Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I have severe frame rust to the point where the frame has a crack halfway around it near the rear suspension. The factory mounted tow hitch literally broke completely off of the frame due to the amount of rust that was built up around the welds while I was towing my camper, luckily I had just made it home from a trip from camping when this occurred. …”
NHTSA complaint #10456746, filed 2012-04, 180,000 miles“I purchased this truck a few months ago. Within a week I had a co worker point out the bed was leaning toward the cab. A few weeks later we got under the truck to find out what was going on. We noticed alot of rust. I looked on line to see how to fix it and found alot of people were dealing with the same issue. I decided to get some sheet metal and weld it to the frame. I then asked my boss who owns a welder if he could help me with it. He said there wasn't anything left to weld to. Then the truck started not going into park. …”
NHTSA complaint #11114941, filed 2018-07, 66,030 miles“Frame cross member behind the cab is rusted through. I have owned vehicles in salt states and not had the frame rust out. This should not be considered a wear item . This can lead to a failure whereby the fuel tank falls down leading to a high risk of fire. This was found during a replacement of the brake line (3rd set) assembly and removal of the truck bed.”
NHTSA complaint #10918981, filed 2016-10, 172,000 miles“Brake lines rusted , ABS failure ,gas lines rusted, trans cooling lines rusted. These were all failures that needed replacement through the years I have owned it. Now frame rusted and cracked . Truck basically shot .”
NHTSA complaint #10945232, filed 2017-01, 60,000 miles“'99 Gmc sierra rust issues. On both sides, the cab corners and kicker panels are have rotted away. Wheel wells are just as bad. This is not a freak occurrence. I have seen the same make and year of trucks in many states with the same issue.”
