My 2003 honda crv had it’s cat stolen in 2022. I got it replaced and almost exactly a year later the new cat starts making rattling noises and the computer is running an emissions system code. I get the cat replaced at the same shop and now almost exactly a year later again my cat is rattling.

What could be disintegrating my cats? Is it because my car is burning oil? I’m sick of paying for a new one every year.

    The math says you are driving 1450 or so miles a month. That means you are using a quart every 2000 miles. Not good for the cat but not terrible oil consumption at all.

    I’d agree it is cheap cats causing the problem IF your check engine light is not glowing 100% of the time. In that case, I’d say there is an additional problem not identifiable unless you post the codes.
