Hatchback/liftgate Lock problems of the 2004 Toyota Sienna

The automatic rear hatch of my 2004 Sienna will not stay open. . The safety feature is not working and it continues to close even if you are standing underneath it. . It will not stay open. . Dangerous for me and the kids!.

My wife and I own a 2004 Toyota Sienna xle with a power rear door. This morning the rear door opened normally; however, as soon as the door opened completely it closed immediately hitting me in the back of the head. I attempted to open the door using the interior button as well as the remote; the door closed immediately regardless of which method I used. I also tried pushing up on the door as it closed which worked but took a great deal of effort. If my five year old was under the door he would not be able to hold the door back and may be seriously injured. I opened the door about five times before the door stayed open.

Yesterday, my wife opened the power rear door of our 2004 Sienna xle to get some items from the inside of the van. As the door got to the apex, she started to reach into the car, but the door slammed down violently hitting her in the back. We had never had a problem before so she tried it again, but stood back this time. The power door slowly lifted up and then suddenly slammed down. This is a heavy door so you would not want to be hit in the head or body when it slams down. I got the same results when I tried it. Apparently Toyota has a service bulletin out about this problem and there is an ongoing investigation. I sure hope this gets figured out before a child gets hurt! Toyota dealer acknowledged the problem and is working with to replace necessary parts for little to no cost.

Rear hatch closes on person without warning. Rear hatch does not stay open.

The powered liftgate of my 2004 Sienna doesn't stay up when open. It closes regardless of someone being under. I personally got hurt when the door closed one time and my son almost got pinned down as well. I am seeing on the internet a lot of people having the same problem and yet I am surprised that Toyota has not issued a recall for such a serious issue. I am taking my car to the dealer to get this fixed since I cannot open the liftgate anymore due to this issue. I believe this is a problem with the gas struts that are defective. After talking to my dealer, this one doesn't seem to think this is a serious issue and that they should take care of it at no charge. Fyi I already replaced these gas struts once (yes this will be the 3rd set in 4 years!).

2004 Toyota Sienna xle limited awd. Power liftgate does not fully open up when I try to open the liftgate with the switch at the driver's console. Manually open the liftgate does the same. This problem started happening sometime in October, 2007 and now the liftgate opening is getting lower than first experienced. I hit my head on the liftgate few times.

The rear hatch opens fine but starts closing automatically (it is electric) a few seconds after it opens all the way when cold even when no buttons nor the door are touched.

I have a2004 Sienna xle. Last Sunday October 28,2007 the lift back door when opened (powered ) and reach it's highest point when all of a sudden it jerked downwards forcefully nd hit my husband(-trying to put grocery). It should have stayed up. The mileage is just 17,000+ even though it was bought July 2004. It has since never worked. It does open but jerks back down again when it reached the top.

I have a 2004 Toyota Sienna and the power liftgate is closing unexpectedly. My wife's arm was squeezed the other day because of this liftgate closing by itself while she was getting groceries out of the car.

The contact owns a 2004 Toyota Sienna. The contact stated that the rear lift gate fails to remain open at the appropriate times. When the lift gate is opened automatically, it rapidly falls and closes. When opened manually, the lift gate closes automatically and without hesitation. He emailed the manufacturer, but has not yet received a response. The contact stated that there is a NHTSA defect investigation (pe06029) in regards to this failure. The current and failure mileages were 75,000. Updated 08/29/07.

Rear hatch support cylinder failed. I purchased a new cylinder and replaced it myself. At a cost of $150. 00 for one. I started to notice the problem when my automatic rear hatch would only raise the hatch half way and then re-close the hatch. 2004 Sienna xle limited. 45k updated 10/03/07.

I have a 2004 Toyota Sienna, which overall I love. In the past 3 months, the trunk hatch has started to not hold when open & resist opening at times. It used to hold for longer, making me delay the repair. It has progressively gotten worse, so that now it closes within moments with a lot of force. I have no choice but to repair it now, at a cost of $400, or risk serious injury to myself & 3 young children. My husband & I have already been bonked on the head & back repeatedly. Toyota is aware of the defect, & the obvious risk to car owners (a majority of whom have young children I would guess as it is a minivan), but has not issued a recall. Instead they are profiting over the defect. I don't fault the service dealer that we deal with, as they have always been helpful & honest. I am upset that the Toyota corp. Won't issue a recall.

Rear liftgate on 2004 Toyota Sienna failed. It was in up position and suddenly came down and I was unable to get it up while I was under it loading groceries. The weight of the door hit my shoulder first and knocked me into the back of the van. I was then able to push it back up after I dropped the grocery bags. The door came down very fast and forceful,ly. I was sore but very thankful that my 4 year old wasn't under the lift gate with me.

The lift gate has fallen unexpectedly on several occassions. My wife, my mother-in-law and my child have all been "hit" on separate occassions by the gate during this malfunction. The dealer has advised that the struts need to be replaced.

Relating to current investigation of 2004 Toyota Sienna rear liftgate strut failure NHTSA recall campaign number: ea06020). My wife has a 2004 Sienna xle with the power liftgate and the struts just failed, causing the liftgate to close and requiring help from a friend standing nearby to help her hold it up to remove our children's stroller. I looked at it this evening and noticed grease around one of the cylinders where the seal had obviously failed. While I was looking at the struts I took my hand off of the hatch for a second mistakenly thinking that the power assembly would hold it up and it immediately came down and hit me in the head, causing luckily only a headache. After researching the problem and finding the ongoing investigation I wanted to add my name to the list of complaintants and suggestions that Toyota be required to fix the defect and replace the struts. Note: I entered 2 in the number of failures box since both struts failed and I entered 1 in the persons injured because it did hit me in the head hard enough to give me a headache ,and I am a 200 lbs man. My fear was that if it would have closed on one of my children that it could have caused serious injury. I will be shopping tomorrow for replacement struts from an aftermarket dealer because in my research I have found people on their 2nd, 3rd, and even 4th sets of struts replaced under warranty. Unfortunately, my Sienna was conveniently at 39,000 miles, 3,000 miles out of warranty.

Liftgate hazard -- I own a 2004 Toyota Sienna, with manual liftgate. The liftgate struts/supports have failed. I was hit on the head and shoulder, but was not seriously hurt. Jb.

The rear door on the 2004 Toyota Sienna van camer down by itself. The motorized hatch went up and then almost immediately came down. I was getting items out of the back when it hit the top of my head. It kept closing until I hit the remote button , but as soon as it reached the top,it started to close again. I contacted Toyota, and they told me the warranty expired, and it would cost $470. 92 to fix it. This was a safety issue and could cause major injury, especially to a small child. I think they should be responsible.

The power liftgate on my 2004 Sienna closes on its own after I open it. The liftgate has struck me on the head and shoulders on several occasions. About a year ago Toyota replaced the gas pistons but the situation has reoccured, especially in cold weather. Today, it closed on its own three times.

Hatch on my 2004 Toyota Sienna van comes down by itself. It is the limited edition version with motorized hatch raising and lowering. It goes up and then comes down by itself. I was standing underneath and it struck the top of my head and gave me a stiff/sore neck. It does this intermittenly, not all of the time. I contacted Toyota and told me my warranty is out of date and would not repair it. This is a safety issue and could cause major injury especially to a small child and I think they should be responsible. This is not like a fan belt or alternator where the failure cannot actually injury someone. I understand this has been corrected on the newer Siennas that still have the same body style, so they obviously know it was a problem.

Struts on rear liftgate failed, injuring my back.

- the contact stated that when he opened the rear liftgate of the 2004 Toyota Sienna using the remote control access the gate will rise to the top and immediately come down without warning.

The gate did not lower without warning when it was opened manually. The contact spoke with the dealership, and was informed they would not replace or fix until they received something from Toyota. The failure mileage was 28200, and the current mileage was 28400. The consumer stated the rear lift gate somtimes lowers without warning during the opening cycle. Updated 03/19/07.

In December, 2006, my tailgate closed on its own, injuring my wife. Toyota replaced the rear stays (struts) under warranty, including the addition of some brackets. At first everything was fine. But when the weather turned colder (below 20f), the rear hatch would not open on its own unless opening under power. And then a couple of days ago (still very cold), the hatch closed on its own under power again. This time, my daughter and I were both in its path, but fortunately, so was a shopping cart. There were fortunately no injuries this time. I am frustrated that just 45 days after the problem was "repaired" it is already happening again.

The contact owns a 2004 Toyota Sienna. The contact stated that the rear lift gate closes unexpectedly and on its own. She stated that it closes with such force, that it makes it very difficult to re-open. The dealer and the manufacturer have not been notified. The failure has caused the contact's husband to sustain a strained back. The VIN and engine size were unknown. The current mileage was 20,000 and failure mileage was 15,000.

The rear lift gate lost its full up position and rapidly came down. The power close function kicked in was near impossible to push back to keep it from crushing me. The pressure sensor did not seem to function. The rear lift gate is currently useless but poses a major safety concern with kids in our family. The dealer has not shown the expected sense of urgency in getting this problem fixed. This is our first new Toyota and I am terribly disappointed with this situation, this will certainly affect my decision to buy another Toyota brand if the problem is not addressed to my satisfaction.

1. Nothing 2. Hatch would not stay up/ fell down on person trying to put stuff in hatch 3. Dealership is ordering part.

Failure of the rear hatch support mechanism ,making the hatch extremely difficult to raise, and when released causes it to crash down with great force on top of a person that may be under it.

Liftgate doesn't open fully.

2004 Toyota Sienna liftgate closing automatically and striking the owner's head; problem occurred intermittently. At times the open door was activated, the door began to close, didn't close completely, would re-open and close again until forced physically into an upright position with some force.

(1) we have a 2004-2005 Toyota Sienna xle with the back hatch that opens and closes automatically. We used our back hatch regularly and it hasn't been misused. We have opened it using the keyless remote, the ceiling mounted keypad, and manually. However, our hatch has not been working properly since February 2006. (2) when we use the button on our keyless remote or on the ceiling mounted keypad, the hatch opens but as soon as it reaches the maximum height, it automatically closes. When it encounters an obstacle, it does not open again as it should, but rather continues to close unless extreme force is applied. I have been trapped by the door on several occasions and my daughter (age 3) was almost pinned by the door as well. When we try to open the door manually, the automatic hatch does not work at all so we have to prop the door open with a large wooden stake or try to hold it open with one hand while attempting to place items in the trunk with the other hand. At times the stake has fallen causing the door to slam shut quickly. Also, at a certain height, the door will just begin to close automatically even though I am attempting to hold it open. I find this situation to be extremely dangerous and have avoided using our back hatch whenever possible. In addition, the automatic side doors are also supposed to reopen if they encounter an obstacle, but I have found that this is not the case. They require a great amount of force to reopen. The doors have almost shut on our children several times. Had I not been standing right there to force the door open, they would have been pinned. I am very concerned about the danger of this situation as well. (3) we attempted to fix the back hatch earlier this spring, but the service department did not have the part and said it would take 30 days b/f it would come in. We have not taken it back, particularly b/c the cost of replacing the part was $300+ which is too expensive for us at this point.

Automatic hatchback on the Mini van came down and didn't stop with the consumer in the way. The vehicle is being taken to the dealership tonight. The hatchback hit the consumer in the head, it didn't stop the hatchback pushed the consumer into the van and her mother had to grab it to stop it.
