Loud popping, grinding, and clicking noises from the front left of the car while decelerating, sometimes during acceleration, and parking. The clicking has been happening since the vehicle was new and has progressively gotten worse. It is so bad now that other motorists and pedestrians become distracted by it. A pedestrian tripped and fell over last week trying to look behind them at what was causing this unusual racket. I can now feel the repetitive popping in the steering wheel and brake peddle. The car now feels unsafe to drive. I have taken this vehicle to several Toyota dealers in 2018, 2019, 2020, and 2021 to expressed my concerns. Dealers insist the characteristic is normal, even when T-SB-0157-18 "Click Noise From LF Wheel Area During Deceleration" was in effect. The vehicle is still under powertrain warranty and no warranty repair has been offered each time. This characteristic was very similar to T-SB-0157-18, however it has gotten worse. It now always occurs during deceleration, frequently during normal driving and acceleration. It is extremely distracting and nerve racking, to the point of it being a safety issue for me, other motorists, and pedestrians. It is a very unusual sound no one expects and pays an unsafe amount of attention to. I strongly suspect the front CV axle(s) are grinding themselves into dust. Toyota knows this is a safety issue, cancelled the TSB in April 2019, and refuse to repair the car under power train warranty. My axle has been clicking since March 2018. It now feels unsafe in February 2022, especially after this most recent tripping incident.

I lost power on overpass. Hybrid malfunction light, collision light, engine light all came on. Almost matching recall, but Toyota service told me it's a module and would cost 1200$ to fix. I told them no. Charged me 144$ and I erased code, with no problem since" Toyota does not care and I complained"

Just five minutes after I left the house, I was driving at 15 miles mph on a curved road and the vehicle completely lost power. This includes both the electric motor and the gas motor. Both the steering system and brakes malfunctioned, causing the steering wheel to become too stiff to turn and the brakes were not able to be pressed down no matter how hard I tried. This caused the car to swerve off the road and hit a light pole. Not only did the automatic collision prevention system failed to work, the airbags also failed to deploy with the amount of impact. This has caused severe damage to my car and severe injury to my body. Unfortunately, this was not the first time the vehicle experienced a power failure. The first time I was in stop and go traffic on the freeway. The car completely shut off for 5 seconds and turned backed on again. Luckily the vehicle was not moving due to the speed of traffic. I took the vehicle back to the dealership and complained about this problem. However, the service department failed to find any problem. The second time it happened I was driving on a straight road and the vehicle slowed down and completely shut off. Nothing appeared on the monitor nor the dashboard, just like the first time. I could not get the vehicle to start for 30 minutes. I even captured this incident on video that no matter how many times I've pressed the start button, I could not get the vehicle to power up again (engine or battery mode). Just like last time, I took my vehicle to the dealership, but the service department once again failed to find any problem with the vehicle. At all times, I've done my due diligence to ensure that the battery was fully charged before I begin driving for the day and with adequate fuel for the engine mode. Toyota's negligence and the poor quality of the vehicle have caused me an almost life-threatening accident.
