2017 Toyota Sienna electrical problems

Filed Jul 8, 2026 · Electrical · GA

power sliding door (behind front passenger) does not fully engage arresting hook and tends to immediately return to open position and after hitting the button again starts welling. It started about eight months ago. Now it isn’t connected at all, I just open or close it and it slides but don’t try to open it first if it’s locked or the alarm blares. I may have pulled or pushed it too many times trying to open or close it so I could drive the car. Looks like others have had the same issue with their driver side passenger door too.

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.

Purchased used vehicle from a Toyota Dealership on or about March 27, 2021. The dashboard illumination on the 2017 Toyota Sienna only appears to operate when the vehicle is turned on AND the front headlight selector is moved to the on or automatic mode. I do not believe it is a standard feature for any vehicle to NOT illuminate the dashboard without the headlights being turned on. Issue: With no illumination of the tachometer and speedometer these items are nearly impossible to see. That naturally forces the human eye to remain looking down slightly longer than normal which can possibly result in an accident. If it is a sunny day with no need for headlights this issue is now exacerbated because the bright sunlight often causes drivers to wear tinted or dark sunglasses rendering the dashboard nearly 100% black. So, my question is a simple one: On the 2017 Toyota Sienna, with the standard feature set included as indicated under VIN - [XXX], should the dashboard lights illuminating the tachometer and speedometer areas turn on immediately and automatically when the vehicle is started? On the vehicle, the dashboard lighting only turn on when the headlights are turned on or set in the auto-headlight mode…both of which are not my choice. I want see my dashboard data automatically and without having to drive with my headlights turned on. This is a poor dashboard visibility standard for this make, model and year Sienna.

Today I had a crash and luckily walked away. I went down an embankment at speed into trees where the vehicle rolled and struck trees head on. All the vehicle airbags deployed and vehicle came to rest on the drivers side. Although there was electrical power and the engine still running none of the right side doors would open and neither would the rear hatch which was clear of obstruction! Had there been a fire I wouldn't be making this report! Doors need to be operable regardless of situation when none of them are jammed from an accident!

Wire harness section which controls the Parking Collision Warning and Rear Cross Traffic Warning is frayed, causing failure. This failure was determined by the dealer to be caused by mud packing into the rear bumper cavity. Dealer wanted over $1,000 to fix. Denied warranty, due to the cause being "an outside influence". There is no way to effectively wash the inside of the bumper without removing the bumper. If I pay for a new wire harness, the issue will re-occur. This poses an elevated risk to my family and any occupants of the vehicle, as key safety features must be disabled.

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.

My power doors open and won’t close. It takes multiple times to finally get them to close.

On October 15, 2021 at 2 pm I drove into the driveway of a friend. I turned to the right of the driveway on her grass so I could backup and face the road. I’ve done this many times in the past. On this day as I put my foot on the break the van accelerated at a very very high speed. The van was out of my control at this point. I do not know how fast because this all happened in seconds. I was heading straight to their privacy wood fence only feet away. Approximately 20 feet. I don’t recall breaking again but turned the wheel to the right trying to avoid the fence. I hit the fence at a high speed damaged the left bumper and scraped the drivers side of the door. The next second I attempt to break again so I could back out of this when the van continued to accelerate at high speed going straight toward the house only a few feet away. I attempted to avoid the house and hit the right bumper hard at a high speed on the corner of the house. At this point the acceleration stopped and I was able to backup and turn the car around and finally turn the car off. There is major damage to the van and some to the fence and house. I was very upset and in shock and some soreness the next day but thankfully no one was hurt. This is a very small yard area that this took place at. I am still in shock and extremely confused as to why this happened. I do know without question my foot was not in the accelerator. The van is presently in the body shop. I would like to mention I have a clean record at the age of 64 I have never had an accident and/or speeding ticket in my life. This truly was not human error. I’m a very experienced driver. If it was human error the van should have stopped at the first point of impact on the fence, but did not. It continued to accelerate at a fast speed after hitting the fence hard. The van paused but continued to accelerate at this point when I hit the break again and it went toward the right straight for their house.

When vehicle is park on an angle (with Front section lower than the back) power sliding door (behind front passenger) does not fully engages arresting hook and tends to immediately return to close position sometimes hitting passengers trying to enter or exit the vehicle. Vehicle was taken to dealer for check up but dealer claims to have been unable to replicate issue, possibly due to not placing vehicle on an angle. No warning lamps or lights indicate any issue with the vehicle passenger door(s).

The sliding doors will open on their own.
