Nothing really except in 2003 we had to swap the block, because something happened I don't really remember.
And just recently I blew an oil pan gasket, but that comes with mileage.
And also the Lumina LS is notorious for having strange brakes...
This car has a lot of get up and go for a 13 year old Chevrolet. Was moms car, now it's mine, and I love this car!
I sincerely hope you have better luck with your Lumina than I did with mine. It decided to throw a rod after 61,000 miles. I guess the 4 years of meticulous maintenance it received from me just weren't enough.
