“On june 2, 2020, my vehicle was in the driveway and caught fire. I'm not sure how it started. I heard a loud boom and went outside and saw my truck fully engulfed in flames. I purchased the vehicle on 11/15/2019. It had only 4015 miles at the time. The vehicle was stationary. The last time it was driven was at 4:00 pm on june 2nd and at 9:58 pm it was on fire.”
NHTSA complaint #11338266, filed 2020-07, 4,015 miles“After my recall was fixed my truck locked into 4 wheel drive and I lost control of all my safety features. My lights would not work.

NHTSA complaint #11306595, filed 2020-02, 5,600 miles“While driving down road, sudden message of no oil pressure, turn off engine immediately . Was able to pull over with no power (luckily it was safe to do so at the time). Left a large puddle of oil underneath the front of the vehicle. Also, left large cloud of smoke from oil splashing on hot components underneath vehicle (exhaust, etc...) behind me. Vehicle was undriveable and had to be towed. Large oil leak was the result of a burst oil cooler line. Dealer did not show me the failed part. Unable to confirm nature of burst .”
