NHTSA complaint #10822795, filed 2016-01, 167,000 miles“2006 Gmc sierra quit running on a trip we were taking. It started missing and eventually wouldn't restart. The truck has 82k on it and is very well maintained. The engine would turn over but not start... No spark? It has been to various service mechanics as well as my attempt to figure out what is wrong with it. Many new parts have been used: icm, crank sensor, cam sensor, coil... No difference. This vehicle quitting on a very busy highway could have caused significant injury to myself and/or my passenger. …”
