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 2004 VOLVO S40. Campaign records are official safety actions; applicability to a particular car still requires its VIN.
VOLVO IS RECALLING CERTAIN VEHICLES EQUIPPED WITH GARMIN 760 PORTABLE GLOBAL POSITIONING SYSTEM (GPS) UNITS BECAUSE THE BATTERIES ON THOSE UNITS MAY OVERHEAT.
Consequence
AN OVERHEATED BATTERY COULD LEAD TO A FIRE.
Remedy
VOLVO ADVISES OWNERS TO PLEASE STOP USING THE GARMIN PORTABLE GPS DEVICE IMMEDIATELY, AND VISIT THE GARMIN WEBSITE TO DETERMINE IF THEIR UNIT IS AFFECTED. THE UNIT'S BATTERY WILL BE REPLACED WITH A NEW BATTERY AND A SPACER WILL BE INSERTED ON TOP OF THE BATTERY NEXT TO THE PCB. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL BEGAN ON NOVEMBER 18, 2010. OWNERS MAY CONTACT GARMIN AT 866-957-1981 OR VISIT GARMIN'S WEBSITE AT WWW.GARMIN.COM/NUVIBATTERYPCBRECALL.
ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH T5 TURBO ENGINES, THE POLYAMIDE TUBE IN THE FUEL LINE IS SENSITIVE TO THE EXTREME TEMPERATURES THAT MAY OCCUR IN THE AREA WHERE THE TURBO/EXHAUST MANIFOLD IS LOCATED.
Consequence
THIS MAY POTENTIALLY RESULT IN FUEL LINE LEAKAGE. FUEL LEAKAGE, IN THE PRESENCE OF AN IGNITION SOURCE, COULD RESULT IN A FIRE.
Remedy
DEALERS WILL CHANGE THE FUEL LINE MATERIAL TO TEFLON FREE OF CHARGE. THE RECALL BEGAN ON JUNE 5, 2006. OWNERS MAY CONTACT VOLVO CARS AT 1-800-458-1552.
ON CERTAIN VEHICLES SOLD IN OR CURRENTLY REGISTERED IN THE STATES OF CONNECTICUT, DELAWARE, ILLINOIS, INDIANA, IOWA, MAINE, MARYLAND, MASSACHUSETTS, MICHIGAN, MINNESOTA, MISSOURI, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, WEST VIRGINIA, WISCONSIN, AND THE DISTRICT OF COLUMBIA, REOCCURRING, LONG-TERM EXPOSURE TO CERTAIN ENVIRONMENTAL CONDITIONS SUCH AS SALTY-WET CONDITIONS, IT IS POSSIBLE FOR THE PUMP ELECTRONIC MODULE (PEM) TO BECOME CORRODED INTERNALLY. THIS CAN CAUSE A FAULTY SIGNAL TO THE FUEL PUMP, RESULTING IN LOW OR NO FUEL PRESSURE TO THE ENGINE.
Consequence
IF THIS OCCURS, THE CHECK ENGINE LIGHT MAY ILLUMINATE. IN SOME CASES, THE VEHICLE MAY FAIL TO START OR MAY STALL, INCREASING THE RISK OF A CRASH.
Remedy
DEALERS WILL REPLACE THE PEM AND INSTALL IT IN A NEW LOCATION TO PREVENT CORROSION. THE RECALL BEGAN ON FEBRUARY 20, 2008. OWNERS MAY CONTACT VOLVO AT 1-800-458-1552.
ON CERTAIN PASSENGER VEHICLES, THE NON-RETURN VALVE MAY CRACK DUE TO A POOR WELD CAUSING A VACUUM LEAK.
Consequence
IF THIS OCCURS, MORE BRAKE PEDAL FORCE MAY BE REQUIRED TO STOP THE VEHICLE AND/OR MAY EXPERIENCE A ROUGH ENGINE IDLE, WHICH COULD RESULT IN A CRASH.
Remedy
DEALERS WILL INSPECT, AND IF NECESSARY, REPLACE THE VACUUM HOSE. THE RECALL BEGAN ON NOVEMBER 29, 2004. OWNERS SHOULD CONTACT VOLVO CARS AT 1-800-458-1552.
CERTAIN PASSENGER CARS FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 225, "CHILD RESTRAINT ANCHORAGE SYSTEMS." THE SECOND ISOFIX GUIDE WAS NOT INSTALLED IN THESE VEHICLES AND, IN CERTAIN CASES, THE OWNER'S MANUAL ISOFIX INFORMATION IS INCORRECT.
Consequence
THIS DOES NOT MEET THE REQUIREMENTS OF THE STANDARD.
Remedy
OWNERS WILL RECEIVE A LETTER/PACKAGE CONSISTING OF THE SECOND ISOFIX GUIDE WITH INSTALLATION INSTRUCTIONS, AND IN CERTAIN CASES, THE CORRECTED OWNER'S MANUAL MAY BE PROVIDED. IF THE OWNER WANTS TO TAKE THEIR VEHICLE TO A VOLVO DEALER FOR INSTALLATION OF THE GUIDE, IT WILL BE PERFORMED AT NO CHARGE TO THE OWNER. OWNER NOTIFICATION BEGAN ON DECEMBER 19, 2003. OWNERS SHOULD CONTACT VOLVO AT 1-800-458-1552.

Complaints across nearby Volvo S40 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.

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.

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.
