“Throttle sticks wide open on my 1998 Mazda b2500 truck. Only recourse is to turn engine off to slow down. Have had it in to Mazda shop twice for this problem. First time under warranty, could not find the problem second time, Mazda says not covered under warranty, even though they had a TSB for this problem. I don't want to be a fatal statistic, because of yet another vehicle manufacturers failure to act.”
NHTSA complaint #10308574, filed 2010-02, 68,000 miles“I have had a head gasket replace on this 1998 Mazda b4000 within 61,000 miles. The first head gasket replacement was 1-21-2008. Now the same thing seems to be happening at 78,100 miles are there any issues with this model? I only drive the truck to work and back which is only about 5 miles from my home. Also the front end suspension makes a loud squeaking/popping noise when you turn the steering wheel or hit a rough place in pavement. The key in the ignition buzzer keeps dinging after you take the key out of the ignition.”
NHTSA complaint #10452845, filed 2012-03, 78,100 miles“B4000 truck continuously overheats. Thermostats have been replace 4 times. Truck has been worked on by certified mechanics at ford dealership. 2002 truck overheated. There was coolant in the overflow bottle but none in the radiator. Radiator leaked and head gasket was blown. I replaced radiator and heads. 2004 repeat of same incident occured.”
NHTSA complaint #10090957, filed 2004-09, 146,151 miles“The contact owns a 1998 Mazda b2500. While driving 50 MPH and attempting to decelerate, the contact must place the vehicle into neutral and then turn off the ignition. The vehicle's engine overpowers the brakes. The contact feels that this is a safety issue because the vehicle should be stopped by applying the brakes. In addition, the throttle sticks and remains open. The brake failure has been occurring for the last eight years. The vehicle has been taken to the repair shop three times regarding the failure, but no failure was identified. The failure mileage was 35,000.”
NHTSA complaint #10233085, filed 2008-07, 35,000 miles“Two incidents of engine failure within 2 miles of home. Both occurred immediately after pulling away from a traffic light or stop sign. Truck experiences wide excursions in rpms, accompanied by by check engine light on the downward swings. Within 5 to 8 seconds engine shuts down, resulting in loss of power steering, brakes, etc. Attempts to restart immediately after incident fail. Cranking of engine is normal, however no start. Both incidents result in towing, after which the truck starts normally, with no codes entered in the computer.”
