I've tried passing smog now for 5 months and I keep gettting OB11 not ready. I've had my car looked at and serviced by two mech to run diagnostics - nothing comes up. I take meticulous care and have full records of my service records. I'm at a loss and although I've paid my registration - I cannot get current tags. I don't know what to do.

Notification code P64 is not being resolved in a reasonable time period. We have called the dealer/service center that sold us the car; autopark Chrysler Jeep 400 auto park boulevard cary, nc 27511; many times over the last 3 months only to be told they don't have the part and are not sure when they will get the part. This is not acceptable if the defective part creates an steering issue with the car that results in loss of control, a wreak, injury, or death (ESC)! this is not a recall for a piece of interior trim!!! it is a recall of a vital system of the car...the steering and brake system!

This is the second Jeep I've had with Jeep esp system that cannot be controlled safely with this program active on other than clean dry paved roads. It appears esp actually stand for extremely stupid program as the program has an extremely bad action of slamming on individual brakes at the worst possible times. On 12/19/2009 while traveling on bailey rd in kent county, mi the esp caused the lost of control of our 2008 Jeep Liberty on wet icy roads. We went around a curve and began to climb a hill the esp started slamming on one brake and then another thus throwing the vehicle from shoulder to shoulder of the road. I was only able to regain control of the vehicle after turning the esp off. In early may, 2010 I was involved in an avoidable accident with my 2008 Liberty when the esp prevented me from swerving to avoid another car stopped at a green light. After the impact my car started to spin the esp fired again causing a shift in car"S kinetic weight, causing the car flip and the steering wheel to spin sharply to the left breaking my wrist and totaling the car. After this accident a bought a 2010 Jeep Grand Cherokee which I've found cannot be safely controlled in other than ideal driving conditions with this dangerous program active. This problem is compounded by the fact that it cannot be fully turned off and it comes back on if the car is driven above 44 mph or the ignition turned off for any reason. Any idiot with any driving experience knows better than to slam on the brakes on wet icy roads. Any driver with any advanced driving skills is not going to slam on the brakes in a turn but instead will hit the gas and counter steer if they start to slip in a turn. Unfortunately this is when the esp slams on the brakes and tries to roll the vehicle. This program needs to be turn off until it can actually understand what the driver intends to do.
