2019 Toyota Avalon

While driving the vehicle and stopped at a red light or stop sign, the vehicle failed to accelerate when pressing the gas pedal. I pulled to the curb and turn off the car. After I start the car again, it will work fine. The vehicle has failed to accelerate several random times while driving and stopped at a light or stop sign causing a hazardous situation. The last time it occurred was on September 1, 2026. It has happened three times prior to this date also. No vehicle codes or warnings lamps were displayed on the dashboard at any time.

UA80 transmission issues. High pitched whining Erratic and hard shifting shuttering and hesitation Issue has been diagnosed by dealership Toyota Technician and independent service center ASE Certified technicians. Car is still drivable, with no warning lamps as of yet. Issue became more noticeable after I had the transmission fluid changed by dealership.

The transmission needs to be replaced. My car has 75,146 miles and my check engine light came on while I was driving down the interstate. I took it to the Toyota dealership and they confirmed that the transmission needed to be replaced. I was told it would cost $8,600. I was looking for any recalls on my car and saw there were multiple lawsuits involving the transmission in my car and other Toyota and Lexus models. The primary lawsuits involve millions of vehicles equipped with the UA80 8-speed automatic transmissions.

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.

I bought the car new in 2019. Car was fine for the first 2 years then it started skipping the gear on low speeds, it does not happen all the time but it does seems to jerk while changing gears in low speeds, occusionally. I have taken the car in to Toyota in Green Bay, WI location and I was told they can't duplicate the issue.

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.*

I BOUGHT THIS CAR ABOUT 5 MONTHS AGO AND EVERYTHING WAS FINE UNTIL A MONTH AGO. EVERY TIME I'M DRIVING LESS THAN 35 MPH I FEEL A ROUGH DOWN SHIFT IS NOT THAT BAD, BUT I NOTICE IT. IT ONLY HAPPENS WHEN I'M DRIVING SLOW, MORE SPECIFICALLY IN THE CITY.TOYOTA HASN'T SENT ANYTHING REGARDING THIS PROBLEM. I THOUGHT IT WOULD GO AWAY BUT IT HASN'T.

THESE ISSUES OCCUR CONSISTENTLY WHILE DRIVING ON A LOCAL SIDE STREETS AT LOW SPEEDS, BETWEEN 0-35 MPH. (1) WHEN EXECUTING A STOP AND GO EITHER AT A STOP LIGHT OR A STOP SIGN, MY 2019 AVALON XLE EMITS A "JERKING" MOTION BEFORE IT DECIDES TO KICK INTO GEAR. THE "JERKING" CAN EASILY BE FELT INSIDE THE VEHICLE. THERE ARE MULTIPLE DRIVERS EXPERIENCING THIS "JERKING". I THOUGHT THE "JERKING" WAS OCCURRING WHILE THE VEHICLE WAS WARNING UP, BUT "JERKING" OCCURS AT ALL TIMES. (2) WHEN TRAVELLING AT 30-35 MPH, AND AFTER RELEASING PRESSURE OFF THE ACCELERATOR, THE VEHICLE FEELS LIKE IF THE BRAKES ARE SLOWLY BEING APPLIED INSTEAD OF COASTING DOWN THE STREET. I BELIEVE THE TRANSMISSION IS DOWNSHIFTING IN SUCH A WAY THAT IT FEELS LIKE THE BRAKES ARE BEING APPLIED. THE ABOVE ISSUES HAVE BEEN OCCURRING SINCE PURCHASING THE VEHICLE WITH LESS THAN 10 MILES ON THE ODOMETER. I WAS TOLD TO WAIT FOR A TOYOTA SERVICE BULLETIN TO BE PUBLISHED, BUT I DID NOT RECEIVE ANY GUARANTEE THAT SUCH A BULLETIN WOULD EVER BE PUBLISHED. I HAVE FILED SEVERAL CASES AT TOYOTA HEADQUARTERS AND WAS TOLD MY CASE WOULD BE REVIEWED BY THE TRANSMISSION ENGINEERING DEPARTMENT. AGAIN, NO GUARANTEE THAT THE TRANSMISSION ENGINEERING DEPARTMENT WOULD EVER REVIEW MY CASE. AND I HAVE NOT RECEIVED ANY RESPONSES OR FOLLOW UPS EMAILS FROM TOYOTA HEADQUARTERS RE: MY 2019 AVALON TRANSMISSION ISSUES.
