Service Brakes

AS A MINIVAN IN FRONT OF ME PUT THEIR LEFT TURN SIGNAL ON LATE, I HAD TO HIT MY BRAKES QUICKLY AND WHEN I DID MY BRAKE PEDAL WENT TO THE FLOOR AND I WAS PUMPING AIR AND HAD NO BRAKES AT ALL. I SWIRVED AROUND THE VAN AND LUCKILY I WAS ON AN INCLINED ROAD AS I WAS ABLE TO SLOW THE VEHICLE DOWN INTO A LOT AND THEN PULLED THE EMERGENCY BRAKE TO GET THE TRUCK STOPPED. MY FRONT AND BACK BRAKE LINE BLEW OUT AND MY MECHANIC SAID I WAS LUCKY THAT I WASN'T KILLED. NOW THE TRUCK IS NOT USABLE AND THE AFTER 52,000 MILES I FEEL THIS IS A SITUATION OF DEFECTIVE BRAKE LINES. *TR

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Most recent recall on file: none. Source: NHTSA Office of Defects Investigation.
