Car fails to start when the key is inserted and turned to the proper ignition starting point. My mechanics says the car is not finding the safety chip inside the key and will not allow the car to start. I am having to replace the ignition and have my key re-programmed. This has been degrading over a period of months. Starting with a forcefulness of the key to make it start. The longer it has gone the worse it has gotten. Until it finally would not start at all. The repair will cost me $ 400. 00 plus having it towed. It is a failure of the ignition switch to recognize the key's safety chip inside the key. It has caused me to sit and wait for the car to start, sometimes reaching 30 minutes. I take very good care of my cars and his should not be happening.
Car engine kills while driving at all speeds without warning. This has happened 7 times in the last 23 days, the last time on interstate in the left at 60 mph. Car will not start for some time after but will start but stall again. The last time it stalled while turning across a 6 lane intersection with oncoming traffic at highway speed. First events occurred at 174. 5 miles on the odometer and was towed to the dealer. On the evening of 31 March 2010. Car returned on evening of 8 April dealer stating the instrument cluster caused problem with the coded key making the car think it was an unauthorized key. New instrument cluster would not load into the computers, dealer stated they had to force the computer loading. Car returned to me the afternoon 8 April and brought back to the dealer the afternoon of 9 April for same issue with 300 miles. Dealer states he is working with the manufacture on programming a new computer as this might be the problem but they are unsure, have never seen this before in a new car. Of the 23 days I have owned this car it has been in the shop for over 20 days. I have lost my trust in this car and feel there is something very wrong for it to stall while moving in 60 mph traffic or in the center of intersections.
