OEM high beam bulbs continuously explode. I'm not saying they just burn out, these bulbs shatter, and send shards of glass on the inside of the headlamp housing. I believe it's a big safety risk, because for me, it happened while I was driving late at night in the dark where there are deer nearby. Brights are essential to see far and when you're driving through hills, going up a hill you need your brights to extend higher than your normal lights do. This is a commonly complained about problem for the 2008-2010 models of this Toyota Avalon. Toyota has issued a technical service bulletin back in 2011, but it is a major defect and I believe it should be fixed regardless of whether a customer pays for a warranty or not. A mechanic told me also that they are not sure why Toyota has not warrantied vehicles with this issue. The solution is replacing the headlight housing. …
Because my instrument panel is alway illuminated, I was unaware that I was driving one night without my lights on. Now I know why I see more cars at night without their lights. Manufacturers need to fix this problem. Older cars would not turn on the panel lights if the headlights weren't on. You would think this would be an easy technology fix with since we have self driving cars now.
Took my car to the local dealer too have headlights looked at because a police officer pulled me over for "no headlight passenger side". When I turned the lights on for him, it came back on. Then I found both high beams burned out and the drl's also did not work. So, off to the dealer. They found both high beam bulbs exploded, and could not reproduce anything else / find any other problem. They removed the high beam bulbs but neglected to inform me. Now after some research I found out these problems are known to Toyota. They extended the warranty to 72,000 miles, but, would not cover my car that I bought from them with 82,000 miles on it... My car now has 97,000 miles on it but nothing does me any good when the lights go out crossing the rocky mountains in the middle of the night... Talk about a aha moment. It is a complete safety issue wether they admit it or not.. …
2008 Toyota Avalon. Low beam on drivers side goes out intermittently. Have to turn headlights on/off quickly. Was pulled over by chp on highway, told him just had low beams bulbs replaced. He asked me to turn them off, then on and both lights were working. This was in spring 2018 approx 80,000 miles. Took to mechanic, they worked fine. Did not have a problem for about 6 months after that, now afraid to drive at night as it happens more frequently and afraid that lights will not come back on. So many of same complaints on forums. I emailed Toyota and actually got a call back but gal stated they had no record of any complaints regarding low beam problems. She gave me a case #2008070658. Asked if I had taken it to dealer but they would charge for diagnosis, I told her I would not be doing that. …
Toyota sent out a warranty enhancement notice about June 2012 that if you had problems with high beam headlights on my model vehicle to take the car to a dealer. Car had to be less than 5 years old a under 72,000 miles. I ask about my car and they said my mileage was to high. Within a month I found out what the problem was. The high beam bulbs would explode as mine did. I went back to Toyota to ask for a waver for the repair to be done. They again said no. But would be happy to repair it for $2284.66. The cost of new headlight assemblies. It seems that the original bulb was no longer made and there was no direct replacement for it. Solution was the $2284.66 repair. I believe this is a safety issue and should be covered no matter the age or miles of a vehicle. There was no mention in the notice of bulbs exploding or that the entire assembly would need to be replaced. …
The high beam lights are known to explode on some 2008 and 2010 models. My high beam lights exploded with 66,000 miles on the vehicle. This problem happened while my vehicle was in motion. I routinely drive in an area with a heavy deer population. I cannot see these hazards at night with out high beams. Toyota had an extended warranty on this issue (5 years, 70,000 miles). Since my car is over warranty in years but not miles, Toyota refuses to replace the headlight assemblies. They are telling me the cost will be over $2,000. I consider this a safety hazard and am very upset that Toyota will not fix this problem on my $40,000 top of the line Toyota. I am filing this complaint to the dot, ntsb, and attorney general. You can contact me at [redacted].
When coming back from a short trip I noticed that the right side low beam headlamp was out. Then one day the light was on again then the next it is out. Now it rarely comes on so I.called my Toyota dealer and they said it would be at least $200 for new low beam light bulb. I then took it to a reputable repair shop and they said that the bulb was not bad but the ballast was bad. They showed me a list of complaints from on line and they said there was a recall for that problem. Toyota says there is no recall. If this is such a common and expensive problem there should be a recall. I researched several web sites and there are numerous complaints about headlight problems on the 2008 Avalon. Some problems exactly like mine others a little different but all are about malfunctioning headlights.
I have been pulled over numerous times due to having a headlight out. However it's never blown. Once I show the officer by turning the lights off for a few seconds then back on the light is on. From reading many Toyota forums and going to a Toyota dealer, it is a faulty wiring system and to repair it will cost at least $1300.00 or more. It is a hastle as well as a safety hazard. The light doesnt stay on once turning the lights off then on. Within a few miles it goes off again and it is constantly blowing the light bulbs. In the 3 years I have had my car I have replaced the lights at least 7 times. The light will always be off when I start my car with the remote starter and when I start it with the ignition if it's on, within a few miles of driving it goes off again.
Just about every time I drive the vehicle at night, one or both headlights will go out. In order to get the light or lights back on, I have to turn the lights off and then back on. This presents an ongoing potential hazard, especially when they both go off at once. This model is the top of the line (limited) and has the HID lights. I have read on line that I am not the only person who has experienced this problem. I further understand that Toyota May have an extended warranty for this issue. This is a serious problem that could result in an accident if both lights go out and I am not able to get them on again while I am traveling on an unlit road. This last happened yesterday as I will indicate below but it has been happening for more than a few years now.
While driving straight ahead at night on a highway the high beams suddenly went out and would not go on again. I switched to low beams. I later learned from a mechanic that there is a design flaw or inferior microprocessor controlling the headlights and that the low beams could also suddenly go out while in motion. This is a severe safety issue. The Toyota corporation will not stand by their product and have referred me to a Toyota dealer that wants over $2,000.00 to fix the safety issue. There should be a recall on this. I believe it only affects the 2008 Avalon models. There are even several articles on the internet relating to this problem. I have nothing to download as I did not get a written estimate, only a telephone quote, from the Toyota dealer.
