Sienna 6-cyl

  • 146,455 miles


I attempted to merge onto the expressway and after pushing the gas pedal the van suddenly accelerated beyond my control. I eased off the pedal and the van continued to serge ahead with no way for me to stop or slow it down as the brakes would not work. I saw the RPM reach level 6 and speed increase to 70 in seconds but as it was the expressway, I was able to keep my distance from cars in front of me. I switched the lever to the neutral position and the van slowed down and then I went back to drive and it roared back up to 70 mph with the RPM again at 6 and I tried turning the cruise control on and then braking to see if it would shut down the gas but no luck. I went back and forth from D to N for about 2 minutes and then on one of the movements from N to D it shut down back to normal. I dropped the van off at my Toyota dealer the next day and am waiting to see what "headquarters " decides.

On my 2004 Toyota Sienna minivan the rear hatchback gas struts have failed. This is a dangerous situation that could easily get a small child killed. I almost had this happen when my 5 year old was helping to get groceries out while I was holding the gate open it slipped and came crashing down. Luckily he had just moved and it missed him. These gas struts are a recall item on the power operated lift gates, why aren't they on the manual ones. And the cost of replacements is terrible, $180/ea.

After opening and closing the fuel cap door on the 2004 Sienna causes the driver side sliding door to intermittently jam and not open. This has happened several times in the past 2 years. To fix, one must squeeze hand into door crack and push down the lever that is stopping the door from sliding. Sometimes this jam causes the door to not close.

The fuel pipe from the tank to the engine on my 2004 Toyota Sienna le disconnected. I was driving with my kids and stopped at the light, our car being the first in the rightmost lane at a busy intersection. When the light turned green I pressed the accelerator but the car didn't move. I made several more attempts but it was in vain. The message on the screen panel appeared as a discharged battery, which at that moment puzzled me very much. I started looking around, making signs to the vehicles behind mine to try and get into the other lane as I can't start my car (there were few angry drivers). One stopped by me when the light turned red again and then said he smells gas. At the same time a woman and her older teenage daughter were running from across the street waiving and shouting 'get out of the car!'. she helped me and my kids get out and told us that while driving from the other side she saw when the gas gushed from under my car. Well the rest is known - 911, police, fire truck and my family scared and blessed to have escaped a horror. The car was towed to the dealer who told me that the pipe disconnected, they put it back and that they've never encountered this problem. When I asked about a warranty on this or a future sign to look for, the answer was it shouldn't happen, it can't. but it just did, right? I want to mention that the car has never been involved in any accidents and it's very well cared for. I had to pay for the repair over $100 which I'm guessing Toyota will never refund. I will forever be thankful to that woman and her daughter who quite possible saved out lives.

  • Automatic transmission

Radiator ruptured and the engine overheated; hose replaced in steering column recall; rust protective tape recall; dvd screen replaced and the entire dvd player replaced(screen still not easily visible in middle row); passenger seat belt replaced; middle passenger seat belt failing; gasoline smell inside of car with ac on recirculation; driver's window fell inside door in snow storm and was not considered a safety issue to get a loaner vehicle even though the vehicle could not be locked; tires completely bald and leaking under 30,000 miles, dvd player must be at a high db volume and when returned to radio/cd will almost deafen you; interior lights have to be manually over ridden or will drain battery; car hesitates 1-2 seconds when trying to quickly accelerate and then lurches forward alarmingly; cruise control is not functioning; waiting to have fuel mixture sensor replaced. I was not informed of first 2 recalls until I my engine overheated. I did get the rust recall and a sticker on my sliding door informing user of danger of having middle windows open while opening the middle door could catch a head or other extremity. Toyota dealer service manager says mine is the only 04 Sienna experiencing any problems except for the recalls on the radiator; the steering hose; the rust tape; and the middle seat belt. Not so according to all I have read here. Most of the problems have occurred between 22,000 and 34,000 miles; the dvd screen always failed to lock into a good position for the middle row viewers.
