2021 Toyota Venza Hybrid

This report covers 2 events for the same problem. The first occurred in the spring of 2025 and I did not document the date or time. The second one occurred on November 10, 2025 @ about 10:15 a.m. (1) Last spring my wife was driving the Venza up the street to our residence going a slow rate of speed. As she approached the house, she took her foot off on the gas and coasted toward the left curb so she could back into our driveway. At that point, car suddenly surged forward and accelerated toward the curb. My wife rapidly applied the brake and averted any problem. (2) The second event occurred on November 10, 2025 @ 10:15 a.m. My wife was starting to park at a parking lot in the Tanasbourne Town Center. She was going to back into a parking spot so she drove forward going slightly left. Then, with the car still in drive, the car surged forward. She quickly stepped on the brake and the car stopped abruptly. (She was angling the car and was about ready to stop and put the car in reverse when this happened) Again, with her quick response braking, she was able to avert hitting person or thing. As to which component or system failed, there appears to be a random malfunction of sensors or perhaps the CPU...something that is calling for full throttle when the gas petal is not pushed. The safety risk is possible harm to the driver, outside property, or the worse situation would be harm to pedestrians that might be in the way of the car. We have not been able to reproduce the problem. The same maneuvers have been repeated 100's of times without incident. As of this writing, the vehicle is being taken to the Toyota dealer to have the oil changed and at that time they will be asked to do a thorough inspection of the systems that might cause this, check for any recorded malfunctions, etc. To the best of our knowledge, there were no warning lamps or messages that appeared.

I was stopped at an intersection. When I pressed the accelerator to try to pull across the intersection, the vehicle initially began to move forward but almost immediately all acceleration power was lost. The accelerator pedal could be pushed to the floor with no response from the vehicle. It took several seconds of feathering the accelerator for the vehicle to regain the ability to move forward and I was able to clear the intersection. This is the fourth time that I have experienced the same issue with this vehicle over the past two years. The problem cannot be replicated by the dealer. There are no warning lights on in the vehicle. I don’t know if warnings appear during this few seconds of power failure because it happens very quickly and my focus is trying to get out of the way of oncoming traffic. This is a serious safety concern because it has occurred while trying to move through an intersection or pull onto the road. The vehicle losing power and stopping in these moments could result in a collision with an oncoming vehicle.

Vehicle at operating temperature, running, in gear and at a stop. Making a left turn into traffic. I release the brake and apply the accelerator, the car rolls out into traffic but no power, I press more and more until it is 100% throttle, all the way to the floor. Then after about 5 seconds the vehicle moves forward. Complete loss of response/power for 5 seconds. Thankfully no traffic coming. This happens a second time with the same circumstances, different location. Press the accelerator, no response, sudden loss of all power, then after 5 seconds it responds. This time there is traffic coming to my driver's side at 50 MPH, I was trying to press harder but it wouldn't respond. There were no warning lights, MIL, sounds or messages. Toyota wants $169.99/hr plus tax to investigate.

When accelerating from a stopped position, the car fails to go forward. This incident has occurred six times and often seems to be at the worst times, such as pulling into a busy road from a stop sign. The car will start to accelerate and stop with no response from the gas pedal for 3-5 seconds. There have almost been a couple of accidents with this vehicle because of this issue. No check engine light or any light at all came on in the car when this incident occurred. This vehicle has been taking to the dealership and the problem has been mentioned to them, however with no codes to read for the OBDII they claim there is nothing they can do about it.

On three separate occassions, when applying the gas pedal, the car did not immediately accelerate. One time I was pulling out across two lanes of traffic and the accelerator was to the floor and nothing happened for about 5 seconds. The last time happened today, 11/3/23, leaving a gas station entering traffic. I hit the gas pedal and it was 3/4 the way down before the car moved which, once again, could have caused a accident pulling out into traffic. I took the car into Jones Junction with the complaint and they could not find any issues after allegedly checking the fuel pump. Online other individuals are having the same problem.

On May 30, 2023 at approx. 11:30am I was leaving the car wash located at 2330 Olympic Hwy. N. Shelton Washington. The automatic bar pushed me through the car wash to the end where it left you. There was a slight grade downwards to the highway (Olympic Hwy. N.) I touched the gas peddle slightly and the car surged forward across the SB lane where a car traveling SB had to slam on its brakes to avoid a collision. My car continued across to the NB lane where it struck a vehicle in the drivers side rear quarter panel. I had slammed on the brakes but not quick enough to avoid the collision. The brake was slow to respond when I applied them. I'm thinking what may have happened as this is a gas electric hybrid that the gas engine kicked in instead of the battery when I gently applied the gas peddle which caused it to surge forward.

On numerous equations, when I press on the gas pedal the car does not react from either the hybrid battery or from the engine. I will depress the pedal and the car pauses for a few seconds before it moves forward. This has happened multiple times at different mileages but until this report, I did not think much of it since it was not in a near collision situation. On two occasions as I am pulling into traffic I will put my foot on the gas and since I get no reaction, the cars coming towards me have been very close to hitting me. One would have been a T bone incident where I would have been hit and another would have been a rear ended situation. Both times, the cars coming towards me had to brake rapidly. I have taken the issue to the dealer to examine. There have been no warning lamps and it does not happen consistently.

While steadily accelerating on a freeway onramp, the vehicle suddenly accelerated, surged and gained speed rapidly without my control. I took action by braking and slowing the vehicle to a safe freeway speed. Thankfully no one in my vehicle was hurt and no other vehicle was near during the incident. There were no warning messages. The first time I experienced this unintended acceleration was the first month when this brand new vehicle was purchased from a local Toyota dealer. I was turning into my driveway from a residential street , the car suddenly accelerated while I was in the middle of turn. I immediately/emergently stopped by stepping on the brake, I could have crashed into the power pole if I did not stop. Because this was a new car, I convinced myself I was unfamiliar with its controls. But since the second occurrence, I am greatly concerned about this random "unintended acceleration". The Toyota Venza had been dropped off at our local Toyota dealer for inspection and hopefully repair.

Twice in the (almost a)year I’ve had the Venza I have gone to accelerate from a stop sign and the car started to go then the gas pedal went all the way to floor and nothing happened - then when I tried again the car accelerated as expected. The first time (@ approx 4000 miles) I was turning left with oncoming traffic (of semi truck plus others) coming and had it happened a few seconds later - I would have been in a serious accident. Second time was just over 10000 miles on 1/12/2021
