What owners wrote
A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.
Driving around a corner when the steering locked its self in position causing the truck to not turn, almost as if when you shut the vehicle off and turn the wheel it locks in position. This caused the vehicle to leave the road and hit a tree. The driver side airbag did not deploy. The passenger side airbag did deploy.
High speed collision with a cement truck destroyed most of the front portion of the vehicle. Neither passenger nor driver airbag deployed and seat belts did not lock up, injuring the driver. No warning lights indicating an airbag problem appeared prior to crash. The vehicle is now impounded at towing company yard pending insurance investigation.
Door locks will not work they stay unlocked or locked whichever possession they are in have had repaired 3 times at dealer are gone again replaced actuator 3 time an 3 of 4 doors now driver side and back passenger side gone again. Afraid granddaughter can open door while driving.
When traveling merging on I-70 outside of london ohio my truck started making very loud exhaust sound. After inspection found that driver side and passenger side rear exhaust manifold bolts where broke off allowing unfiltered exhaust to pass. If leak would have been too bad the high temperature of the exhaust could potentially cause a fire inside the engine compartment. The exhaust also broke welds off the exhaust causing the exhaust to fall the break is where the h-pipe come together.
