Electrical System Problems of Toyota Venza - part 1

While attempting to cross a busy street, I picked an opening in the coming traffic to cross, released the brake to allow the car to start rolling slowing, but when I pressed the accelerator , I got no response from the car and no acceleration at all for about 3 seconds. Leaving me and my family stuck in the middle of the street with oncoming traffic just seconds away from hitting us. In the 3 seconds span, I tried pressing the accelerator several times until the car finally responded. The car remained on the entire time. No errors or messages were displayed on any of the dashboards at any time. I have seen several similar stories in online forums with this model. Something is wrong and very dangerous.

Purchased a 2011 Toyota Venza almost 28 days ago. I haven't even made my first payment for my car loan. The rain here in florida has shown that it is raining inside my vehicle. I have contacted the dealer, I have contacted my insurance company. I have done research and it's a known issue with this vehicle. I need help in correcting this. I am not driving the vehicle because it was shorting out the electric in the car. I have a tarp over it now. Can you point me in the direction of where to turn?.

The left head light has failed. As a result, these are the functionality issues I am experiencing: 1. Loss of power to power mirrors. This causes issues because the mirrors do not retract, and have to be manually adjusted before each drive session. They have folded in while driving, causing hazardous driving conditions without use of the mirrors. 2. Windshield wiper fluid dispenser has lost functionality, causing hazardous driving conditions because I am unable to remove debris and liquid that obstructs my vision while driving. 3. Windshield wipers will only work on one setting, being the fastest setting 4. Dash panel not displaying information such as temperature, trip information, and proper odometer readings. Low fuel notifications not showing properly. I almost ran out of fuel because I was unaware or actual fuel levels 5. Lift gate not opening from key fob 6. Neither headlight will operate in "bright" mode, despite only one head light being compromised. This is a major issues that has affected many Venza drivers. There are a multitude of reports on reddit and other forums that discuss these issues. What's worse, is that Toyota has tied critical electrical components and functionality to a single headlight, which happens to be very costly to remedy (over $1000k). There were no warnings present, just issues identified after the headlight failure, and these are only the ones I have discovered thus far. This needs to be recalled.

-issue with electrical system. Unable to access to connect services (app, sos). Contacted Toyota three times to let them know about this issue. -collision warning/rear cross warning don't always operate. There is no sound or warning. -occasionally, screen turns off completely when driving. -navigation system is always confused and doesn't give proper directions. -carplay not able to connect to phone sometimes. - -.

While driving, the computer seemed to short out, going blank on the cars display, and all guages failed. The car kpet driving, but I lost power steering and brakes. It was difficult to control the car while getting to the side of the road. Once there, I turned the car off to see if things would reset. It would not. The car would not recognize that I had my foot on the brake to start the car. I eventually needed a tow, which was a stupid problem to have. The car was driveable, should be driveable, its the computer telling the car theres a problem when there isnt one. Once at the car shop the car started fine but failed to start again the next day. Now its not doing that behavior and the shop cant figure out whats going wrong. There are no codes to diagnose. What a stupid problem to have, a completely drivable vehicle, but a glitchy computer making the car unreliable. I am stunned that a modern car wont allow you to drive to a car shop, it would not start. . . The shop was 1. 5 miles away but yet I had to pay for a tow. There have been no other problems, so is it a ground, a short, a faulty display? theres no way to diagnose this or at least the shop is having a very difficult time with it. Are there other owners that have had this issue?.

The other day when I was backing out of a parking spot my car almost backed into 2 people. There was no alert from the rear cross traffic warning.

On 1/1/25 around 5pm when it was getting dark, I was driving in my 2022 Toyota Venza le on the highway in the rain when all of a sudden my left headlight off, windshield wipers stopped working and experienced a host of other electrical issues - engine temp doesn't read, apple carplay stopped talking to device, side mirrors lost power, traction control disabled. It was very dangerous as I lost visibility in heavy rain while on the highway. I was able to slowly drive the car home with hazard lights blinking all the way. There were no error messages leading up to the failure. Only my engine temp not being able to read when the engine was cold that morning. It quickly resolved once the engine warmed up. I drove my car to Toyota dealership in which they spent over a day isolating the issue to faulty headlight assembly sending error codes to the ecu and jamming other zones on the car. They unplugged the left headlight assembly and told me I was ok to drive home. Ultimately I asked for replacement of the headlight and the light was restored and all issues did not return. I no longer have the original headlight assembly for inspection. I made a forum post regarding this issue and 2 other recent Venza owners have reached out to me with same behavior which prompted me to make this safety report.

My wife and I stopped to get our mail at our community hoa mailboxes. I was driving. I stopped, set/engaged the brake hold button while my wife got the mail. She was about to get back in and suddenly the car lurched forward very rapidly and crashed into the neighborhood playground and the chain linked fence. I could not stop the acceleration and had to keep forcefully applying the brakes and the vehicle finally quit. I was able to steer to avoid some kids playing basketball. I could have injured my wife or others, it could have been very tragic. The 3 boys got out of the way and helped us afterwards picking up the car debris left all around. The damage happened very quickly. I felt such shock afterwards and trauma wondering what happened and what could have happened. The police did a report and took pictures, our insurance declared it a total loss. We have contacted Toyota and are waiting for someone to inspect it before it is hauled away. No warnings prior, the vehicle has worked well. As I managed to drive it home, we noticed a machanical error code after the fact.

I don’t have the specific date that this happened because it was several times. When I first got the car the Toyota app stopped working after a few days. I brought it back a couple times and they replaced the headpiece because the app system crashed. Then the carplay stopped working not long after the head piece was replaced and the app stopped working. After going to the dealership for eight or nine times they finally ordered me a dcm. While waiting for that part, the auto start via key fog was not heating up the car. So with presetting the defrost to be on for auto start, the hazards came on when I auto started it. I happened to have had it at the service department when it happened and the mechanic said he didn’t know how to shut it off so he had to disconnect the battery. While I was speaking with Toyota about it on the phone, they asked me to try it out to see if the problem was gone and it wasn’t and I couldn’t shut the hazards off. So I drove with the hazards on and eventually the hazards turned off, but the carplay screen completely shut off when the hazards turned off. Also, when the hazards were on the car didn’t shut off when I opened the door. Also, another incident was that there was an acceleration issue when going to accelerate from a stopped position at a light. When I pressed on the gas the car started to move and then it went to a complete stop as if I was pushing on the break, but I wasn’t on the break. I was on the gas. I even looked down to see that my foot was on the gas. After pumping the gas pedal, it finally started to go. All of the above issues so far seem to be resolved after replacing the dcm. Like I said there’s too many incidences above for me to give a date to which all of this happened but it’s within the last few months I got this car in August.

At approximately [xxx] on Friday, [xxx], my wife was slowly pulling into a stripped parking place at museum hill's lower paved paved lot on [xxx], in santa fe, nm that has three levels when the car suddenly bolted up and over the concrete curb and up a short hill where it faced the fronts of two vehicles; the car stopped (possibly due to automatic braking systems) and rolled backwards into a small tree resting off of the pavement on soil, but against the curb. There is front end dislocation of the right fender and the passenger door hits the fender if trying to open it. The right front tire is broken and the alloy wheel is damaged. After a disagreement with a towing company, I backed the car over the curb and onto the pavement where I installed the spare. The car seemed to be ok to drive and my wife drove it home 3 miles away on back streets. The car's event data recorder was inspected by an employee of eaa from denver in Toyota of santa fe's dealership shop on [xxx] and the car driven. Toyota's report from their legal claims analyst said that "pressure was applied to the accelerator pedal prior to the impact. " my wife was going to her regularly scheduled lunch time support shift at the [xxx], was pulling into her regular parking area, and did not press the accelerator to the floor causing this wreck. I believe that the power steering created a negative voltage drop that caused the concurrent calibration of the accelerator electronics to believe that full power was required at that instant. The safety of my wife was at risk, but no other person was nearby and damage to shrubbery was not consequential. This problem has not been confirmed by a dealer or independent service center. However, several papers on the subject have been written by ronald a. Belt, phd of Plymouth, mn, the latest dated 20 July 2024. The only inspection of the vehicle was on [xxx] by Toyota's eea service. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I am the primary driver of our 2022 Toyota Venza. On Wednesday, may 29 I had just taken the car through the splash automated car wash on 41st Ave. In capitola, CA and I was navigating into an adjacent space for use of the vacuum cleaners. As I took my foot off the accelerator to put the vehicle into park, it suddenly and unintentionally accelerated. It crossed the driveway entrance to the car wash, jumped a curb which was actually the top of retaining wall for the parking lot of the adjacent business, and sailed over the retaining wall into the parking lot which was over 2 feet lower than the level of the car wash. I was able to bring the car to a stop without hitting anything, but 3 tires were blown out and severe damage occured to the underside and front end of the car (we are awaiting estimates of the damage to the car). The airbags did not deploy. I had a minor shoulder bruise from the seat belt but no other injury. The car is at an auto repair shop awaitinng estimates and adjuster inspection. No report has yet been filed with Toyota but we expect to file today. No independent service center or other inspection has been done yet. There was no warning system notification prior to the incident.

The crash occurred at 2:50 pm on January 10, 2024 while pulling our 2021 Toyota Venza into a diagonal parking space on a slight upgrade. The vehicle surged over the curb, across the sidewalk and into a brick wall with gas pipelines attached to it. As this was happening, the driver yelled, “I don’t know what’s happening. ” the car then rebounded onto the sidewalk and was turned off quickly because of a gas smell. We exited the vehicle and tried to keep people away from the scene because of the smell. The passenger had great difficulty getting out of the car because the passenger side door was blocked by a tree in the median. The fire department cleared the area, the police interviewed both the driver and the passenger and the gas company arrived to repair the meters and pipes. No citation was issued. During a call on January 12, 2024 to cancel a pre-paid service agreement, we were referred to the Toyota brand engagement center who interviewed us before forwarding information on to the Toyota liability team. Toyota sent a contractual employee to download the information from the vehicle’s computer modules for further analysis by Toyota. On February 20, 2024, Toyota issued a report that stated the vehicle had no defects related to the accident and that the accelerator pedal had been fully depressed prior to impact. The report did not address other information that was provided to individuals investigating the incident, including information about the incident itself, information about a delayed acceleration event several days prior to the incident and notification from the local Toyota dealer the next day that a check engine light had come on around 2:50 the day of the incident followed a minute later by alarms indicating “airbag failure to deploy” and “hybrid system failure. ” the report also did not address the possibility of a problem with the throttle system, specifically the accelerator sensor.

The door lock actuators have all systematically failed on the car, so I can lock the doors manually, but anytime an electrical signal is sent to the lock (key fob, putting the car in drive, etc), the door locks do not operate. It is my understanding this is a known problem by Toyota across many SUV models. I have left my car unlocked on many occassions "thinking" it is locked, and I don't like driving with passengers in the car due to the safety issue of being able to open a door while the car is in motion when I "think" it is locked.

When I open the driver's side when car running, the check srs airbag system warning light comes on. It also comes on if I start car with door open.

It's its been about 4 times for myself and twice for my husband. When pulling out of parking lot onto busy street making a right hand turn, the car failed to accelerate so that I can merge onto the street. I almost got reareded twice because of this not being able to get up to speed. I have taken it to the dealer twice. The first time they told me there was a computer recall so he would do the update and it if it happened after that to bring it in. We'll it's happened many more times. And the dealer can't tell me what it is.

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.

While driving on the interstate the volume on the radio went to full max volume, blasting in our ears, scaring us and in a frantic mode tried to shut it off with no avail almost could have caused an accident. None of the controls on the panel or steering wheel would turn it off. Finally after numerous attempts in a frantic manner was able to power off the audio. Controls wouldn’t respond until I did a reboot the next day.

The contact owns a 2023 Toyota Venza. The contact stated that while at a complete stop, the vehicle accelerated without warning as the contact let his foot off of the accelerator pedal. As a result of the failure, the contact crashed into the rear end of another vehicle . The air bags did not deploy upon impact. A police report was not filed and no injuries were reported. The vehicle resumed normal operation after the failure. The vehicle was later towed to the dealer where they were unable to duplicate the failure. The contact was initially informed that the event data recorder did not record the accident. The contact was later informed that the vehicle control history showed that the vehicle's brake pedal was released and that the accelerator pedal was applied prior to the accident, the contact disputed this finding. The manufacturer was notified of the failure and a case was filed. The vehicle was not repaired. The failure mileage was 2,600.

The headlight housing prongs are incorrect. The bulbs are h11, but the housing does not fit h11. I have tried 4 different brands.

On or around March 10, 2023, as my wife and daughter were driving the driver's side heated seat started burning/smoking. Immediately, my wife turned off the seat and returned home. I found there was an existing recall for this issue but only for the southeast Toyota distributors, I purchased my car in missouri. I took the vehicle to the local dealership in clarksville, tennessee. Not only would they not honor the recall, but charged me $115. 88 to confirm the burning of the seat. I contacted Toyota 7 times thus far and they are refusing to help because the recall only affected the southeast distributor group. I find this ludicrous as all the vehicles were made at the georgetown, kentucky plant. I simply want the remedy that southeast Toyota distributors gave their customers: removal of bad heating unit, return of $115. 88 charge of confirmation, and a return of the accessory charge I paid in December 2009. Thank you, matthew miano.

The car has a new type of sunroof (stargaze) that turns clear or dark. It is operated by the electrical system. Mine shorted out and makes a buzzing sound if turned on. This same problem has been reported by many others with this sunroof. It is a design defect that is prevalent in the Venza. The Toyota Venza is a low volume vehicle and a very small percentage are equipped with this sunroof, but l have read about many others experiencing this issue in Toyota forums online. The pictures show the roof in clear mode and frosted mode with the shorted out burnt portion.

Dear NHTSA, I hope this message finds you well. I am writing to bring to your attention a matter of significant concern regarding water leakage in my vehicle, which I believe has the potential to compromise the safety and functionality of the car's electronic systems. I would like to submit this report to the national highway traffic safety administration (NHTSA) to ensure that appropriate measures are taken to address and rectify this issue promptly. During the rainy season, I have observed water leaks occurring on both sides of the front section of my vehicle. This water infiltration has raised serious concerns about the possibility of damage to the car's computer system, thereby posing a potential risk of car malfunction. The electronic components of modern vehicles, including vital control units and sensors, are susceptible to water damage. In the event of such damage, there is a heightened risk of malfunctions that could compromise the overall safety and performance of the vehicle. Furthermore, I have identified an additional water leakage issue through the panoramic roof at the backside of the car. This raises the likelihood of water seeping into the interior of the vehicle, potentially damaging interior components, electrical wiring, and compromising the structural integrity of the car. I am reaching out to the NHTSA with the intention of highlighting the severity of these issues and advocating for a comprehensive investigation into the water leakage concerns in my vehicle model. I believe that swift action is necessary to prevent any potential safety hazards that may arise from compromised electronic systems or structural damage due to water infiltration. In light of the safety implications associated with water damage to the vehicle's electronic components, I urge the NHTSA to initiate a thorough examination of this matter. Your prompt attention to this matter is crucial in ensuring the safety of drivers and passengers who may be affected by similar issues.

The heated seat on the driver side is creating a burning smell. I have read about numerous other issues with this model that have had recalls but not mine. This seat is still in tact and available for full inspection upon request. This is a major safety issue that is known about but not addressed. Major fire risk putting anyone inside vehicle in danger. I have a 2 year old daughter and if I didn’t have a lot of electrical and vehicle knowledge I could have easily left the heated seat on not knowing and caused a major risk for my entire family. Toyota needs to add the rest of the vehicles that have these issues into the recall. I have not taken into dealer yet just informed my wife not to use heated seat. I plan to take in soon to dealer but with a known issue it should be covered by a recall and not out of pocket. No police, insurance or manufacture have inspected yet. No warning lights on at all.

The contact owns a 2010 Toyota Venza. The contact stated that while making a turn in either direction, the vehicle would lose motive power and stall. After coasting to a complete stop, the vehicle was restarted and the vehicle operated normally. The battery and battery cables were replaced however, the failure persisted. The manufacturer and local dealer were not notified of the failure. The failure mileage was 100,000.

While driving, vehicle suddenly lost all engine and electrical power and steering locked up. Fortunately I was stopped at a light at the time. Car restarted after I shifted into park and started in normal manner.

When coming to a faster stop, vehicle stalls entire system shuts off. Happened before when driving. Lucklily was not in a place to wreck.

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.

The contact owns a 2021 Toyota Venza. The contact stated while attempting to start the vehicle, several unknown warning lights illuminated. A dealer was contacted. The contact stated that during the first failure, the vehicle was towed to the dealer to be diagnosed, however the diagnosis was unknown. The contact stated that during the second failure, the steering wheel warning light illuminated, the steering wheel became difficult to turn, and the accelerator and brake pedals seized. The contact turned off and restarted the vehicle, and thirty seconds later, the vehicle operated as intended. The contact stated that during the third failure, the contact became aware that the fuel gauge was not operating properly. After refueling the vehicle, the fuel gauge warning light illuminated.

Water leak from panoramic sunroof when it rains. Side pillar posts. Have read several reviews including: shorted out the power window controls, owners had to dismantled moonroof on their own to add sealant or glue. This should be Toyota's responsibility as a factory issue. Dealers are not taking responsibility for it. Issue has been going on for about 2yrs but I just found out I could make complaint here. Please assist.

I have posted the most recent incident because this has happened multiple times since the time I purchased this car used in 2017. Something is causing the power to drain from the battery I have replaced the battery 3 times since 2017 I was told that I wasn't driving the car enough to keep it charged if I left it sit for 3 days without starting it.
