Toyota Avalon stalling problems

Filed Oct 4, 2026 · Transmission · WA

What component or system failed or malfunctioned, and is it available for inspection upon request? Transmission. Yes. How was your safety or the safety of others put at risk? The UA80 eight-speed automatic transmission used in my Toyota is defective. There is a design flaw that causes excess heat inside the transmission to burn transmission fluid resulting in premature transmission failure as well as stalling and other dangerous situations. I also noticed significant noise from the vehicle’s transmission assembly. In addition, the engine RPM jumps high while the car struggles to accelerate or temporarily loses power. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? The check engine light came on a week ago, but no symptoms were exhibited at that time.

A couple of months ago, my car started running a little rough as it would sit in idle mode. When suddenly my check engine light came on. I checked the codes and they seemed to be P0445 Evaporitive emission system leak detected (large leak). And P0441 Evaporative emission system. Incorrect Purge Flow. P0505 Idle control system. And P0171 System to Lean Bank 1 and P0174 System to Lean. Bank 2 and P0172 System Too Rich and P1170 and P117B Manufacture Control. But other then just running a little rough at idle that was about all that I had noticed until I went to go fuel up back in October. My fuel was low so I went to fuel up and after wards, my car struggled really hard to start. And every time since that days it’s progressively gotten worse. Last week I kept my car running while I fueled up and as I drove away from the gas station, my car just stalled out completely. It took me about an hour and a half before my car would start again. I was waiting for the tow truck to come get me and thank God inc checked it one more time and it started. Now just recently, when I put my car in park the engine immediately Reva up super high. It started to wine really loud and rpm go through the roof. Until I shut the car off. So I am unable to sit in idle at all anymore. I decided to Google what could be going on with my car and then I seen this recall on the fuel pump off some Toyota Avalon 2019 & 2020 models. But much to my surprise, my Vin/Vehicle is not listed. Will Toyota still replace the fuel pump for free? Please contact me as soon as possible. I really need to address this issue. Thank You!

On october 28, 2020, toyota announced it was conducting a safety recall involving certain toyota and lexus vehicles produced between july 2017 through december 2019 due to the same fuel pump issue for which they announced a safety recall in january 2020. The referenced vehicle door sticker shows a production date of 12/19, which is within the production period announced on 10/28/2020. However, the VIN on this vehicle does not appear on any recall list and the dealer tells me there are no recalls for my vehicle. Nonetheless, I have experienced several instances where the vehicle feels like it is about to stall: when making a turn or driving on city streets; in some instances (including today) it is when starting from a stop sign or traffic light; other times it is when accelerating. There have been two instances where this happened while making a left turn at an intersection. In one such instance, a yellow triangle warning light flashed momentarily on the vehicle's display. This issue was reported to the selling dealer during the last routine maintenance visit on may 4, 2021. In reference to this complaint, the dealer work order reported technician "was unable to duplicate customers concern at this time vehicle is currently operating within all manufacturers specifications".

My vehicle is equipped with a low pressure fuel pump which may stop operating if this was to happen the vehicle will stall and not be able to restart and if it happens while driving on the interstate which I drive 45 mins one way to work daily then the car will lock up and I wont be able to move it and could cause accidents to where the vehicle could explode and toyota has no idea how to fix it and its been sitting since oct 2020. I have contacted their corporate office and the dealership in which neither are willing to work with me in regards to payments being exempt till they know how to fix my car. They said its either I wait it out till they know or trade it in for an equal trade. My issue here is the car has lost equity in it so the new loan would probably be upside down on the ltv which is costing me, they pull my credit which would make it go down, dont get me wrong its loan worthy but why should I have to go thru all this red tape when they are the ones who caused the issue by selling a lemon to customers. Why do I have to continue to make payments on a car that I have only owned since may 2020 and has been sitting since oct that I can only look at ...I mean how long does one have to payout without getting anything in return? This cannot be legal for them to continue to charge people for products they cant use??? I love this avalon and it is top of the line with the extras so I am completely happy with it but toyota is not being fair. They have given me the rental car so I dont loose my job but that is something they should do for god sakes. And that doesnt have anything to do at all with the payments I have to pay on a car I can only look at for the last 4 months...please help me thank you in advance.

When starting the car and proceeding to accelerate the car stalls. There have been several incidents where the car has done this (each time being taken to service at toyota). One in particular almost being hit by a truck when going from a red light to green light.another one turning out of a parking lot and having to make sure there was absolutely no cars coming my direction in fear of being hit while turning and car stalling. These issues have been too many since I have purchased the car. This matter has been taken up to customer relations and reviewing how many times I have taken this vehicle in they continue to tell me that they have not failed to repair my car. I have continued to take the car to be serviced and diagnostic comes up with no problems in the computer system. *I also have videos and all of my service invoices regarding the stalling issue that has yet to be corrected.*
