Good morning,
I just purchased a used 2009 Corolla last week, and for the most part, I am very happy with the car. Yesterday, I did my first highway driving with it. I immediately noticed that when I got to 65 mph or higher, I could feel a very uncomfortable vibration. It doesn't feel like something is wobbling, but more like everything I can feel from the road is amplified. Even on brand new pavement, the ride is rough. At lower speeds, this goes away.
In researching this issue, I have found a few causes:
• High tire pressure: I haven't had a chance yet to check this, but will in the morning with my gauge when the tires are cold.
• Wheel(s) out of balance: A lot of what I am reading online points back to this.
• Tires out of round: A possibility, I suppose. The car has almost 13,000 miles on it, and I assume these are the original tires.
Do others agree that these are the most likely scenarios? In any event, I plan on stopping at the dealer tomorrow to press them on this. Is something like this covered under warranty, or will I be paying for any necessary adjustments or repairs?
Thanks,
Ken
