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.

SUMMARY: WHERE DO I START, EXCEPT EVERYONE IS SAFE. DRIVING TO DISNEY WITH THE FAMILY FOR CHRISTMAS (DAUGHTER JOINING US FROM COLLEGE) AND WE SUDDENLY HEAR A LOUD BANG FROM THE CAB; THE STARLIGHT WINDOW BLEW OUT/ OFF. WE WERE THE ONLY ONES ON THE ROAD (DOING ABOUT 50 MPH) AND NOTHING HIT US, LOOKS LIKE THE GLUE/SEAL JUST GAVE WAY! THE OTHER THING I WAS SURPRISED THERE WERE SHARP GLASS SHARDS IN THE CAMPER AND THE GLASS DID NOT SHATTER INTO SMALL SQUARES ONE TYPICALLY SEES WITH SAFETY GLASS. HONESTLY, IT COULD HAVE BEEN WORSE IF THE GLASS PANEL WOULD HAVE BLOWN INWARD IT WOULD HAVE HIT ONE OF MY DAUGHTERS; AS IT IS, THEY WERE HIT WITH SMALL SHARDS OF GLASS.*DT*DT*JB

Too few reports in this category for a page of its own — they appear in the full complaint list.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
