Keep getting an service engine maintenance message/ check engine light. No codes show up, most likely the coolant bypass valve everyone is having an issue with. Don't receive message when ac is off. Or when blasting heat. Reset and comes back. Needs to be a recall. I see there is a class action lawsuit pending.

Started seeing the message on the dashboard that says -??engine maintenance required visit your dealer-?? when I took it to get it checked out they said it was the coolant bypass valve, the worker at the Toyota dealership mentioned that it has been happening to other vehicles as well, so he knew exactly what the message meant. Upon doing my own research I found many others with the same issue on their RAV4-??s as well. This issue is not covered by their warranty

I own a 2021 RAV4 which I routinely get serviced at the Passport Toyota. On June 29, I took my car to Passport Toyota for service because the maintenance required message appeared on my car-??s dashboard. The service advisor texted me a list of recommended services for my RAV4. One of recommended services was to replace the coolant bypass valve. I agreed to the service at $800. On July 3rd the check engine light came on and the car begin to overheat. I was 2 miles away and immediately drove there to inform them of the issue. They checked my car in for service, and explained to me that a hose must have come loose and was the cause of a coolant leak. When I received my vehicle, the check engine light was off, and the car seemed to be in working condition. On July 23 the maintenance required message returned. Again, I immediately drove my vehicle to the dealership and checked it into the service department. My service advisor notified me that they needed to reset the maintenance required message, and it would go away. I received my car back and the maintenance required message was no longer there and seemed to be in working conditioned. The next morning, July 24 while driving to an appointment, my car started to overheat and the check engine light came on again. This time the car was smoking. I was less than 5 miles from the dealership so I took it back to the them and checked it in for service. After having my car in for service for one week, they called me and stated that the issue was related to me having blown a head gasket, and I would need a new engine. The service department continued to do test as required by Toyota to determine the cost of a engine and how much they would cover. Three weeks later, they told me that Toyota will pay half the cost and I have to pay $3200 out of pocket with only about year warranty. I brought my car in several times and clearly mistakes and misdiagnosis were made on their part which led to the destruction of my vehicle.

A warning message came up that the HYBRID SYSTEM MALFUNCTION contact dealer. This was confirmed by the dealer. According to the dealer and message boards at various web sites, the Hybrid System Malfunction is NOT uncommon. To fix the problem, a wire harness must be replaced with a replacement cost of $2000-$4000. When I asked what changes have been made to the replacement part to address the corrosion problem, the response was there might be a new coating but we do live in New Hampshire.

Engine maintenance light came on saying to go to dealer at 35,000 miles. The coolant bypass valve needs to be replaced in order to prevent the engine from overheating. Our repair shop coordinated with the dealership who admitted that they commonly see this issue on RAV4 and Corolla models, though there is no recall currently in place.

I could not gas it or move the car. I let the car sit after being towed, it ran fine as if nothing happened. I got a battery test and it was at 100% charge according to Autozone. The check engine light, battery light and steering light came on. No prior indications of this problem.

I had my 2021 RAV4 Hybrid in for a routine oil change at 59,150 miles. I have maintained this vehicle in accordance with Toyota's recommendations since purchasing it brand new. During their inspection, it was noted by the Toyota mechanic that the timing cover was already seeping, way before it ever should be for this age and mileage of vehicle. The dealership mechanic did not recommend anything be done at this time since it wasn't an "active leak", even though seepage will turn into a leak. They denied my request for them to inspect the gaskets and look for cracks in the timing cover while my vehicle is still covered under warranty. While they would not say why they refused to honor my request, I assume it is because my warranty is set to expire when my vehicle reaches 60,000 miles (only 850 more miles from then) and they want me to have to pay $3500 of my own money instead of theirs after my warranty expires. It is unsafe for me to continue to drive this vehicle due to the fact that a timing cover leak can be a serious issue for my vehicle. The timing cover helps protect the timing belt, which is crucial for the proper operation of the engine. If the gasket is leaking, it can lead to oil loss, potential engine damage, and even engine failure if not addressed promptly. There were not any warning lamps that indicated to me that there was an issue.

The engine block cracked and started leaking coolant. It is clearly a defective manufacturing of the block casting. The same engine was recalled several months before mine, but my manufacturing date fell just outside of the range they recalled in the same year. The problem was confirmed by Price Leblanc Toyota in Baton Rouge, LA, a new short block was installed and I was left footing the bill because Toyota Corp denies responsibility for it even though it is only 3 years old and has had ALL maintenance done through the dealerships. The initial coolant leak was first noticed on 10/17/2023. The vehicle repairs were completed by Price Leblanc Toyota and picked up on 12/13/2023.

When driving the car and stopping at a stop sign or stop light, the engine will shut off. The automatic restart occurs and with the headlights on the climate temp control display flickers While all the other dashlights remain bright. Many people are disabling the system. Since there is a switch you can press, defeating the system. Toyota sent a technical specialist who inspected the system. And since he couldn't find how to fix it, declared it normal. Apparently toyota designed the car to do this for some unknown reason. He stated That lights will dim when the car restarts. It is not dimming as if a current draw, it flickers every time. This of course, affects the fuel economy of the car, defeating the system, which many people do and creates a concern of why that one component flickers. Toyota installs a heavy 605A battery to operate this system Since there are so many restarts. Will this create a car fire at some point? I would imagine That it makes a difference in The cafe reporting since so many people Disable the system.

We were on a drive back from Nashville like normal. My mom had picked me up from work at around 07:15. The car started making strange sounds as we were driving down the highway. It started yelling at us to pull over to a safe spot and slowing down. All of the lights had come on flashing at this time. It didn-??t even make it to the shoulder; We made a stop on the triangle area for when cars come in from the exit. As soon as we stopped, smoke started engulfing us and 2 guys who saw this happening parked on the shoulder and came running out of their van with fire extinguishers and started telling us to get out. When we went around the car to check what was going on, we noticed the fire that had started from the bottom of it. They fired the extinguishers a couple of times to the bottom of it where we could see the fire but it didn-??t help much so we had to retreat to a safer spot. We called 911 to ask them to send assistance. Not long after, the front half of the car was engulfed in flames. 10-20 minutes later, the fire department came to extinguish the flames. Once they got the fire under control, they towed the car to the shoulder of the road where we proceeded to salvage anything that was salvagable from the car. Where I got my hands cut up from broken shards that were littered all over the interior. We waited for awhile for another form of transportation to be able to make it home and it took a little bit due to the traffic that this incident had caused. We got the car towed back to Toyota for evaluation of the incident. It was supposed to be done within 2 months, but we still hadn-??t heard anything about it going into 3. We called them to inquire about the car and the situation, and they said that they had closed the case and had to reopen it for further investigations. They had closed the case and not told us anything about it. We received an email on the 23rd of January that stated the vehicle was too far damaged for them to be able to evaluate anything.

I was pulling into a parking space with my foot on the brake, had just touched the parking bar, and the engine started racing. The car went forward over the parking bar before I cold stop it by stomping on the brake. The only thing stopping me from going over the side of the hill was a chain link fence. Luckily the brakes worked. This is a 2021 RAV4 and I have never had this problem before. I am scheduled to go into the Toyota dealer to have them look at it.

2021 Toyota REV4 with just over 5,000 miles. I got off from a parking lot and drove 1/2 miles, The screen shown "Vehicle Alert" and asked to check engine with message "A malfunction in the electronic control of the engine, throttle, or automatic transmission has been detected". I smell very strong gasoline, then stop the vehicle. I check the gas tank, it's normal. I opened the hood and saw a puddle of gasoline on engine part, between the battery and the engine but lower than the battery. It's so dangerous to drive with leaking gasoline so I park my car on a street

Vehicle stumbles on moderate acceleration from slow speed, hesitates shifting also. Problem has persisted since new. Dealers rep "they're all like that. can't find any problem. No warning lamps. I think there is a TSB but it seems well hidden. I feel it is a safety issue - acceleration from low speed compromised. We have 2 more 2021 rav4s in the family that do not do that. I believe Toyota knows about this problem. Also had a problem with vehicle slamming violently into lower gear when coming to a stop. Dealer could not find problem. I checked vehicle and found air filter housing not properly secured. I latched it properly and that seemed to solve slamming into lower gear problem. Dealers mechanic (?) must have not latched it properly after 12 month service. No telling how much dirt was sucked into engine while that was happening. The stumbling/ drivability hesitant shifting problem persists. Several people have reported this problem. One was fixed by a dealer attending to a software problem. This is a known problem that is being ignored. This has happened since new Jan 29, 2021.
