Have had 2 of the 4 O2 sensors replaced.
Brakes replaced twice.
Water pump replaced.
Worn seats.
Driver side door stuck closed and now fixed, but won't stay open without holding it open.
Numerous (4) oil leaks that had to be fixed.
If you own one of these cars the best thing to do is drive to the newest cliff and drop it off the side.
When the car is running it's so comfortable and rides so smooth, but when it's broken and has to be fixed it always costs and arm and a leg. It's in the shop right now and is going to cost me $1500 to get it back in running condition.
The Catera is not a real caddy!
Its just a european imported Vauxhall Omega badged as a Caddy. I would say don't buy a fake Cadillac buy a real caddy.
