The contact owns a 2003 Ford Ranger. While driving approximately 5 mph, the spark plug shot out of the engine and left a large hole in the engine block. The check engine light illuminated. The vehicle was coasted to the side of the road and was later towed to an independent mechanic. The technician diagnosed a spark plug blowout and stated that a repair kit was needed. The manufacturer was made aware of the failure and advised the contact to take the vehicle to a local dealer. The contact was informed that there were no recalls. The failure was not remedied. The VIN was unknown. The failure mileage was 142,000.

Carquest water pump new 18420011 (T4188) complete failure after 100 miles. A new water pump was installed onto a 2003 Ford Ranger V6 3.0 VIN-V truck. He vehicle was driven between 25 - 60 mph off and on for approximately 1 week totaling about 100 miles. Under normal driving conditions (30-35 mph) and with slight acceleration, the bearing housing sheared off from the water pump body launching the cooling fan/clutch into the radiator. Power steering failed (no drive belt) and the cooling system dumped it's contents. The body of the pump is still intact to the vehicle, but the rest of it came off. Upon inspection of an identical part from the same store, there is an apparent casting color difference on the pump. It appears that there is a casting defect present in the pump and the installed pump broke almost perfectly aligned to the casting color differentiation.

Engine stalls and won't re-start due to improper activation of the passive anti-theft system (pats) which is faulty. Engine shuts off, no power assist, lights remain functional, anti-theft dashboard light starts to blink. Vehicle will re-start only after removing and re-installing the #19 fuse to re-set the system. It may require several re-sets of thirty or more seconds each, after which the vehicle may run normally for a short distance or up to several months of normal driving. There are folks who shared their similar experiences on-line alerting me to the re-set procedure. I am told the solution to the problem requires the replacement of the power control module, which the pats is part of, and that it is not possible to otherwise disable the pats anti-theft system.
