Good morning!

 

I hate to be the guy that reopens an old thread on their 1st post...buuuut..

 

I just picked up a 2014 LTZ Z71 with 46000 miles on for what i thought was a pretty damn good deal, I was super picky about the test drive and didnt find anything about this truck i found alarming in any way, the thing is immaculate inside and out. LSS.

 

Got the truck home, it sat for a day before I started it, and holy crap! What the hell is that ticking sound? How the heck did I miss that on the test drive/walk around is beyond me.

Took it back to the GM dealer and they said, its normal. Well, holy god is that annoying, if i was able to hear that inside the cabin i'd be super pissed having to listen to it.

Has anyone discovered a cure for this yet, or is it truly "new technology"(the weak acceleration is a whole different subject) and I'll have to adjust and deal with it.

 

Thanks again!

I bought a 2015 Chevrolet Silverado 1500 Z71 Crew Cab 4X4 with the 5.3 engine. I've had it a week and have noticed a ticking noise that sounds like it is coming from underneath the truck at the bottom

They are a bit noisy. Normal noises include:     On the not so normal noises, we did have to replace the vacuum pump on a 2014. Truck sounded like it had a lifter tick. You could hear it from t

I have heard small exhaust leaks present themselves as a tick sounding noise. Since you are mentioning it coming from the bottom, might be something to investigate.

If you’re not used to DI engine noise it may sound horrible. The injectors are noisy and seem to get even more noisy over time. Especially irritating when using a drive through service like fast food or the bank. As for the acceleration issue, it could be related to what many attribute to the gas pedal sloppiness. There is a thread on that here somewhere. Just Google GM truck gas pedal fix and it should bring you to the thread...it’s not letting me copy and paste for some reason.

Yessir, i've stumbled on to the partial fix some folks are talking about with shimming the pedal or replacing it with a different PN. Thanks for the input. I find the noise to be irritating outside the truck, thankfully I dont hear it inside, its dead quiet in the cab, the wife loves how it sails down the road. Guess its something i'll just have to get used to. Thanks again.

2017, 1500 Silverado LT 5.3 liter engine

33,000 miles  quiet as a mouse until 2 weeks ago. Then LOUD tapping started on drivers side in the wheel well also under the hood.  Truck has been dealer serviced since day one.  Regardless of what anyone says here. I believe it is NOT normal.  
So called Normal sounds like an easy way out for GM.  No modern motor has Tapping, Ticking, and or Knocking. 
I WANT MY TRUCK FIXED !!!

If it’s that loud and it’s on the driver's side it’s most likely the brake vacuum pump. There’s a recall on it...take it in and get it replaced. 
 

Other than that, hate to break it to you...virtually every modern engine now is “loud”. The days of those Lexus commercials where you didn’t even know if the engine was running, are LONG GONE. 
 

They now wrap these engines in foam insulation’s to try to combat the direct injection noise. All of them have to do it. Open a hood, it’s there...the noise, the insulations. In terms of noise, the silverados I’d say are about normal/average on the spectrum...there are others much worse.
