Exact make, model and year evidence from official US sources. Recall campaigns, ODI investigations, complaint allegations and EPA estimates remain separate.
A campaign may cover only certain production dates, plants or equipment. A zero result here is not safety clearance. Use NHTSA’s official VIN tool for the individual vehicle.
Exact model-level NHTSA results for 1991 MAZDA Navajo. Campaign records are official safety actions; applicability to a particular car still requires its VIN.

OPERATION OF THESE TIRES AT LOW INFLATION PRESSURES, HIGH SPEED, AND IN HOT WEATHER, CAN CONTRIBUTE TO SEPARATION OF THE TIRE TREAD.

THE STUDS WHICH ATTACH THE BRAKE MASTER CYLINDER TO THE POWER BRAKE VACUUM BOOSTER ASSEMBLY CAN DEVELOP STRESS CORROSION CRACKING AFTER BEING OPERATED FOR AN EXTENDED PERIOD OF TIME IN THE SOUTHERN CALIFORNIA LOCATION.
Consequence
IF A CRACK OCCURS, IT COULD RESULT IN ONE OR BOTH STUDS FRACTURING. THE MASTER CYLINDER COULD THEN SEPARATE FROM THE VACUUM BOOSTER, WHEN THE BRAKES ARE APPLIED, PREVENTING THE SERVICE BRAKES FROM FULLY ACTIVATING INCREASING THE RISK OF A VEHICLE ACCIDENT.
Remedy
DEALERS WILL REPLACE THE POWER BRAKE VACUUM BOOSTER ASSEMBLY.

ALL OF THESE CONDITIONS CANRESULT IN A VEHICLE ACCIDENT.
Remedy
REPAIR THE TRANSMISSION WITH A NEW PARK PAWL.

Complaints across nearby Mazda Navajo model years
Totals for the same nameplate, scaled against its highest year here. They are not adjusted for how many were sold, how old they are, how far they are driven, or how much publicity a fault received — an older or better-selling year will usually carry more reports. This shows where the reporting sits, not which year is better.
An investigation means ODI reviewed a possible safety issue for this exact model-year identity. Opening one is not a defect finding; closing one does not by itself clear a vehicle.
