Car Details: 2004 Olds Alero GL, 250K miles, well maintained.
Our car recently started shuddering/vibrating at speeds over 45mph. Once the shudder begins, it continues for the remainder of the drive. It doesn’t feel like it’s in the wheels or the steering column, and there are no warning lights on the dash. It seems to be more intense when braking, as if something were fighting the inertia of the vehicle. There’s no difference in the sensation when driving around corners.
After a few minutes of driving, there seems to be a burning rubber smell that is concentrated near the windshield in front of the driver’s seat. I have no idea if this is related, but I suspect that something is damaging a hose with heat or friction. I’ll be taking it in to a mechanic, but I’d like to have an idea of some of the possibilities before going in.
Thanks for your time.
