I am sure there answers to this questions somewhere here but I am new to this forum. MY question is if one were to install an after market intake, will it void the limited warranty? Thanks in advance.

Magnusson Moss warranty act protects you. In short, dealer has to prove the aftermarket modification was the root cause of a failure you want warranty coverage in.

 

Example 1: you install CAI and all of a sudden your door locks no longer work and need to be replaced. Locks would be covered if you are still in your warranty period.

 

Example 2: you install CAI and go through a high pressure car wash that soaks the filter. You drive and engine goes dies. They look into issue and find water in your cylinders. You bet your butt they deny warranty coverage in your new engine.

 

Real life example: I have a catback, intake, and a tune on my 2014. My radiator was leaking due to excessive cycling of the t-stat. My radiator was replaced no questions asked under powertrain warranty.

 

All comes down to how big of d*cks a dealer want to be. My dealer is awesome but some dealers will kick back on moot stuff.

Highly unlikely they would void your warranty, but as @Waterfowler41 said there are some situations that could.  If your worried about it GM performance does sell a CAI

The reason why I asked is that I had recently bought the truck 2015 silverado from a nissan dealer, and now with less than 2 months the engine bogs and stalled whilel i was driving (on a sunny day). it won't start  anymore, turns but i can hear little rattles and no oil on the dip stick. I did however checked oil level during purchase and was good then. my truck is under 70k mi which should fall in the NEW LIMITED WARRANTY? but the truck came with the aftermarket K&N filter so I am iffy about dealer blaming it on aftermarket parts.

 

Has anyone ever had this issue or claim warranty before. I just want get some advice and how to go handle this headache. Thanks.

GM has a TSB about the use of K&N style wet air filters I can’t find it right now but it blames the oil you use on the filter of coating the mass air sensor causing various problems. Yes there are several people on here that have had problems with stealerships blaming aftermarket air filters/CAIs for their problems and denying claims.

 

Also so since you bought the truck used unfortunately you don’t know the prior history. GM has and does flag vehicles in there computer system usually highly modified ones or people who try to get warranty work at a dealer after being denied from a different one. Once flagged GM won’t pay one dime for repairs. I doubt your truck falls into this category but just something to be aware of. But the truck might be known in the system as being modded already.

 

The Maggy Moss act is great until you have to go to battle with a manufacturer they have teams of lawyers on the payroll you don’t who cares if you win against them if they drag it out for 3 or 4 years and you’ve spent tens of thousands on your lawyer and didn’t have a truck to drive that your still paying on...

I've run oiled filters on my last 3 cars no issues.  If you are concerned, use an MAF cleaner.

I don't know too much about these filters or oil filters but i think it does have  a MAF cleaner on the side of tube, connecting to the engine and filter.

That’s your MAF sensor, they make a spray cleaner to clean the thin filament on the sensor.

Steps to clean:
1. Remove MAF sensor
2. Spray MAF sensor with cleaner
3. Let dry overnight.
4. Reinstall.

All cars come with a mass airflow sensor (MAF sensor).  This sensor sits in between your air filter and your throttle body.  Its job is to measure air flow coming into the engine which the car's computer uses to control how much fuel the injectors are providing.   

 

Oil is used in some (most K&N) aftermarket filters as a binding agent to improve filtration.  There is a particular train of thought (from GM) that oil can travel from your air filter and collect on the tiny filament on you MAF causing fueling issues. This can be avoided by oiling your air filter per the instructions provided with the cleaning kit and occasional cleaning of your MAF sensor filament. 

 

Your description of the issue above sounds beyond anything an intake can cause. Did you check your coolant for signs of oil? If the oil isn't on the ground under you truck it had to go somewhere.  Is your tailpipe covered in build up like your burning oil?

No, i haven't checked the coolant.  the tailpipe does have some build up and at the end of the muffler there is an area of some black buildup around it.

Yeah I agree with you on this IMO a guy would have to basically soak the filter in oil and then stick it back in to get it to suck up the tube. But the dealer can and might blame it on that depending on what his problem is. Of course anybody that makes a wet filter is going to disagree with this saying as long as you follow the instructions. But we don’t know if the previous owner(s) did? I’ve ran plenty of K&Ns in the past on all kinds of GMs don’t anymore cause I live on gravel now.

 

Wish I could find that TSB. Anyway read page 2 of the link below 2. and 3. under correction 

#2 take photos so we can blame it on that (IMO)

#3 will tell them if there has ever been a tune in the truck

If it were my truck I’d get on Craigslist or hit up the local salvage yards and find a stock box, filter, and tube to stick on it and wipe out the intake before I drag it to the dealer if the CAI is the only mod. Then I would play dumber than dumb “I don’t know what’s been done before? I just bought it.”  

 

Other problem is the only factory warranty left is the powertrain 100k 5year which doesn’t IMO actually cover all the powertrain anyway so he might be SOL since there is no way of knowing if the oil problem is currently related to the no start problem. Homeboy at Nissan might not of put enuff quarts in it, the wrong oil filter on it, ect. but it was losing power and now won’t start because maybe it’s not getting fuel? Who knows till it’s diagnosed. Rattling might be the vacuum pump. Who knows? I would hope the oil light would have came on before it did internal damage or the check engine light if the mass air or another sensor is sh!t.

There werent any oil light warning. But when the truck bogs n power went down, the Check engine and traction control light came on.

Where is your truck now?  I'd have phoned the place of purchase once the problem occurred.   If you've already done this, what was their response?

I did called the dealer where i bought it from and told them the situation and they said its an engine problem which the 100k warranty should cover and for me to take it to local chevy dealer. They said let them know what the problem is and theyll help what they can. So its at a local dealer now getting checked.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      I can only guess as well that something was clicked on that brought you to the half ton choices by accident. By all means try again and chose the 3500 and sort out that its the cab and box configuration you want and choose four wheel drive ( rather obvious to have a transfer case ) and to make sure the dually isn't chosen. I find or at least did a couple of years ago when I was sifting through the options that it would sometimes jump ahead after choosing the series of truck and in this case 3500 and skip some of the other initial configuration choices and have to watch the heading bar and sometimes back up by choosing the first in the series of option break downs. I think sometimes the computer will remember items that were last chosen and skip over the first part. Anyway go through it all and depending on the trim level chosen and I think the LT is one that may fall into that where the option of having the 4 high auto transfer case can be chosen, where as a High Country doesn't show that option as it just comes with the fancier ( not necessarily better though in terms of potential problems ) transfer case but for sure both transfer case choices are equipped with high and low range in the HD truck segment. Like Newdude said who works at a dealership, its the half tons that are the ones that will come with the single speed unless certain options or trim levels are chosen that add the two speed transfer case but as your looking at an HD, you don't have to worry about that hot mess.    One item that at least didn't show up and not sure if it does yet or not in the HD options on the manufactures pubic website is the upfitter in cab switch option if one is desiring that. Unfortunately its not wired in at the factory but the panel with the switches is on the dash but the wiring harness to be installed gets tossed under the rear seat to be installed by whomever after the fact to complete the installation.

      Yesterday we brought home a 6yr  old Havanese dog from a nearby SPCA.  We've had her for 24 hours and we are delighted with how well she is adjusting to her new home.  It  was a huge decision to adopt a dog at this stage in our lives but we believe we made the right choice!   it was reported that her first 6 years were ones of neglect.  I think she's already realizing her life is going to get a whole lot better...  so is ours!

      Which 2027 engine will you choose?

      By Coastie05 · Posted

      No doubt, I definitely agree with you. However, considering the 6.2 and 3.0 have been catastrophically failing with very little miles, I figured I would put trouble free. I’m at 18,4xx and still not a single issue.

      It’s never dry here but it gets hot. My 4 vehicles I keep at home drive an 18 mile loop. One 6 days a week. Two about 3 days each and one once a month. Only one goes on trips about 4 times a year 1000 to 2000 miles each time. One 26 years old gets driven once a month for 22 years. One 14 years old goes 6 days a week. The other two are recent at 2 and 4 years. All are performing normal no extra service other than that would be half of recommended or severe service in the maintenance manual. No extra water or steam out the exhaust or premature plug wear. I would consider an 18 mile loop would be enough. So apparently once a month at 18 miles for 22 years has kept the collector car running well. About 45 minutes a month.
