2012 CATERPILLAR CT660 Recalls (3)

Campaign:
12V051000 on 02/12/2012
Component:
Service brakes, air:supply:check valve
Manufactured:
12/01/2010 - 01/25/2012
Affected:
104
Defect:
Caterpillar is recalling certain model year 2012-2013 ct660 commercial trucks, manufactured from december 2, 2010, through january 26, 2012, and equipped with bendix atr-6 traction relay valves. in extremely cold conditions, these bendix relay valves may potentially develop internal leakage. internal leakage can lead to air pressure being delivered to affected primary or secondary brake causing continuous brake application.
Consequence:
Unexpected continuous brake application can cause the brakes to overheat and lead to a fire. unexpected continuous brake application can cause the driver to lose control of the vehicle, increasing the risk of a crash. also, the brakes may be applied without illuminating the brake lights, failing to give proper warning to other drivers.
Correction:
Caterpillar will notify owners, and dealers will repair the vehicles free of charge. owners may contact caterpillar at 309-675-5658.
Notes:
Owners may also contact the national highway traffic safety administration's vehicle safety hotline at 1-888-327-4236 (tty 1-800-424-9153), or go to <a href=http://www.safercar.gov>http://www.safercar.gov</a> .
Campaign:
13V072000 on 03/04/2013
Component:
Exterior lighting
Manufactured:
10/30/2011 - 01/22/2013
Affected:
49
Defect:
Caterpillar is recalling certain 2012 and 2014 caterpillar ct660 heavy duty trucks manufactured by navistar between october 31, 2011, and january 23, 2013. certain side marker lamps and/or reflective tape were not applied to these vehicles, which have a length of 30 feet or longer. thus, these vehicles fail to conform to the requirements of federal motor vehicle safety standard no. 108, "lamps, reflective devices, and associated equipment."
Consequence:
Missing side marker lamps and/or reflective tape reduces the visibility of the truck to others, which increases the risk of a vehicle crash.
Correction:
Caterpillar will notify owners, and dealers will repair the vehicles free of charge. the recall began on april 262013. owners may contact caterpillar at 1-800-447-4986.
Notes:
Customers may contact the national highway traffic safety administration's vehicle safety hotline at 1-888-327-4236 (tty: 1-800-424-9153); or go to http://www.safercar.gov.
Campaign:
14V068000 on 02/25/2014
Component:
Service brakes
Manufactured:
07/31/2011 - 08/29/2012
Affected:
181
Defect:
Caterpillar inc. (caterpillar) is recalling certain model year 2012-2013 ct660 trucks manufactured august 2011 through august 2012, and equipped with feature code 0504501, 0504504, or 04ewm reduced stopping distance (rsd) brake linings and with or without feature code 04wcs greased for life front air s-cam brakes. in the affected vehicles, the brake s-cam brackets may fracture.
Consequence:
S-cam bracket fractures may result in an inoperative brake on the affected wheel. this will 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.
Correction:
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. the recall began on april 11, 2014. owners may contact caterpillar at 1-888-614-4328.
Notes:
Owners may also contact the national highway traffic safety administration vehicle safety hotline at 1-888-327-4236 (tty 1-800-424-9153), or go to www.safercar.gov.
