I had a 2018 Sierra SLT and thought it was the best truck ever until I traded it for a new 2020 Sierra SLT X31. I went with my son to buy a new 2020 Silverado and while I was at the dealer they made me an offer I couldn't refuse on a 2020 Sierra. I have had it for 2 months and can't believe the improvements over the 2018 which was excellent truck. I love the 10 speed transmission, extremely quite and smooth ride , 5.3 V8 performance, fuel economy, extra room, rear seat hidden storage compartments, adaptive cruse control and especially the multi pro tailgate. The truck feels much more solid and 3 driving modes makes it fun to drive. I do miss the adjustable peddles, Cocoa Dune Leather option and overhead console storage for my glasses but very happy overall. I was unsure at first about getting rid on my 2018 but now I have no regrets and would defiantly buy it again. After 7 months I have found absolutely nothing wrong not even minor issues, great truck built like a watch! Update: I have now had the Sierra for 3 years and 43,000 miles and still the perfect truck, no problems and 18 mpg city 22 hwy average over 3 years.

Battery was dead on several occasions with nothing being left on. Then I was driving home and all of a sudden I heard a banging noise from the back driver side it started to lose power and it just died. I only had 8,200 miles on the 2020 at4. Had to have it towed to dealership on a Saturday and by Monday they still did not have an answer. Hoping to have an answer tomorrow. It died on the way to trade in basically. I heard a loud bang and had to pull over several times on the way to trade it in and the engine light came on. It was a lemon gm refused to replace telling me they would then sending me a refusal email saying it was normal wear and tear? Wtf. Will never buy another gmc again.

After 2 months of driving my new GMC Z31 Crew Cab Sierra SLE I am loving it! I upgraded from a Nissan Xterra. The increase in vehicle size takes some getting use to. The additional room in the cab is wonderful. Amazing how all new trucks are loaded with technology and get reviewed based on looks. The remote start automatically heats the steering wheel & cab, fantastic. Pacific Blue Boy is the colour and it can look black in certain lighting. The ten speed transmission shifts flawlessly. The aftermarket Alea leather after market seats are a nice fit for our messy children. The Z31 off road package has a higher clearance to the ground which works well for me at 6’1””. My first V-8 motor in a long time. I love the sound & power. Deep discounts, no interest, and no payments for six months were also very attractive. The back flip tonneau cover will keep the ski equipment safe! Pocket stay anchors help tie down my raft. Overall fantastic!
