Ticking noise coming from engine

[John Bendzsuk]

Guys I need some advice. I have a 2015 Yukon and when I sart the engine I hear a ticking noise. It is really loud under the drivers side wheel. It doesn't stop either when the car gets going. I hear it if I'm stopped and the windows down. I took to Chevy dealer and the lead mechanic told me that's normal because of the new motor and pistons they use. It is really freaking annoying. I want to take to another dealer since it is under warranty still. Let me know if they do make this noise or what you guys think the problem is. Thanks for any advice.

Not normal. Take it to another Dealer and you could call GM customer service and open a case. Maybe there is a TSB on the problem.

I have same exact sound from same location like you described. I just got 2015 Chevy Tahoe LT. I schedule apoitment for next week i hope nothing serious. Also i noticed slight engine vibration wnen car standing and very big vibration when driving on the highway between 70-80 mpr.

There are lots of threads about this, search around a bit. In most cases the noise is normal with the new setup, but some have had it worse (and it's been other things) and it's been addressed.

Good luck.

I bought my 2015 Tahoe LT a year and a half ago with 20k miles and had/have the exact same issue. I took it to the dealer and they said it was normal with the new engines. I respectfully complained and expressed my displeasure but nothing came from it. It sounds bad but I guess it is the new normal. This is my 5th Tahoe and while all the other improvements are awesome, it is disappointing to have a ticking noise coming from the motor, especially considering how expensive these trucks have become.

Not sure if this has been fixed on the newer models, but the older 6.0 and 6.2 motors had a tendency to sheer one or more bolt heads on the exhaust manifold. My '09 Denali has 3 sheered exhaust manifold bolt heads as we speak and will 'tick' until the manifolds are good and warm.

i have a 2016 yukon denali that had a ticking noise coming from the same area (sounded like front left side engine compartment/ maybe behind dash) anyways, took it in to dealer, the tech said he used "ears" to isolate where it was coming from. it was the magnetic ride shocks, and there was a service bulletin for that problem. they replaced front shocks and no more ticking!

I have a very loud ticking/tapping sound that I can hear. I can really hear it if i put a pry bar to my ear near the oil pan. I know what injectors sound like. I took it to one dealer, and they told me they could not fix anything if they did not know what the problem was.... WTF???

I just purchased a 2017 Yukon XL Denali and put 2000 miles on it in the past 4 days. I hear a slight ticking coming from the same area. Will take it in to have it looked at.

Any updates on this? Thanks.

Eric, Welcome, MRC shocks are on the Denali trim line.

Short answer: Lifter and Maybe Camshaft. Long story below.

I have a 2017 Yukon Denali (44k miles) and I was faced with the same exact issue about 2 weeks ago. I read a few places that I could maybe solve the issue with a additive that could assist with maybe dirty oil. I tried that and there was no change. About 30 miles it sounded like it was getting worst. Sunday afternoon, I was at the mall and something told me that I need to go to the dealer ASAP. My normal dealer didn't have any available appointments for 2 weeks. Our 3rd nearest dealer had something avail on the next day. I drove straight from the mall to dealer. When got off at the exit, the motor was knocking so bad, check engine and traction light came on. Im so glad I went at that time. The dealer called me 2 days later and said it was the lifters. Then the dealer called me the next day and said the camshaft was damaged as well. Said they had to order the camshaft. Said it would be a few days. I'm not even close to being a mechanic but I know this is a major repair so we'll see how long it really takes.. Its been a week so far. Its covered under warranty. The gave me the smallest Buick crossover that they could find (Envision) for a loaner which I'm pissed about.

That Denali has had a rough life. Its in not so pretty shape.

Just picked up a 2015 Yukon and it is making this tickin noise. Repetitive and rhythmic. Does it from cold to warm. Cant hear it inside the cab. Ive read the threads here that say its normal.

Question: if it is a stuck lifter, will it throw a code/check engine light?

yes you'll get a code ,i think allot of times people hear the high pressure fuel pump and think it a lifter...also the electric fans will "tick" as well sometimes ...basically these engines sound like crap when they idle

gotcha. Thanks man. Here I am reading this forum with my face in my hands as I walked away from a perfectly good 06 Z71 Tahoe with 180k miles.
