VISIBILITY/WIPER
2 month after buying the car, in Jan i turned the car on and the windshield wipers didn't work. It was a snowy day and the salt and snow made it dangerous to drive. Before i had a chance to bring it to the dealer, after about 2 hours, the wipers started working. This happened again in April, i was driving on the highway and it was raining intermittently. . I was using the wipers, and suddenly they wouldn't turn on. I pulled into the first rest stop and forced the wipers up by hand and than it started working.

ELECTRICAL SYSTEM, EXTERIOR LIGHTING
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.

SERVICE BRAKES
While driving slowly into a parking slot, the brakes released and the vehicle surged over a parking block and into a sign. On a couple of time previously, I have encountered similar situations but never when parking at slow speed.

SERVICE BRAKES
When going down a parking ramp exit, my foot has slipped off the brake 3 time. When looking at the brake pedal it is smaller than most brake pedals. I don't know if anyone else has had this problem, but mandating a minimal size for brake pedal might help

STEERING
My wife let me know that when turning to the right (not an aggressive turn, but a normal turn from one lane to the next), the whole electrical system of the minivan would shut down and then come back on. I had a mechanic check it out and they say that this is due to the electrical steering system and will have to be replaced by the dealer. He was able to reproduce the same condition where he was able to get the minivan to lose power when changing lanes. He STRONGLY advised that we should have the vehicle towed to the dealer as he felt that it wasn't safe to drive due to this. I feel that this will end up causing a lot of crashes and also that this should be covered by the manufacturer under a recall.

FUEL/PROPULSION SYSTEM, ENGINE, POWER TRAIN
Car was recalled for fuel pump and I repaired in 8/2020 with approximately 11,190 miles. I had complained that car, since time of purchase and had 4662 miles when I insisted Toyota fix this, (hunted for gears, hesitated, lagged when accelerator pushed, and had poorer gas mileage than expected). The car now has 34,875 miles on it and is doing the same thing, hesitating, lunging between gears. Our mechanic confirmed this and stated worse when using a.c. Called Toyota Customer Service and they said the car was out of warranty for the pump repair, but perhaps not the power train, transmission, etc. Have not gotten back to me yet, but has not been one working day after spending 2.5 hours on the phone with them yesterday. This is a safety issue, I press on the gas to make a turn and it lags leaving me in traffic. My 2007 Sienna, which is still running for my daughter, never did this and has full power when called upon. Toyota needs to repair the entire fuel system, transmission, if they cannot fix this. There are no warning lights when this happens & it is happening more frequently. Dealership told me they could not put another pump on car and to contact Toyota Customer Service and gave me the number. When we had the car for about a month, dealership said we were just not used to driving a car with this type of transmission and car was low on oil, we added oil and dealership said we used the wrong type, but we figured some oil was better than no oil. We are boomers and have been driving cars for decades, with clutches and without and we know how to drive a vehicle.

ELECTRICAL SYSTEM
All interior dome/lights (door side lights, visor mirror lights, all overhead passenger lights, etc) not lighting up at all. Fuse in engine compartment is good. Vehicle has been at auto dealership where originally purchased. Safety concerns are that at night, unable to determine if there has been access by person or if person is actually in vehicle. Vehicle diagnoses was begun on 6/12/2023 and is still in process of issues. Received a call from the service representative on 6/19/2023 that water had accumulated under the fuse box in the engine compartment causing corrosion at the connection of the wire harness to the underside of the fuse box. Initially this caused the the internal lights to fail. There is much more corrosion occurring which will eventually cause a complete electrical failure and possible engine failure/fire. Current recommendation from service manager is to completely replace the wire harness at a cost of $7,000+. Insurance may or may not cover the cost of repair. The insurance adjuster is meeting today with the service manager. In my opinion, this is a serious defect in Toyota Sienna manufacturing, design and materials used.

AIR BAGS
A deer was struck on the driver to middle of the front of the van while traveling 75 mph on the highway. Caused significant enough damage that van was inoperable. What was concerning was the airbags did not deploy despite the significant force and high speed associated with this accident.

STEERING
Power steering light came on while driving causing the steering system to lose power suddenly. Almost got into an accident because I couldn't effectively turn the wheel. Mechanic inspected and found the steering motor was bad and that CPU needed to be replaced costing almost $4000 in repairs. Now my car is not driveable unless this is fixed. Car has only 140k miles. This is a VERY common problem with Toyota Siennas around these model years

POWER TRAIN
We had a "hybrid system malfunction" warning on the dashboard and the van slowed down to 20 mph on a climb. With the flow of traffic at 50mph on a two lane road and no shoulder to pull off, this cause a serious risk to us and other drivers. Stopping and starting the car several times did not cause the warning to go away and the owner's manual says to stop driving. There were no warning lights prior to this happening. The warning and the MIL came on at the same time as the van started slowing. The local dealer now has the van and are not able to exactly diagnose the problem. They are contacting the manufacturer. They said the warning is no longer on.

There is a problem with the lighting in the information dial. The handbook even says the gauges may be hard to read in daylight if any lights are on. The daylight driving lights are always on. This is even worst when headlights are on. Many states like Texas, New Mexico, Colorado, Utah, Nevada and California have roads where headlights are required at all hours. There is also much sunlight. The gauge is virtually impossible to read. This includes the tachometer, fuel gauges, engine alerts, low tire pressure, etc. I feel this can cause unsafe conditions by not being able to access the data or drivers having to lower their head trying to read the info. With todays LED technology why would they not put a usable lighting system on the gauges. It makes no sense at all. This was a design and manufacturing defect and should be corrected. It does have a brightness control switch but the above is while on maximum brightness setting.

VEHICLE SPEED CONTROL:ACCELERATOR PEDAL
The contact owns a 2019 Toyota Sienna. The contact stated that after he entered the vehicle, he depressed the brake pedal to start the vehicle. After the vehicle was started, he shifted into reverse(R) while the brake pedal remained depressed; however, the vehicle inadvertently accelerated without warning. In a desperate attempt to stop the vehicle from crashing into another vehicle, the contact shifted into drive(D) while the brake pedal remained depressed. The contact then stated that he applied pressure to the brake pedal to stop the vehicle from accelerating when the vehicle then jumped the curb and struck a garbage can. The contact then shifted into reverse(R) while the vehicle continued to accelerate to move away from the garbage can and then shifted in neutral(N). The contact then shifted back into park(P). The contact then stated that after he placed the vehicle in park, the inadvertent acceleration stopped. The contact shifted into drive(D) and the vehicle performed as designed; however, the contact was concerned for his safety and carefully drove the vehicle to his residence where the vehicle remained. The contact was unsure if any warning lights were illuminated. The vehicle was not diagnosed or repaired. Neither the dealer nor the manufacturer was notified of the failure. The failure mileage was approximately 45,750.

Door to gas tank fill breaking off. Very common problem noted online by several owners of this vehicle. If it does not close properly the engine will not start. As it begins to break at the hinge the door sticks out. I fear it will fall off one day. Dealer acknowledges this is a problem and knows there is no recall for it. I have seen other exact vans that the door has been removed completely.

VISIBILITY/WIPER
The entertainment screen is completely blocking the rear view when in use which is very dangerous when backing out. Also, I can’t see ambulances, fire trucks, police, etc. are coming behind me to pull over. This is a very serious safety issues for driver. Toyota said that I need to close the screen when this happens but it’s more dangerous for the driver to turn around to close the screen while driving.

STEERING, VEHICLE SPEED CONTROL, SERVICE BRAKES
I was driving on a dry road, going 70mph when my car began flashing the abs indicator and it began breaking and controlling my steering taking me into another lane. The car slowed my vehicle suddenly down to 60 mph and then went off like it never happened. I then had control. There was no reason for the car to do this. There was nothing in the road and luckily no one was to close to me or there would have been an accident. I almost over corrected due to the pulling of the steering and the breaking of the vehicle.

VEHICLE SPEED CONTROL, FUEL/PROPULSION SYSTEM, ENGINE
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.
