I was stopped at a red light. When the light turned green and I pressed the gas, the engine sputtered and almost shut off. Just before I came to a stop, the engine revved up and the vehicle accelerated. The uneven acceleration is concerning. I recently replaced the gas cap and serviced the fuel system, which leads me to believe there is a defect with the engine. Later in the day, the check engine light went on and AWD system, cruise control, and lane assist were disabled.

Driving at a speed of 60mph I heard a strange noise arise from the rear passenger side of the vehicle and smelled a burning (electrical) smell. I cut off the heater and seat warmers as a precaution, slowing the car to a speed of 30-40mph. Approx. 2 minutes later, my dashboard lit up with about 4 consecutive warnings 1. Antilock brake system has malfunctioned. 2. Lane tracing assist has malfunctioned. 3. Rear cameras have malfunctioned. 4. Parking assist with automated braking (pa w/ab) has malfunctioned. Brakes continued to engage, but felt stiff as though they may stop working. Was able to safely take back-roads to my local dealer (vancouver mccords toyota) where it is still undergoing investigation.
