Electrical System Problems of Toyota Avalon - part 1

I purchased this vehicle as a preowned used certified from the Toyota dealership the car has broke down 4 times for the same exact issues all the lights will come on and it will say take to the dealer for service June 8 2024 purchased the car. November 2024 in the shop ( sensor ) December 2024 in the shop ( sensor ) no charge July 8, 2025 car had to stay overnight ( ignition coil $300 ) service told me the mechanical warranty expired in June. 8 days later July 17, 2025 broke down on the highway I was stranded for 5 hours had to pay for a partial tow out of miles. Its been 6 days no car. I dont feel safe in this vehicle and I think it has a defective system. I am locked into a contract with a vehicle that keeps breaking down. I have called the lemon law and they said my car is too old for a claim but not considered new by 1 year. I need some help, I have reached out to Toyota corporate and I am waiting to see what they plan on doing. I have been stressed out since my last breakdown with this car. By the way I have only put 4000 miles on it since I purchased it. Going on a road trip is out. I no longer trust this vehicle it just cuts off for no reason once the dashboard lights come on it just stops. I cant imagine having my grandbabies in that car its scary. Car is still in the shop its been 6 days now.

When starting the vehicle, an extremely high pitched noise is emitted from the speakers. The safety of my young child is at risk every time I start the car because this could cause irreparable hearing loss. This is a known issue across many Toyota models as I've found through online forums. Toyota wants $1,200 to fix the dcm module when it is a manufacturing issue and not caused by the consumer.

After troubleshooting, the issue with my car cannot communicate with my mobile app through Toyota remote connect, cannot update vehicle software, and after a $130 diagnostic fee, the dealer states the dcm module is bad and needs replacing. My question is this is a safety issue, correct?.

The car emitted a very loud, high pitched sound, lasting several seconds when starting the vehicle, which was very painful. At the same time, red and green lights are seen flashing a few times next to the sos button. This has happened twice in the past month.

2019 Toyota Avalon xse with 41,400 miles. Complete failure of the climate control panel. No buttons or lights would work, resulting in lack of any fan, heat, air conditioning, window defroster, mirror defroster or seat heat. Found no fuses blown. On one occasion since then both seat heat lights came on indicating full heat but did not produce any heat. Two days later panel began to work normally for a 1 hour drive. Later this day there was another complete failure of the same panel. Took car to dealership the next day and panel functioned normally enroute. When dealership diagnosed the problem the climate control panel had failed again and the problem could not be duplicated. No trouble codes were stored in the system. They performed a master reset of the system thinking an update may have been corrupt. Panel worked when leaving the dealership later this day. The next morning the panel initially did not work, but 20 minutes into a 1 hour drive it started working normally. That evening the panel failed again on vehicle startup and has not worked since. Took it back to the dealership this morning and did not turn vehicle off, thinking the failure might show up in the car’s system until the service advisor could drive it to a maintenance bay. After 3 hours the problem could not be diagnosed. The lead mechanic contacted Toyota corporate to inquire if this problem has been encountered previously and for a possible solution. Overall this may not be a safety issue warranting any further action. However, if the windows or mirrors were to fog up, there would be no defroster capability for either of these. In this situation it could quickly become a dangerous situation while the vehicle is moving. This should be investigated further.

One of my airbags or out. My heated seats on my passenger side heats up on its own . I also have lots of water on my passenger side floor when it rains. My gas pedal seem to get stuck when taking off.

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. So there is clearly a material defect, and I believe it affects safety. Vehicles are required to have high beam headlights for a reason, and the high beams on this vehicle burn out commonly on certain vehicles, and replacing bulbs does not solve the problem. It is a very expensive repair as well. What kind of car manufacturer doesn’t recall or acknowledge a material defect or design flaw in such a crucial safety feature or a vehicle such as headlights? it’s an expensive, annoying, and dangerous issue that continues to happen. There are so many complaints about this high beam issue for the 2008 year. In my mind this really reduces Toyotas reputation and credibility since they did not and will not recall these headlights. We just have to deal with their faulty design. Fix your mistakes instead of making customers foot the bill for your poor craftsmanship. This is pathetic.

The sunroof of my 2019 Toyota Avalon is defective. It is available for inspection upon request. My safety, as well as the safety of my passengers, has been put at risk. My problem has been confirmed by sheehy Toyota of fredericksburg. No warning lamps or messages to indicate sunroof problem. The driver side of my sunroof keeps clogging. I first took my vehicle to Toyota sheehy of fredericksburg on 1/3/2023. Sunroof tray was found to have a buildup of organic detritus, causing drains of sunroof tray to be clogged and allowing rainwater to spill over into interior. Sheehy technician cleared the sunroof tray and drains of organic material. Drains were now flowing properly. Technician claimed that sunroof would not have to be drained for at least two years. There was standing water and a heavy mildew smell in the car. Sheehy refused to clean/drain carpet of water. I took it to a detailer and had the detailer vacuum and clean the carpet. Less than a month later, I started experiencing the same issues -- wet carpeting on the floorboard. I took my vehicle to sheehy Toyota of fredericksburg on 2/7/2023. Technician told me that the driver side of the sunroof was clogged. Technician claimed that he fixed the clogged drain of the sunroof. Technician suggested that my sunroof got clogged because I have only driven my car 140 miles this month. Not a rational explanation. He recommended that I replace the carpet due to mold concerns. Why would I replace the carpet if there is a strong possibility of having wet carpet every few weeks? technician insists that wet floor is not coming from any source other than the sunroof. I suspect that my sunroof is defective. I should not have to worry about wet carpet in my car everyday that we experience rainshowers. Sheehy Toyota insists that nothing is wrong with the structural integrity of the sunroof and that external factors are to blame.

Purchased car used 11/2020 Jan 14 2021 had 2 open recalls steering casting defect and wire harness filter to deflect noise from ecm . I lost control of communication of operations. 12/2022 steering lock bar the past 2 years uncovered everything on my own. Learned somebody died in 2003 Avalon in texas about steering locking up. Plan to talk to class action lawyers over airbag and steering. And arrange my own lawyer with settlement lawyers to make this repair and all TSB to be performed. I will never buy a car unless I can find all TSB problems associated with that car. I hope recalls can be opened especially when you guys in government state safety ,compliance and emissions do not expire. Recall.

Leaving a parking lot, the car jumped out of gear. Thought maybe I had bumped the gear selector but attempts at putting the car in gear resulted in grinding noises and the only option was to put it in park. Check engine light came on. Mechanic diagnosed a speed sensor. Had this happened on the freeway or while trying to pass another car on a two lane and a speed sensor disable the entire car to me is dangerous and should be addressed. Had the check engine light come on, I would have had the sensor replaced right away. I now feel this is an unsafe situation that could arise in other 2017 Toyota cars.

After starting car, from being parked in parking garage from 8am-5pm, the pre collision warning system light turned on. Vehicle currently has 20k miles on the odometer. There are numerous records in the car's onboard history of this device failing during car startup. Drove home, started next day with no incident. System is unreliable. According to the infotainment system, the car seems to report the failure every few months.

A year ago my 2019 Toyota Avalon started displaying a message that the rcd (rear camera detection) was unavailable. I tried working with the dealership that sold me the car, but they ignored me. I went to another Toyota dealership and they said it would cost approximately $2000, but could not guarantee it would fix the issue. I’ve seen online that 1000’s of Toyota owners with the same system have had similar problems, and Toyota frequently responds with, “it’s a rolling computer, and very advanced. ” some were fixed by recalibration, but many have a more serious problem. All the stories are only the people that have posted about it. It’s probably Toyota’s biggest problem. My car was under warranty when it began, but health issues and restrictions kept me from getting the attention of the general manager since I was ignored by others. I feel this is serious enough and has effected numerous people that it warrants an investigation. People are relying on a system that doesn’t work properly, and some have been hurt and many others will be negatively affected by it.

Turn off the lights inside panel. The level of heat all the way up, the same with the gasoline level. The internal lights blink. Loss of power.

Driver and passenger side headlights suddenly stopped working. , discovered that both light bulbs had shattered inside the head lamp housing. Dealer & Toyota USA confirms that Toyota has changed the headlight housing design that accomodates a different high beam bulb that will not shatter. Toyota refuses to replace the housing even though vehicle only has 60,000 miles on it. This is a serious safety issue that needs to be elevated to recall status. Toyota used, a now expired, extended warranty to avoid this being a recall as it should be. How many affected vehicles have to lose day time running lights and high beams!.

Headlights flickering constantly and at times one or both will go completely off. Will have to manually turn off and then turn on again. Both will shine steady for about 2 minutes and then began to flicker again. This happens when parked or when in motion. This only applies to when the lights are on low beam. (this has been happening for a few months).

I have a electrical issue going on with the driver side headlight. I have had to change the headlight over 3 times now . Seems to go out with in a month or two. While doing my own research Toyota has also changed the light bulb for the old owner more then 3 times. It has only been the driver side headlight that is being affected. I'm a lil worried that at any time a electrical fire or something else bad will happen. So at this time I haven't had new bulb installed. I'm just to nervous. So it's hard at times to see at night fall when driving.

This vehicles blind spot monitor on the passenger side is not operational and does not show vehicles in the blind spot on the mirror over 70% of the time giving the driver a false sense the lane is clear. It appears the system gets worse the longer you drive and almost no usable when driving over 40 miles. The driver side blind spot monitor system works as it should. Upon some research on line, it appears this is a common issue and Toyota indicates it works to specs, but based off the factory manual does not.

Please check for all recalls on my car.

02/06/2020 NHTSA complaint: 2013 Toyota Avalon hybrid limited, rear window sunshade assembly failure, complete and total, in the 'up' position and/or in the �down� position. When stuck up, the failure obstructs rear view at nighttime. This is a serious safety issue. The sunshade is designed to automatically retract into the 'down' position when the car is put in reverse, but if this failure has occurred, the sunshade will make a loud grinding sound for about 15-20 seconds while the sunshade attempts (and fails) to retract into the 'down' position. It will also make the sound even if the sunshade is already retracted. If the shade is already down/retracted and I shift from park to reverse, the grinding noise starts immediately, and the shade does not move (go up). But if I press the activate button, the shade will start to extend, and if I can press the activate button again before the shade is fully extended, it will retract (and begin another 20 second cycle of grinding) and stay down. While stopped or in motion, pressing the activate button raises the shade (if it was down or retracted), but not without the 20 seconds of loud grinding noise. If the shade is up/extended and you press the activate button, the shade will not retract/go down, but the grinding noise will begin. If the shade is up/extended the only way to make it go down is to press the activate button and, while the grinding noise is present, simultaneously go to the back seat so you can reach the shade and manually push one of the vertical bars toward the center; then the shade retracts fully and continues grinding for another 20 second cycle. Not only is this a safety issue, but it is continuous and the grinding noise is incredibly annoying.

2014 Avalon hybrid - air conditioning blower switch/motor need replacement. Total cost $980. 00. Not covered under Toyota warranty or additl warranty. Service technician stated this is rear for Toyota - but did not offer any assistance. The air conditioner works when the car is moving , when it stops it blows out hot air. . This is very uncomfortable when living in florida with the average temp 99 degrees and up. This is my first time in 50+ years replacing a blower motor for an air conditioner in my car-I thought Toyota was the best of cars. I am very much disappointed. Frustrated consumer,.

Tl the contact owns a 2006 Toyota Avalon. While driving less than 5 mph to pull into an underground garage area, the accelerator pedal became stuck and failed to release. The brake pedal was applied with force, but the vehicle lunged forward and crashed into the garage door. Upon impact, a yellow piece associated with the front passenger side air bag fractured. None of the air bags deployed. The driver sustained injuries to the head and neck and sustained bodily scratches and bruising, which did not require medical attention.

The vehicle was not included in NHTSA campaign numbers: 10v017000 (vehicle speed control) and 09v388000 (vehicle speed control). The manufacturer was notified of the failures. The vehicle was still at the contact's residence. The approximate failure mileage was 216,000.

Headlights and fog lights go off while traveling. May or may not come back on when switch is reset. They go off unpredictably and may be at a very inopportune time causing collision.

Reported this to dealer. They couldn't find anything wrong at the time. Keeps happening : blind spot monitoring and cross traffic alert malfunction alerts.

Leaks. My stereo system shorted out due to leaking water from windshield area. I since learned Toyota knew about at least 2 leaking problems (in TSB’s) however the coverage was only for 36,000 miles or 36 months. I didn’t detect these issues until after that time. Now it will cost thou$ands to remedy.

Rear sun shed break very fast makes a lot of noise. It can't be disabled without causing other problem such as engine light on and cruz control disabled and all kind of sensors that need to be replaced. Its very dangers and frustrating.
