My vehicle Toyota RAV4 Hybrid 2020 began lost power and jerk on highway driving and then following messages appeared: Hybrid System Malfunction, A malfunction in electronic control of engine, throttle or automatic transmission has been detected and check engine light. This happened in September 2024. Toyota dealership replaced the low fuel pressure sensor A after my complaint and vehicle diagnostic, but it did not help. I recently had the same problem while driving on the highway for a long distance.

I have a 20202 Rav4 Hybrid and the engine short block has malfunctioned due to no error on my part, in my research there was a recall for this EXACTLY this issues in other cars of this year/make/model - although my vehicle initially did not qualify for this I believe that this in fact related and that Toyota should be responsible for the repair or replacement of the engine. The car is currently with a Toyota Dealership Service Center, Lake City Toyota in Seattle, WA but they have not been helpful. They have given me vague answers and have sent the engine offsite to a machine shop and keep requesting that I pour additional money into fixing an engine that clearly had a manufacturer defect. My car has always been serviced at Toyota dealerships, as suggested by Toyota. My car has never had previous issues until the engine light came on one day, i checked the coolant and it was empty - first replaced the fluid, let it sit overnight, then drove it around the block to circulate the coolant - when the reservoir emptied again I immediately made an appointment to take it in. The Dealership has not given me any paper invoices or written confirmation/notice of what is happening aside form continuing to ask me to pay more money to fix an engine that is clearly related to the national recall issued.

Check engine light came on and noted a malfunction in the electronic control of the engine, throttle or transmission. When taken to the dealer they found code P012807 related to engine cooling and suggested a replacement of the thermostat. This part should have a life of 100k or 8-10 years and car currently has less than 60k miles and 4 years old. Asked the dealership about known recall 20TA04 - for engine cooling recall but they insisted my car was not impacted. This is a safety issue as it could result in overheating of the engine leading to fire hazards.

I had a message on my dash for "engine maintenance required" but my check engine light was not on. Coolant bypass Valve failed, it is definitely a known issue and the dealership knew the likely issue before the car was seen by any technician.

Engine stalled on highway, was fortunate other drivers allowed us to get to the inside lane and on the shoulder. It bucked a couple times a few minutes earlier. A host of warning lights came on the dash. car did restart after ignition cycled off and on. Had over 1/2 tank fuel. Dash warnings that remained on CEL yellow. parking assist Radar and lane assist. Power steering seemed weak. No cruise control. Over the next 550 miles with engine shut offs during fuel stops dash warnings went out and car returned to normal. No longer trust this car with 70,000 miles.
