Worst vehicle I've ever owned
June 11, 2018
One would think GMC would know how to make a quality, reliable vehicle. One would be wrong. I've owned my 07 Yukon XL Denali from 100,000 miles to the current 128,000. It has had over $10,000 in repairs PLUS now it needs a NEW ENGINE. It dies on long trips randomly then comes back an hours later (insanely common and GMC does NOT KNOW what causes it in thousands of their vehicles.) The oil pump went out, starter bad, water pump leaked, air shocks blew, steering rack failed, rear main leaks, all the interior door handles have chipping chrome that have made both my children bleed, the zone heating doesn't work, transmission shifts rough and clunks after 3 motor mounts replaced and dealer states "it is normal per GMC". I personally know 2 other people that have this engine who have the dying out problem as well without solution. Did I mention it has now spun a cam bearing and I need a new engine at under 130k? I expect problems over 100,000, but not this. Terrible.
