Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I was slowly backing up at a flat launch ramp to put our boat into the water. As the trailer reached the water, I pressed harder on the brake pedal. When I did that, the brake pedal went to the floor and the vehicle continued to roll backwards until the boat reached the water. Fortunately that stopped the vehicle from moving and allowed me to apply the parking brake. One of my brake lines had burst. The repair shop said the brake lines were all rusted and not in very good shape. …”
NHTSA complaint #10648287, filed 2014-10, 101,000 miles“While driving my 2003 k2500 chevy suburban, another vehicle pulled out in front of me from a side street while I was traveling about 35 MPH and I pressed the brakes very hard - hard enough to lock up at least one wheel, but avoided an accident. I continued on, but just a few seconds later, I approached an intersection, and the brake pedal went to the floor, with very little braking power. I was able to get the vehicle stopped by pumping the brakes quickly and ran slightly into the busy intersection. I pulled into a parking lot to inspect whether I had damaged something. …”
NHTSA complaint #10342314, filed 2010-07, 109,685 miles“A complete loss of brake pressure with no warning light indicator - when inspected the drivers side line had corroded almost directly under the drivers side door. This is the second time of occurrence, the first being the passenger side brake line in same location.”
NHTSA complaint #10502170, filed 2013-03, 130,000 miles“Was driving my 2003 SUBURBAN 2500 & went to stop, brake pedal went all the way to the floor & truck had trouble stopping. After looking what was the problem saw brake fluid all over the underside of truck and on ground. Brakelines have rusted through and have burst. Now need to be replaced.”
NHTSA complaint #10422710, filed 2011-08, 93,813 miles“While pulling away from the driveway, coming to a stop the brake pedal went to the floor. After getting the vehicle back in the driveway, a large amount of brake fluid was running out from a location under the drivers door area. After inspection, the brake line to the left rear wheel was rusted through and ruptured. All brake lines look totally rusted. Limited or no brakes is a big problem on a 3/4 ton vehicle. This vehicle's under carriage is washed on a very regular basis.”
