36 Engine And Engine Cooling problem of the 2022 Toyota Sienna

Failure Date: 04/13/2022

During heavy rain exhaust system become dislodged and fell to the road, only hanging on by the engine connection. We had the vehicle towed to the dealership only to be told that is not a warranty issue. They did reinstall it in the rubber brackets. Due to my persistence a warranty claim was opened. There claim was that it hit something as there were marks across the muffler however those were made by dragging on the road until vehicle could be driven off the road. Knowing it was most likely water pressure from the water on the road that lifted the exhaust up and out of the rubber brackets, I wanted this documented. Although if the exhaust system had completely broken off from the engine it would have not hurt our vehicle occupants, any vehicles behind could have been hit.

40 Engine And Engine Cooling problem of the 2014 Toyota Sienna

Failure Date: 01/29/2022

The Toyota 2gr-fe 3. 5l v6 engine have a verry comoon complaint of blown head gasket under 100k miles. I own a 2014 sinenna and currently experiencing same issue at 89k miles. I looked online and found that so many people had the same issue and there was no action from the side of the company, they just waited for the 60k miles/5 year to be over so that they can deny the claim. The funny thing is that my vehicles's previous owner purchased an extended warranty which is still valid till September 2022 and the company doesn't want to honor it. With this issue in mind I cannot take my vehicle for a long with my family, it puts life of my family at risk.

42 Engine And Engine Cooling problem of the 2017 Toyota Sienna

Failure Date: 10/14/2021

On 10/14/2021, as my wife was pulling into our attached garage, the vehicle suddenly accelerated, hitting a metal storage shelf located at the back wall of the garage. The impact of the crash caused the vehicle and the shelf to extensively damage the dry wall of that area of the garage, as well as to damage the pedestal supporting the house water heater, which resulted in the water heater detaching away from the wall and being destroyed. There was, of course, also major damage to the front bumper area of the vehicle. It is my contention that the cause of the accident lies in some component of the vehicle acceleration system. I believe this to be true because of two prior incidents which occurred within the month before this happened. On 09/16/2021, I was driving this vehicle and wanted to make a u-turn. I was traveling at approximately 10 mph, but as I began the turn, suddenly, the vehicle accelerated to about 25 mph, even though my foot was off the accelerator. My wife and granddaughter were in the vehicle at the time and both expressed alarm, somehow thinking I had purposely made this maneuver, which I assured them that I had not. Then, approximately 7-10 days later (I am unsure of the date), I was driving, alone, in this vehicle and went to make a left-hand turn. The vehicle again accelerated, even though I had removed my foot from the accelerator pedal and was applying the brakes. I estimate that as I began the turn, my speed was 10-15 mph, but the vehicle accelerated to 25-30 mph. I dismissed both of these prior incidents as not too important and attributed them to some unknown anomaly on the road. However, after the latest incident involving the damage to my garage and vehicle, research showed that several Toyota models and specifically the Sienna have had similar issues in the past. I am reporting this incident to Toyota for their evaluation, but wanted to make your agency aware, also.

43 Engine And Engine Cooling problem of the 2013 Toyota Sienna

Failure Date: 08/16/2021

This is to advise you of a safety issue with our 2013 Toyota Sienna xle minivan having a v6 (3. 5l) engine. Our vehicle currently has 118,169 miles on it and has been well maintained. This vehicle was purchased new and is operated primarily in florida where we live. Over the last 6 - 10 months on three occasions our Sienna minivan suddenly lurched forward as the engine revved up. On all three occasions, I had to take quick action and with significant force press the brake pedal as well as place the minivan in neutral and then into park in order to stop our minivan from surging forward and hitting the car in front of me. On all three occasions, my right foot was on the brake pedal when this occurred and on two of the three occasions, our minivan was slowly accelerating from either a stopped position or a very low speed (5 mph or less). On one of the occasions I was approaching an intersection with a stop sign and our minivan was decelerating to a stop when the engine revved up and the minivan surged forward. This occurred as our minivan was going approximately 5 - 10 mph. There were no warning lamps, messages, or other symptoms prior to any of these incidents. I have reported this condition to our local Toyota dealer but they said they could not duplicate the issue during their test drive. This is a serious safety condition and one that could result in a serious accident with injuries particularly if the driver is not quick to react to this unexpected condition.

54 Engine And Engine Cooling problem of the 2015 Toyota Sienna

Failure Date: 01/20/2020

When the car is at idle speed, such as waiting for traffic to clear for a left turn, the car will just die without warning. It will usually restart right away, but this has nearly caused a collision. The dealership in bellevue, wa says that's a normal thing if the car isn't properly maintained. I have brought the car to that dealership for all but one of the maintenance intervals, and the only other time was for maintenance when we were in ohio. Having the throttle body cleaned is not on the routine maintenance schedule. When the car does die there are no codes or other symbols that come up on the display, other than to say that the car died.

I am paying $600 a month for a car I can't use and can't sell.

56 Engine And Engine Cooling problem of the 2016 Toyota Sienna

Failure Date: 12/10/2019

Our 2016 Toyota Sienna spontaneously caught fire while parked in our driveway after returning from a short drive. After pulling into our driveway and shutting off the ignition, my wife smelled smoke as she was exiting the parked vehicle. This smoke intensified and quickly accelerated becoming an engine compartment fire. She called for me & then called 911; but in the brief moments it took me to grab a fire extinguisher, the fire further intensified with sizable flames erupting out from around the hood, front grill & underneath the vehicle. I used up 2 fire extinguishers without any significant effect. I did not have any protective safety gear so after hearing several small explosions coming from under the hood & fearing more exposure to noxious fumes, I decided to abandon my attempts to extinguish the fire. The fire dept. Arrived within a few minutes and were able to put the fire out; however, the fire progressed through the initial attack and entered the passenger compartment causing severe damage to the entire vehicle (see attached photos). The Sienna is completely destroyed. Fortunately, there were no injuries. I have been made aware of multiple incidents of engine fires in Toyota Siennas in this & other closely related model years (2014-2017). See: NHTSA id number: 11010601. I can also supply you with some additional media accounts of other Toyota Sienna engine fire reports. Our Sienna was routinely maintained as per manufacturer's recommendations & was last serviced on 9/13/2019 (see attached service receipt). The vehicle had approx. 35k miles on it & exhibited no prior signs of trouble, change in performance or warning indicator lights. We did have an unresolved problem with automatic side doors not operating properly after a recall repair; however, the local Toyota dealer service dept. Could not identify a problem after multiple service complaints.

57 Engine And Engine Cooling problem of the 2005 Toyota Sienna

Failure Date: 11/01/2019

The traction control system is activating improperly. The vehicle's anti-slip indicator warning light illuminates; an alarm sounds; the abs system activates; and the vehicle sometimes loses power. This happens on dry roads, most commonly either going downhill or else on a curve, even a mild one. This happens above 20 mph. When it happens, the combination of alerts and sensations are very startling to the driver, creating a dangerous situation. It has occurred while trying to accelerate to merge onto a highway. This was exceptionally dangerous as the vehicle began losing power and vehicles behind us almost hit us from behind as we were slowing instead of increasing speed. From my internet searches (including NHTSA complaints), this appears to be a recurring issue with this make/model/year range. This has been happening for the past 3 months. Our vehicle has approximately 135,000 miles on the odometer.

58 Engine And Engine Cooling problem of the 2019 Toyota Sienna

Failure Date: 10/17/2019

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.

59 Engine And Engine Cooling problem of the 2015 Toyota Sienna

Failure Date: 10/09/2019

My Sienna van sometimes responds very late to acceleration. This becomes a problem on highways specifically during the merging. Acceleration paddle has to be pressed very hard, for first few seconds there is no response from engine then latter it suddenly accelerates. This makes you miss judge the time required to merge on highways and can cause accidents. This has been happening since few months. I am providing tentative date below.

60 Engine And Engine Cooling problem of the 2019 Toyota Sienna

Failure Date: 09/28/2019

I pulled onto a highway and reaching about 25 mph the 2019 Sienna hesitated for at least 10 seconds as if it was not getting gas. I pressed the gas wanting to get out of the way of traffic and it jumped slightly but would not go. Then it kicked in with a few hesitations and took off. Another 100' or so, it did it again. Prior to this I had already brought it to Toyota complaining that there is a hesitation when the van is not warmed up yet between 20-40 mph. It is only slight, but noticeable and feels like it is not getting gas. The van does this every time after it has been sitting long enough to cool down. The long hesitation only happened twice so far (dangerous enough!), there have been a few shorter ones, and then there is the every time slight hesitation. Toyota has told me nothing shows in their diagnostics and they do not know what is wrong. They tried cutting the power to the computer to reset the memory, but this did not change anything.

67 Engine And Engine Cooling problem of the 2014 Toyota Sienna

Failure Date: 12/13/2018

Vehicle stopped abruptly with a shake while reducing speed at a traffic signal. I was in the middle of the road. A mild burning smell came out from the hood. The car was serviced one month back and as part of it they did 128 point( do not remember exact number ) and all reported issues were fixed. Around $1000/- was spent on the car. Since battery was just 1 year old, I did not expect a problem with the battery as well. Still I switched off all lights and tried to restart. There was no further response from the vehicle. I was blocking traffic from behind and police came to control traffic. Only option was to tow the vehicle. I took it to the same Toyota authorized service center where I did the previous service ( I had purchased the car from the same dealer ). Next day Toyota service staff called me and asked details of what happened. By evening they said that some spring break in cylinder 4 which clogged at some other part within the engine. In the process, there are scratches in other parts and the engine oil was filled with metal parts. Senior technician said this is a major issue and they have invited Toyota field engineer to come and inspect the engine and associated issues. Preliminary assessment is that the engine might need a replacement as changing few parts may not be sufficient to keep the vehicle safe back on street. Incident happened in city street and when the speed was lowered to 20. Today is Monday, but Toyota dealer who is doing the service has not updated me yet with the magnitude of complete problem nor the time they need. I am heart broken to hear that the rough order magnitude cost to fix the car is between $18k to $20k.
