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

When pulling into a parking space, the care reved and lunged forward, approximately 5 feet while the foot was on the brake. Happened twice, when turning right into parking space. Called dealer about incident and then took van into dealer next day. They contact Toyota (case #152470163). Toyota informed dealer that this was not that uncommon with Sienna vans. If someone had been in front of the vehicle at the time of the first incident they would have been injured. If I had been parking in my garage I would have damaged the house. Toyota indicate there was not a repair and that one was not needed and told dealer to release the vehicle to customer (quote). The dealer thought it was the computer and that it reved the motor automatically due to using ac. We do not understand why a computer can not be programmed to make sure this does not happen - we no longer feel safe in the vehicle.

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.
