Motors Corp. Recalls Nearly 3.5 Million Pick Up Trucks, SUV's, and Suburbans
Detroit, MI (SafetyAlerts) General Motors Corp.
announced today a recall affecting nearly 3.5 million light trucks, sport utility vehicles
and vans due to defects with their anti lock brake systems (ABS).
In their talk paper, the National Highway Traffic
Safety Administration (NHTSA) said that the recall comes after one of the longest and most
costly investigations in the agency's history.
The following models were investigated
by the NHTSA:
Chevrolet Astro Vans
GMC Safaris and G-Vans
Chevrolet and GMC Suburban
Vehicles recalled as a result of this
Chevrolet Astro Vans
G series vans
Due to the complexity of the ABS systems on
these vehicles, the NHTSA said these have been two of the longest-lasting and most
resource-intensive defect investigations ever conducted by the agency.
Currently, the NHTSA has on file 10,861 reports
of brake problems on the S and T trucks equipped with EBC4 ABS units. These reports refer
to 2,111 crashes and 293 injuries. There are 2,400 reports (782 crashes and 68 injuries)
of brake problems on the Suburbans equipped with the EBC4 units. The vast majority of
these reports have not been confirmed by the agency.
GM will modify the computer program that
operates the ABS units at no charge to owners of the vehicles, NHTSA said.
GM also will conduct a service recall (referred
to by GM as a special policy") to address another potential problem identified by the
NHTSA, and confirmed by GM, during the EA94-03 8 investigation. The NHTSA discovered that
certain 1993-1996 GM light trucks equipped with EBC4 ABS units that utilize a
"three-sensor" system could experience extended stopping distances during ABS
stops on certain multiple transition surfaces; i.e., when the vehicle travels from a
pavement surface with a relatively high coefficient of friction, onto a relatively
slippery section of pavement, and then returns to the high coefficient pavement while the
ABS is still operating.
The other trucks covered by EA94-038, including
trucks equipped with four-sensor EBC4 ABS units, trucks equipped with rear-wheel
anti-lock, or RWAL, systems, and those newer trucks equipped with EBC3 10 ABS units, did
not experience this problem.
