2001 Suburban purchase
 

Hello,

I'm a new owner of a 2001 Suburban with the 5.3L. I have done a little research about this vehicle but wanted to try to get some more input. I was wondering about all known serious issues with this vehicle. Something I can keep an eye on. Is there any upgrade kits for the transmission for better reliability? I also heard something about the wheel sensors need to be cleaned to prevent the ABS to coming on randomly. Any kind of summary of the issues? Any other input like this would be greatly appreciated.

Thanks,
Tom
