Just bought a 2018 Denali with 42K mi

[billyinslo]

Just joined this group (Thank you for the warm welcome) As the title says, I just purchased a 2018 Denali for the wife. She loved the color, Mineral Metallic (433B) Haha, we all have different criteria, for me it was the 6.2 w/10 spd. and the towing specs. Carfax shows good service history all done by local dealer where purchased. I will be towing a 27 ft Travel Trailer a couple of times a year, otherwise it will just get normal use by my wife with a couple thousand miles/year.
The GMC dealer I bought it from offers a 3 year factory warranty for 3100.00 and change. My question is, should I purchase the coverage? I will do all regular maintainence myself but the finance guy at the dealership says even if one electronic gizmo goes out
I could spend a grand for repair/replace. Seems like cheap insurance to me. What say you guys? TIA

Beautiful truck!

I've never purchased that kind of insurance, so I cannot help you there. Other folks will chime in though with their views, as this topic has been discussed here before. Search here a bit on 'factory warranty'

 

[billyinslo]

Thank you, I will do that. This is a very robust and well built forum BTW. I like that "previous or similar thread (?)" feature, kind of a "look here dummy before you post something that's been beat to death already", which I am often guilty of.

There are two camps on this. A lot of folks here, swear by them if they’re from a reputable company. Any problems with the cylinder deactivation on your engine, could easily eat up that initial cost.

On the other hand, there are folks like me who just prefer to be our own insurance, confident that we can deal with whatever comes up, at minimal parts cost. So far, that strategy has worked very well for me and saved me a bundle.

For the warranty depends on your skill set. If you have a good scanner and are comfortable replacing modules and stuff like power lift gates, seats, Mag ride shocks, then id skip. I have a 2015 LTZ I bought used in 2019? That I had to make a good amount of repairs on that I did DIY. If I paid for a shop it would have been more than the warranty cost for sure. Although this truck was bought with 90k on the clock and now has 160k as its used heavily. Lots of short trips as well with 5 kids in it at times so it’s being “taxed” lol.

I’ve replaced to date:
4 fuel injectors and fuel rail
Plugs
Rear mag shocks
Air compressor
Stab control module
Side detection modules
Power lift actuators
Passenger window regulator
Rear seat recline motor
Wiring repair to harnesses
Had to pull intake manifold to clean intake valves and added catch can.

Now needs brakes (all new rotors and pads) and front mag shocks. Will do that this summer

$3100 seems pretty steep to me for the "what-if" insurance feel good. We bought our 2017 Denali with 41k on it in 2019 and they offered the almost the same exact sales pitch - but for $1700. Platinum coverage, no deductible, wheels and tires until 100k, etc.

We opted for it to make my wife feel better long term since it would be her DD and a road trip machine. I will say it paid for itself twice over what we paid for it. I'm usually not an extended warranty guy though.
1. 2 tires covered
2. Leaking trans lines covered
3. Front mag ride struts covered due to oil puddles on my garage floor
4. Seat vibrators on driver seat
5. Complete radio/HVAC module replacement

it's a gamble just like gambling, 50/50 chance it will pay off, the benefit being it could pay off quite well in the event of a engine failure, transmission failure, etc
for that low of miles $3100 is a bit high I would try to negotiate that price down, the sales person is getting a cut of it, you can squeeze them a bit.
keep in mind the factory warranty is expired due to age.
just don't take a low tier warranty those are useless, take the high or mid tier or nothing.
high tier generally covers bumper to bumper, mid is generally powertrain only, low tier is garbage and covers basically nothing and gives them a "out" to decline coverage due to legal fine print. .

In any case READ it so you have a understanding of what is and what it NOT covered. little things like seals and gaskets make all the difference

Key words here, READ. Gambling is hardly ever 50/50. House usually has the odds and with the extended warranty the carveouts are what give them the favor. I am curious of more details on the warranty they offer. What does the mileage top out at, 100k? What electronics are covered? What aftermarket mods will null your coverage? If they offer a high mileage powertrain warranty beyond 100k miles, that is what I would want. Not too concerned about electronics but that is just me.

I take it you have never bought a warranty on a vehicle? unless it is a very good warranty provider then most electronics are not covered unless explicitly stated in the coverage and even then it can be limited to very specific things. aftermarket mods are not covered in pretty much ANY case, but what they don't know wont hurt them and unless it was a obvious bolt on mod there never going to know, most warranty's are no more than 60k (starting at existing mileage and excluding any factory warranty remaining) unless it is a gm cpo warranty in which case they can or may do a 100k powertrain.
so for instance if it was a 2022 and at 40k, then (for example) a warranty would be 60k miles covering you up to 100k, excluding the first 20k or to 2027 which would still be factory warranty to 60k or 45k whichever the case and whichever comes first.
in that case they are off the hook at the beginning it would only kick in after the factory warranty has expired.
in some cases you can come out better in the long run buying a gently used CPO with a better than new warranty.

I have bought extended warranties but not for a GM vehicle. My reference in regards to the aftermarket was not that the aftermarket product would be covered but would it affect the warranty validity. Several providers offer electronics coverage you just have to buy the more expensive plan.

I recently bought a '19 Yukon Denali with 65k miles. When I considered all the features and complications of this loaded vehicle, and that my use case was Trailer towing, I opted for an extended warranty for about $4,000 that will take me through 125k miles.

At the time, I did not know about all the 6.2L issues. Mine is NOT in the big recall, but being the same engine I feel a bit calmer having the insurance.

I'm still not clear on why mine is not in the recall. I absolutely love this vehicle and I'm hoping for 3 years of wonderful driving!

 

[billyinslo]

Thx all. I'm very skeptical of any add-on warranty. It's like insurance, I hate insurance, but I got cancer when I turned 65 and thankfully, everything was covered 100% by Medicare. One year earlier, and I would be screwed!
I am mostly concerned with the AFM/DFM issue. I have searched, and read, until my eyes crossed. I'm looking for the definitive answer as to whether my 6.2 has the earlier AFM or the improved DFM. Is there a production date or VIN range published somewhere that would tellk me? I read that 2018 was the year it changed, which is why I bought the low mileage 2018. Also, what are the production numbers of 2018 6.2 vs the number of failures reported?
I will try again to find those answers and share them if/when I do.

the L86 has AFM, the L87 with DFM wouldn't be in a 2018 (K2). It could be a T2 2019 silverado and is what they use in 2021+ T2's SUV's
generally the Silverado's have been given the updated designs a year earlier than the SUV's. But GM also makes what is called a LD (last design) with the pickups so there are some 2019LD silverados out there
2014 silverado's got the k2 update a year earlier than the SUV's
2007 silverado's were made with either the gmt800 or gmt900 platform
2000 yukons were made in either OBS or GMT800 platform, same with some escalades I think, unsure on tahoe suburban.
generally it is a good idea to stay away from a new model year (2018 is not a new model) because for one they can have design bugs and then gm will tend to make various changes over a short period of time making it hard to get parts for a particular year.
the K2 design alone 2015-2020 suv's saw changes in the transmission of 6sp, 8sp, 10sp some changes were mid year it can be all screwy same with rear axle ratio a lot of them got 3.08 a few got 3.42 depending on the tow rating or engine. a few unicorns got the 6.2 that were not denali or escalade, same with the pickups
some have a regular key, some are push to start, some have a regular shifter, some have push buttons, some have regular cruise, some have adaptive cruise, some have both regular or adaptive (switchable), some have automatic high beams, some do not, some have HUD some do not. the list goes on....
If you are shopping online for a K2 and you want specific features it can be a nightmare because most dealers or sellers DO NOT list specific features or they are listed incorrectly or they don't even know..... so then you have to hope the pictures show it.

Haha, now it's clear as mud. Thx for all the info. It is a very well cared for (CarFax), low mile (42K), Denali with just about all the bells and whistles. It has two working key fobs so now I am studying the manual and trying to learn and understand all the friggin settings. They have more acronyms than the US Government. The sound of that 6.2L V8 is downright intoxicating! The only time I get to drive it is when I tell my wife I'm going to go wash it and fill it up for her. It's ok though, I have a 4.4L Aluminum V8 in my 2002 BMW 540 Wagon which sounds different but just as good.
I have a good feeling I will find the answers to all my questions here on this forum, so thx in advance.
Billy

Get the longest possible. 5 year 100k or longer.
