2019 Toyota Avalon: engine stalls while driving

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.

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.*

While driving on the road the vehicle will stall as if it's not getting any fuel. When the vehicle is parked and turned off I can hear the fuel pump running.

My car mostly parked in the garage. Lately, it's getting worse and noticing engine running rough, stall at speed about 20 MPH and humming from under rear of the car hours after it's shut off.
