Has anyone experienced a similar problem? We brought our 3mth old grand Cherokee L for a recall to the dealer. While there we mentioned that there is a "grinding sound" when turning the wheels sharply. They kept the vehicle since were unable to figure it out. A week later after discussions with engineers, they narrowed it down to a "steering rack and pinion "issue and backorder the part. Got the vehicle back yesterday after being assured there was no safety issue in driving it and today while pulling out of the driveway the car completely stalls and now has to be towed to the dealer. WTH!? Any help or suggestions would be greatly appreciated!
