Brake pedal became hard and vehicle was difficult to stop. ABS warning light appeared on dashboard. This is a problem that Toyota has addressed previously by extending the warranty period to 10 Years/150,000 miles. My vehicle has 122,000 miles on it but the 10 year extended warranty has expired. I took the vehicle to a local repair shop and they confirmed that there was a problem with the brake actuator assembly. Now, Toyota says it would cost over $3000 to remove and replace their already defective part.

In 2025 I decided to clean the hybrid battery fan. I removed the side panels and found that the fan to battery duct had never been installed. I am the original owner and no one had ever removed the inside panels or had reason to remove the duct. This has likely resulted in the overheated battery which now needs replacing even though I have only 161,000 miles on this car which I have always maintained without fail regarding oil changes and other maintenance tasks.

The ABS brake booster/accumulator is going out and this has been a known issue with Toyota for years. Mine was purchased used a few years ago and had no issues until recently, as the pump is running more frequently.

Trunk lock will not unlock or allow opening, back latch malfunctions, when car battery dies or car looses powerã⢠you cannot open the trunk and access emergency tools/equipment and battery to jump car. â¢ãYou have to access by climbing through the front of the car if you are able-bodied too. There is no opening handle from the inside of the trunk to be let out, scariest and one of the most important major safety concerns, theres no emergency exit from inside vehicle. Water/snow/ice also falls down into the vehicle when opening hatchback, it slides inward from hood of car or slides back from rear windshield and door, causes water to be pooled up in my battery compartment.
