Air BagsJun 2026 · ODI 11745526Details +

We had our van parked on a driveway with a front facing slope, we had hard rains went we where going away there was water coming out of the seat belt on the passenger side and the panel above the window was stained down to the window support where the air bag is. I've been reading reports as far back as 2008 we have a 2020, went taken to the dealer they want 1000 to 2700 to remove the head liner and try to fine the problem, which what was reported didn't help. The dealer recommended to not park with the front of the van facing down hill if rain is forecast, my problem is that Toyota has not been required to fix the leaks. I'm calling my local dealership tomorrow about are leak.

My Toyota sienna is a 2020, has 83,000 miles and has recently been squealing when I accelerate. I took the van to a local body shop and they said it seems to be my transmission. I called Toyota immediately and they knew that the transmissions were faulty and that they would try to work with Toyota to get it fixed. There is no way I can pay 9k for a new transmissions because they put in faulty ones.

Power TrainApr 2026 · ODI 11733827Details +

The vehicle is a 2020 Toyota Sienna. While driving, the engine suddenly shut off without warning, creating a dangerous situation and loss of power. This occurred while transporting children, increasing the safety risk. A mechanic inspected the vehicle and diagnosed a failure of the low-pressure fuel pump. The problem appears intermittently — sometimes the vehicle runs normally, and other times it stalls or loses power. The check engine light has turned on and off. This issue matches the known defect related to the Denso fuel pump recall affecting many Toyota vehicles from similar model years. However, my VIN is not included in the recall. This is a serious safety concern because the engine can shut off unexpectedly while driving, which could lead to an accident. I believe this vehicle may have the same defective component as those included in the recall, even though it is not currently listed. The issue has been confirmed by an independent mechanic and the vehicle is available for inspection if needed.

The power sliding door assembly failed, and the driver side rear sliding door was bound shut, and could not be opened. Disabling the power door system did not resolve the issue. The cable for the power door mechanism was hanging below the rear vent windows; but for some reason the door still would not open. I ultimately with a lot of gentle force was able to get the door open enough to see the retract side of the cable was bound up, and was able to cut it with wire cutters, and ultimately get the door to work normally as a non-powered manual sliding door. Since the original NHTSA BULLITIN on this was published in 6/2019 before my 2020 Sienna was manufactured, and Toyota did not change the mechanism until the 2021 model redesign, I believe that RECALL should be extend to all 2019 and 2020 vehicles. This seems dangerous that the door does not default to manual operation in error.

"I've owned the vehicle for five years, and recently I started hearing a whining noise coming from the transmission. After doing some research, I discovered that I'm not alone in experiencing this issue. The dealer told me that the transmission itself is the problem and recommended replacing the entire transmission. However, a second opinion suggested that this kind of noise isn't normal. I'm worried about safety because, although it's just a whine right now, I fear it could fail unexpectedly. I have a child in a wheelchair, and ensuring my vehicle's safety is very important to me."

In August of 2024, we noticed the drivers side rear view mirror had come loose from it's external housing and was only tethered by wiring that was for mirror movement, defrosting and blind spot awareness. In order for it to be safe to use, we had to duct tape it so that it would not move. Unfortunately, the mirror continues to loosen and has to be retaped frequently. We took it to our dealer (McGovern Toyota) in Portsmouth, NH 0n 23 September 2024 and were told that it could not be fixed but had to be replaced and were quoted an amount of $2025.29 .We were also told that the part was on national backorder and may take a few weeks to arrive. Due to the astonomical cost of replacement, I tried to find other solutions and contacted other dealers and body shops but was told it had to be replaced and could not be fixed. I brought the car into another dealer, nearby (Ira Toyota) in Saco, Maine and they also said it had to be replaced and quoted an amount of $1937.70.I asked them to order the part, which they too, said was in national backorder. I contacted our automobile insurance company (AMICA) who agreed to cover the part and labor and issued a check for $1,420.60. Every month, I would call the dealer and every month I was told that Toyota estimated a delivery within a month, but that month would come and go with no part. For the last several months, I have been in touch with TOYOTA and their "brand engagement advocate" named Julie has reviewed our concern and also has stated that the part will be available by the end of the months of February, March, April, May, June and now July. I have written emails to TOYOTA expressing my dissatisfaction and now have a vehicle which is unsafe to drive due to the instability of the mirror and a vehicle which will not pass inspection (according to the dealer). I feel TOYOTA is lying about the parts actual availability and being disingenuous to what was a loyal customer. I am at a loss what to do next.

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 15: 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 17: Started van in driveway. Shuddering and RPM needle jumping again. Drove normally. •September 21: Same as above. •September 25: 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.

DEAR TO WHO CONCERN THIS CASE, ON AUGUST 26, 2019, I PURCHASED A BRAND NEW CAR, SIENNA, TOYOTA 2020 FROM PRINCIPLE TOYOTA ON 7370 WINCHESTER RD, MEMPHIS, TENNESSEE 38125. I DISCOVERED THAT THERE ARE MAJOR ISSUES WITH THE CAR. I WAS GUARANTEED BY THE DEALER THAT THE CAR IS IN PERFECT WORKING CONDITION BEFORE PURCHASE. HOWEVER, AFTER DRIVING THE NEW CAR FOR FEW DAYS, THE KEY REMOTE STOPPED WORKING AND I REVISITED THE DEALERSHIP TO GET IT FIXED. I TALKED TO JIMMY ROCKER, ONE OF THE SALE ASSOCIATES, AND HE TRANSFERRED ME TO THE TOYOTA SERVICE CENTER. AFTER FEW MORE DAYS OF DRIVING THE CAR, MORE PROBLEMS EMERGED. THE CAR WARNING MONITOR INDICATED 'AWD SYSTEM MALFUNCTION 2WD MODE ENGAGED, CONTACT YOUR DEALER' AS WELL AS 'BRAKE OVERRIDE MALFUNCTION, VISIT YOUR DEALER'. NOT ONLY THE WARNINGS, THE CAR SUDDENLY STOPPED ON THE HIGHWAY. LUCKILY THERE WERE NO CARS BEHIND ME, OTHERWISE I WOULD HAVE BEEN INJURED. THE SECOND TIME I REVISITED THE DEALERSHIP, I ENCOUNTERED CHRIS THOMPSON, THE NEW CAR DIRECTOR AT PRINCIPLE TOYOTA. I SUGGESTED HIM TO INSPECT MY CAR AND FINDING A SOLUTION FOR IT. I HAVE TRIED TO EXPLAIN TO HIM HOW IT WAS DANGEROUS FOR ME AND MY FAMILY. I HAVE TWO KIDS WHO ARE DRIVING WITH ME AND IF THE SITUATION HAPPENED AGAIN, WE WOULD HAVE BEEN FATALLY INJURED. CHRIS DID NOT LISTEN TO MY STORY BUT INSTEAD TOLD ME THAT THE CAR DOES NOT BELONG TO HIM AND HE JUST WALKED AWAY IN FRONT OF OUR CONVERSATION. I WAS VERY DISAPPOINTED BECAUSE OF HIS INDIFFERENCE TOWARDS MY SITUATION AND THE TYPE OF CUSTOMER SERVICE I RECEIVED WAS NOT EXPECTED FROM A WELL-KNOWN COMPANY LIKE YOURS. TO ENSURE THE SAFETY OF KIDS AND MY FAMILY, I DEMAND A REPLACEMENT OF THE CAR AS WELL AS ANY COMPENSATION ASSOCIATED MY SPENT TIME AT THE DEALERSHIP. I HOPE THERE WILL BE A REASONABLE SOLUTION FOR MY CASE. BEST REGARDS, [XXX] REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *CC *TR
