The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 42
Against the median year of the International Prostar. 50 means typical for this
model; 100 means roughly double.
Severity — 0
0% of these complaints
involved a crash, fire, injury or death, against a national rate of

When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

NHTSA investigations into the 2012 International Prostar
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.

Accelerator Pedal Fails to Return
The Office of Defects Investigations (ODI) opened Preliminary Evaluation (PE15-013) on 2012-2013 model year (MY) Navistar Prostar vehicles for throttle pedals failing to return to the idle position after being depressed.EWR field reports supplied by Navistar describe the non-returning throttle pedals as preventing the engine brake from activating and elevated engine speed making it difficult to stop the vehicle.ODI contacted complainants who alleged the accelerator pedal didn?t return to the idle position.Some drivers indicated they were annoyed, while others stated that at idle they were able...

Recalls on the 2012 International Prostar
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.
Canada — Transport Canada
Canada runs its own recall programme, and its campaigns do not
always mirror the American ones.
Recall 20232931,764 units in Canada
Lights And Instruments
Issue: On certain trucks, the backup lamps could be blocked and may not be visible. As a result, the trucks don't meet the requirements of the Canadian regulations. Note: This recall only affects trucks equipped with a pintle hook lowering bracket and feature code 01WPN, 01 WPS, or 01VAL. Safety Risk: Backup lamps that aren't visible could cause a person not to recognize that the vehicle is backing and increase the risk of a crash. Corrective Actions: Navistar will notify owners by mail and instruct you to take your truck to a dealership to install new tail stop/turn signal lamps with integrated backup lamps.
Recall 2015434188 units in Canada
Structure
On certain vehicles, the fifth wheel locking mechanisms could be susceptible to damage and/or wear. This could cause the locking mechanism to fail properly engage, potentially resulting in a towed trailer unit separating from the truck tractor. As a result, the trailer could strike another vehicle, stationary object, or bystander, causing injury and/or damage to property. Correction: Fontaine dealers will replace all Ultra LT fifth wheel units with Ultra NT model fifth wheel units.
Recall 20151718,552 units in Canada
Electrical
On certain vehicles, a double battery (24 volt) jump start or electrical load dump could result in an overvoltage condition of the linear power module (LPM) which is used to control the heater/air conditioning blower motor speed. If this were to occur, this overvoltage condition could lead to the LPM overheating, causing smoke, and increase the risk of fire, which could result in injury and/or damage to property. Correction: Dealers will replace the LPM with an upgraded design.
Recall 20144841,424 units in Canada
Heater And Defroster
On certain vehicles equipped with a no-idle heating, ventilation and air conditioning (HVAC) module, the electrical harness supplying power to the module may not be of sufficient size, which could cause a voltage drop in the harness and an increase in resistance and heating at the connector. This could cause a fire, potentially resulting in injury and/or damage to property. Correction: Dealers will install a revised harness.
Recall 201404964 units in Canada
Brakes
On certain vehicles, brake s-cam bracket assemblies on the steering axle could fracture, causing an inoperative brake on the affected wheel end. This could cause the vehicle to pull to one side while braking and/or increase stopping distances, increasing the risk of a crash causing injury and/or damage to property. Correction: Dealers will affect repairs.
Recall 2013314185 units in Canada
Accessories
On certain trucks equipped with the electronic fifth wheel jaw release system, incorrect air line routing could allow the fifth wheel jaw to release without driver input. This could result in a trailer separating from the truck, resulting in a possible hazard to other road users and increasing the risk of a crash causing injury and/or property damage. Correction: Dealers will inspect air line routing and correct if necessary.
Recall 20131223,991 units in Canada
Structure
On certain trucks, the sunshade (an exterior visor mounted above the windshield) may not have been fastened to the cab roof correctly during the manufacturing process. A sunshade separating from the vehicle could strike another vehicle, a stationary object, or a bystander, causing property damage and/or personal injury. Correction: Dealers will inspect and, if necessary, secure the sunshade mounts.
Recall 20123911,156 units in Canada
Brakes
On certain trucks, the steer axle S-cam tube bracket assemblies may crack between the wing bracket and the tube steel when mounted to stamped spiders. This could result in partial loss of brake function, which could cause the vehicle to pull to one side or increase stopping distance. These issues could result in a crash causing property damage and/or personal injury. Correction: Dealers will install replacement S-cam tube bracket assemblies reinforced with gussets.

ENGINE AND ENGINE COOLING:ENGINE:OTHER FUEL TYPES:TURBO/SUPERCHARGER
I WAS DRIVING ON I-70 JUST OUTSIDE OF BRECKENRIDGE COLORADO, AT APPROXIMATELY MILE MARKER 228, GOING UPHILL AT A SPEED OF 65 MPH. TRAFFIC WAS RATHER LIGHT AND I WAS BEHIND A CAR WITH ANOTHER PASSING ME ON THE LEFT SIDE, ON THIS 2-LANE PORTION OF THE INTERSTATE. WHEN INSTANTLY, THE TRUCK ACCELERATED FROM 65 TO 100 MPH WITHIN 5 SECONDS. THE JOLT THREW ME BACK INTO MY SEAT AND I HAD TO TAKE IMMEDIATE ACTIONS NOT TO HIT ANY OF THE CARS AROUND ME. MY BRAKES DID NOT RESPOND. I COULD NOT GET THE TRUCK OUT OF GEAR AND TURNING THE TRUCK OFF MADE NO DIFFERENCE. I HAD TO PASS BOTH CARS ON THE SHOULDER OF THE ROAD. THE TRUCK CONTINUED TO ACCELERATE IN EXCESS OF 120 MPH AND WITHIN 30 SECONDS, THE TRUCK LOST ALL POWER. BY THEN I WAS GOING DOWNHILL AND COASTED APPROXIMATEDLY 3/4 OF A MILE BEFORE PULLING OFF INTO A REST AREA. I CONTACTED MY DEALER, DIAMOND INTERNATIONAL, WHO INSTRUCTED ME TO REMOVE THE RUBBER TUBE BETWEEN THE TURBO AND THE CHARGED AIR COOLER AND INSPECT FOR ANY OIL. I FOUND OIL IN THE TUBE AND THEY INSTRUCTED ME NOT TO DRIVE THE TRUCK AND HAVE IT TOWED TO THE CLOSEST DEALER. THE TRUCK WAS TOWED TO MCCANDLESS TRUCK CENTER IN AURORA, CO., AND WAS DETERMINED THE TURBO HAD FAILED ALLOWING OIL TO PASS THROUGH INTO THE CHARGE AIR COOLER. . THE TECHNICAIN I TALKED WITH TOLD ME THE OIL ATOMIZES BEFORE ENTERING INTO THE ENGINE WHICH CAUSES AN IMEDIATE INCREASE IN SPEED AND ENGINE RPM HAD MAXED OUT TO 3,500 BEFORE IT SHUT DOWN WHICH LUCKILY CAUSED NO INTERNAL DAMAGE. I HAVE BEEN DRIVING A COMMERCIAL TRUCK FOR 30 YEARS WITH OVER 1 MILLION MILES AND HAVE NEVER EXPERIENCE AN ISSUE LIKE THIS. FORTUNATELY, NO ONE WAS INJURED.
