2021 Toyota RAV4: check engine light

Filed Aug 17, 2026 · Electrical, Engine · MA

2021 Toyota RAV4 (gas model) has experienced a sudden, unexpected engine stall/shutdown on a public road. The incident occurred while shifting into Drive after backing up in reverse. The engine immediately died without any prior dashboard warning lights or mechanical symptoms. The information screen displayed a message stating "Put Car in Park" or "Shift into Park." The vehicle safely restarted immediately after shifting back into Park and pressing the ignition button. This intermittent stall has happened three times under the exact same directional shifting conditions over the last 1.5 years, creating a high-risk scenario for a rear-end collision in active traffic. After previous incident (one year ago) when the engine stopped when shifting from reverse to drive, I took it to Toyota service. Dealership diagnostics could not previously replicate the issue due to its intermittent nature and the absence of a permanent check engine code. checked battery and performed health check.

While driving at highway speeds (approx. 65 MPH), the vehicle suffered a sudden and catastrophic loss of motive power. The "Hybrid System Malfunction" warning illuminated, followed immediately by a "Check Engine" light. The vehicle entered a fail-safe mode, then completely shut down. The steering wheel locked, making it extremely difficult to maneuver the vehicle to the shoulder in a dark, remote area with freezing temperatures. This presented an immediate life-safety risk to all occupants. Following the incident, the vehicle was presented to two separate authorized Toyota dealerships in the US for emergency assistance. Both failed to provide the standard of care required for a high-voltage safety failure. The first dealer refused to perform even a basic safety inspection or intake the vehicle, stating they had no hybrid technicians on weekends. They turned the vehicle away without safety warnings, forcing the operation of a chemically failing vehicle on public roads. The second dealer attempted to charge a diagnostic fee. However, when questioned, they admitted they also did not have a hybrid-certified technician on site. They attempted to bill for a diagnostic service they knowingly could not perform. This fraudulent charge was only rescinded after it was challenged. They subsequently refused further assistance, leaving the occupants stranded. The vehicle was eventually towed to a third dealer (in Canada) where it was diagnosed with severe corrosion of the High-Voltage Floor Under Wire Harness (MGR Cable), a known defect. The dealer confirmed the rear motor cable was corroded and required replacement. The repair involved replacing the cable and installing a "splash guard" cap. No prior warning signs occurred before the sudden highway shutdown. This failure is a result of the manufacturer's failure to adequately seal high-voltage components against corrosion and the dealer network's gross negligence in refusing emergency safety support.

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.

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.

I have a 2021 Rav4 gas LE. I bought it new in May 2021 and have 38,000 miles on it. I was casually driving the car going 30-40mph when the car dashboard lit up. The first notification I got was on the screen display saying a malfunction in the charging system was detected and to stop in a safe location. Next, all my dashboard lights turned on (tire pressure, traction control, check engine, ABS, brake, battery light, etc.) and got the following messages on the dashboard: - parking brake malfunction - pre collision malfunction - brake power low - stop in a safe place - secondary collision brake system malfunction - antilock brake system malfunction voltage ability - Voltage abnormality - steering power low And then finally, the “engine stopped” message when the emergency brakes engaged on their own while I was slowing down at a red light. Before this, I never got any warning lights or messages. I tried to get the car towed since jump starting the car didn’t work. The emergency brakes would not disengage in neutral. I had to call a tow truck. I took the car to the Toyota dealership. They said it was the battery and replaced it, but when I went to pick it up, the dashboard lights still wouldn’t go away even after resetting. The power locks still don’t work when the car is off and my key fob to unlock/lock also still doesn’t work. The display screen still isn’t turning on and the usb plugs in the car also aren’t drawing any power. The headlights and interior lights also don’t work. They said it’s an electrical problem but quoted me $520 to diagnose the problem ONLY since the car is now out of the 3 years/36k miles basic warranty. I have had this car less than two years and has 38k miles.
