Problems with the Mazda B4000
Considering getting a pickup means more than just looking at the specs that the manufacturer states. It also means looking at the truck model's history through the years as well as the problems that previous buyers have encountered. Here are some of the issues that you need to know beyond the fact that a Mazda B4000 is a badge engineered Ford Ranger:
Size and design
Despite the fact that it weighs 3,915 pounds and that it carries a 4-liter V6 engine, the B4000's body is too small to carry heavy payloads. Still, it's the biggest of the rebadged Mazda B-series models and it could be good for those who have minimal trucking requirements and a budget that can't go for full-sized pickups.
The Mazda B4000's parts and accessories have also been criticized for their outdated design, especially since the pickup seems to have frozen during its mid-1990s heyday. Details such as the three-spoke steering wheels, tiny grille, and scalloped vents aren't as appealing to the buyers of today. However, because this model has already been discontinued, changing the look of the B4000 will have to depend on the buyer.
Older models of the B4000 will show their age because of their clumsy handling. Drivers and their passengers can experience bouncing up and down while going over rough roads. In the meantime, the steering wheel vibrates when the truck reaches 70 miles per hour or more.
Engine troubles and TSBs
The owners of truck have encountered several problems with the engine and the manufacturer itself has issued several Technical Service Bulletins (TSBs) concerning these issues. In particular, Mazda has noticed three reasons why the B4000's engine could stall. The first is that it shouldn't be running on reformulated gasoline after a cold start. Another reason could be that there's a build-up of carbon on the EGR valve seat. Finally, the engine could stall because of a sticking idle-air control valve.
Mazda has called for four recalls to certain years and model-variants of its B-Series. B4000s made in 1994 needed their manual-shift parking brakes replaced. Meanwhile vehicles from the same year with flexible holes in their front fuel lines found that the hose cracked easily. Another issue with 1994 B4000s was that the studs attaching their master cylinder to the power brake booster could also break after a long time. Vehicles manufactured on or before December 5, 2002 could also need to come into their dealerships to get a cruise control component replaced in order to prevent the switch from overheating.
