Summary
The 2000 Chevrolet Tahoe, while generally reliable, has some common issues that prospective buyers should be aware of. Engine problems such as oil consumption and “piston slap” (particularly with the 5.3L) can range from minor annoyances to requiring significant repairs. The 4L60E transmission is prone to slipping and harsh shifting, potentially leading to costly rebuilds or replacements. Suspension and electrical issues, while less severe, can add to the overall maintenance burden. Rust is also a prevalent concern, especially in regions with harsh weather conditions. The potential cost to address these issues ranges from a few hundred to several thousand dollars, depending on the severity and complexity of the repair.
