Hey everyone almost 1 year ago I bought a 2014 gmc sierra rcsb z71 5.3l. For the first 3-5 months I loved it. Then I started having issues with the service engine light coming on and off, after taking it to a dealership they said nothing was detected. Shortly after that I started hearing clunking noise in the rear end and was told by a different dealership it's normal? Well last night I was driving home here in michigan and I hit a slick spot in the road from all the snow melting. I was doing about 50 mph and the rear tires broke loose and started spinning which caused the traction control to kick on. When the tires gripped back up the rear end made the same noise I have been hearing and violently shook the truck to the point the headlights turned off, 100% of the dash went out and the engine shut off. Right after everything including the engine turned right back on but the wipers and radio were going crazy. Worst thing is the electric power steering pretty much froze up and almost took me off the road and through a ditch! I am fed up with this truck their is simply way to many problems. Only problem is I've had it almost a year now and I'm not sure I can just say hey I don't want it anymore. Which I completely understand. The other thing is the 2 most trusted dealers in my area have not been able to help in any way. Is their anyone else having this issue or anyone who can assist me with this issue? Any help is appreciated. Thanks.

Man that is unreal. I am sorry to hear you are having that kind of problem. I would try to contact GM directly or the BBB and attempt to get a buy back. And for a dealership to tell you a clunking noise in the rear end is "normal" is just beyond ridiculous.

Yes it is rediculous. The service advisor I spoke with said he sees it all the time and its the pinion tolerances. Thanks for the advice I am going to get ahold of GM in downtown detroit to see if something can be done. I simply do not feel safe in this truck after that. Especially with all the problems GM had recently. Sucks because I am a die hard GM guy and this is my 4th GM truck. But it is what it is and this truck just has issues and is not safe. For the steering to lock up the way it did with the key in the ON position is just beyond me. I thank God nobody was with me and I was able to avoid a crash. Thanks again man and happy thanksgiving!

Well I have a response from gm. They tell me to take it to another dealership.

 

UPDATE- GM has contacted a dealership for me and it seems they are willing to over see the diagnosis/repairs. At this point I won't bash them anymore, or give out any info on the dealerships I had a problem with unless this situation does not get resolved.

 

If anyone has any input or possible info on my problem please let me know. Thanks.

I know this is not related to your issue, but how is the chrome holding up on your wheels? I know Michigan uses some harsh chemicals in the winter.

Not bad actually. Their is a few SMALL blemishes but I bought them used so I don't know the history on them and if the previous owner took care of them. I do keep a nice layer of wheel polish on them though to try and chemicals and grime off the chrome itself.

I'm curious to find out what they say about your truck at the second dealer. I actually came to the forum because I have had a similar issue and it happened 3 times in two days. The thing that scares me is that I was driving on dry, flat pavement and never lost traction that I am aware of. The only difference is that I don't hear any noise coming from the driveline.

 

All three times my truck suddenly had a message that said "stability control" on the cluster, it locked the front left wheel, I lost all steering, the radio and cluster went completely dead and then the engine stalled about 5 seconds later. Everything came back on twice and the third time I had to restart the truck.

 

I took it to the dealer. They have had it since last Tuesday when they opened. They told me they can't find anything wrong with it. When I got there, he began reading the report from the scan tool and said "lost communications to steering, lost communication to brakes, there are a bunch more. I won't read them all to you". They wanted to give it back to me. I told them to keep looking. I don't want to risk injuring or killing someone else or myself.

 

Keep me posted on what you find out. I don't know if it is the same or not, but it might be related.

Wow sorry to hear your having issues as well. My rear end noise I have been hearing is the same clunking noise others are complaining about, I don't think it's the cause of my issue I think when the truck regained traction it was enough shock to make the rear end make that noise again. I havnt had time with work last week to take mine in but it's going in tomorrow morning to be dropped off. I'll update with the out come. I'm hoping it can be resolved as I love the truck. But at this point it's a risk driving and could car less how much I like it.

Well took my truck in and they claim they can't find what's wrong even though the computer readout is saying that their has been multiple power failures and power steering failures. They said that the best they can do is continue to search until tomorrow and if nothing was found that I would have to pay to have the mechanic continue!!!!!! Then the advisor continued on to say that my AFE intake may be a source of the problem! Really!?! A cold air intake can make a car shut down completley???? I can't believe this is real. How can a car company do this to people and not have any consequences? Unreal screw GM they just lost a customer who has owned more then 10 GM vehicles in the last 7 years.

You do realize that GM has absolutely no control over the dealership. If the dealership is being lazy that is on the dealer. That is the price we pay when the .gov people wont allow the manufacture to be the end point seller as well in the USA.

Yes I do realize that. I have personally contacted gm headquarters downtown detroit and they are the ones who told me to take it to another dealership which I did. Now I have to pay to have their mechanic look at it? I could understand if it had super high miles, or something I did wrong. This isn't a minor issue my vehicle is cutting off at all speeds and is clearly coming up on their scanners I have the print outs.

FYI... There is now a service bulletin/repair procedure for diagnosing and resolving the Stabilitrak/Power failure issue. It is # PIT5405A. The dealer had my truck for almost two weeks and worked extensively with the GM Technical Assistance Center (TAC) to troubleshoot the issue. They were finally able to come up with a procedure to diagnose the issue. This also allows them to confirm when the issue has been resolved.

 

I spent about 30 minutes talking with the dealership after everything was fixed. This issue is caused by a voltage drop in the electrical system. They can re-create it by applying voltage to specific points in the system. Once everything was corrected on my truck, they could no longer create this voltage drop, so I feel "fairly confident" that the issue has actually been addressed.

 

The notes on my service ticket were very extensive and they gave me the GM TAC ticket number as well so that I would have it for my records. I also got a print out of all of the vehicle logs for my records. I don't think they would have been as open with all of the information if they weren't confident that they had resolved the issue.

      2012 Sierra 1500 AC issues

      By Fishbones · Posted

      I just started having AC issues with my 2012 Sierra. The symptom is blowing warm air on all vents.  Here is what I have checked so far. Compressor clutch appears to be engaging and cycling  I checked all fuses and relay, no issues. The only thing I have notices is the short line that comes from the firewall is very cold / frosted. This line is approximately 12 inches long. The coldness stops when it hits the first line connector. As far as AC compressor - At first start the clutch engages, runs continually, Short AC line frosts up. After idling for several minutes the AC line thaws out some but is still cool and the compressor clutch starts cycling on and off every 5 seconds.  Any suggestions on what to look at next would be appreciated.

      OCI, not when but why?

      Unless you are using a bypass filer system with a Beta of 1000 at 2 micron the commercial filters we have access to, even the very best of them, are poor at the 5 to 10 micron range the typical UOA test can 'see'. Point is there are some truly awful filters being sold A 45 micron Beta 75 filter is what Dyson used to call a screen door on a submarine. That leaves wear metals disconnected from filtration unless particulates are larger than the test can 'see' and yet captured by the filter...which is its job. If that is true then you have a major issue screaming at you.    The graph isn't mine. It belongs to GM and their study on this area. I looked up those studies and provided those SAE tech paper addresses multiple times. Machinery Lubrication displayed it and confirmed it. So if you have doubts about the study you'll have to take it up with GM Engineering. Just like you would have to take up a difference in opinion about the meaning a word with Webster or the length of on inch with the National Institute of Standards and Technology.      Most manuals have two schedules. "Normal Service" and "Severe Service". On it's face it tells you that oil in severe service is more highly stressed and doesn't "Last as Long". The item to bore in on is LAST...what does that mean?    It's the same question one asks about how long to toast bread. What are the inputs? Bread type? Wattage of the toaster? Distance from the elements? What is your preferred level of done?    So lets paint this with a broader brush. Oil is made up of the base and the additive package. The first is altered by heat and oxygen and later is sacrificial with a finite life subject to inputs toward that end. Resistance and supply.    It is the reason an OEM's OCI's are determined by 1.) the specifications of the recommended lubricant and 2.) risk management toward the bottom line. Those lubricants are also subject to cost effectiveness for the OEM.    There is a tendency for most people to believe that the OEM recommended oil rest on the top shelf and that anything other is lesser than. Truth is there are more oils on higher shelves than those on the lower shelf below the OEM's. They make that choice on COST TO THE OEM. Testing is incidental to the margin.    GM makes MONEY, the car/truck is a TOOL to leverage MONEY. Insert whatever car brand you like. Until you forking over a million plus COST not quality is the driver. Thus it is by DESIGN the recommended OCI's and oils fall well short of 'best practice protections'. Proof isn't hard to find. GM Ecotec I-4 2400 breather system and cold start PCM tuning has killed more motors and resulted in more litigation for those that used the 'recommended' practice than GM could bear. What was their response? SHORTEN THE OCI. TWICE.    I don't know how long to leave oil in an I don't know how the oil will respond to MY circumstances and because I don't and can't blanket statement or anecdotal evidence my way out of it.....I TEST and FIND the right OCI for the oil I CHOOSE. There is no shortcut but there is blind allegiance. I don't blindly trust anything.    People hear the word 'detergent' and believe that in the context of oil it means the same thing as laundry soap... Only in the most rudimentary way. It's the first additive to give up on you and they are putting less and less with each new API standard. Solvency can be used but it cost. Some unique undisclosed chemistries can be used. Valvoline R & P in example. OEM's haven't an interest in anything they see as limiting market participation. Whatever.

      OCI, not when but why?

      By KARNUT · Posted

      For some unexplained reason my father wanted a salvage yard. As we were getting the family business off the ground one brother ran the salvage yard. We gathered there when rained out working on pipelines in the eighties to pull parts. Perfectly good running vehicles would come to us simply because they wouldn’t pass emissions inspection. We were able to swap parts and sell some of them. I got a clean old nova with a bad engine. I pulled a perfectly good small block out a Camaro. A father and son project with a rebuilt engine. The son couldn’t get the engine running right. The problem was the spark plugs weren’t gapped. The 90s vehicles probably widened the gap of shade tree do it yourself engine repair. My do it yourself hot rod repair stopped at the 70s. After that my trusted mechanic kept them in running shape.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      I have an old dental chair in my shop. Something I got for free and apparently it has more than scrap value? People collect them although mine isn't restored or anything. It's visually interesting (1930's Ritter) which is why I like it. And it IS decently comfortable if you kick back.   When a good buddy of mine saw it he said, let me guess, Atlas. It's a conversation piece? As in, you ask the questions, they do the talking?   Where do you hide the jar of teeth?   I would never.

      Are we talking about the same thing, though? The 7 versus 3 wear metals was from Lakespeed's 3.0-specific oil brand comparison test between AcDelco oil and Mobil ESP. The filter remains a constant so whatever excess particles the AcDelco oil is producing aren't being filtered out.   I'm assuming there's a parallel comparison to be made; IF the filter can filter down those particles, engine life increases, and your graph makes the case that a better filter (lower micron rating) can increase engine life. Introducing fewer particles AND filtering those particles with higher efficiency is the best of all worlds. Good oil, good filter.   Where we may disagree is the "baseline relative engine life". I'm more apt to believe the base engine life value is 200k+ on very average oil and filters, "bulk oil of unknown brand and white-label generic fleet-grade filter, Jiffy Lube"   Going from a 10 micron filter to a 5 micron filter should boost a base 200k to 275k in a vacuum as a single factor alone.   Here's the whatabout: How does regularly changing the oil and filter ahead of recommended schedule influence baseline engine life? Most people aren't going to science the heck out of this stuff or ask about Micron ratings, HTHS, or wear comparison tests at Jiffy Lube. Most of the Jiffy lube techs would say they need to call their tech support line to even try to get an answer.   --   Because we love anecdotes here, when I was fishing for 4.3 parts at a local yard this weekend, ALL of the 4.3 vehicles had well over 200k. I love looking at odometers of junked vehicles. How far did THIS go before landing at the crusher? The ones that still had engines weren't seized. None of them were vehicles I'd consider were Amsoil queens, in fact most of them had some kind of service cling-sticker in the corner of the windshield indicating it probably had very average maintenance services. Even the fresh parts rigs- I'm not sure taking an S/T series to 400k has much value considering the running value of those vehicles was probably somewhere around $1,000. 25+ years is a good run on time alone.   The intake manifold I salvaged had clean and bright pool areas. As expected, I found the fuel lines in the manifold rubbed through, just like mine. I'm guessing the lines on that donor truck started leaking, the truck started running rough, and its owner said that's enough I'm unwilling or can't take it out of service for several days, or spend $1000+ to repair it at a shop, it's simply time for a newer more reliable vehicle (or, more than likely, this is the 2nd, 3rd time this has happened in the truck's lifetime). While I don't count on my Blazer for reliability, the thought of giving it away for parts at certain points during my adventure, and being mentally free from its needs has has crossed my mind. I'd be losing $1500 or so, but I can only make more money; not time.
