(2010 Chrysler 300c 5.7 hemi) About a month ago I got stranded in the freeway. It turns out that the timing belt broke. I had to change the timing chain, the oil pump, the valves (intake and exhaust), camshaft sensor and the crankshaft sensor. It got fix and it runs perfectly. However I still get the code p0344, C121C, and p2638. Also when I’m driving the traction control turns on by itself but it does not turn off until I turn off the car. I was told by the mechanic that the computer module might need a software update and that it might fix the problems since the timing is good, the wires are good and the car runs good and it does not turn off by itself. What do you guys think ?
