I just purchased a 2017 Silverado with 43,000 miles and I am now noticing a small rattling/clicking/knocking noise coming from underneath the divers side area when I gas it or accelerate. Is that normal? I’m just curious because I would at least think it being a 2017 these transmission/engines should be quiet... anyone else having the same issue? Didn’t want to ask the dealership to look at it incase it is normal.

Thinking it is your seat, lots of posts on here about the crappy seats in the K2"s.

Haha if the seats are some how connected to the gas pedal then I’ll believe that. Lol.

Grab the bottom of your seat in the front left hand corner, push up and down, and side to side. If the click is your seat you will probably here it on the up and down push.

Hey, how did your visit to the dealer go on Monday? New shocks?

From my experience from my 2002 Silverado, this is most likely a transmission issue. But let’s say you are right, accelerating can cause this loose seat to rattle?

Tomorrow was their next available date. My appointment is at 7am so it will give them all day to figure out what’s wrong with it. Will let you know once I hear back from them tomorrow.

Yes sir, my 14 felt like the seat was not attached to the floor. Made more noises than the seat in my 1973 Vega.

If this is a marbles in a can sound, with low RPM and the engine under a slight load, it’s more than likely the steering shaft seal letting DI pump noise into the cabin.

low speed pre-ignition. Mine did it until I switched from 91 to 94 octane. 

 

They all do it to varying degree's of severity. Most people think their hearing the injectors or fuel pump. You can tell its lspi when the ticking is inconsistent at part throttle under slight load, hill etc.

Just checked the truck today. Not the seats. Any other ideas on what it can be?

Have not had experienced this one, maybe this from above:

If the sound disappears when you turn the steering, like going around a corner, and then reappears on the straight, its likely the steering shaft boot. There is a TSB for the 2017s for this. I really don’t think it’s a predetonation noise or seat noise, if it sounds like it’s coming from under the steering wheel.

 

An alternative solution is to pump some lithium grease into the seal yourself to see if the noise settles down. If it does, that’s your issue.

Can a 2017 Silverado flex fuel take 94 octane?

      Transmission Woes :-(

      By No1UKnow · Posted

      Hello All!   My 2019 Colorado 3.6 LT, 4WD Crew Cab has approximately 77,500 miles and I recently began experiencing the well-known transmission shudder between about 30 and 65 mph. The problem had worsened to the point that I could no longer attribute it to road conditions - and I had decided to bring the truck to the dealer - when recently, I experienced a sudden loss of power while driving at maybe 40 MPH. Several warning lights flashed, the “Check Stabilitrack” message appeared, and the Check Engine, Stabilitrack, and Traction Control icons remained illuminated. The truck regained driving power, but it stayed in a low gear with unusually high RPMs for the speed. (limp mode?) Because I was only about two miles from home, driving slowly, I was able to make it back and run an OBD-II scan, which showed fault codes U0101, P0700, and U0100. My next trip in the truck was to drive it to the dealer the following day. That trip began normally, but after about a mile I experienced another loss of power, along with the same warning lights and the same “Check Stabilitrack” message. As before the truck remained driveable, but again operated at an abnormally high RPM-to-speed ratio and seemed stuck in a single gear. About a mile later, the dashboard lit up once more, this time displaying “Check 4WD.” Soon after that, I arrived at the dealer. I have verified that the truck still has its original factory transmission fluid, which means it has never received the corrective fluid exchange outlined in GM Technical Service Bulletin #18-NA-355.  That was Thursday of last week and I've heard nothing yet from the dealer.    According to Technical Service Bulletin #18-NA-355 and the build date of my truck, my truck should have the newer LV fluid. I've done a little research and read something about a problem with the wiring harness as well.   Anyone have an insights into this situation?  Thank you!!

      Gas Prices

      By PhilB · Posted

      Did you even read this article?   Even the title of the article says "U.S.-Iran Deal Doesn’t Mean a Swift Return of Oil and Gas Flows"   Remember, crude oil prices are based on FUTURE purchases by the oil companies.  Gas prices are based on FUTURE purchases by the station.  This article stated that many of the oil producing nations have to restart their processes to get the oil produced.  Then the oil has to be shipped to wherever.  And it doesn't get there overnight.  And most of that oil is not coming here. Check out this site:  https://afdc.energy.gov/data/10621   A graph will pop up to show where the US imports their oil from.  Notice that there isn't a lot of import from OPEC and Iraq.  Most of the US import comes from Canada. The US oil produces are selling their oil on the open market, which is why the US fuel costs went up.  So you're correct, the US oil companies are going to slow walk the price downward.
