One or both front brake rotors warped.(overheated) take off and have both re-surfaced ("turned") or if beyond 'trueing-up' then replace them both. About 25.00 ea. (new)
At moderate speeds, yes. For higher speeds or tight cornering, you might be causing a problem.
Tires/wheels out of balance?
Alignment
Most likely its your tires. Could just need balanced. Or you might have uneven wear making it shimmy.
Probably worn steering and/or suspension parts. Have the front end safety inspected.
The most common descriptors used for wind speed are calm, light, moderate, strong, and severe. These terms are typically associated with specific ranges of wind speeds, such as calm for speeds below 1 knot, light for speeds between 1-10 knots, moderate for speeds between 11-20 knots, strong for speeds between 21-31 knots, and severe for speeds above 32 knots.
Only at low speeds, or worst at low speeds? Either way it's probably a bad front tire. Failing that, bad front wheel rim or front wheel rim not properly secured to the hub.
Wheel shimmy refers to a vibration or oscillation felt through the steering wheel, often caused by an imbalance in the wheels or misalignment of the vehicle's suspension components. This phenomenon typically occurs at certain speeds and can be a result of issues like worn tires, improper wheel balancing, or damaged suspension parts. If left unaddressed, wheel shimmy can affect vehicle handling and safety, making it important to diagnose and rectify the underlying cause.
You have warped rotors. They will need to be removed and trued or replaced. Causes of this are lug nuts overtightened, or heat from heavy braking at high speeds.
The blower motor speed resister is burned out.
I was considering a Lexus RX400h when I realized that it was very inefficient at freeway speeds 65-75 mph. Most of my driving is freeway at high speeds. How does the Toyota Highlander hybrid technology work? Is it still beneficial/cost effective at freeway speeds?
Because your motor is spinning faster at higher speeds causing higher rpm's
