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.
Unfortunately, the shop is probably putting cheap aftermarket cats on. We regularly see aftermarket cats lasting about a year. The real fix to this would be to get a genuine honda part. They are typically so expensive that companies like geico will not cover replacement of factory parts, and will opt for brands like walker and magnaflow. They are all junk.
