2004–2005 Optima AH-28 & 2004–2005 Optima Opus 29 + 1 more recall: fuel system
⚠️ What's wrong
On certain transit vehicles and trolleys equipped with cummins ISB-02 diesel engines built with emc controlled fuel lift pumps. Erratic voltage supply to the fuel lift pump causes premature electric brush wear internal to the fuel lift pump. This premature wear could result in fuel lift pump failure and in some cases may cause an engine stall condition.
💥 The risk
Should the engine stall, a vehicle crash could occur.
🔧 The fix
Cummins, in conjunction with optima bus, will notify owners and repair the engines by emc recalibration and replacement of the fuel lift pump at no charge to the customer. Owners may contact cummins assistance center at 1-800-DIESELS or optima bus at 1-316-779-7700.
Is the fix free? Yes. Safety recall repairs are free at any authorized dealer under federal law, including parts and labor. (Vehicles more than 15 years old when the recall was announced can be excluded, but most manufacturers still fix them.)
