The short answer
NHTSA received Daimler Trucks North America LLC’s report on Jun 3, 2015. Copied from NHTSA on Oct 26, 2026.
Every line below is in NHTSA’s own words, with its source beside it.
What’s wrong with it?
If engine oil comes into contact with a hot surface, there is an increased risk of a fire.
Daimler Trucks North America LLC (DTNA) is recalling certain model year 2007-2016 Freightliner 114SD and M2 Business Class trucks, 2008-2009 Sterling LT8500 trucks and Thomas Built Bus Saf-T-Liner HDX transit buses equipped with certain Cummins Westport ISL G engines.
Excessive engine crankcase pressures may cause the 90-degree elbow of the vent tube assembly to detach from the crankcase ventilation breather, possibly allowing engine oil to come into contact with hot surfaces.

- NHTSA’s part: Engine and engine cooling: engine.
What should you do?
Cummins will notify owners on behalf of DTNA, and dealers will secure the ends of the 90-degree elbow. In addition, the electronic control module (ECM) will be reprogrammed with software that can adjust the engine output under misfire conditions to limit crankcase pressures. These repairs will be performed free of charge. The recall began on June 12, 2015. Owners may contact DTNA customer service at 1-800-745-8000 or Cummins customer service at 1-800-343-7357. DTNA’s number for this recall is FL-681.

What the record doesn’t say

- Whether one vehicle or seat has been fixed: only its maker, or NHTSA’s lookup with a VIN, can say.
- How many have been returned or fixed isn’t in the notice.
