Vehicle stops running while driving, power steering stops working as well as the power brakes. Dangerous on highway. Had the crank sensor replaced due to this problem. Thought the problem was resolved but the same problem happened again on 12/22/14.
I was driving about 40 mph on a four lane highway in traffic when my car engine suddenly shut off. The brakes seized up, but I was able to get the car was able to get the car off on the shoulder. After trying several time to restart the car, I called for assistance. By the time assistance arrived, I was able to start the car and I drove it approximately five mile to my Jeep dealer. They found that the crank sensor was faulty and that was why the engine had shut down. The cost to replace the sensor was $275; however, because shutting down the engine caused the breaks to seize up, the breaks and calipers had to be replaced increasing the total cost of repairs to $1567. If I had been driving at highway speed when this occurred I would probably not be writing this letter.
