2014 Dodge Durango LTD 118,000 miles.
I purchased a used Durango that had a history of front end damage but all seemed to check out okay. Front end shop stated rebuild looked good. The problem is that the steering is ultra sensitive. If you move steering wheel abruptly the vehicle just "jumps" that direction. One mechanic told me that they could have replaced the electro hydraulic unit with wrong item. Frame is straight with no apparent alignement issues. Also, occasionally, it will not shift up when starting out from a stop. Computer issue?

Surely will apppreciate any suggestions.
Thanks
