Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

CarComplaints.com Notes: Toyota says the 2015 Sienna has been redesigned with "more swagger." Let's hope it's also been redesigned with less seat noise.

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

While traveling, our 2015 AWD Toyota Sienna with 8K miles caught fire and was a total loss. The vehicle was traveling 45 mph on rt 102 North in southwest harbor, me by the echo lake national park entrance, when we noticed white/brown smoke in the rear view mirror. We had only been on the road for about 5 minutes. We pulled over and turned the car off. When the car came to a stop, black smoke came into the cabin and everyone evacuated. During the evacuation, we noticed flames coming from the front engine compartment as well as the underside of the vehicle. By the time the southwest harbor police and fire reached us, the vehicle was completely engulfed in flames. The vehicle had been driving well the entire trip. The vehicle had been serviced once at 5K miles. It is unknown exactly what caused the fire. We've filed an insurance claim with arbella insurance. The claim number is 033734081. Also the national park service Ranger [xxx] filed a report [xxx] about the incident.

My 11-year old son got out of the front passenger side of our staitionary minivan (in park but running), for me to drop him off for a cello lesson. He opened the rear passenger side sliding door to get his cello out. It wasnt opening easily, so I almost simultaneously pushed the button above me on the console. At that point the door started to close on him. It did not stop closing and was pressing him into the door frame. I didn't realize what was happening, and he was too shocked to scream. He was trying to stop it from closing on him, but it kept closing. I expected that the door would automatically sense a blockage, stop and open back. He was only ok because he was strong enough to press back, but his hip was very bruised. I finally realized that the door wasn't opening, and pressed the button again above me and the door stopped. It stripped the wires in the door, and the automatic door is now broken. The electrical or sensing system in this door is faulty.

The speedometer & tachometer on the model has a dark background with small numbers and doesn't illuminate in the auto position. If the sun is bright with glare off other vehicles and you have to wear sun glasses they illuminate but the are either difficult to see or impossible. This is a safety concern, in my opinion, while you vehicle is in motion.

There was no accident or incident. I'm trying to avoid a potential accident by being forced to see the gauges that are essentially invisible while driving. The standard tachometer and speedometer gauges in this car have dark faces. When driving on a sunny day with sunglasses on, they are almost impossible to see. This is a definite safety issue as one has to look very closely and longer than normal to be able to see one's speed. The optional SE model has these instruments with white faces and would be much easier to see in bright conditions. I feel Toyota should retro-fit properly designed gauges to avoid accidents that may occur because the driver was distracted by trying to see the dark gauges!

The cruise-control stalk light has started to flicker at night. It's very distracting and hard to not keep looking down at it while driving.

Sienna 6-cyl

  • 9,203 miles
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.
