GN2018

Just looked up my records. I've never gone over 5000 miles between oil changes. At 46K miles, I have 10 oil changes. I hope that will help. I also installed the disabler last year. I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working. For some reason, GM did not include the number of cylinders running in the information screen like I had on other models. In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen. I can't find that on my '21 Denali.

From what I’ve read, yes, that would be the best thing to do. However, it is very expensive and there’s no guarantee that the lifters will actually fail, especially if you’re not going to keep the truck for its entire useful life. My plan is to wait until I hear a lifter go bad and hope I can catch it without it being a catastrophic failure. At that point, they have to open up the engine anyway so that’s when I’d mechanically eliminate the AFM. Plus, there is a 5 year 60K mile warranty on the drive train. I have an extended warranty so I’m good until March of 2027, so I’m certainly not doing anything mechanical before then. I do have the Range disabler and I change the oil way sooner than suggested hoping that will get me into the 100K mile mark at which point, I may sell the truck. I don’t drive much. My ‘21 has 48K miles on it so to get to 100K miles will probably take another 5 years. Probably more because I drive less now than the first few years of ownership.

Does lowering the truck change its towing capacity? I wouldn't mind lowering mine, but I loan it out a few times during the summer for my daughter to pull her travel trailer (5,000lbs).

Actually, it probably was the brakes. It's weird the way the messages came across, but I took it to the dealer thinking that something was wrong with the sensor and in fact, the rear brakes were shot. What I don't understand is why the messages never said, your brake pads are low. First I got the message I posted above, taking about new pads being detected. Then I got a message saying that the system needed repaired. It never said, change your brake pads.

You are correct - I was mistaken. I'll have to see on my neighbors truck. You're probably right, but it does look rather short.

Special order? I go on the Chevy web site and the only option I see for a regular cab is a standard bed.

Life would be a lot simpler if these auto companies would just make vehicles that people want to buy. I still can’t believe that they don’t sell a standard cab with a short bed. My neighbor has on that’s not too old (a RAM) and it looks great. Hope you’re happy with the new truck. Personally, I’d find it hard to compromise as much as you had to do to get what you want.

I've owned my truck for Just over five years. I put new tires on it (earlier than needed), I've changed the oil and filters ahead of schedule and now I just completed the fluid changes recommended using the severe maintenance schedule in the manual. It always hurts to spend $2,100 but I'm doing everything I can to keep this truck in good repair. For one, that's just my nature. Second, is that I loan it to my daughter to pull a small camper when her family (grandkids) go camping. Given the cost of a new truck, or any vehicle for that matter, $2,100 is a small price to pay for reliable transportation that also provides good utility from time to time. All tolled, I've spent $4,500 on maintenance - so less than a $100 per month and less than 10 cents per mile. That seems reasonable. I wish I had the tools and ability to do things like the brakes, but those days are gone. I did all the work on my cars in my teens through my 30's. Then I got a job with a car stipend, leased cars, and never had to even think about repairs. However, in retirement (8 years), I now own my vehicles and I'll have to pay to get things done. I think the best thing I could do now is find a good independent mechanic so I don't have to rely on the dealer.

Thanks for the input with actual numbers. I didn't do too bad because I had the Costco discount of 15% so it ended up costing me closer to $1,400. I also talked him down just a little so ended up spending $2,100 (including taxes) for the brakes, brake fluid change, fluid change for the transaxle and the front differential. I already had the transmission done so I'm up to date on my 45K miles / 5 year services using the severe schedule in the owners manual.

My '21 Denali needs brakes. It's at the dealer because I thought the brake indicator sensor was bad and it's under warranty. I'll go look in the morning, but they said it's just the brakes and quoted $926 for the front and $786 for the rear (rotors and pads). For a total of $1700. With a discount from Costco I'll get that closer to $1450. I'm sure that's expensive but of course, nothing is cheap and there's no way I'm doing it myself. So I'm asking how outrageous that price is? I'm not going to bother going and getting the truck and finding a good mechanic (I don't currently have one because I've been driving new so long) for a couple hundred but much more than that and I'll have to consider it. What's a good price for a complete brake job? Also, they quoted $210 for a brake system flush, which according to the manual (severe service) should be done every 5 years. So, I guess that should be done too. Looking for some advice. TIA

A few weeks ago, I tried to return my module for a refund and they put me in touch with Holly (who actually makes the unit) and they didn't agree with what I was told by Range. They didn't know any reason why it shouldn't work with the remote start. Accordingly, instead of refunding my money, they sent me a new on and asked me to send the old one back. All paid for by them. I did that and have had the new unit for almost two weeks now and from what I can tell, it seems to be working just fine. I've been starting my truck with the remote even though it's not too cold any more and I have not had the stop/start kick in. I'm not sure what happened to with the other unit, but this new one seems to be working, which I'm very happy to report.

My 2018 Silverado seats were much more comfortable than my 2021 GMC Denali’s. Sad.

I started the process to return my disabler today. On top of the remote start issue, I started getting an errant message about my breaks that does not happen when the module isn't plugged in. I've not had anyone touching my brakes and they are still the original brakes. I don't want to deal with this from a $200+ product especially attached to a $30K vehicle. I'm going to look into other options, probably a tuner. Or, I may just wait and if I get any lifter issues, do a hard delete of the afm/dfm system.

Yes, that works. The concern I have is whether or not I really want to do that every time I use remote start throughout the winter. Additionally, I've started getting an unusual message when I start my truck (with the module in). It says it noticed the brake sensor was engaged and asks if I want to reset the brake pad monitor. I'm pretty cost to returning this.

Interesting. I’ve never experienced that feeling.
