“October 2006 I received this letter from Chevrolet. We want you to know that the fuel injectors in some 2003 model year Chevrolet silverado vehicles, equipped with a 6.6l duramax diesel engine, may require replacement because of high fuel return rates due to fuel injector body cracks, or ball seat erosion, or high pressure seal extrusion. Symptoms of these conditions include illumination of service engine soon (ses) light, low engine power, hard start, and/or fuel in the crankcase. This is not a recall. …”
