They both are still fine i beleive but i had a code long time ago that said service powersteering so i just got my letter other day and they told me to take it in today think they will fix it all?

 

The letter for the cat was only to notify you that if you have issues they will replace it. I believe the new cat warrenty is 10 years 100,000 miles. Are you having problems with your cat? Does your car feel sluggish? Are you seeing high boost levels? If there is no issue with your cat they will not replace it.
