2000-2003 Mazda Mpv models have a coolant seepage from rear heater pipe which can cause severe engine failure and traffic hazard due to non-drivable vehicle. Mazda Mpv 2002 was found to have a coolant leak in rear heater pipes and was taken to Mazda repair center. Mazda advised a vehicle should not be run without coolant since it can damage the engine, and replaced the lines for a cost of $1000 (parts + labor). Mpv was driven 18 miles after completed repair, then the engine suffered a complete failure in traffic and vehicle stopped in the middle of an intersection, posing a danger to Mpv passengers as well as other vehicles. Mazda repair center claims the engine failure is due to driving with low/no coolant prior to repair. Regardless, if the engine failure was due to a failed repair or due to the reason Mazda states, this is a known product defect by Mazda that should be issued as a recall notice to all affected Mpv owners. Mazda has issued a technical service bulletin (us bulletin 07-002/05) stating that warranty repair is approved only if the vehicle exhibits coolant leakage and the vehicle is within the extended 7-year warranty from vehicle in-service date. .
