A fire risk in some Mack trucks, and braking problems on some International and Caterpillar trucks, have led to recall campaigns.
Mack Trucks is recalling 16,428 model year 2010-2012 CHU, CXU, GU and TD vehicles manufactured June 16, 2009 through July 18, 2011.
In the affected vehicles, the Electronic Power Distribution Module may be contaminated from water leaks in and around the windshield. If exposed to water leaks, contaminants such as road salts may deposit on the EPDM. Deposits of contaminants may result in the circuits being bridged, creating a high resistance short, increasing the risk of a fire.
Mack will notify owners, and dealers will inspect the EPDM. If contamination has occurred, dealers will replace the EPDM and address the leak, free of charge. The recall will begin in late April.
Owners may contact Mack Trucks at (336) 393-2000. Mack's number for this recall is SC0375.
Navistar is recalling 1,196 model year 2012-2013 International Lonestar, Paystar, Prostar, Workstar and 9900 trucks due to possible fracturing of brake S-cam brackets.
This could result in an inoperative brake on the affected wheel and would cause the vehicle to pull to one side unexpectedly during braking and/or increase the stopping distance. Either result may increase the risk of a crash.
The affected trucks are equipped with feature code 0504501, 0504504, or 04EWM Reduced Stopping Distance brake linings and with or without feature code 04WCS Greased For Life front air S-cam brakes.
Navistar will notify owners, and dealers will replace the S-cam brake assemblies with a brake assembly with cast spiders and S-cam tube bracket assemblies with reinforced gussets, free of charge.
The recall is expected to begin on April 21. Navistar's number for this recall 1450 which is an expansion of an recall, 13V231.
Caterpillar is recalling 181 model year 2012-2013 CT660 trucks, manufactured August 2011 through August 2012, that are equipped with the same feature codes, for the same possible problem as the Internationals.
Caterpillar will notify owners, and dealers will replace the S-cam brake assemblies with a brake assembly with cast spiders and S-cam tube bracket assemblies with reinforced gussets, free of charge.
Owners will be notified with an interim letter before the end of April and will be mailed an additional letter once parts are available to remedy the vehicles. Owners may contact Caterpillar at 1-888-614-4328.
Mack Trucks is also recalling 958 model year 2010-2015 LEU vehicles manufactured May 14, 2009, through Feb. 14, 2014, and equipped with a Cummins ISL engine.
In the affected vehicles, the exhaust pipe may disconnect from the muffler/catalyst. If the exhaust pipe separates from the muffler on a twin-steer configured vehicle where the vehicle is operated from the right side, the operator may be exposed to carbon monoxide levels which may cause personal injury.
Mack will notify owners. The manufacturer has not yet determined a remedy plan. The recall is expected to begin in late April.
Owners may contact Mack Trucks at (336) 393-2000. Mack's number for this recall is SC0376.
