My cars suspension (driver side shock) has been making creaking, grinding, and/or knocking noise when traversing over mild bumps or road defects at slow speeds. The sound can be replicate by bouncing the car up and down. I am concerned my suspension components will fail under prematurely or under extreme stress. Noted, I brought my car to Toyota for inspection on 2/11/22 and they were not able to replicate the sound. Subsequently I found this related TSB: https://static.nhtsa.gov/odi/tsbs/2020/MC-10181779-9999.pdf. Additionally noted, I have a TRD pro model with a similar setup as far as suspension. I believe the known defect in the 2019-2020 TRD pros (4Runners) applies here. Lastly, there is such a small population or TRD Pro Sequoias (only manufactured for 3 years 2020-2022) I’m concerned it’s not enough to create demand for a TSB.

While I was driving on the freeway, my family and I heard a loud bang. I pulled over to check and discovered that our sunroof had exploded. We went to a Toyota dealership to have it examined, but the staff claimed it was caused by a rock. We opened the sunshade to check, but no rock was found inside. It was clearly an issue with the sunroof itself. Despite this, we received no help and were simply dismissed.

The gas tank on my vehicle started leaking. It has a crack in the tank. I have not been in an accident nor have I hit anything to cause damage to my vehicle. The vehicle had been parked for approximately 6 hours in my work parking lot when I was notified that the tank was leaking.
