The National Highway Traffic Safety Administration’s Office of Defects Investigation has concluded an investigation of Navistar ProStars. The verdict: a recall of nearly 15,000 trucks.

According to ODI documents, 2012-2013 Navistar ProStar trucks have accelerator pedals that do not return completely to an idle position after being depressed, increasing engine speed. The defect also prevents the engine brake from activating.

ODI opened the investigation on April 17 after receiving more than 1,000 complaints. More than 200,000 trucks were part of the investigation. Drivers’ complaints ranged from needing to apply more pressure to the brake pedal to pulling the accelerator pedal back from underneath with his or her foot. No crashes, property damage, injuries or fatalities were reported.

More than 70 percent of the claims involved manual transmission trucks. ODI investigators drove several affected ProStars, including automatic transmission trucks. ODI found that automatic transmission ProStars did not reach engine speeds high enough to compromise safety. Manual transmission ProStars reached speeds of more than 2,300 RPMs while at rest. The discrepancy was because of the differing architecture between the two transmissions, the ODI report noted.

Navistar has acknowledged the issue and plans to issue a recall. The recall number is 15V-776. Only manual transmission 2012-2013 ProStars are affected. Navistar will recalibrate the engine electronic control module to remedy the situation. Drivers can check for recall updates at SaferCar.gov.
