One problem related to crankshaft position sensor has been reported for the 2009 GMC Yukon Hybrid. The most recently reported issues are listed below.
While driving on the highway between 65-70 miles an hour my vehicles check engine light came on and la message of engine power reduced appeared. The vehicle loss power but I was able to make it to the shoulder safely. The car would not turn on and I had to cal aaa to take my care to the dealer. The dealer said that the valve body internally shorted the memory circuit and the crankshaft sensor shorted. The dealer said that they found the harness for the crankshaft had melted and shorted out the sensors. They repaired the harness, replaced the shorted out sensor and replaced the valvebody/tcm. Do not know what caused the valve body to short and cause the crankshaft sensor to melt.
