2026 DENALI 6.2L

[PUSSLEGUT]

I have 3 more mortgage payments on my house. I am planning on purchasing a new GMC 6.2L Denali. Is it safe to purchase a new truck? I have been reading alot about engine failures. Has this been corrected. What should one do?

There are plenty being sold. I had a 6.2l 2023 that I sold prior to the actual recall. I would have kept it had the recall come out before I bought the 3.0l 2025. I'm ordering a 2027 Yukon next month with another 3.0l diesel. I'm thrilled with the fuel economy of the diesel. 

 

Go to your local dealer service department and talk to the service manager and get his take. If I was sold on a gasser, I'd lean towards the 6 2l rather than being a first year owner of the 6.6l.

I agree with Tim.  As tech heavy as engines are these days, no way I’d be an early buyer of the new 6.6.  Of course, I bought my ‘26 Denali w/the 6.2 after dumping my Tundra with it’s defective 3.5 liter imploding engine disaster, so I’m a little gun-shy.  That said, my 6.2 has been rock solid.  I don’t drive it like I do my BMW Z4 M40i, but I don’t baby it either.  I got a V8 for a reason.  But I’m averaging 18 around town and 22 highway.  I have seen 24 highway as well when I wasn’t loaded up heavy.  Considering my Tundra with the twin turbo V6 only got 14.5 in town and 17 on the road, I’ll take the 6.2 all day, every day.  If I were you, I’d grab a ‘26 while you can.  Inventories are probably gonna start dropping and I’ll bet the deals will start looking sweeter as well.

Just buy and extended warranty and don’t worry about anything else.
