What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2009 Volvo Vnm, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

From owner reports, verbatim
MY OTHER ISSUE WITH THIS TRUCK IS. THE EMISSIONS SYSTEM IS NOT SAFE TO OPERATE. IF THE TRUCK'S COMPUTER CANNOT DETECT IF THERE IS A PLUGGED DPF/DOC FILTER ON THE EXHAUST SYSTEM THE DRIVER CANNOT MANUALLY ACTUATE A REGEN CYCLE. THE ENGINE'S EXHAUST STREAM STAYS PLUGGED AND CAN LEAD TO VERY DANGEROUS EXHAUST BLOCKAGE UNDER THE CAB OF THE VEHICLE AS WELL AS CAN PRESENT A DANGER TO THE OPERATOR. VOLVO TRUCKS NEEDS TO OFFER A SOFTWARE UPDATE THAT ALLOWS DRIVERS TO FORCE A REGENERATION CYCLE REGARDLESS OF "ATS STATUS" SO IF THE DRIVER KNOWS THERE IS A FAULT. THEY CAN DO A MANUAL REGENERATION TO CLEAR THE DPF MUFFLER OF SOOT AND CONTINUE ON DRIVING.
MY VOLVO VNM TRACTOR TRUCK HAS AN OIL PRESSURE SENSOR FAULT. I WAS NEARLY REAR ENDED GOING DOWN THE HIGHWAY AT 60MPH BECAUSE THE TRUCK' COMPUTER DECIDED IT NEED TO STOP THE TRUCK IN THE MIDDLE OF THE ROAD. THE TRUCK'S COMPUTER GOES INTO "LIMP MODE". THE TRUCK SHUTS OFF FUEL AND DOES NOT ALLOW THE DRIVER TO SAFELY TRAVEL DOWN THE ROAD. ANY SENSOR FAULT SHOULD NOT TELL THE TRUCK'S COMPUTER TO RANDOMLY TURN THE TRUCK OFF AND CUT FUEL. ESPECIALLY IF A PERSON IS AN UNSAFE SITUATION. I'VE OWNED OLDER SEMI TRUCKS AND IF THERE WAS A PROBLEM. I COULD STILL "LIMP" THE TRUCK TO THE SIDE OF THE ROAD. EVEN WITH THE SOUND OF METAL. THE FACT OF THE MATER IS. A SEMI TRUCK REQUIRE AIR PRESSURE TO OPERATE AIR BRAKES AND EVEN WITH A TRUCK MOTOR CLATTERING, THE AIR COMPRESSOR CAN STILL GENERATE ENOUGH AIR UNTIL THE DRIVE CAN SAFELY DRIVE THEMSELF FROM THE CENTER OF THE ROAD AND CALL FOR HELP. WITH THIS VOLVO TRUCK. ONE CANNOT DO SO. THIS IS A SAFETY LIABILITY AND VOLVO NEEDS TO HAVE A RECALL ON THIS PROBLEM. SO DRIVERS CAN HAVE "LIMP MODE" REMOVED. THE TRUCK HAS ADEQUATE OIL PRESSURE AND IS IN CORRECT OPERATING RANGE AND PRESSURE.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
