Brake Electric Antilock problems of the 1999 Chrysler Concorde

1999 Chrysler Concorde v-6 3. Brakes drop to 20% power in cold weather. No warning. No brake lite on dashboard. 20% brakes are effective enough at at slow speed and initial departure from parking spot. Lack of full power is not evident until full power is applied. Brakes return back to 100% power after warmer weather. After prolonged cold weather, the brake pedal freezes in place. Rubber boot on piston forward of brake pedal covered with rusty dust & shows possible exposure to interior water leak. In process of repairs now.

While driving on I-95 at 60 mph the vehicle started rapidly accelerating on it's own with my foot off the gas pedal. Applied brakes and shifted to neutral. Came to a stop. Put car in park and then into drive and car rapidly accelerated, tires smoking! brakes applied at maximum pressure car still accelerated. Shifted to neutral and turned key off.

I put car in reverse in parking lot and it lunged forward at full throttle with tires smoking, sideswipping one vehicle and pushed parked 2nd vehicle 30 ft into parking lot isle. My foot never left the brake pedal (used to shift), and brakes were useless in trying to stop the car. After hitting the second car (totalling it) got car stopped by slamming gear shift lever into park. This is the 3rd instance of this happening in the milwaukee area that is known to us. Substancial injuries were incurred in second instance where car when through garage door with severe facial injuries. The 3rd car went through a window of a business. All 3 were 1999 Chrysler products. Chrysler refuses to accept any blame for the accident and sent us a form letter saying the car was okay when it left the factory. Our car was a Chrysler Concorde lxi, the 2nd a Chrysler lhs, and the 3rd a Dodge neon.

When the brakes were applied the pedal went to the floor, resulting in extended stopping distance, and causing a collision which resulted in minor injuries. Vehicle was tataled. The dealer has been notified.
