- Summary
- Nova Bus (Nova) is recalling certain 2013 LFS transit buses equipped with transmission oil coolers. In the event of a transmission oil cooler failure, transmission fluid may mix with coolant that circulates through the passenger compartment heating system. Exposure to transmission fluid may degrade the PEX connectors of the heating system, resulting in hot coolant leaking into the passenger area.
- Consequence
- Leaking coolant could come into contact with passengers, increasing their risk of injury.
- Remedy
- Nova will notify owners, and dealers will replace the PEX fittings with brass fittings, free of charge. The recall began on March 6, 2018. Owners may contact Nova customer service at 1-800-350-6682. Nova's number for this recall is CR4226.
- 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.

Has your Nova Bus 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 Nova Bus dealer can also check your VIN. Recall repairs are free.
