Repeat problem. No start or crank. Computer code is for entire start circuit for low voltage on ignition side but the code reads "ignition switch" which is only one possible cause. GM dealer replaced original with a made in "China" version. Dealer also broke plastic tabs getting panels off. Original problem occurred before 15000 miles. Mechanic was able to bypass ignition and crank over the vehicle but could not identify the source of the issue without more specialized equipment. |

Check engine light comes on intermittently, with various codes reported when I take vehicle to the dealer. This latest time I went to have it checked, the Check Engine light was still on and multiple computer codes, for a few sensors, were reported. Dealer went with changing out the Mass Airflow Sensor (one of the reported codes) saying they have seen that part cause multiple other codes as well. This appears to have corrected the issue as the Check Engine light has not come back on since the repair. |
