NHTSA Complaint #11460696 — 2019 TOYOTA RAV4

On 12-April, I filed Report #11460592 regarding stuttering and uncontrollable acceleration of Toyota RAV4, 2019 model year, <22000 miles, incident occurred 11-April. Vehicle was taken to Toyota dealership service department on 12-April, returned that day as described in previous report. On 13-April, one day after repair, exact same issue occurred. Family (with 2 children) driving on road, 45MPH speed limit. Hybrid system malfunction alert occurred again. Speed limited drastically to approximately 15mph, with occasional reaccelerating uncontrollably. Vehicle exited as safely as possible and returned home. Vehicle then taken back to dealership for service. Full text of Report #114605 (11-April incident): Driving on 35MPH limit road. Vehicle began to stutter. Vehicle began to communicate warning lights - "PKSB Malfunction" and "Hybrid System Malfunction" and "Check Engine" and alerted to visit dealer. After stopping at red-light, received warning to pull over and stop driving. Vehicle could not exceed ~10mph no matter how much accelerator was depressed and received warning that vehicle had ~2.5 miles until it would cease being able to be driven. For rest of trip to home (approximately 2 miles), vehicle would alternate between 10mph limited state and returning to full acceleration which led to very unsafe driving conditions and abrupt changes in speed. Reached home and parked in drive way. After a few hours, returned to vehicle to take to dealer for service. All 3 error messages remained but no further limitation to 10mph or abrupt speed changes. Dropped off for service at dealership. Dealer notes: "Hybrid system malfunction, check engine light - SCAN FOR CODES, FOUND U010087 LOSS OF COMMUNICATION BETWEEN PCW AND ECM / CLEAR CODES, UPDATE SYSTEM, OPERATING AS DESIGNED." Upon receipt from dealer, no further issues and drove home safely. Vehicle is a 2019 Toyota RAV4 Hybrid Limited, bought new in Jan. 2020. Approximately 23000 miles, no previous issues.
