Transmission Gear Indicator problems of the 2007 Jeep Grand Cherokee

While driving the vehicle, had a sudden lose of ability to accelerate, no throttle response, no rpms on the tach, and every gear indicator was illuminated as if in all gears at the same time (park, reverse, nuetral, drive). Dealership says its part # 52124137ac that needs to be replaced, and is not covered under any power train warranty, at a cost of $817. 00. This problem happened 4 times before I was able to get it in to the local dealership, never on the highway, if it had happened on the highway, im sure I would have been taking a chance with my life.

While driving the vehicle loses power no matter how much ags you give it. The engine l;ight comes on and off every few days. All the gear indicator lights are highlighted.

Auto transmission gear shift not shifting into gears correctly; loss power around curves; sometimes engine light comes on; sometimes all gear indicators come on dash; feels as though can't accelerate when entering onto highway or passing. Nothing done yet. Called dealer, online searches. Very very many same-similar online & very expensive repair $700+. Appears to be defective part & should be recall/dealer replace/repair!!.

My daughter was driving her 2007 Grand Cherokee away at college. Several times as she was driving along the roads with traffic, the transmission seemed to go neutral and all gear indications lit circled as though it was in all gears, but was not "driving". When it finally kicked back into gear it accelerated quickly. She had to break and pull over several times this happened. We had the car towed to a dealership and they replaced an electronic module. This could be a deadly failure. Two dealerships' service departments I have asked have heard of it but say it isn't a widespread problem, a sales manager where we bought it claims never to have heard of this.
