Dt*: the contact stated while driving 50 MPH on wet roads, the vehicle collided with a roadside bank. Both frontal air bags failed to deploy, and the safety belt failed to keep the contact secure in the seat, causing the contact to be thrown over the steering wheel and strike the windshield. The contact incurred internal abdominal injuries as well as head lacerations. There was a police report taken. The vehicle was towed back to the residence, and had not been seen by a dealer.
Brand new 3 month old goodyear p26570r17 g/y wrangle at/s owl tire exploded while driving and flattened within a matter of minutes. The belts were on fire inside, and the tire was bubbling and bursting ofrom the inside out...when police came after calling for fear of a fire, they said tire was on fire from the inside and was not drivable...waited 1 hour for tire to cool down before road service could begin to change tire...reported to goodyear and the tire place where we purchased would not give a new tire..made…
I was driving down the road and realized that my odometer was not working properly.. It was registering that I was going 120 MPH, in a 35, I knew that was wrong...all the other gauges are working well. I now recorded 120 MPH or sometimes it will record between 75 and 90. I haven't corrected it.. I'm waiting for GMC do something. Or until the inspection sticker expires
Speedometer continually goes haywire; it appears you are driving 50+ MPH when you are in park; when you actually do start moving you have no idea how fast you are going; max out at 120 MPH when you are flowing with traffic in a 70 MPH zone. Occurs intermittently with increasing frequency; I have not had an assessment of the cost associated with this repair done yet.
