The right rear axle shaft assembly wheel bearing seal failed. The right rear ABS Sensor, aka (rotational Speed Sensor, wheel speed sensor) failed. These parts are available for inspection. The vehicle unexpectedly accelerated without me pressing the accelerator as I approached a red light at an intersection, putting my safety and others at risk. I had to slam on the brakes with all my might to get the vehicle to stop from going through the intersection. The road was wet, and the front wheels locked while the rear wheels continued to be driven by the engine without any input from the accelerator pedal. Eventually, the vehicle stopped, and the engine acceleration went back to normal operation. The problem has not been reproduced or confirmed by a dealer or independent service center. The vehicle and parts have been inspected by me, as the vehicle owner. The warning lamps suddenly illuminated on the instrument panel just prior to the incident. The warning lamps came on as I was approaching the intersection. The warning lamps that came on were the engine diagnostic indicator lamp aka Malfunction indicator lamp, the Anti-lock brake system warning light, the brake assist system warning light, the electronic stability program warning light. I also hear what sounded like the ABS Control Unit rapidly cycling just prior to the uncontrolled acceleration while nearing the intersection. I used diagnostic equipment and performed a visual inspection of the components, concluding that they needed replacement. Grease from the leaking right rear wheel bearing seal fouled the right rear wheel speed sensor. The wheel speed sensor cable develops cracks near the wheel hub. I believe these parts are defective and can cause erratic, uncontrollable, unsafe driving risks that could lead to accidents and injuries. The symptoms and warning indications went away after the parts were replaced. I still have these parts as I feel they should be inspected by NHTSA personnel to make a safety recall.
