Re: Safety Defect Recall Notification filed with NHTSA
Meritor WABCO Recall Number 11E039000
Ferrara Fire Apparatus Campaign # 11V-507
Ferrara Fire Apparatus Inc. has been notified by Meritor WABCO that a defect, which relates to motor vehicle safety, exists in units with Electronic Stability Control Systems (ESC) installed. Our records indicate only 104 Inferno / Igniter chassis has received one of the suspect ESC modules. The purpose of this letter is to inform you of our plan for addressing this defect.
What the defect is and the risks involved in vehicle safety:
Meritor Wabco has determined that under certain unique road and driving conditions involving tight, successive, highly banked curves in opposite directions, vehicle body roll and road inclination characteristics may adversely affect the slip angle calculation by the ESC Module. This might cause the ESC system to perceive an oversteering situation and therefore apply the front axle outer wheel service brake until the vehicle is perceived to be stable by the ESC. This unnecessary brake intervention may pull the vehicle out of the curve, requiring the driver to counter steer to keep the vehicle on its intended path. If the driver is slow to react during this described unnecessary ESC intervention, the vehicle may deviate from its intended path. All known occurrences of this described condition have occurred on tight S-type curves that are highly banked above 6 degrees. The faster the vehicle is drives on this unique road condition, the tighter the curves and higher the bank, the more likely the occurrence of unnecessary oversteer brake activation by the ESC.
What Ferrara Fire Apparatus is doing to resolve this issue.
Once the required replacement ESC modules have been procured, a Ferrara Fire Apparatus Inc. field service technician will visit each affected location to replace the defective module and recalibrate the ESC system. Replacement ESC modules should be available to Ferrara Fire Apparatus by Meritor WABCO by November 30, 2011. Vehicles affected will be attended to as quickly as possible thereafter.
Other Manufacturers Fire apparatus will also be affected and they will be handled by their own recall campaign notifications. The Meritor Wabco ESC Module part numbers affected are:
• 446 065 020 0
• 446 065 027 0
• 400 850 179 0

NHTSA Investigates GM Truck Brakes
By Light & Medium Truck
The National Highway Traffic Safety Administration is investigating Chevrolet and GMC pickup trucks and sport-utility vehicles for possible brake failure, Bloomberg News reported.
NHTSA said it has received complaints about loss of braking effectiveness due to brake lines that rupture because of corrosion. The agency has received 110 complaints about a loss of braking effectiveness, including three crashes, involving the vehicles. In 37 of those cases, a brake line failure was confirmed by a dealer inspection, Bloomberg said.
The defect may affect 6 million Chevrolet and GMC C/K series pickups and SUVs for the 1999 through 2003 model years.
General Motors did not immediately respond to a request for comments, Bloomberg said.
