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 1990 DODGE Monaco. Campaign records are official safety actions; applicability to a particular car still requires its VIN.

REAR BRAKE TUBE ROUTING IS CONTACTED BY FUEL TANK HEAT SHIELD WHEN SUSPENSION IS IN FULL JOUNCE POSITION. THIS DAMAGES THE BRAKE FLUID TUBE, CAUSING A LEAK.
Consequence
LOSS OF FLUID FROM HALF OF THE DIAGONALLY SPLIT BRAKEHYDRAULIC SYSTEM AFFECTS BRAKING CAPABILITY, WHICH COULD RESULT IN AN ACCIDENT.
Remedy
MODIFY HEAT SHIELD TO ELIMINATE POTENTIAL FOR SHIELD CONTACTING BRAKE TUBE.
THE END CAP CONNECTING THE HEAT EXCHANGER'S CORE TO THE ENGINE COOLING SYSTEM COULD RUPTURE AND ALLOW HOT COOLANT TO ESCAPE INTO THE PASSENGER COMPARTMENT.
Consequence
THE COOLANT ESCAPING INTO THE PASSENGER COMPARTMENT COULD CONTACT THE DRIVER'S FEET AND INJURE THE DRIVER. ALSO, STEAM FROM THE HEATER LIQUID WILL CLOUD ON THE WINDOW SURFACES AND IMPAIR THE DRIVER'S VISION. IN EITHER CASE, FAILURE OF THE HEATER CORE END CAP COULD RESULT IN A VEHICLE ACCIDENT.
Remedy
A COOLANT TEMPERATURE CONTROLLED HEATER CORE FLUID BYPASS VALVE WILL BE INSTALLED.

THE AUTOMATIC SHOULDER BELT SYSTEMS CAN MALFUNCTION AND BECOME INOPERATIVE.
Consequence
THE LACK OF PASSIVE RESTRAINTS COULD INCREASE THE RISK OF PERSONAL INJURY IN THE EVENT OF A VEHICLE COLLISION.
Remedy
DEALERS WILL REPLACE THE SYSTEM TRACK AND DRIVE ASSEMBLY ON AUTOMATIC SHOULDER BELT SYSTEMS WHICH ARE CURRENTLY INOPERATIVE AND THOSE SYSTEMS WHEN THEY BECOME INOPERATIVE IN THE FUTURE.

SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:DISC:ROTOR
VEHICLE DESCRIPTION: PASSENGER AND MULTI-PURPOSE VEHICLES ORIGINALLY SOLD OR CURRENTLY REGISTERED IN THE STATES OF CONNECTICUT, ILLINOIS, INDIANA, MAINE, MARYLAND, MASSACHUSETTS, MICHIGAN, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, OR WISCONSIN, AND THE DISTRICT OF COLUMBIA. THE FRONT DISC BRAKE ROTORS CAN EXPERIENCE SEVERE CORROSION IF OPERATED FOR AN EXTENSIVE PERIOD IN THE "SALT BELT." IF THE ROTORS ARE NOT REPLACED, THE CORROSION CAN EVENTUALLY COMPROMISE THE STRUCTURAL INTEGRITY OF THE STAMPED STEEL CENTER HUB SECTION OF THE ROTOR.
Consequence
THE REDUCED STRENGTH CAN ALLOW THE CAST IRON WEAR SURFACE TO SEPARATE FROM THE HUB, REDUCING THE BRAKE EFFECTIVENESS OF THE VEHICLE.
Remedy
DEALERS WILL REPLACE THESE ROTORS WITH ROTORS THAT ARE COATED WITH A CORROSION PROTECTION.
LOWER INTERMEDIATE STEERING SHAFT MAY SEPARATE AT THE RUBBER ISOLATED COUPLING OF THE SHAFT.
Consequence
THIS COULD RESULT IN LOSS OF STEERING CONTROL AND AN ACCIDENT.
Remedy
REPLACE INTERMEDIATE STEERING SHAFT WITH A SHAFT CONTAINING A RESTRAINED COUPLING.

Complaints across nearby Dodge Monaco 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.

The canonical URL is this file’s permanent public identifier. Source IDs and timestamps show exactly what was matched and when; they do not turn the evidence into a verdict.
Only NHTSA vPIC, NHTSA ODI complaints and investigations, NHTSA recalls and FuelEconomy.gov contribute to this vehicle claim. CPSC equipment notices are searched separately and never joined to vehicle fitment. UK MOT, Canadian, New Zealand and European records are not merged into this US claim.
06 · Research paths
Diagnose first. Confirm fitment.
These are transparent searches, not diagnoses or endorsed parts. Recall remedies come before purchases; exact part fitment requires VIN, trim, powertrain, production date and OE number.
