- The problem
- Certain medium duty c-series and b7 school bus chassis equipped with a 7.4 Liter gas engine and an impco lpg conversion kit. Some of these vehicles may have engine backfires with sufficient force to damage the engine air intake system and the air cleaner filter element.
- The risk
- If the damaged air cleaner parts are dislodged from their normal position, these parts could come in contact with the hot exhaust manifold and/or hot exhaust gas recirculation (egr) valve tube resulting in a possible engine compartment fire.
- The fix
- Dealers will install a redesigned mixer bonnet and air cleaner housing cover, selective upgrades in various connections related to the air induction system, and if needed, a new air cleaner filter.

- The problem
- Vehicle description: school buses, medium duty trucks and tractors built with bendix air abs with an ec-17 1030r electronic control unit (ecu), there have been reports of unwanted abs activation at low speeds caused by 1) chafed abs wheel speed sensor wires on rotating parts or 2) a damaged component at the wheel end that generates a certain type of erratic sensor signal.
- The risk

- The fix
- DEALERS WILL REPLACE THE ABS ECU.
