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.
Car makes a whining noise Toyota Pinellas park said it was normal but the transmission is jolting/slipping not accelerating vs the first test drive. Both cv axles were bad tires were bald when sold to me tps sensors were bad. Had to get a new set of tires and paid the Toyota for work on the vehicle
Upon taking my 2021 Rav4 Hybrid in for the rear traction motor cable corrosion recall (25TD01) on 5/7/2026, I was told there are no parts, no estimated arrival time, and therefore not even a rough estimate for a timeframe of repair. I was told that no one would inspect or evaluate the part in question to indicate if the car was safe to drive. I expressed my extreme concern given the recall includes risk of power failure, even while driving. I received inconsistent, avoidant answers and an absolute denial to remedy the situation in any way. I was told the dealership is "Dolan" and not "Toyota". I again expressed my concerns about safety and the dealerships' denial to, at minimum inspect the recalled part and/or housing of the part. Emily, the Service manager stated that Toyota does not "allow" loaner vehicles for this particular recall. She could not provide any sources for this information. To summarize; the dealer with not provide an inspection of the recalled part and/or housing, or give an estimated timeline for repair given I am #125 on a waitlist. There is a complete lack of regard for mine or my children's safety as the dealer will not provide any assessment of how bad the damage could be. They suggested that I continue to drive the vehicle, acknowledging all of the safety hazards that could occur. I am terrified of the possibility of having an accident with my kids in the car due to this recalled part failing, not having a vehicle to get to and from work, and the potential additional costs that this unaddressed recall issue could cause. Please advise!
My Toyota hybrid AWD vehicle experienced corrosion of the rear traction motor cable, which Toyota has acknowledged in Service Campaign 25TD01. This corrosion affects the electrical connection to the rear drive motor and can result in loss of AWD propulsion capability. Loss of rear-wheel propulsion significantly reduces traction and stability, particularly in snow, ice, and wet conditions. Drivers may believe the vehicle still has AWD capability when in fact the rear drive system is compromised. In addition, the vehicle’s adaptive cruise control system repeatedly turned off unexpectedly while driving and displayed “unavailable” warnings. These malfunctions occurred alongside the electrical issues related to the rear traction motor cable corrosion, suggesting the defect may affect multiple vehicle systems. Toyota has acknowledged this defect through Service Campaign 25TD01 but has not issued a safety recall. Given the potential for loss of propulsion and malfunction of driver-assistance systems, this issue should be investigated as a safety defect.
This complaint is being filed as a follow-up to a previously submitted the federal safety agency complaint regarding door lock failures on my 2021 Toyota RAV4 Hybrid. Since the original complaint, a second door has now failed. In addition to the front passenger door, the rear passenger-side door will no longer lock or unlock electronically using the key fob or interior power lock button and must be locked manually. When attempting to lock the vehicle, the vehicle emits a warning beep indicating a door is unsecured, even though some doors appear locked. Upon inspection, the rear passenger door was found unlocked. This issue appears to be progressive, affecting multiple doors. Doors may appear locked when they are not, creating a security concern.
Driver door lock actuator. When using the vehicles remote key, the driver door does not lock and unlock with the rest of the vehicles locks. This failure can cause theft of personal property in the vehicle or theft of the vehicle itself. The problem has been confirmed by other toyota owners with similar models. No warning lights of the problem appeared.
I am reporting a safety defect involving the front passenger door lock actuator on my 2021 Toyota RAV4 XLE Hybrid. The front passenger door will not lock or unlock using the key fob or the interior power door lock button. The door must now be locked manually. This defeats the vehicle’s automatic locking system and creates a safety and security concern. This condition prevents all doors from being secured properly when driving or when parked. A passenger may believe the door is locked when it is not, increasing the risk of unauthorized entry, theft, or passenger safety issues. The failure occurred during normal use and without warning. The vehicle has been properly maintained. I have learned that multiple Toyota RAV4 owners have reported similar door lock actuator failures, indicating a potential widespread defect. This issue occurred shortly after the factory warranty expired. Due to the safety implications, I believe this issue warrants investigation and possible recall or manufacturer repair program. “This failure occurred without warning and with no dashboard alerts.”
‘Voltage abnormality, power steering low’ error message has appeared three separate times. All while vehicle is idle at stop light or parked, last incident car was unable to restart immediately. All dashboard lights came on, including message saying parking hold unavailable. Mechanic confirmed no issues with 12v battery health and unable to recreate issue. Loss of power is risk to safety, possible draining of battery due to unknown issue
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.
