You'll Like This Car If...
All-new design w/more interior room. Adult-friendly 3rd-row seat. Independent rear suspension. Powerful engine lineup. Most advanced Yukon to date.
You May Not Like This Car If...
Massive size means parking can be tricky. Awkward push-button gear selector. City fuel economy still ain’t great.
