Surging at fully closed throttle accompanied by abs failure is a real issue with this vehicle. This is a common problem acknowledged by the manufacturer. Prm chip replacement to fix the surge problem should be a safety recall. My 1997 Land Rover Discovery would not stop at a stop light when letting off the accelerator because the rpms surged on the vehicle. Upon attempting to depress the brakes the abs malfunctioned causing the vehicle to continue to accelerate due to lack of brakes and an elevated rpm level. This is an electronic defect that needs immediate attention due to the number of vehicles which experience this problem and the acknowledgment by the manufacturer that rpm surging at fully closed throttle requires the replacement of a revised chip to remedy this. This vehicle is of no use to me because it is unsafe to operate and thus unsuitable for road use. I am seriously considering contacting other sources/media outlets to investigate this common problem.
Abs brakes began to systematrically engage on smooth surfaces, abs system engaged, instead of stopping the vehicle began to surge forward, to avoid colliding with other vehicles consumer drove onto the cement barrier until vehicle stopped. Possibly related to the fuel, throttle, linkages and control as well as the abs system.
Accelerator pedal is too close to the brake pedal. When consumer attempts to press brake pedeal, the accelerator pedal, at times, is also pressed. This defect has caused consumer to be involved in a crash.
