I’ve had a Suburban and 3 Tahoes. Loved them aall and had very few problems with any of them and no serious or expensive problems. The most expensive repairs were replacing the A/C compressor and the front differential chunk on my 2005 Z-71. Remember the admonition about not driving in 4wd on hard surfaces roads, that it can damage your vehicle? It’s very true! I forgot to take mine out of 4Hi. When I realized it 35 miles later, it was too late. Would I buy another one? Absolutely! Mine have all been great vehicles and are especially great highway vehicles. My 3 Tahoe’s were all 4wd and I never had a problem with any of them except as mentioned above and that was my fault.
