36 Electrical System problem

Failure Date: 01/10/2011

Toyota Sienna xle 2005: automatic sliding door problem purchased this vehicle used one year ago (2010). There were no previous problems with the door, that I know of. Both sliding doors started failing during winter time. One motor was replaced, the other one not due to cost. The driver side sliding door worked "on and off", but is not working now. It opens and shuts with a manual pull of the handle.

37 Electrical System problem

Failure Date: 01/01/2011

While engine is running, key may be removed. Technician could not find any problem which would allow the key to be removed while the engine is still running. Repair could not be made since no problem could be found to correct the issue.

38 Electrical System problem

Failure Date: 11/24/2010

Middle row driver side seatbelt failure and passenger side sliding door power failure.

39 Electrical System problem

Failure Date: 09/17/2010

The cable related to the automatic sliding passenger door on my 2005 Toyota Sienna snapped. I took it to the dealer and he said it rusted through. The wire for the sliding door mechanism is on the outside of the vehicle. I has thin layer of black protective coating. It will cost $1800 to repair as the cable and motor are one unit. It is beyond comprehension why an oem would design an automobile with the cable system exposed to the elements. The extreme weather in minnesota we experience is quite taxing to an automobile, regardless of electrical design. But to have the electrical components exposed to salt and other corrosive materials is just really bad product design and should be corrected.

40 Electrical System problem

Failure Date: 07/12/2010

Automatic rear doors will not lock or unlock or open or shut with remote. Are extremely difficult to open manually. I was told they could be repaired at a cost of over $1200 per door. I also had a problem with the rear automatic hatch which was repaired under warranty. I see a pattern here.

41 Electrical System problem

Failure Date: 03/01/2010

Automatic sliding door will not work properly. It will not shut unless done manually. Occurred soon after passing 50k miles. Dealership "could not diagnose problem" and wanted ~$1200 to replace motor in door. Appears this is a common problem that Toyota will not address.

42 Electrical System problem

Failure Date: 02/12/2010

The electronic throttle control system on my van is malfunctioning and it puts the vehicle in "fail safe" mode. The local Toyota dealer as well as Toyota customer service do not want to investigate this recurring problem for the dtc p0121. The dealers do not analyze the freeze frame data or investigate the problem beyond reading the code from obd ii scanner. I had asked them for the electrical values for the throttle valve motor and the accelerator pedal but they have refused that information and want me to replace the throttle body by spending $1200. 00. The first time this problem started when the vehicle had 50,000 miles and I replaced the throttle body from same year and model vehicle with 20,000 miles. Now after 10,000 miles same problem has started again and the dealer as well as Toyota want me to replace the throttle body. I feel that the throttle body or the gas pedal in conjunction with other electrical components are causing the dtc code and merely replacing the throttle body second time will not fix the problem unless the newer throttle bodies are without the problem original throttle bodies had. In that case I should not have to pay for the replacement part. It is important that the problem is investigated and identified before any parts are replaced. I also offered Toyota the original throttle body from the vehicle for testing / checking for the problem but they refused my offer. This sudden loss of drivebility due to the activation of "fail safe" mode is dangerous and could result in accident and / or fatality. Any help in this matter will be appreciated.

43 Electrical System problem

Failure Date: 04/21/2009

2005 Toyota Sienna van - sliding door failure (driver's side). Dealer says it is a broken motor & cables. Vehicle has only 41,000 miles on it (warranty expired at 36,000). Dealer wants to charge me $2,000. Searching the internet I found hundreds of posts from people with similar problems. This is a problem that Toyota knows about and should recall as they did with both the rear hatch struts and both front door hinges. I just had my vehicle in the shop last month for both of these fixes.

44 Electrical System problem

Failure Date: 03/01/2009

2005 Toyota Sienna has a passenger side power sliding door that has gone through the stages of sticking, rubbing against the body and rubber stripping around windows, and now, working at all through the power button option (or the remote) -- only way to get it open is via the door handle. This seems to be a recurrent problem in a number of Toyota Sienna but the manufacturer has not issued a recall so far. I deem this a safety issue because the door fails to close many many times and the driver has to get out of the vehicle to close the door in frustration and that can create unsafe situations.

45 Electrical System problem

Failure Date: 01/10/2009

I have a 2005 Sienna that I purchased about 3 years ago. For about two years it has had the problem of not closing. At first it would only close every now and then, and now it won't open or close at all. When the weather is cold, neither of the sliding door will open unless you climb in the front and kick it open. I've taken it into the sandy, utah dealership about 5 different times to have them check it out and they said nothing was wrong with it. I'm about to take it in again because now it won't work at all, so I did a little research to find out if there was a recall or if others had the same problem. To my surprise there are numerous people having the same problem with their 2004-2006 Sienna's. Why then is there no recall? why are people getting the run around from dealerships, poor service and being charged a mint to repair the door? why is this product and service such poor quality?.

46 Electrical System problem

Our 2005 Toyota Sienna has had multiple problems with the power sliding doors. Originally, the driver's side door stopped closing automatically. When button was pushed to close the door by all methods, on remote control, on driver's head panel or on panel next to sliding door, the door would begin to close then slide back open without warning or without us doing anything to open it back up. Our local dealer fixed this original problem as it was under warranty, but now the passenger side power sliding door has the same problem but we are out of warranty and the cost is too exuberant for us to have it fixed. This appears to be a problem for many Toyota Sienna owners and can possibly be a danger.

The contact owns a 2005 Toyota Sienna. The contact stated that the passenger side sliding door would not open in the vehicle. There is a button in the vehicle that automatically opens the sliding doors, but it is no longer working. The warranty already expired when the failure occurred. The vehicle was taken to the dealer and they stated that the motor and clutch assemblies failed. The vehicle was repaired, but the contact was unable to explain exactly what was done to the vehicle. The vehicle is no longer experiencing the failure, but she believes that this should have been covered as a manufacturer defect. The current and failure mileages were 35,523.

Sliding door is not open and close when using electrical button. We got the extend warranty but when we bring to Toyota dealer they told us have to pay $295. 00 to check it . If a defect is not under warranty. I fill it is not fair. Door is not open because the latch was not release by pushing button. Is it safe when children are in side? if we remove the latch everything is working fine. Please help american consumer to make Toyota responsible for any lack of assembly. They have to pay for the time of inconvenient also. Please investigate this issue. Thank you.

52 Electrical System problem

Failure Date: 02/20/2006

I have a complaint about Sienna's vsc system. It overreacts suddenly and at too much a rate, in an anticipated little skidding that had been easily corrected manually in my previous experience with other cars. I have a 2005 Sienna le awd. It comes with vsc, abs, trac. I was cornering a 30 mph left turn with the van going 35 mph on highway 431 in nevada. It was down hill, so I was using low gear (3) to apply engine braking. It was not snowing. The road was dry without snow. On the side of the road, there were some gravels/salts. The van veered to the right a bit as I was making a wide turn. It went off the lane about 1 or 2 feet onto the shoulder, but still on pavement. On the shoulder, the front wheels skidded by a very little amount, which is anticipated and normal in my driving experience and had always been handled with ease. However, the vsc kicked in suddenly, causing the van to turn to the left tightly and at a very fast rate, into the opposite lane on the undivided 2-lane highway. It all happened in a blink of eyes. Fortunately, there was no traffic in the opposite lane, and I was alert enough to quickly steer the van back to my lane, avoiding hitting the mountain on the left. The vsc light did come on in few other occasions, but the van was never out of my control in those cases. From my past driving experience of 20 years (many of which were with snow), I really feel this is an overcorrection by the vsc by a huge amount. I am starting to feel very uncomfortable that such vsc reaction can't be reduced (e. G. , to a slower and lesser rate) or completely turned off. It's winter time again and I am going to ski with my family. It reminds me that I have not filed this complaint yet and that I will have to be driving nervously, who knows when vsc is to kick in again, by how much amount, or at what rate.
