Recall campaignsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

Recall campaigns

3 campaigns cover this model year — what the defect is, what it could cause, and what the remedy is

SERVICE BRAKES, HYDRAULIC:POWER ASSIST:HYDRAULIC

Nov 28, 1994
62 units potentially affected
The defect: THE HYDRAULIC BRAKE SYSTEM ON THESE BUSES USES TWO HYDRAULIC PRESSURE SWITCHES TO OPERATE THE BRAKE LIGHTS AND THE BRAKE BOOSTER PUMP. THE BRAKE PRESSURE WARNING LIGHT CAN ACTIVATE WHEN ACTUAL SYSTEM FAILURE HAS NOT OCCURRED.
The risk: A FALSE WARNING OF THE BRAKE PRESSURE WARNING LIGHT CAN CAUSE THE DRIVER TO IGNORE A WARNING WHEN AN ACTUAL PROBLEM EXISTS WHICH COULD RESULT IN AN ACCIDENT.
The remedy: DEALERS WILL REPLACE THE TWO HYDRAULIC PRESSURE SWITCHES WITH ONE MECHANICAL SWITCH THAT IS ACTIVATED BY BRAKE PEDAL STROKE.

What a recall is

Safety recall
A safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
Safety investigation
NHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.
Manufacturer communication
Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
