Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

To whom it may concern, I purchased a set of aftermarket replacement headlights for my 2004 Toyota Sienna that were advertised as dot/sae approved. www.am-autoparts.com/2004/Toyota/Sienna/headlight-assemblies/am-19245220/350742.html based on how far from the original equipment headlights these aftermarket lights performed (plus the fact they leaked) I went ahead and returned them. From my research it shows that the majority of aftermarket lights do not meet title 49, part 571-Federal Motor Vehicle Safety Standards, standard number 108 (FMVSS 108) and I am wondering why the dot and NHTSA is allowing them to be sold. Please take a look at this study by a lobbying group for these companies, whose own test results show they don't meet the oem standards that are required to meet FMVSS 108. www.capacertified.org/wp-content/uploads/2015/01/capalighting3.pdf respectfully, jonathan stein

Right passenger headlight has some sort of water leaking into the headlight. A substantial amount of moisture accumulates and can cause electrical issues.

This is a recurring incident. On cold days, the sliding doors will freeze shut. This is a common problem from my understanding, and some folks on web forums have recommended filing a complaint to hopefully get Toyota to issue a recall and resolve the issue. The freezing door problem is exacerbated by the electrical door lock mechanism and open/close sensor on the slider. In many cases, the failed attempt to open the frozen door is enough to trigger the door "open" sensor and cause the interior lights to come on.

The right headlight is out. Water, not just condensation, is visible inside the assembly. Advice being given is that I should replace the entire assembly (>$900) or the replacement bulb (~$140) will likely just blow again because of the leak that is allowing water in the assembly.

Condensation had been building for a few months in the right passenger side hid headlight, but headlight was still operational. The low beam headlight failed in February and the dealer quoted us a price of $900. For the parts alone. While doing research online for less expensive repair options, I noted many complaints about this specific problem with this model year. This is not the only expensive design flaw we have encountered with this vehicle (run-flat tires and no spare). I believe Toyota needs to stand by its customers and offer them a reasonably priced solution for these safety issues.

The contact owns a 2004 Toyota Sienna. The contact stated that moisture accumulated in the front passenger's side headlight, reducing the contact's visibility of the roadway. The vehicle was taken to a dealer for diagnosis and the contact was informed that the headlight assembly would need to be replaced. The manufacturer was made aware of the failure. The VIN was unavailable. The failure and current mileage was 100,000.

Right headlamp keeps filling with water causing severe fogging and putting my bulb out. This problem got progressively worse over a period of years and ruined the lens. I couldn't properly see on right side while driving. Kept going back to dealer about it but all they would tell me was turn my headlamps on longer or for long period of time until it dried out, then laughed. They finally wore me out after a couple of years of complaining. I had also complained about my tires making a loud thumping noise after about 16,000 miles and they had told me to turn my radio up louder, then laughed again. Also had a recall done there, and discovered my wheel well covering torn. They said they didn't do it but, it was the same side as the recall repair was on. They refused to repair it unless I pay for it. They=dealer= Liberty Toyota, burlington, NJ.

Drivers side low beam headlight stop working. Replaced hid bulb but still will not work. Swapped with passenger's side to confirm the bulb is ok (it is). There is a lot of condensation in the headlight assembly (due to the weather starting to cool down in northeast). After seeing all the complaints on this very issue I am now trying to figure out a next step. The dealership will quote me the $1K plus to fix the headlight assembly (complaints on this issue are rampant on various Sienna forums on the internet) since that is the root cause of the problem. My wife is upset since this a major safety issue in the winter. I will be calling Toyota to understand why they will not acknowledge a known defect in the headlamp assembly allowing condensation in and the bulbs to malfunction.

Purchased this vehicle certified used in 2007 with approx. 6 months left on the 3 year warranty... this vehicle has fog lights, daytime running lights, and xenon headlights/high beams. Of these eight settings (left and right) only one does not work -- the right side regular beam headlight. The R/S high beam works fine. R/S headlight was intermittent from date of purchase. Appeared to be a simple electrical connection failure as headlight would come back on after a slight strike of the headlight unit. Also noticed unit would accumulate condensation after rains. Eventually light started going out more often and staying on for less time. By December the light would not come on at all. Scheduled a service visit with oil change but could not stay long enough to fully solve the problem. Came back in January for full evaluation. After an entire day of troubleshooting, the technician brought me back to show me that the headlight bulb worked in the left side unit fine. Also, the right side unit worked on the left side while the left side unit showed malfunction on the right side -- indicating both the units worked fine, but problem was another section (the ballast?). Toyota suggested replacing the whole unit (despite the fact that they proved to me that it worked) at a price of $1000 plus labor (since it was no longer under warranty). I declined the obviously ridiculous suggestion and took it home to try my own troubleshooting. I discovered I could get the light to come on by pulling tight the wire dedicated to the R/S xenon bulb straight back from the unit. This caused the light to come on and stay on often, though not always, similar to the time it was purchased. However, after the very first heavy rain, the headlight unit had extensive condensation inside the plexiglass and the light never worked again.

The electric door (passenger side) intermittently worked for years, sometimes it worked, sometimes it did not. Finally it quit working. The rear fan goes on and off at will. There is an electrical short. My rear tail light on driver's side is always out, even after replacing it multiple times. The trunk door lost all its hydraulic lift and actually hit me in the head. It has no hydraulics left now and is very hard to lift. The lighted buttons by the front windshield where you operate the garage door, electric door - burnt out at probably 37,000 miles and were ridiculous to replace. The door locks are all screwed up. Hard to unlock the driver's door manually with a key, have to unlock from passenger side. The door clicker does not work. Batteries have been replaced multiple times and the clicker quit working shortly after, again an electrical short of some sort"?" so no clicker, no electric door, no trunk lift, no dome lighting, no tail light, not to mention all the recalls that van had (extra tire, seatbelts, door issues). I had to replace my radiator?? cause it was leaking. Van currently has 126,000 miles on it. It is by far the worst quality vehicle I have ever owned. I have owned an 80S Toyota corolla which was fine, Saturn, Acura integra, Ford Explorer, also Mazda, 2001 Chrysler 300M (horrible also), there is no doubt that after reading all the posts on the edmunds site about this 2004 Sienna van, it should be recalled for electric door problems and all door problems.

I noticed that the passenger side headlight has condensation on the inside. I have noticed the light appears to be giving off less light when driving. When checking for a solution on internet I see many people have the same problem. This should be investigated and a recall should be done as this can cause an serious and potential accident if the light fails from the moisture.

2004 Toyota Sienna moisture in passenger side headlight assembly diminishes the brightness of the light and reduces visibility. To replace the assembly the dealer quoted over $400. This is apparently a problem many Toyota Sienna owners have. Toyota should issue a recall for this problem which is a safety issue. Driving on dark, small winding roads with one headlight not giving out enough light is dangerous. Shame on Toyota for ignoring this problem!

Problem with condensation in the headlights of a 2004 Toyota Sienna. Problem first started with condensation only in passenger side. Eventually the light stopped working all together. Several dealers attempted to resolve the problem by replacing bulb, attempting to replace the entire headlight assembly, but have not been able to fix the problem. Now, condensation has appeared in the driver side headlight and it too has stopped working. Research online indicates that this is a common problem and dealer wanting to replace entire assembly at a cost of over $1000 per light. Judging by the number of complaints, this is truly a defect and should be considered a safety issue. I also see complaints of something similar with Toyota prius.

The passenger side headlight assembly accumulates moisture inside due to the design of the headlight. The headlight will suddenly go out while driving. Toyota claims it is not covered under warranty and has an estimated repair charge of $1200 to replace headlight assembly. Many Toyota owners have complained about the failure of the hid bulbs that are being used and the defective nature of the headlight assembly. Once repaired, it reportedly keeps occurring. Mine went out while driving in the dark in the mountains- could not continue on trip due to the hazard of not being able to see on the windy dark roads.

Under normal operating conditions, 2004 Toyota Sienna xle limited with hid headlights, had premature headlight failure. Mechanic diagnosed the problem as a faulty transformer and replaced it under warranty. Within a few weeks, the other side transformer failed. Mechanic replaced that transformer. Within a few days, that transformer failed too. Issue currently under investigation with Toyota.

Headlamp on 2004 Toyota Sienna failed intermittently, and then seemed to work. Eventually it stopped working altogether. Diagnosis was moisture in the assembly, causing it to short out. Price to repair? $1700, of course not covered by Toyota. Apparently this is a design flaw, based on the number of other complaints, and it's definitely a safety concern.

2004 Toyota Sienna, passenger side headlight fills with condensation making the headlight dim and reducing visibility for night-time driving, also causing lightbulbs to fail intermittently. Took van to dealer today. They quoted $445 to fix it. Came home and found other people complained of the same problem on their 2004 Sienna, also on the passenger side only. This suggests a defect since it is always on the same side of the vehicle. Other owners also reported impaired night driving visibility because the headlight is fogged over with condensation.
