The driver's side passenger door power cable broke. We had to turn off the power to all of the mechanical doors. There may have been a recall on this awhile back. The cable could be seen outside of the vehicle. We since have tucked it out of the way.

The spare tire, which is normally secured under the minivan, fell off while driving at approximately 40 mph. My son, who was driving the vehicle, heard a sudden loud noise from the underside of the vehicle. He looked in his rearview mirror and saw something in the middle of the road. He pulled over to inspect the vehicle, and noticed that the spare tire was gone, which he was able to retrieve. I brought the vehicle to a local Toyota dealer, who indicated I needed a new spare tire carrier (at a cost of $329.07), since the original unit had failed due to rust. The spare tire had never been used or removed from its manufactured mounting position since original purchase of the vehicle in 2014. There were no warning signs at any time prior to the incident that the spare tire might come loose from its mounted position. The safety issues associated with this incident are obvious, e.g., another vehicle striking the spare tire or loosing control to avoid the spare tire; the tire rolling and striking a person, another vehicle, or damaging property, etc.

On October 15th at approximately 3:30 pm (ct) my 2014 Toyota Sienna was parked in my driveway with the engine on, unattended, when it moved forward up the slight incline of my driveway, struck another vehicle that was parked in the garage and kept moving forward until it struck the front wall of the garage. Prior to the accident, I had reversed the van out of the garage and left the van ignition on and in park as I exited. I know for certain that the van was in the park position since the automatic locks let me exit the vehicle without having to manually unlock them and the alarms did not sound as I exited. The van also did not roll forward ir backward as I exited. I then walked in front of the van to enter my house through the garage. I was in the house for less than 5 minutes when I heard the loud crash of the van striking the garage wall. My Toyota Sienna was manufactured on June 6, 2014. After the accident I discovered there is an active recall (recall: Transmission shift cable/rollaway/FMVSS 102) for an issue that causes rollaways effecting cars manufactured between June 17, 2014 through June 24, 2014. I took my van to Toyota expecting my issue to be related to this recall. Toyota had the black box inspected and the transmission inspected and determined they were not liable since they were not able to replicate the issue and did not find any defects. When I took my car in originally the technician stated that there was not a good way to determine if the shift cable was defective and they were simply replacing the part as part of the recall, which my car did not qualify for since it was manufactured 11 days prior. A car should never move itself from the park position and something has to be faulty with the car in order for it to do so.

While stationary, the sliding door cable snapped while it was automatically opening and has impeded the sliding door to even open manually which leads to safety concerns as the door will not open up as the cable impedes in its way.

With the car in park and attempting to open the driver side sliding door, it refuses to open and stops abruptly during the slide only opening a few inches (not enough to render the opening usable) because the fuel door is not sufficiently closed to depress the push button that tells the van's system that the fuel door is fully shut. Thus the sliding door stops abruptly (as programmed) to avoid a collision with an open fuel door. However, that is not the case here. Upon further inspection it is noticed that the spring on the push button has such a severe stiffness that the fuel door's hinge system was not designed durable enough to compensate for the outward load exerted by the push button when the fuel door is closed and locked. For this reason, the fuel door hinge, over time, experiences a fatigue failure at the top of the hinge only. That is to say, the lower half of the hinge remains connected and operable while the top half of the hinge shears in twain. Now sheared, the fuel door is pushed freely away by the push button and the top forward most corner of the fuel door protrudes past the van's profile by half an inch or more. It is the failure of the fuel door hinge, created by the overdesign of the spring on the push button, that allows the door to not open properly despite the driver doing everything to keep the path of the door clear. Unfortunately, for embarking, this renders the sliding access point as difficult as you have to manually push against the fuel door when opening the sliding door until it halfway open. For disembarking this is the safety hazard, as there is no way to "rig" the system to operate from the inside and during emergency egress from the vehicle. If the passenger door is blocked or broken as the result of a hazard or crash, occupants in the rear of the vehicle can become trapped inside being forced to climb into the front seat or trunk

Sliding door issues - this is a follow up to previous complaints regarding issues I was having with getting the sliding doors on my 2014 Toyota Sienna fixed. The original recall did not solve the problem, the two warranty enhancements did not solve the problem, and it was finally determined that the sliding door hinges were the problem. I reached out to Toyota motor corporation after having no luck dealing with the local dealership and the gentlemen I worked with on my complaint was extremely helpful. We were able to get the hinges replaced on both sliding doors for $140 vs $758 and they are now working as they should.

This is a follow up to an earlier complaint regarding the sliding doors on my 2014 Toyota Sienna not closing. Their was a recall and warranty extensions issued. I had the recall issue addressed, which did not fix the problem, so after several months I was finally able to get the local Toyota dealer to take care of the warranty extensions addressed, and still not fixed. I was then told that until I get the hinges on these doors replaced the problem will continue. So, after all that, I am told that the hinges are the problem! the warranty coverage program I purchased does not cover the hinges (I purchased one of the best warranties) and the hinges are going to cost me $758. Shouldn't their be a recall on the hinges to address this problem? I sure am hoping so.

Started having issues with left & right sliding doors not closing on 2014 Toyota Sienna roughly 18 months after purchase. Later received a recall notice for the instrument panel junction block and new wire harnesses as well as warranty enhancements for sliding door front and rear lock assemblies. Brought in to white river Toyota in white river junction, vt for repair and was told that all that could be done was the recall item as they could not duplicate the sliding door issue not closing. Have continued to have this problem and have had to close doors manually. Brought in again to have repaired approximately a year later and was led to believe the warranty enhancement repairs would be done only to be told that they needed to order the parts and that the technician recommended the replacement of both sliding door hinges at a cost of $758. The extracare warranty that I had purchased when I bought the vehicle will not cover the hinges as these were not covered when the warranty was purchased. This vehicle is a 2014 and I started having these issues within two years of purchase. Why isn't Toyota stepping up to the plate and fixing these issues" these problems are well documented and Toyota supposedly prides themselves on customer satisfaction. Are they waiting until these doors can't be closed at all and/or fall off before they will be forced to fix" I will never purchase another Toyota or recommend a Toyota for the simple fact that customer satisfaction and safety does not appear to be their #1 priority.

For about 3 weeks my spouse noticed a musty smell inside the van and then noticed that the entire cabin carpet was soaking wet. On 09/14/18, I took the van to team Toyota in glen mills, pa and had the ac lines drained. The carpet was still getting wet after having this service done. On 10/09/18, I took our van back to team Toyota to have a company called the "water doctor" to diagnose the water leak problem. Team Toyota advised that the "water doctor" discovered the leak was coming from below the front windshield cowl. The "water doctor" applied a sealant to the effected area. Team Toyota replaced the padding and deodorized the cabin area. My bill to have this repaired was $551.20.

Recently, at approximately 80,000 miles, the upper hinge of the fuel filler door (the door covering the gas tank access) failed. This appears to have been caused by pressure exerted on the door by the safety switch governing the driver side sliding passenger door. This is a known issue, documented here: www.siennachat.com/forum/67-problems-maintenance-repair-gen-3/19274-fuel-filler-door-hinge-broke-anyone-else-have-happen.html#. I brought my van to my local dealer repair facility, novato Toyota, at approximately 81,000 miles and was told that the cost to repair would be around $380. I was told that neither Toyota nor the company providing my extended warranty would cover it. In addition to being caused by a mechanical design defect that could not have been foreseen, it causes a safety issue, as it will prevent opening of the rear passenger door when the switch is activated. Photo attached is not my vehicle, but a photo found online of the same issue.

My Sienna is 3.5 years old and only has 33,178 miles on it, which means it is out of warranty for years, and it needs a new radiator due to engine coolant leak. Oil changes and maintenance has been normally done at our local dealership. Seems odd for a radiator to go to soon so money is out of pocket to fix.

  • 52,000 miles
At right around 50,000 miles, the cable on one of my power sliding doors snapped. This I have already filed a complaint for. But then at around 52,000 miles, the cable on the other power sliding door snapped. Now both doors have to be used manually, which would be fine except for the doors are so incredibly heavy that if the car is on any sort of hill, my children can barely get the doors open because they are so heavy. On top of that, they don't always lock open when being used manually. A child would easily be crushed by these doors if they lost control of them or if another child let go of the door. This is an incredibly dangerous hazard that Toyota should fix.

The cable for one of my power sliding doors snapped. The door is then difficult to use, and does not lock in the open position. Those doors are too dangerous to not lock in when in the open position. This is a vehicle designed for children who would be severely injured if the door slid shut on them. The vehicle was parked and one of my daughters was opening the door when the cable snapped. The vehicle only has 50,000 miles on it. This is a car designed for children! so for the door to be suddenly unsafe when the car only has 50,000 miles on it seems unacceptable to me.

My car was stopped at red light in uphill and tried to take my foot off brake to go on green light, my car started rolling backward badly in drive mode. It was about 20 degree incline. I believe that all automatic transmission should not roll backward. I brouht it up to one of the Toyota service advisor when I took my car there for service, he said that is normal when car is in drive mode. I believe this is a critical safety issue. It was rolled back about 1 foot before I hit the gas pedal. I almost got an accident. Please investigate this. Thanks.
