miles why? vibration frt rt @ hi speed Frt right vibration only at high speeds (stops with sudden braking). Had master cylinder replaced at 70,000 miles after brake light was on all time. VSC/ABS/TRAK lights now come on after about 10 minutes of city driving. No one can explain vibration (of course it is not a "reliable" vibration) or V/A/T lights being on....Anyone with similar issues and hopefully resolution?

When you say,"no one can explain the vibration" , I hope it is not a professional mechanic. Take your car to a shop and get it checked. Symptoms you describe could be dangerous to yourself and others on the road. .
