2017 Toyota RAV4: check engine light

Filed Dec 1, 2025 · Acceleration, Driver assistance · CA

While driving the vehicle on an uphill stretch of highway with cruise control set at approximately 65 mph, the vehicle suddenly slowed down without warning. A distinct clunk was heard at the same moment. The cruise control system attempted to restore speed, and the engine became noticeably louder, but the vehicle struggled to return to the set speed. The driver tapped the brake to disengage cruise control and manually pressed the accelerator to resume normal speed. The trip was completed without additional events. After parking, the check engine light illuminated and the cruise control system became disabled on all subsequent drives. No warning indicators were present at the time of the initial failure, and there were no vehicles ahead that would have triggered the collision-avoidance system. Two days later, the vehicle became an intermittent no-start and eventually failed to start entirely. The vehicle was towed to a dealership for inspection. Technicians confirmed an electrical malfunction and reported that the multiplex ECU was likely experiencing an internal short. A parasitic draw test showed an abnormally high current draw of approximately 113 mA, which disappeared when the dome-light fuse and later the multiplex ECU were disconnected. The failure is intermittent and appears to involve an internal electrical short within the multiplex ECU. The sudden loss of cruise control function, abrupt deceleration, and subsequent intermittent electrical behavior created a safety risk, as the electrical malfunction occurred without warning while the vehicle was in motion. The issue was confirmed by a dealership service department.

Vehicle surges when accelerating since it was new. Throttle goes dead where engine idles but now power at all. Does it from a standing start, does it on hills and when merging onto a freeway. Now it happens on cruise control, when set on 75 mph engine loses power and slows down to 45 for a few minutes then shutters and speeds back up to 75. This past month if you let the fuel get down to 1/4 of a tank it will happen all the time. On interstate this week it happened and slowed to 35 mph and wouldn't go any faster until more gas was added. No check engine light ever. Dealer has checked twice and says no codes found and can't get it to happen it's a intermittent problem. We almost got hit by a semi on the interstate this week week due to this happening and I was unable to get out of his way because I no throttle response at all.... But engine was idling that all. Had to turn the engine off for 45 minutes before it would have any throttle response at all. Drove down the emergency lane to the next exit and filled up with gas. Engine surged for next 60 miles home. This is a huge problem! I am going to my local Toyota dealer tomorrow to talk with them again about this problem. If they give me the run around again I am going to file a lawsuit against Toyota and the dealership!
