Tl* the contact owns a 2007 toyota sienna. The contact stated while stopped at traffic light, the vehicle stalled with the brake pedal depressed. Several warning lights illuminated on the instrument panel. The contact shifted the vehicle into neutral and coasted into a driveway. Upon inspection, the contact discovered that there was no oil in the engine. The contact refilled the oil however, the oil immediately leaked out the vehicle. A mechanic arrived on scene and replaced an oil hose. After the hose was replaced, the contact heard an abnormal knocking noise in the engine. The contact took the vehicle to several independent mechanics and was informed that the engine failed and needed to be replaced. The contact had the vehicle towed to suburban toyota of farmington hills (25000 haggerty rd, farmington hills, mi 48335) who confirmed there was an engine failure. The contact then had the vehicle towed to an independent mechanic where the engine was replaced. After the engine replacement, the contact experienced several transmission issues. The contact stated that while at a stop, the vehicle independently shifted in and out of gear without warning. Also, while in reverse, the vehicle coasted and jerked upon slight depression of the accelerator pedal. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 126,300.*dt

I was parallel parking, backing into a parking space on a long bridge in a downtown/busy area. When I tapped the accelerator lightly to back up, my van suddenly lurched back (in reverse), accelerating so quickly I felt like I was in a rocket ship being lifted into the air. My wheel was turned in preparation for backing into the space. At a breakneck speed, my van accelerated in reverse, lurching up a large concrete step (all 4 tires), squealing erratically. Then it continued across a wide sidewalk/pedestrian area, the bumper hitting the bridge, immediately knocking about 20 feet of a concrete railing from the bridge into the river below. Luckily, my wheels basically bounced off the bottom portion of the bridge, which was secured by a large concrete block at the base of the bridge. This all happened in about 1 second... It didn't take long. The first thing I tried when this happened was hit the brakes. They didn't move. It was like they were locked. As my van bounced forward after it bounced off the concrete block, I was able to get it into park. I am lucky there were no pedestrians on the bridge, as they would have been crushed immediately by the concrete, and thrown into the river below. I'm also incredibly fortunate my van didn't continue in reverse, plunging itself, and me, into the river. It was a harrowing experience and two weeks later, I am still not quite past it. I am a safe driver and this is my first "real" accident in 25+ years of driving. My van is totaled.

Engine/powertrain hesitates for 1-3 seconds when accelerating slowly, or accelerating quickly after slowing down such as when slowing down in an intersection, making a turn, or in slow traffic. Engine has piston slap for 3-5 minutes after a cold start in weather below 40 f. The slap becomes louder with colder temps. Shifting into gear with a cold engine can cause the vehicle to lurch due to high idle. Driver must have foot firmly on brake before shifting into gear. Problem diminishes if engine is allowed to warm for 45-60 seconds. When parking, the driver must keep the brake fully depressed, shift into park, pause 1-2 seconds before releasing brake. It seems there is a brief delay between gear lever being placed into park, and powertrain actually going into neural/park position. Releasing the brake too soon will allow vehicle to roll ahead 3-6 inches.

The transmission was doing what felt like "neutral drops" at low speeds, where I would shift into drive, get the "clunk" that I normally associate with the transmission dropping into first, then depress the gas slightly to start moving. The problem is that the engine would rev suddenly, and then catch first, which as you know, causes a sudden lurch of the entire vehicle since the engine had been revving just before it caught. It would also occasionally just "lose" the gear while driving at low speeds. On 6/12/2010 the transmission went out on me while I was driving home (with my family) on the fwy (north 5) from legoland. I have to across 5 lanes to get to the shoulder. I got the van brand new on 3/28/2007 (w/only3 miles on the van) from carson toyota, ca...I paid $28000 w/package3 (out the door price)...as of 6/12/2010 the van has under 14,000miles. The toyota dealer replaced the transmission with no charge (still under powertrain warranty). Transmissions aren't supposed to go out that quickly, it definitely seems to be a quality control issue. Under 14,000 miles there has been no service due so it's not a matter of missing scheduled maintenance. This is obviously a very valid safety concern.

I was parking my vehicle in the bixby hospital parking lot. I pulled into a space directly across from a vehicle, and put my foot on the brake. As I was putting my 2007 toyota in park the car lurched forward as if someone was pressing hard on the accelerator. The force was so hard that I hit a pole and then into the car in from of me, pushing the other car back about three feet into a pedestrian..

2007 sienna, hesitates after re-accelerating between 5 to 10 MPH. Acceleration pressed but car does not move for 1 or 2 second. Took to dealer 3 time and also talked to toyota hq (dealer did find problem but hq said not to put anything in report saying there is a problem) they just saying nothing can be done to car right now a.k.a no updates available also automatic transmission has lot of jerks when it switches gears... Example: half stop at stop sign and it accelerates without depressing the pedal and RPM going up but car not moving until half way down to intersection.

Transmission slipping on 2007 toyota sienna van. When traveling at 6-8 MPH the transmission will slip when the accelerator is depressed. The van will hesitate then suddenly lurch forward. The dealer says that this is normal and will not do anything to repair it.

This memo was sent via email on the toyota website over a week ago and have not received a response from them. I believe the issue is very serious and potentially life threatening. It is regards to a 2007 toyota sienna that I own. *tr at least five times in the last 3 months I have experienced a very serious episode with my sienna. While my foot is depressing the brake pedal and after coming to a full stop, the engine would begin to accelerate very rapidly. I need to push down very hard on the brake pedal in order not to lurch forward. I have been fortunate that I have not hit anything. What should I do. Because the problem only seems to occur randomly once in a while, a mechanic would not see anything wrong. Thank you jerry greenwald
