the right made a weird idle noise maybe 4x louder then standard but deeper. And boom stalls. …”

NHTSA complaint #10620788, filed 2014-08, 3,260 miles

Visibility (wipers, defrost, mirrors): “My vehicle has the distronic with lane sensing. The other day, the area of the front windshield around the cameras spontaneously began to crack in a circular manner. No other chips or dings were present. When I researched this issue online, I am finding it to be a very common issue. It appears it can happen at any time and with replacement glass as well. Mine cracked on a 95 degree f day in southern california.”
