Two problems related to timing tensioner have been reported for the 2010 Dodge Challenger. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2010 Dodge Challenger based on all problems reported for the 2010 Challenger.
I was driving on I-55 northbound 10 miles north of bloomington, IL, when I lost power to the engine. I was able to get over to the side of the road. I attempted to start the car, but the engine would not start. The nearest dealership (sam leman) noted no compression and a broken timing chain and tensioner. This is the fourth time the vehicle has been at a dealership for engine problems (previous three in April 2013 for a faulty oil control solenoid). It appears that the broken timing chain is common with my model of Challenger (r/t sub model with 5. 7l engine (with vvt and mds) and automatic transmission).
While driving at highway speed the vehicle made a pop sound and lost power. I was forced off the highway as there were no shoulders and had to push the vehicle across traffic to safety. The timing chain tensioner failed, resulting in the timing chain breaking. This resulted in damage to the upper portion of the motor, including all intake and exhaust valves, marring on the pistons and cracked heads.
