I was driving around 30 mph when the vehicle suddenly turned off. The engine stopped running, all instrumentation turned off, no power steering and no brakes. The car became uncontrollable until it coasted to a stop.

I have noticed that when I am breaking, occasionally as I’m breaking there’s a sudden jolt, or lurch, forward like the car is accelerating. This is very disconcerting especially when there are other cars in front of me or people.

I was at a complete stop. There were no obstacles around me or oncoming. When I pressed the accelerator nothing happened for a full 3 seconds, until my vehicle jolted forward at an excessive speed. Brakes were not working.

The head gasket that was repaired failed and the radiator system also failed. Im not sure if these issues are dealer related or manufacture related as I spoke to the previous owner and they stated they had the vehicle serviced at a manufacturer prior to doing a trade in with the dealer.

About 25% of the time when I come to a stop and I am breaking, the car surges forward slightly. At first, I thought it was the way I was driving or the fact that it is an ev vehicle, which I had not driven before, but overtime it seems it is just the way the car operates. Others in the car have felt it happen as well as I have come to a stop sign or stoplight. I have not bumped into another car or anything but feel that that could happen if this is not corrected.

I believe the computer caused the problem. The car is available for inspection as personnel at gettel Toyota in punta gorda claimed they couldn't touch the computer and have done nothing. Purchased Sienna in August 2021. In October at about 5:30 a. M. We were in the far left lane on a PA interstate, traffic came to a stop for construction. A delivery truck in front of us rolled backward a bit. When traffic started up again, our car would not go forward, only reverse. We tried "drive"--nothing--only had reverse. Finally, with cars whizzing around us, shut the engine off. Upon restarting, all gears were restored and we continued on to boston. We were shaken by this event. Since then, we have had numerous incidents of the car not moving when I put it (mainly) into reverse. I had to shut the engine off--restart--and it went into gear. Latest incidents--first week February 2024--I pulled into a parking space at englewood hospital. After visiting my husband, came out, started the car, put it into reverse--nothing. Shut the car off--restarted it, and it was ok. Ten minutes later, I pulled off onto the shoulder to take a call from one of his doctors and--no gears. Shut off the engine, restarted it and it was ok. I'm worried I'll stop for a traffic light on one of our 4 or 6 lane streets and get hit because our car won't go into gear.

The intake valve became burnt/stuck, causing my car to lose all compression on cylinder 3. The cel came on, flashing, and the car immediately started driving rough and not accelerating. I had the vehicle brought to 2 different auto shops that confirmed the issue. My and my childrens' safety were at risk as soon as we tried to turn right onto a high speed road and my car started the flashing cel and would not accelerate. There was no warning before this incident.

I have 2014 Toyota Sienna head gasket problem with less than 100,000 k.

Driving down highway noticed white smoke coming from car. Exited highway and warning light then came on saying engine oil low. Stopped van immediately on side of the road and had it towed. Appears the oil coolant line burst which is a known issue on these vehicles after google searching, but was never made aware. Always completed all recalls. Extremely dangerous especially with children in car.

Vehicle will not start every single winter! has been in the Toyota repair shop multiple times. Told me it was possibly the kick sensors that are activated in the cold, stay on and then run battery dead. It is currently 20 degrees outside, but was parked in the garage all night, and still won't start in the morning! completely unreliable. Nearest dealership is 1 hour away from me. Kick sensors were replaced last year, battery has been checked. Still happens. The vehicle is completely unusable and unreliable. Other issue- battery is in the back of the vehicle and you cant open the back door to access the battery to charge it! you have to get an external battery charger, charge front battery to open back door then jump back battery. If I was out and about I would have no way to do that. Absolutely unacceptable and a reoccurring problem. This needs recalled. Many others online report the same issue. Please respond.

Today 4/7/23 my 2017 Toyota Sienna accelerated on its own. I was driving my 4 children to school and we were at a stop light. When I took my foot of the brake to start making a turn the car gunned it around the corner. It scared everyone in the car half to death. Thankfully no one was hurt but it looks like others on here haven't been so lucky with this issue. I hope Toyota does the right thing a d fixes this issue before more people die.

Checking engine light on and off slide door not working properly.

The 2gr-fe engine on my Sienna has experienced a front timing cover leak. It's slowly leaking oil out of my vehicle and I'm afraid it will get worst over time. My vehicle has less than 100k miles and if the leak persists, I down want my vehicle breaking down and leaving me stranded.

I would like to make formal complaint in regards to a manufacture defect. I purchased my Toyota Sienna xse brand new in August of 2021 at cerritos Toyota in California. On December 24th at approximately 1:30 p. M. On christmas eve, after filling up gas at sam's club in fountain valley, CA. I pull out on to the street heading northbound on warner approaching intersection as I come to complete stop on red. All of a sudden, my Sienna completely shut itself off and the engine light came on. I put it back on park and restart the car. As I attempt to accelerate forward. The car jerk and the brake didn't work and the engine light came on. Fortunately, I was able to make a u turn and pull into a gas station near by ( shell) and I thank the lord almighty there was no car right behind me. I could of gotten rear ended. It was the most terrifying moment of my life. My wife and I was in the car at the time of the incident. We waited patiently over an hour for triple aaa to have it tow the nearest dealership next to my house in long beach, CA. My 2021 Toyota Sienna currently has 52,023 miles and sitting at the dealership to be repair at long beach west coast Toyota. I have contacted Toyota of this incident and they refused to fully covered repair instead they offered me 700 payment assistant the rest would come out of my pockets. I believed the car should be part of the campaign recall and nothing should come out my expense. I would like you you guys to investigate the incident and look into this matter as soon as possible because there thousands like my mind that could there have the same issue but was not part the campaign recall. A bulletin was published on April 13, 2022 affecting 2021 -2022 Toyota Sienna. Production period March 3rd, 2020 through April 7th 2022. Manufacture's campaign number: Toyota: 22tb03.

The vehicle was taken to a local pep boys where oil was added in the vehicle and the contact drove to his residence. However, the failure persisted while driving. The vehicle was towed to the dealer where it was diagnosed that the exhaust cam gear had fractured, causing damage to the engine and to other components. The dealer diagnosed that the engine , the exhaust cam gear and the timing chain needed to be replaced, and unknown repairs needed to be completed. The vehicle was not repaired. The contact related the failure to an unknown Toyota extended warranty. The manufacturer was notified of the failure and informed the contact that they could not assist due to the vehicle manufacture date. The failure mileage was approximately 204,000.

As a result of the transmission cooler being a part of the radiator system, the transmission cooler ruptured while driving causing immediate loss of power and the engine to overheat. This malfunction also caused coolant and transmission oil to contaminate the engine compartment as well as the transmission. This is a major iengineering flaw and safety issue as I was on the interstate when it happened and was stranded on the side of the highway until help could be obtained.

For a month prior, there were intermittent incidents of the van shuddering and the rpm needle jumping upon ignition. Sometimes the van would have a hard time accelerating before jerking and driving normally. No issues before this started in late July and no indication when/where would occur. •September drove the van all day running errands. It drove normally. Filled up the gas tank (gulf gas station), then continued errands. About a half hour later, while at a stop sign, a notification appeared that the “traction control system has been turned off” and the check engine light came on. Tried to move through the stop sign, but the van would barely go. Applied the gas, but no results. Able to turn onto a side street and had to have it towed to Toyota of irving. The service advisor stated the issue was due due to bad gas and indicated the van needed to be flushed and the fuel injection system cleaned. Paid $725 for these repairs. •September started van in driveway. Shuddering and rpm needle jumping again. Drove normally. •September same as above. •September drove the van all day with no issues. Filled up with valero plus gas. As we pulled out of the gas station and sitting at the light, the traction control message and check engine light again appeared. The van would barely go to get us through the traffic light and into a nearby parking lot. Once we parked, the screen displayed the following message:"a malfunction in the electronic control of the engine, throttle, or automatic transmission has been detected. " had the vehicle towed to Toyota of irving. The service advisor called 2 days later to say they cannot detect any issues.

I my Sienna had its 12 volt battery depleted over night with no reason. After it was jump started, literally every single piece of equipment was malfunctioning and producing an alert (hybrid system, brake pressure, rcta, bsm, awd,tire pressure and so on). After several restarts of the engine (about 15 min after running engine), all systems went to normal except hybrid drive system, that still asked for maintenance and the tire pressure sensor was still on alert. However I drove the vehicle to a dealership in maine after the parking brake finally decided to get loose again. These guys told me, they had just the same problem with another 2022 Sienna a week before. However, they reseted the errors, and everything worked fine. They had no explanation why two Sienna in one week come to their lot with a depleted battery and as a consequence with a malfunctioning hybrid systen. That's very unsatisfying.

Was driving my Sienna down he highway, as I was passing someone I lightly accelerated and I heard a loud bang sound. Seconds later I see smoke coming out of the hood so I pull over, about 30 seconds before I pulled over the engine bursted into flames. When the vehicle came to a stop it would not unlock and me and my 2 kids were stuck in a burning vehicle, we barley made it out and my arm got burnt from it, this is the 4th time I’ve had a problem with the engine and 6th time the transmission has had problems. I’ve heard this happen on many other Siennas yet it’s not recalled….

The engine stalled, power steering frozen then engine shut off while driving in an intersection. Replaced new battery, dove home upon arrival the engine stalled again, power steering frozen and engine shut off again. I don’t know what’s going on.

I was driving my 2017 Sienna on 5/10/2022 and was approaching a roundabout. As I was going thru the roundabout, my van stalled. I coasted into a gas station. After a few minutes I notice smoke coming from under my hood. I popped the hood and noticed the smoke was coming from the air intake. We called aaa and they towed it to the dealership we bought it new from and had all services done at. The next day we authorized them to do a diognostic on it where they found a burnt airfilter and melted housing. Heiser Toyota in milwaukee WI has not repaired the van yet and we wanted to talk to Toyota customer service and your office to see what we should do. We called insurance and a claim has been started - not sure if they have inspected the van yet. It is available for you to inspect. All warning lights were on when it stalled. There was no power loss or any warning before it stalled.
