2003 Toyota Highlander Q&A

2003 Toyota Highlander Question: When driving approximately over 50m/h, inside my car is so loud.

(1)When driving approximately over 50m/h, inside my car is so loud. It is hard to hear each other. I started the car and checked engine and everything seems fine. Any idea? (2) Also my check engine light is on. It came on, I changed the fuel cap, reset it but came on again. I went to a mechanic, he left the hood, and there was a loose hose, he plugged the hose back, cleared the check engine light with his computer. After a month, the light came on again. Please help thanks -

Just came back from Toyota dealer. The engine light was something minor and had to do with a lose hose. The noise was rear bearing. Costed me a total of $650. Thank you -
