Had to replace the engine at 90,000 miles, seemingly due to poor lubrication during the V4 / V8 operation. Have had to replace full struts and shocks twice. Taillights have failed and its about $1000 each to replace, cant just change a bulb - have to replace the "module" Multiple other expensive mechanical and electrical failures. Transmission shifts roughly.

I bought this 2017 Tahoe w LT trim new. Have 60K on it now and have had no issues with it. We are not towing with it or doing high speed racing so we find the 5.3L Motor is smooth and quiet (and have not had any lifter issues which others have reported). Transmission and suspension also smooth. We keep Michelins on all our vehicles and have found this Tahoe very quiet and comfortable for road trips with 4-6 people and luggage. The LT trim pkg deleted some comfort items I wish I had (like heated steering wheel) but it still is pretty much leather-and-loaded so it was a good value at the time. I have had Suburbans for 35yrs before purchasing this Tahoe and I will probably go back to a Suburban for the extra cargo space when I trade this Tahoe in. But this has been a nice and reliable vehicle for us. No complaints.

The GMC 2017 Yukon Xl Denali that I own has costed me over $5,000 in just under two years. There has been a total of 5 strut failures that I have had to replace out of my own pocket. General Motors refuses to help in any way. I purchased this as a GMC certified vehicle and spent over $50,000. I have not even owned this vehicle for two years! Stay away from all General Motors products. They do not care about you they just care about your pocket book.
