FUEL/PROPULSION SYSTEM
Hi, I’d like to report a serious issue with my 2018 Toyota Sienna related to the recent fuel system recall. Since the repair, the vehicle has leaked all of its gasoline not once, but three separate times. One of those times, my family was inside the vehicle, and the smell of gas was overwhelming. The car wouldn’t start, and it was clearly an unsafe situation. Now the dealership is charging me $1,400 to replace the fuel pressure hose and clamp, which, after thorough research and review, appears to be directly related to the process they followed when replacing the recalled fuel pump. I’ve also tried contacting the service manager, but I haven’t received a call back. That’s why I’m now requesting that Toyota open a formal case to investigate this properly. I believe this repair should be covered, and I’m asking for support from Toyota directly.

VISIBILITY:REARVIEW MIRRORS/DEVICES:EXTERIOR
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.

LATCHES/LOCKS/LINKAGES
The contact owns a 2022 Toyota Sienna Hybrid. The contact stated while closing the sliding door, there was no safety mechanism to stop the door from closing on a person or object. The contact stated that approximately four months ago, her eldest son was entering the vehicle, he became stuck between the door and the door frame. The contact stated that on a later date while her youngest son was entering the vehicle, the close button was depressed on the outside of the vehicle, and without any mechanism to prevent premature closure, his arm became stuck between the door frame and the door while the contact was inside the residence retrieving additional items to take the children to school. The contact stated that her older daughter was able to remove him from the vehicle. The contact stated that her son sustained injuries to his arm and had marks all over his arm where it was stuck between the door and door frame. There was no medical attention provided but an ice pack was placed on the part of the arm that was stuck in the door.

UNKNOWN OR OTHER
I bought this vehicle brand new. I quickly realized that both rollers on the sliding doors were causing excessive noise, which I found out that many other owners have complained as well, when closing & opening. This is because of a poor assembly from Toyota as the rollers are not machined prefect painted & are either oversprayed or less sprayed causing gaps on the rollers. These gaps or uneven paints causes excessive noise when rollers are moved on their track. There are several new Sienna owners who are waiting to have this issue fixed as the parts are backordered. I had to make total of 4 trips to my local dealership to have the issue fixed. I can still hear a little bit of over excessive noise from one of the sliding doors. Toyota should immediately recall all the affected vehicle and have this issue fixed.

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA
I bought this van brand new. I quickly realized that the reverse camera view has some issues. I believe images are not clean and sharp, as it is supposed to, and has unreasonable amount of distortions. Cleaning the camera from outside didn't do anything. I also noticed that the bottom part of center blue alignment line is little bit to the right and not align with the top. I checked online and it appears that other owners are also suffering from this same issue. Toyota should recall all affected vehicle and fixed this issue as soon as possible as this is a major safety issue when backing up!

SERVICE BRAKES
When going down hill while braking, the brakes will release causing the car to lurch forward and then they grab again. It’s intermittent and Toyota has a TSB on it but the dealership with not fix it because they can’t duplicate the problem. It can cause people to take their foot off and of the brake pedal and trying to apply it again. Which can cause someone to rear end another car.

STRUCTURE:BODY:HATCHBACK/LIFTGATE:SUPPORT DEVICE/STRUT
The lift gate strut bent when I tried to close the rear door, then when I tried to open the door to see what the issue was, the strut exploded. The parts went flying and almost hit me in the face, I could feel the air on my cheek as it blew past me. The spring and metal parts inside the strut shot all the way across my cul de sac, and the noise it created sounded like a gunshot. My neighbors came out of their houses to see what happened because it was so loud. We have an appointment at the dealer tomorrow to get it looked at. If I was standing any closer the spring would have hit me in the face; my children luckily were in the car already, if it happened a minute earlier it could have hit them. I noticed after the fact that the gaps in the back door are uneven when it’s closed, and I wonder if the door is installed unevenly and that put pressure on one side more than the other causing the strut to break. I can’t take a picture of the broken strut because I am too afraid to open the rear door in case the other one explodes.

POWER TRAIN
We have started to experience the transmission whine at that is specified in Toyota's CSP ZJC documentation. We took our vehicle into our local Toyota Dealership Service Center and they confirmed that the whine was a transmission issue and that the only course of action to take would be to replace the transmission. Our vehicle was manufactured in the specified window (manufacture date 10/2016, manufacture data window from the program 7/2016-2/2018), it has the specified transmission model (UA80), we are within the coverage window stated in the support materials (within ten years of first use), we are experiencing the same transmission symptoms described in the program support materials (whining transmission noise), and we have been recommended by our local Toyota Service members to replace the transmission. From this information, it appears that we meet the criteria and are suffering the same issues as are referenced in the ZJC materials, but our VIN is not included in the program. I believe that is an error and the program should be expanded.

SERVICE BRAKES
In general the braking system on this vehicle is poor. The van does not seem to want to stop unless you apply a lot of pressure on the brake pedal. I have taken the vehicle to the dealership who explained to me that the braking operation is normal. I replied “so the poor brake design was intentional”. The dealer said the braking system takes a little while to get used to. I have contacted Toyota corporate 5 times to express my concern about the brakes. The customer service representatives say that they will pass my concerns along. I personally own 6 vehicles. The brakes on this Toyota are by far the worst. It is not even close. I do not feel like this vehicle is safe. This is a minivan that is used to move families around. I do not feel safe in this vehicle and most importantly I am worried every time my wife drives this vehicle that someone will slam on the brakes in front of her the van will not stop in time. Toyota is the world’s largest auto maker, they can and should produce a better braking system than what is available with this van. This is unacceptable with braking technology available at this time in automotive history. Their lack of response to my concerns in also disappointing. Thank you for hearing my concerns.
