Dear Mazda Owner:

Thank you for contacting the Center for Auto Safety (CAS) about your Mazda Navajo, Tribute, MPV or B-series pickup. Mazda trucks and sport utility vehicles (SUVs) have an identity crisis - i.e., they are really Fords in disguise. The B-series is the Ford Ranger, the Navajo is the Explorer and the Tribute is the Escape. Only the MPV is a real Mazda and even then Ford owns half of Mazda which explains why the MPV has a Contour engine. Sales of Mazda trucks and vans is anemic compared to Ford. The B-series, Mazda's best seller averages about 40,000 per year compared t0 350,000 Rangers, the Navajo dropped off the charts in the mid-1990's with sales numbering in the hundreds compared to 400,000 Explorers. The MPV chugs along at 15,000 per year.

The reliability of Mazda trucks and vans are more like Ford and not as good as other Japanese manufacturers like Toyota or Honda. The bumpers on the MPV have long been a weak point with damage soaring over $5,000 in a series of 5-mph crashes. CAS has received consumer complaints on brake problems, engine and transmission failure, unintended acceleration, stalling and other defects that lead to extensive and costly repairs.

Seat belts failing to adequately restrain passengers have been the cause of serious injury in Mazdas dating back to 1977. This problem prompted the National Highway Traffic Safety Administration (NHTSA) to conduct an investigation for Takata seat belt buckles that open in crashes. The result was a recall of 360,433 Mazda models, including the 1989-91 Mazda MPV. Another NHTSA investigation which led to a recall was ABS failure in 1991-92 MPVs.

CAS has received complaints about transmission problems resulting in expensive repairs and premature replacement . Many of the complaints received involved the MPV, which has the troublesome EC-AT transmission. Complaints range from slipping and vibration to total failure. Mazda had two Special Service Programs on it's 1982-89 cars in which they replaced the EC-AT for free. However, they failed to extend them to include trucks.

You'll find more information on these and other Mazda problems below and what you can do about them plus a complaint box. Your information will help us build a strong case against Mazda on the defects we know about and help us spot new ones.

We need you to support the Center for Auto Safety in our fight for consumer rights and against poorly designed and unsafe cars.
