Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

Latest Feb 14, 2005
InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

EMBARKED ON A ROAD TRIP AT APPROXIMATELY 9:30 AM AFTER TRAVELING ABOUT 4 MILES THE ENTIRE MOTORHOME WENT INTO A VIOLENT AND SEVERE SWAYING MOTION. I SLOWED THE VEH AND PULLED TO SHOULDER OF THE ROAD, INSPECTED ALL TIRES, NOTHING APPARENT OR OBVIOUS. USED A CREEPER TO INSPECT UNDER VEH SUSPENSION UNABLE TO DETECT A PROBLEM. RESORTED TO INTERNET WITH DESCRIPTION OF INCIDENT AND DISCOVERED A POTENTIAL CAUSE. ARMED WITH INFORMATION GARNERED FROM SEVERAL WEB SITES. THE PROBLEM WAS QUICKLY DETECTED. THE LEFT REAR TRAILING ARM WAS CRACKED, COMPLETELY INTO TWO PIECES AT THE U BOLT AREA IN FRONT OF THE AXEL. I HAVE DRIVEN THIS MOTORHOME OVER 24000 MILES AND MAINTAIN IT WELL. OWNING THIS VEHICLE FOR OVER FIVE YEARS I AM SURPRISED THAT I HAVE NEVER RECEIVED A RECALL NOTICE. MY PRIOR INTERNET INQUIRIES DONE SHORTLY AFTER PURCHASE NEVER INDICATED A PROBLEM. APPARENT THIS INFORMATION IS LEFT TO THE OWNER TO FIND OUT ON THEIR OWN AT THE RISK OF PERIL TO ANYONE ON THE HIGHWAY THAT HAPPENED TO BE NEAR AN INCIDENT. *TR

WITH ONLY 14,000 MILES ON VEHICLE THE ALUMINUM RADIATOR BEGAN LEAKING WHERE THE CORE IS ATTACHED TO THE TANK. MANUFACTURE HAS SINCE REPLACED ALUMINUM WITH STEEL RADIATORS BUT WOULD NOT AGREE TO PAY FOR ANY OF THE REPLACEMENT SINCE THE WARRANTY TIME HAS EXPIRED. I HAVE TALKED TO OTHER PEOPLE WITH THE SAME TYPE OF MOTOR HOME THAT ARE HAVING LEAKS ALSO. I FEEL THIS IS A TREND AND MAYBE SHOULD BE INVESTIGATED FOR INSTALLING FAULTY RADIATORS IN THESE UNITS. RADIATORS SHOULD LAST LONGER THAN 14,000 MILES. *TR
