Multiple warning lights suddenly appeared on the dash while stopped at a traffic signal. (Photo attached) Note: the photo does not show the red "PCS" light which was flashing. I was able to get off the road safely although the brakes did not feel normal. Had the car towed to Capitol Toyota in San Jose the following morning for repair. They diagnosed the problem as a failure in the Master Cylinder Booster Unit and replaced it. Note: the attached invoice misstates the issue as "check engine light" which is incorrect.

In the 2013 toyota avalon, driver visibility is dangerously distorted when looking through the rear view mirror at approaching cars (especially at night), due to a defect in the new 2013 engineering design of the rear glass material, rear glass contour and angle, tinting, and defrost strips. All lights (especially vehicle headlights, street lights, traffic lights, etc.) observed through the rear glass have long, bright, vertical lines radiating at the top and bottom from the main light source viewed through the rear view mirror. These vertical lines shining from all of the numerous light sources obscure the rear view vision, causing confusion for the driver in many ways: 1) not being able to correctly judge rear car distance, 2) not being able to identify the types of vehicles in the rear, 3) not being able to change lanes safely because of distortions through the rear glass panel, 4) not being able to judge how many vehicles are approaching and/or passing, and last but not least, 5) causing the driver to stare longer through the rear view mirror in an attempt to discern what is taking place behind which takes the driver's eye off of the front vision for too long. Although the bright vertical lines can be seen more distinctly at dusk and night, they are also observable during the daytime if the vehicles coming from behind have front lights on, and/or the sun shines on the chrome. These radiating vertical lines take on the color of the main light source seen from behind so the driver may observe white, yellow, red, green, etc. Colors. This causes confusion when trying to judge what is happening with approaching vehicles from behind. On a multi-lane highway at night, these many-colored vertical lines radiating up and down from the various types of headlights, street lights, etc. Cause a confusing and dangerous situation for the driver.

Left headlight works for only about five minutes then turns off but turns back on right away if I turn off then on all lights dealer replaced light in august 2011 but within a few months same problem is occurring. Return to dealer got only a denial of any "ongoing" problems reported (edmunds says otherwise from many irate toyota owners). Dealer only offered to replace the built again ($178.00) or "charge labor to ck the full electrical system (ignoring that only the headlight electrical assembly need be checked and that the assembly can be replaced for around $300.) dealer really wants to ignore the problem and just sell more bulbs. This is likely my last toyota (after having four.)

Have had intermittent problems with headlights going off. The last incident that occurred was while driving one night at around 70 MPH.. All lights went off! We were able to safely pull over and turn lights to off and then back to on. Were able to get low beams back on but not the high beams. Later discovered at the dealership that both high beam bulbs had exploded. We have been told by dealership and an insurance adjuster that this is a design problem with our model/year of car which is a 2008 avalon. Still fearful that we could have similar issues with the low beams. This is an urgent safety issue! In addition, we have been told that the cost to replace the headlight assemblies would run around $2500.00! We are lucky that we are under extended warranty.

My 2008 toyota avalon had the high beam light fail after approx. 30000 miles. I took it to the dealer and told them the high beam did not work. I was insulted when they asked, "what do you mean they don't work"? I told them, "they don't turn on". I was told they both burned out and I said there was no way they would both burn out at the same time. Their insults continued with, "their the same age so they certainly could burn out at the same time." I explained when I went to turn them on one night, all lights in the car went out and I heard a pop sound. I was able to get the regular lights back on but the high beams have never come on since. After they checked the car I was informed, "they didn't just burn out, they blew up". Even with their statement the dealer would not admit to any electrical problems with the car. They were going to charge me $250 per light. With their attitude, I didn't get them changed. I made another mistake with this dealer when I got the oiled changed several months later. Toyota now provides a bogus safety report. My report stated all the lights worked. It also stated my rear window wiper was in excellent shape and didn't need to be replace. If you've ever seen an avalon, it doesn't have a rear window wiper. I guess the virtual one works just fine.

On our 2010 toyota avalon we have had all the lights on our dash go out for a period of 10 seconds or so on 2 different occasions while we were applying the brakes and making a turn. The dash lights on all our gauges go out and come back on there own. The brakes continue to work and no harm was done to anyone, but when we took it back to out dealer they could not make it do it when they checked it out so they simply returned our car back to us without any further investigation. We are concerned because this isn't normal. Is there something wrong with the electrical system on this car or something to due with the computer system?
