The contact owns a 2004 Toyota Sienna. The contact stated that the front passenger side headlight collects condensation. The failure has been occurring for one year. He discovered that many other consumers were experiencing the same issue and decided to file a report. The dealer was notified and disregarded the issue. The failure mileage was 75,000 and current mileage was 110,000.

I own a 2004 Toyota Sienna with 76,000 miles on it. I was one of the first owners when the new model was introduced. It has been well maintained through molle Toyota, kc mo that I have been pleased with prior to this incident. I had some problems with it initially and Toyota motor sales always took care of it and provided excellent service and follow up. However, the reputation that they have built over the course of 4 years has come unraveled. One of my headlights went out recently and I took it in to the dealer to get fixed, assuming it needed a new bulb. I was presented with a projected price of $ $900 to fix one headlight. $ $800 of this was a "igniter" part from Toyota and $ $100 of this was labor from the dealer. I filed a complaint with Toyota motor and it was bounced back to the dealer who delivered the message that there was no other option but to pay this, due to the high mileage. Clearly, this is a safety issue as I can not afford to fix this and can not drive the car without headlights. A realistic repair expectation would be to replace a bulb. This is an outrageous expense that Toyota should incur. Thank you, patrice lofquist

I have a 2004 Toyota Sienna that has a large amount of condensation inside of the passenger side headlight assembly. I first noticed it in December when the condensation froze and considerably blocked the headlight beam. When researching on the internet to find out how to take the lens off to dry the condensation I discovered that the beam assembly does not come apart and that many other owner's of the same model are having the same problem. In addition, this problem always seems to be reported on the passenger side. Eventually the condensation will cause the light to fail. Toyota redesigned the Sienna in 2004 and the new, bigger headlights were a major change. The condensation slightly affects the headlights in the warmer months but is a significant problem when the temperatures are below freezing. This seems to be a design flaw affecting vehicle safety that Toyota should be required to fix.

Headlight, hid, passenger side. Lens filled with water (condensation?) and would not dry. Water would actually stream down the inside of the lens. Soon my hid bulb stopped working. Dealer wanted $350 for a new bulb. I told the dealer I had switched the driver and passenger bulbs and they both worked on the driver side and neither worked on passenger side. Dealer then quoted $1,000 for new headlight assembly. Dealer told me the water in the passenger side lens was normal but had no explanation for why the driver side was dry. I did an internet search and also checked siennaclub.org and found very many complaints about wet passenger side lenses and passenger side failed hid bulbs. By the way, I bought a new sylvania hid bulb, new in the box on E-bay for $45 (dealer wanted $350 for the bulb!) Toyota care denied my request for no-charge replacement of the passenger side headlight lens assembly.

In regards to a 2003 Toyota Sienna xle model with high intensity discharge headlamps: In June of 2007 with vehicle out of warranty by mileage, but not time, driver's side headlight stopped working. Initial recommendation by dealer (boch Toyota of norwood, MA) was to replace hid computer at a cost of 1,100 dollars. Following replacement of hid computer, light operated for approximately three months before beginning to operate intermittently. Was then told by dealer that there was a "short in the bulb" and dealer recommendation was to replace bulb assembly at cost of 400 dollars. Within two weeks of this repair, I was stopped by a police officer and told the headlight was not working. Again, headlight is working intermittently. Today dealer recommended replacement of entire headlight housing at a cost of 1,100 dollars. A brief review of postings to Toyota owners' forums reveals many mentions of hid headlight failure in new vehicles, particularly the 2006-2007 prius models. All drivers report intermittent operation and dealers who are unable to solve the problem. The common solution, "toggle your headlight switch off and on a few times to get them working again" is a clear safety concern, and not an appropriate repair.

Condensation builds up in the passenger headlight. The condensation reduces the effectiveness of the headlight, creating a dark spot on the right side. This is a common problem with 2004 models. There are hundreds of threads on Toyota/Sienna forums online where owners are having the exact same problem. Toyota is ignoring this safety problem.

Headlight design allows moisture and condensation inside headlight assembly causing variable and decreased lighting effectiveness. Entire inside of headlight assembly can be coated with moisture. Moisture clears and recurred depending on weather conditions. Toyota dealer declined to fix.

The new model year 04 Toyota Sienna vans and highlander SUV have poorly designed and or misadjusted daytime running lights, causing blinding glare to oncoming drivers, drivers in front of these vehicles and pedestrians walking at night. These excessively glaring lights distract and cause eye pain to other drivers and temporary blindness. This is a serious safety problem that needs to be addressed especially for pedestrians walking against traffic at night.

In my area there are a lot 2004 Toyota Sienna's. whenever I pass this vehicle I'm almost getting blind from the powerful headlamps. It seems that the headlamps are not properly aimed. I would recommend that Toyota should test that again, and recall all the Siennas for proper alignment.
