I've been experiencing failures with the steering angle sensor (code C121A) intermittently for over a month. In doing research with other owners of the LX series vehicles (charger, Magnum, 300) and Jeep vehicles equipped with the sensor it seems that this part commonly fails, often for an undetermined reason. Explanations vary between chafing and friction causing plastic chips to obscure the electro-optical sensor, to chafing or bad wiring harnesses. The inability of this sensor to initialize results in a lack of electronic stability control which could contribute to a crash. This problem is well documented and discussed on multiple online vehicle forums such as 300cforums.com, jeepsunlimited.com, lxforums.com, jk-forum.com, dodgeforum.com and a litany of other websites. Some even have threads discussing the possibility of recalls and service advisors telling customers it is a "common" problem, however daimler-Chrysler has not seen fit to take any corrective action or issue a recall, nor are there any tsbs that I could locate.

The esp and ABS light came on and the brakes where given me resistance when I apply pressure the brakes. Had a mechanic look at it and he changed brake sensors and it goes for a while but still having the problem. Finally took it to Dodge and they are checking the problem as of now.
