Example complaints

Other or unknown: “The spare tire holder mounted on the rear bumper broke while traveling on the interstate at 70 MPH in heavy traffic. We were shocked to see how light it was made after it broke. No injuries happen but this could have easily turned out differently. We did not find our spare tire.”

NHTSA complaint #10885387, filed 2016-07, 2,000 miles

Suspension: “Only event so far, a properly inflated tire had the tread come off the casing at about 7000 miles at 60 MPH. I replaced the oem load range 'd' tires with load range 'e' tires.these oem tires at 2540# give a scant 160# safety margin. In july while doing maintenance for a 1500 mile trip I read the axle tags so I could obtain the correct seals for the hub bearings. The axles are rated 4400# each times 2 is 8800#. The gvw rating for the trailer is 10,000#. So if this 5th wheel is traveling fully loaded it is 1200# over the capacity of the installed axles. …”

NHTSA complaint #11289033, filed 2019-12, 7,000 miles

Brakes: “From the time I left the dealer lot, I never had brakes that worked properly. Increasing the output from the brake controller didn't help. The brakes would over heat and never felt that I had enough brake to stop the trailer/truck. Had the brakes checked by several rv dealers which LED to an adjust only. Recent trip caused hot brakes/wheels and brake smell. Went to a facility that specializes in rv repair and told them to tear the system apart and fix the problem. They found not enough voltage at brakes. …”
