In daylight, when headlights are off or automatic, the speedometer does not illuminate. With headlights on, illumination is very faint at its maximum setting. The display is so dark that it cannot be reliably read. With sunglasses, it is impossible to read the speedometer. Note, this is an analog speedometer, and this model does not have an additional digital speed display. An internet search indicates that this problem is universal for this model/year (not a defect in my vehicle). It creates a hazard because one cannot easily determine speed. (at night there is no problem, since the dashboard lighting is sufficient in those conditions. ).

The passenger side headlight turns off intermittently. It will turn on again if you turn the headlights off and back on, but then will go out again. I have read online about many other Toyota owners, specifically those with priuses, but also some Siennas, having this problem. Dealers don't know how to resolve it - mine wants to replace the bulb for close to $500, but can't guarantee this will resolve the problem and the bulb is apparently working, just not all the time. This is a safety issue to have a non-working headlight.

When the headlights are off, the dashboard instruments (speedometer) are very difficult to seen when overcast outside (no back-lighting). This is our 3rd Sienna and was not an issue with past models (2011 & 2013). This is a safety issue in the it require eyes off the road longer than necessary in order to ready the instruments.

The right side (passenger) headlight went out. Replacement of the light bulb (which was a whopping 190. 00) did not solve the problem. Was told that it is a special type of hid light which has a headlamp control module aka ballast aka computer that could be bad. Dealer quoted $600 to fix a headlight. My other repair shop quoted $450. Really Toyota? $450-600 to fix a headlight???? ridiculous. No one should have to pay this much to fix a headlight. Who engineered this? beyond frustrated.
The contact owns a 2010 Toyota Sienna. The contact stated that the headlight assembly covers were foggy and created dull illumination at a distance. The dealer stated that they had a process to spray the headlight covers and make them ultraviolet, but there was no explanation as to what caused the issue. The manufacturer was made aware of the failure and stated that it was normal wear and tear. The failure mileage was approximately 57,000.

My 2014 Toyota Sienna does not have the dashboard instrument lights on when driving. The instrument cluster is hooded to shield it from sunlight. Auxiliary lighting is required to clearly see and read the dials and instruments. Not being able to quickly and easily reading these dials can be a safety issue. The only way to turn on the dashboard lights is to (1) turn on the parking lights or (2) turn on the headlights. This is contrary to other vehicles we have owned, including Toyotas. Toyota has told me that this is standard. I disagree. I feel that Toyota should turn on the instrument lights when I start the engine. .

Right passenger headlight has some sort of water leaking into the headlight. A substantial amount of moisture accumulates and can cause electrical issues.
There is no illumination of the main dashboard display-speed, rpm, temperature and fuel level when light control is at off or drl (driving lights) position. I went to dealer and service man said that is the way it is and another new vehicle on their lot was the same. The gauge lights are on but dim in parking and headlight position. (Toyota manual says use drl in daytime to save fuel and eliminate chance of burning out driving lights. ) I called Toyota and they said after 2 weeks of investigation that this is the way it is. This is a safety issue because we cannot see the speed on cloudy days or with sunglasses on sunny days. My previous Toyota- 2006 Sienna and 2013 avalon have illumination anytime the ignition is on for driving. When you can't see the speed easily, this is a safety risk- there is no digital display of speed on this vehicle.
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.
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.
The contact owns a 2012 Toyota Sienna . The contact stated that while traveling 30 mph, the headlights failed to fully illuminate the roadway. The vehicle was taken to the dealer. The manufacturer was contacted. The vehicle was not repaired. The failure and current mileages were 400.
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.
The right side headlight assembly is accumulating moisture and condensation inside which causes the headlight to fail.
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.
My concern is the dead zone created by the head lights on my car. The projection of the headlights on my car are extremely dangerous due to the dead zone in front of the vehicle. The headlights have been adjusted multiple times and the dealer response is" that is just the way these new headlights are". On dark roads it is highly probable that an accident may occur because you cannot see where you are going and if there is a slight curve to the road it is impossible to tell which way the road is going. On my last trip at night we had 3 occasions that if we had not flashed the high beams we most certainly would have have a wreck.

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.
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!.
The contact owns a 2011 Toyota Sienna. The contact stated that the visibility of the headlights was not projecting far enough. The contact took the vehicle to the dealer and the dealer made some adjustments to the headlights but to no avail. The contact stated that the vehicle was unsafe to drive at night. The failure mileage was 8,000.
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.
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.
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.
