CarComplaints.com Notes: Toyota says the 2015 Sienna has been redesigned with "more swagger." Let's hope it's also been redesigned with less seat noise.

The dash was randomly freezing for about 5 minutes and then reset itself while driving. Once it reset itself, it went back to the default settings. It was at heart city Toyota multiple times for this problem. Each time they said that they could not get it to duplicate the problem. After dropping it off in April of 2017, the technician stated that he was able to duplicate the problem of the dash resetting. He did a software update and a hard-reset in order to try fixing it. Low and behold, two days later it happened again. After having it at heart city Toyota to have the problem with the cruise control light flickering, for the fifth time, fixed, I reported about the dash still having the problem of resetting itself. The manager of heart city Toyota told me at that point that I am not welcome back to their dealership. After contacting Toyota corporate about this, I was told that they are able to refuse service even with the warranty still present. They explained that I needed to take it to another Toyota dealership to have it diagnosed. So I contacted jordan Toyota and explained the situation. The service manager there informed me that if heart city Toyota was not able to diagnose the problem, then they were not going to start from scratch to diagnose the problem themselves. Three weeks later, while driving on a county road, the dash began to smoke and I pulled off of the road. When it began to smoke even more, I exited the vehicle and as I was getting as far away as I could I seen flames. I called 9-1-1 right away. By the time the fire department was able to get there and extinguish the fire, the van was destroyed. Which ended up being a total loss. All of which seemed to be due to an electrical fire in the dash. Luckily no one was hurt.

I have a 2015 Toyota Sienna xle with 35,800 miles. - (no specific conditions or driving styles) it is on it's third transmission (second replacement was at 29,800 miles) - newest recall on the side doors opening randomly. - (no specific conditions or driving styles. Happens completely randomly) cruise control lever light flickering. It was replaced three times now. It was just replaced the third time recently, so I'll see if it happens again. - (no specific conditions or driving styles. Happens completely randomly) dash randomly freezes for about 5 minutes and then resets to the default settings (it has happened seven times and continuing) and Toyota still cannot figure out the problem. - (while driving on a clear day on a city street) climate control shut off completely by itself without touching any buttons while driving. I was able to turn it back on, but it should not shut off without any action. - bad support bearing for axle on front passenger side (22,900 miles)

Their is a recall on the automatic sliding doors but Toyota has failed to correct the issue. The back doors unlatch automatically and have propelled open twice while I was driving my children!! I brought it into service and they told me they disabled the electronic opening function and I would have to open and close the doors manually until Toyota has permanent solution. It turns out they only pressed the power switch on my dash board and the doors continue to unlatch automatically. I will manually close the door and once driving I hear them trying to open. I've had to pull over and manually shut them tight but last night it flew open while I was driving without any warning that it had unlatched!! I'm paying $420 a month in a lease contract for a car that is unsafe. Toyota has failed to remedy the problem and dealers refuse to help me get out of this vehicle despite the fact that it is dangerous!

I stopped at a gas station and was parked with the car on, and I reached under my front passenger seat (manual seat) and received a 20 amp shock from one of the wires under the seat. Resulting in my dislocating my shoulder from the muscle spasms. Taking it into dealership tomorrow morning but after talking with them they dont have any idea what could have caused it.

Our daughter-in-law received an interim recall notice from Toyota yesterday. (safety recall G04). Apparently there is a possibility that the sliding door on the siena can come open while the van is in motion endangering the occupants. In this case, the occupants are our four year grandson, who has down syndrome, and three year old granddaughter. Toyota has declined to disclose whether there have been any accidents, injuries or deaths due to this defect. They are working on a fix but do not have a solution. Toyota's recommendation is to disengage the electronic doors. We viewed that additional cost option as a safety and convenience factor for our daughter-in-law. Surely, a company with the resources of Toyota could come up with a fix concurrently with this notice! minivans are generally driven by families with children.

While traveling, our 2015 AWD Toyota Sienna with 8K miles caught fire and was a total loss. The vehicle was traveling 45 mph on rt 102 North in southwest harbor, me by the echo lake national park entrance, when we noticed white/brown smoke in the rear view mirror. We had only been on the road for about 5 minutes. We pulled over and turned the car off. When the car came to a stop, black smoke came into the cabin and everyone evacuated. During the evacuation, we noticed flames coming from the front engine compartment as well as the underside of the vehicle. By the time the southwest harbor police and fire reached us, the vehicle was completely engulfed in flames. The vehicle had been driving well the entire trip. The vehicle had been serviced once at 5K miles. It is unknown exactly what caused the fire. We've filed an insurance claim with arbella insurance. The claim number is 033734081. Also the national park service Ranger [xxx] filed a report [xxx] about the incident.

My 11-year old son got out of the front passenger side of our staitionary minivan (in park but running), for me to drop him off for a cello lesson. He opened the rear passenger side sliding door to get his cello out. It wasnt opening easily, so I almost simultaneously pushed the button above me on the console. At that point the door started to close on him. It did not stop closing and was pressing him into the door frame. I didn't realize what was happening, and he was too shocked to scream. He was trying to stop it from closing on him, but it kept closing. I expected that the door would automatically sense a blockage, stop and open back. He was only ok because he was strong enough to press back, but his hip was very bruised. I finally realized that the door wasn't opening, and pressed the button again above me and the door stopped. It stripped the wires in the door, and the automatic door is now broken. The electrical or sensing system in this door is faulty.

The speedometer & tachometer on the model has a dark background with small numbers and doesn't illuminate in the auto position. If the sun is bright with glare off other vehicles and you have to wear sun glasses they illuminate but the are either difficult to see or impossible. This is a safety concern, in my opinion, while you vehicle is in motion.

There was no accident or incident. I'm trying to avoid a potential accident by being forced to see the gauges that are essentially invisible while driving. The standard tachometer and speedometer gauges in this car have dark faces. When driving on a sunny day with sunglasses on, they are almost impossible to see. This is a definite safety issue as one has to look very closely and longer than normal to be able to see one's speed. The optional SE model has these instruments with white faces and would be much easier to see in bright conditions. I feel Toyota should retro-fit properly designed gauges to avoid accidents that may occur because the driver was distracted by trying to see the dark gauges!

Sienna 6-cyl

  • 9,203 miles
There are multiple issues with this vehicle that cause/have caused safety concerns. During night time driving, the illuminated cruise control stalk will blink on and off intermittently. This has caused the driver to almost rear-end multiple cars as the flickering light takes the driver's eyes from the road. It was found that there is an intermittent high resistance connection with up to a 9 volt drop at times. Despite the steering column being switched out and the problem being fixed temporarily, the problem returns. There is something in this vehicle causing the wiring in the steering column to short out. Not only is the flickering light very distracting causing a safety issue with a possible vehicular accident, but the chance of the faulty wiring causing a fire is also a safety issue. Another issue that has been found with this vehicle involves the engine. While sitting at a stop light, the vehicle's RPM all of a sudden revved up and the entire engine began shaking. If the driver had not had their foot on the brake at the time this happened, this could have caused the driver to lose control of the vehicle, posing a safety issue.
