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)

Nonstop flickering of cruise control illumination at night. Flickering is independent of speed, steering wheel position. Very distracting while driving.

The cruise control backlighting on the "control stalk" blinks/flashes erratically in the driver's peripheral vision. This is quite dangerous and distracting. This happens at all speeds and driving conditions but seems to be worse when having to turn the steering wheel more (I.e. A parking lot vs. Changing lanes on the highway).

Nonstop flickering of cruise control illumination at night. Flickering is independent of speed, steering wheel position. Very distracting while driving. Dealer says no fix available. Toyota corp notified - case opened.. No fix available. Buyer beware.

While driving on the nys thruway with the cruise control activated my van came to an abrupt stop on the thruway. There were no vehicles in close proximity to my van that would have activated the radar cruise or the autonomous emergency braking system. After the abrupt stop all the lights on the dash were lit up ie: brake, ABS, pcs, slip indicator light, and master warning light. When I reached my destination I was unable to open the doors of my vehicle. Someone tried to open the doors from the outside of the vehicle and they were unable to open them as well. I brought it to the local toyota dealer and they could find nothing wrong. The above lights have lit up on several occasions however the dealer could find nothing wrong. There has been a previous complaint for the same behavior on 6/6/15 reported to toyota for the same make and model as mine a toyota sienna premium and they have not been able to get toyota to act on it.

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.
