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 rear ended while stopped and the seat belts didnt lock causing injury to my face from hitting the steering wheel.
The contact stated that while driving at approximately 40 MPH, the vehicle had suddenly started to vibrate and shake. The contact stated that the vehicle was maintaining its lane but was lurching from left to right. No warnings illuminated.

I had no warning lights or system alerts on vehicle or Uconnect app. I stopped in the parking lot & put the Gladiator in Park, I left the ignition on. I got off truck & got a towel to clean interior.There are several spaces to vacuum.
A braking sensor failed on the Gladiator causing the ABS, 4WD, and cruise warning lights to become illuminated. The brakes then did not work properly causing an accident. The EDR report shows the ABS system was turned off as a result of the sensor.
I hit a guardrail at 70 mph on an interstate with the front right bumper and rolled the vehicle without any airbags deploying.
Second incident occurred while driving to town and a strong brake burnt smell was occurring, when I attempted to stop again brake pedal went way down again which this time I had time to regain control from hitting gas pedal and force stop, inspected brakes and front brakes were extremely hot and smoking as if brakes…
The vehicle was in motion when 4wd and abs warning light came on to indicate failure. I hit the brakes and nothing happened. The vehicle did not stop and caused an accident when I could not stop at a red light. Consumer is currently waiting on diagnosis and no repairs have been made.
