- Summary
- 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.
- Remedy
- 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 http://www.safercar.gov.

Has your Caterpillar been repaired?
Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.
NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Caterpillar dealer can also check your VIN. Recall repairs are free.
