What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Brake lines rusted through and ruptured resulting in total brake loss and a crash. The lines failed at a point directly under the driver seat. It was in motion on a city street and struck another vehicle also damaging that.
The front end of the vehicle was damaged and the air bags failed to deploy. One passenger was injured and a police report was filed. The vehicle was towed to a repair shop and they stated that the air bags should have deployed due to the impact of the crash. The failure and current mileages were 83,000.
1) brake line rusted and had to be replaced. 2) a new battery was installed only to be totally dead within 1 week 3) alternator replaced as that was thought to be the problem 4) finally found the problem and it is the abs system as the modulator / pump for this system would continually run even when the vehicle was…
Several of the exhaust manifold bolts have snapped/sheared causing exhaust leaks between the exhaust manifold and exhaust port on the cylinder head. I'm learning that this is a common issue that has gone unaddressed by the manufacturer, but is clearly an emissions and functionality issue.
The 3 rows of treads in the middle of all four tires became severely separated and worn rendering all four tires as junk causing the pickup to shake badly while going down the road. To make matters worse michelin didn't want honor any warranties, claims, etc., including the michelin plus guaranty.
I was able to use the parking brake for stopping while I maneuvered to my home. Upon inspection the next day, I found the brake line that runs along the truck frame and feeds brake fluid to the front brakes had ruptured.

I now have the exhaust ticking sound and on occasion get exhaust smell inside cab.I noticed the first broken bolt at approx 55000 miles. I now have 112000 miles.
