1 Headlights problem

Failure Date: 02/21/2018

The headlight bulb compartment allows water to leak into it on the passenger side causing the bulb to blow. This has happened twice, the repair cost was $500. We drove the car for one week and the bulb blew again because water leaked into the compartment. This is a design flaw and is hazardous when you are driving at night or god forbid if it's raining and dark. We also were pulled over and given a warning from a state trooper about the bulb being out. This is a dangerous and costly situation. We are still waiting to get the bulb repaired a second time. In the meantime we are without a van for our family. Please demand that Toyota recalls this hazardous defective part. The bulb went out while we were driving at night. This is a problem and a hazard!.

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. . Read more...

3 Headlights problem

Failure Date: 03/02/2014

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

4 Headlights problem

Failure Date: 09/02/2013

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.

5 Headlights problem

Failure Date: 02/04/2013

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.

6 Headlights problem

Failure Date: 10/08/2012

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.

7 Headlights problem

Failure Date: 05/16/2012

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.

8 Headlights problem

Failure Date: 04/18/2012

The right side headlight assembly is accumulating moisture and condensation inside which causes the headlight to fail.

9 Headlights problem

Failure Date: 10/22/2011

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.

10 Headlights problem

Failure Date: 07/01/2011

The contact owns a 2004 Toyota Sienna. The contact stated that water was leaking into the passenger side headlight. The manufacturer was notified of the failure, but denied any assistance with repairs to the vehicle. The dealer was not contacted. The vehicle was not repaired. The failure mileage was 45,000 and the current mileage was 51,000.

11 Headlights problem

Failure Date: 03/31/2011

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!.

12 Headlights problem

Failure Date: 01/02/2010

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.

13 Headlights problem

Failure Date: 10/01/2009

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.

14 Headlights problem

Failure Date: 09/16/2009

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.

15 Headlights problem

Failure Date: 12/29/2008

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.

16 Headlights problem

Ecu headlight.

17 Headlights problem

Failure Date: 04/11/2008

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. 00 to fix one headlight. $ 800. 00 of this was a ?igniter? part from Toyota and $ 100. 00 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.

18 Headlights problem

Failure Date: 02/07/2008

Initially the dr side low beam headlight would not light. Dealer replaced bulb and ecu module. Warranty replacement. Cause was reported the ecu failed. Months later the dr side low beam headlight failed again but after the one year repair work warranty. This time it was reported to be the bulb and was replaced, dlr. Would not warrant the work, even the extended warranty supposedly did not cover. Cost to cust. Was $395. Currently the passenger side low beam headlight has quit working, several months ago and cust. Bought direct replacement bulb and installed it. That did not remedy the problem. It appears that the ecu for the passenger side low beam headlight may be faulty. It has been reported that costs for the ecu and dlr labor to replace would cost about $800. This seems to fall in the safety category and should be a recall and warranty work. Different dlr states that they can diagnose for $125 and determine the problem. Oh what to do! please help. All for seemingly a burned out headlamp. The service attitude and associated costs by the mfr. And dealers are piracy to say the least. I wouldn't mind paying my way but this seems to be a problem that is more widespread than just a few. Even in some other models. Unconscionable policy!.

19 Headlights problem

Failure Date: 12/01/2007

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.

20 Headlights problem

Failure Date: 11/05/2007

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.

21 Headlights problem

Failure Date: 10/11/2007

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.

22 Headlights problem

Failure Date: 07/05/2007

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.

23 Headlights problem

Failure Date: 05/15/2006

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. 00 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. 00 (dealer wanted $350. 00 for the bulb!) Toyota care denied my request for no-charge replacement of the passenger side headlight lens assembly.

24 Headlights problem

Failure Date: 01/10/2006

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.

25 Headlights problem

Failure Date: 07/15/2004

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.

26 Headlights problem

Failure Date: 03/17/2004

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.
