I bought a 2011 Silverado in october of last year.. Since then i have had it in the dealer multiple times.. Whining from the alternator and a pop in the gas pedal when i first start the truck (hot or cold) then start to drive. The dealers have said they dont feel it or have never heard of it??????

I have both on my 2009. The pop does it when I first turn out of the driveway. It is very slight but you can feel it in the gas medal a little. The whine wasnt really noticeable untill I installed the OGM 1.

I got the whine when I installed the OGM-1 too. Drives me crazy. I've done everything other thenreplace the unit it self.

I have tried several things to fix it too. I think the unit just does not filter noise as well as the stock unit did. I can live with it but it really does annoy me. May try a noise filter on the alternator or somethin one day.

The pop is normal, it is the abs pump doing a self test.

Noise could probbly fixed with a ferrite bead on the wires

Never heard of such. Care to explain? And on which wires?

I also had the whine from the OGM-1. Mine turned out to be a bad wire from the backup camera. Once it was replaced, the whine went away. You will also want to verify all grounds are good. When you installed the OGM-1, was it just the head unit, or did you add amps and speakers at the same time?

How can a fly-by-wire pedal provide any driver feedback via a kick? I'm curious becuase I know the traction control in my Z28 can kick the pedal but it's controlled by old fashioned cables.

I have checked grounds and things seem fine. I have even cleaned them some just to be safe. How did you know the camera wire was what was causing it? I only added the headunit I did not add any speakers. I have since replaced the rear doors with some Infinity speakers though because one of the stock ones failed. The whine is really most noticeable when the headlights are on but it does it all the time.

My truck has had the whine only when I i start it up and give it some gas then it goes away. I also have the pop in the gas pedal. Both of these have been going on sense i bought it new in November of last year. I would love to know what cuases this.

I bought the OGM-1 and backup camera from Walt. When the installer installed the camera and wiring, and the OGM-1, there was an issue with the camera. It was not working at all. He took that camera out and connected it to an external monitor, camera would just do a quick flash, then nothing. He put the truck back together and I talked to Walt about it. On the trip home from installers and every time I drove the truck I would get a whine from speakers. Walt sent me a new camera, we tested it before installing it, and it worked. Installed the camera, it failed to work. This time we noticed that the lead in the harness that goes from radio to tailgate was warm to touch. Installer checked the wire for both continuity and power. Cable was bad. Talked to Walt again, this time he sent me a harness, and another camera. This time installer put the harness in, and we let it sit for a while to see if the wire got hot this time. He also checked the wire at the tailgate end for proper operation. We put the camera in, then it all worked as it was supposed to. And the whine was gone as well. Walt asked me to send the camera back the first time, and also the second time. I cut the end of the cable apart at tailgate end, and found the circuit board inside was burnt up. I included that piece when I sent the second camera back to Walt. He said he did not need the cable back, but I sent it anyways.

Sorry for the diatribe, but simply saying we replaced it did not seem to be enough.

 

BTW, Walt was extremely helpful and patient with me. He went above and beyond what he could have done. Anyone wanting to know what he is like to deal with need only read the above to see what kind of vendor he is. 100% different from the vendor that sold the group buy oil catch cans here. Thanks again Walt.

      OCI, not when but why?

      By PunchT37 · Posted

      My brother has a 2007 Avalanche with afm 5.3. It`s got 176,000 miles. Runs like a clock. Never been apart. Co worker has a 2010 Tahoe with afm 5.3. 230,000 miles. Never been apart. Runs like a clock. So, even though cyl deac is a weak spot, they can go the distance.   BUT, these engines had the oil changed regularly, AND had 5w30 as spec. I wonder if they would have lasted this far on 0w20? I`ll bet not.

      OCI, not when but why?

      By Chuck FB · Posted

      I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing.

      Tranmission stays in Low

      get a good code reader, and find out what problems the truck has noticed by reading codes. cheap ones can only get basic engine codes, you may want to get one that can get codes from all the computers in your truck.

      This is sort of my point, salvage yards aren't overflowing with all these 'poorly' maintained trucks - excellent/good/servicable condition otherwise, salvaged only as a result of a bad engine from poor oil change regiment.    In my area, there are no 2007 to newer gm trucks/suvs in any salvage yards. A few are in the 'recyclers' with very obvious reasons for being there - wrecked.

      Stabilitrak conversion to Z71

      By asilverblazer · Posted

      Stabilitrack was a stability control, traction control system, that functioned independently from the transfer case.   Z-71 has nothing to do with the transfer case or differential.   If it does have an AWD system, my memory recalls this being specific to the Denali trim, converting won't be as simple as swapping out mechanical parts like differentials and transfer cases. It will require reprogramming at a minimum. Long story short, not likely worth it.   Pulling a fuse, may disable the AWD system, it might also prevent any other transfer case functions.   However, the AWD case was generally based on the same transfer case you refer to in the 2006 Suburban. If it still has a 4-High and 4-Low where the transfer case locks and splits power 50-50 front to rear, what are you gaining by changing anything? A true-rear wheel drive only, what good will that serve? Not enough to go through the trouble of changing out all the parts.    Generally, all the factory systems will handle a 33" tire and re-gearing. Probably a 35" tire too, if you aren't driving like a caveman. If 35" tires are in the plan...   If you do plan on driving like a caveman or are fully committed to 35" tires, an entire re-think of the build is probably in order. Starting with square one, an IFS front end isn't going to be the best starting point for 35's and caveman driving.
