Recall - Brake Pipe Scoring

PRODUCT SAFETY RECALL
SUBJECT:
03025 - BRAKE PIPE SCORING
MODELS:
2003 CHEVROLET TRAILBLAZER
2003 GMC ENVOY
2003 OLDSMOBILE BRAVADA
CONDITION
General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 2003 model year Chevrolet TrailBlazer, GMC Envoy,
and Oldsmobile Bravada vehicles. On some of these vehicles, the front left brake pipe may have been scored during manufacturing. The brake pipe may
lose strength at the score location due to corrosion and fatigue resulting from brake fluid pressure, vibration, and temperature changes. As a result of this,
the brake pipe may eventually fracture at the score location. If the brake pipe were to fracture, brake pedal travel would be increased and front brake
performance would be reduced. In these instances, braking would be limited to that available with the remaining half system (rear brakes).
In all of the above cases, the brake light would illuminate after sufficient fluid leaked out of the system to activate the low fluid level switch in the master
cylinder reservoir. These conditions would meet the half system requirements of MVSS 135.
CORRECTION
Dealers are to inspect the front left brake pipe and replace it, if necessary.
VEHICLES INVOLVED
Involved are certain 2003 Chevrolet TrailBlazer, GMC Envoy, and Oldsmobile Bravada vehicles built within the VIN breakpoints shown.
IMPORTANT:
Dealers should confirm vehicle eligibility through GMVIS (GM Vehicle Inquiry System) or GM Access Screen (Canada only) or DCS Screen 445
(IPC only) before beginning recall repairs. [Not all vehicles within the above breakpoints may be involved.]
Involved vehicles have been identified by Vehicle Identification Number. Computer listings containing the complete Vehicle Identification Number,
customer name and address data have been prepared, and are being furnished to involved dealers with the recall bulletin. The customer name and address
data will enable dealers to follow up with customers involved in this recall. Any dealer not receiving a computer listing with the recall bulletin has no
involved vehicles currently assigned.
These dealer listings may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle
registration data for any other purpose is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this listing
to the follow-up necessary to complete this recall.
