The contact owns a 2003 Mercury Grand Marquis. The contact stated that while driving 20 mph, the brake pedal was depressed and the engine rpms increased approximately to 4000. The contact stated excessive force was applied to the brake pedal and the vehicle jerked. The brake pedal was aggressively depressed until the brakes responded and the vehicle was able to come to a stop. The vehicle was taken to the dealer where the failure was unable to be diagnosed. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 130,000. The consumer stated when he applied the brakes, the vehicle slowed down. However, the engine speed increased to 4,000 RPM's/ with the brake fully depressed, the vehicle continued with a series of lunges at a high speed. Only by releasing the brake pedal and slamming on the brake, did the vehicle stop about three quarters across the intersection with the engine at a normal idle speed. No warning lights displayed on the dashboard. The vehicle had a history of almost stalling while coming to a stop. The dealer did not find any codes. Updated 12/04/14
