What GTA Drivers and Used Car Buyers Need to Know
Toyota has long been known for reliability, but a growing number of lawsuits in the United States are raising serious concerns about certain Toyota and Lexus vehicles equipped with the UA80 eight-speed automatic transmission.
A new class-action lawsuit filed in New Jersey claims the transmission suffers from overheating and premature wear — potentially leading to costly failures for owners. With hundreds of thousands of vehicles on the road using this transmission, the issue is getting major attention in the auto industry.
Here’s what drivers and buyers should know.
According to the lawsuit, the UA80 transmission can generate excessive heat, which may burn the transmission fluid and cause premature internal wear.
Drivers have reported problems such as:
✔ Harsh or delayed shifting
✔ Slipping gears
✔ Burning smell from transmission fluid
✔ Delayed engagement when accelerating
✔ Unusual noises
✔ Sudden loss of power
✔ Vehicle stalling or failing to stay in gear
Some complaints also point to software issues and defective torque converters that cause early upshifts and poor performance.
The lawsuit argues these problems are dangerous because a failing transmission can cause unpredictable vehicle behaviour — especially while driving at speed.
The legal action claims many popular Toyota and Lexus models may be impacted, including vehicles produced from 2017 to present.
Commonly listed models include:
Toyota
- Highlander (2017–present)
- RAV4 (2019–present)
- Grand Highlander (2023–present)
- Camry (2017–2024)
- Sienna (2017–2020)
- Avalon (2019–2022)
Lexus
- ES 250 / ES 350
- RX 350
- NX 250 / NX 350
- TX 350
These are extremely popular vehicles — especially the RAV4 and Highlander — which means many drivers could potentially be affected.
Some owners have reported transmission failure at relatively low mileage, and replacement costs can reach $9,000 or more if the vehicle is out of warranty.
🔧 Why This Is Becoming a Bigger Issue
Technical service bulletins about this transmission date back several years. The lawsuit claims these bulletins show the manufacturer knew about the problem but did not redesign the transmission.
Because many of these vehicles are now aging out of warranty, more owners are experiencing failures — and more lawsuits are being filed.
Even if only a small percentage of vehicles fail, the total number could still be very large due to high sales volumes.
💡 What Toyota Owners Should Do
If you own one of the affected models, consider the following precautions:
✔ Change transmission fluid more frequently than the standard service schedule
✔ Pay attention to rough shifting or delayed acceleration
✔ Address warning signs immediately — don’t wait
✔ Check warranty coverage or extended warranty options
✔ Get a professional inspection if buying used
Early maintenance may help extend transmission life and prevent major repair bills.
