I believe my issue has been resolved. Tomorrow will be one week that I have had the truck back after the dealer replaced the starter and, I think, a battery cable. It has started every time. It has been sub zero temp..no prob. Prior to this it was almost like clockwork. Leave the truck in the cold long enough and it wouldn't start. The dealer told me that GM was aware of this issue and suggested what parts to replace. Hopefully they have, via a TSB or other media, gotten the word out to their dealer network. I've seen so many people on here that take it to the dealer, and nothing gets done because the dealer can't replicate the problem.

I picked up my truck last Friday from the dealer after dealing with the same problems. They told me that GM had told them to change the starter and (I'm guessing) at least one battery cable. It was my salesman that told me, and not being a mechanic he phrased it as "the starter and something else with high resistance". That it why I'm guessing that what he was referring to was a cable since somebody else in this forum had a battery cable with high resistance changed as a result of this very issue. It has been sub-zero overnight at least one if not two of the nights since I got the truck back, and the highest temp has been today at about 25. The truck has started every time. Prior to, every morning it wouldn't start. Almost every day after work it wouldn't start. I would try, wait, try, and it eventually would. I'm feeling pretty confident that they have fixed the problem. Add me to the list of guys that had the problem, got a new starter, and have been good since. The OP I believe is on that list as he hasn't come back indicated that his issue has come back. This talk about the flapper valve is absolutely, completely not related to the non-starting issue described in this thread. The flapper is a purely mechanical device that has absolutely nothing to do with allowing the starter to turn.

Mine started the morning after I bought the truck with about 50 miles on it. ***maybe I should rephrase that*** Mine started ACTING UP the next morning after.

Thanks..mine is at the dealer now waiting for a new starter. Last week it was a daily routine...wouldn't start in the morning. This is the 2nd time in the dealer, maybe I should "look" at mud flaps when I go pick it up :-) Sent from my XT1055 using Tapatalk

Did you already have a new starter installed or had you been waiting for them to get one in stock? Sent from my XT1055 using Tapatalk

Took mine in this morning. Told them about you all having new starters installed and indication of a bad batch. They lifted an eyebrow and said they know of a problem with the 13's having bad starters but not 14's. I have a loaner for now while they try to diagnose it. I will post here the results when I know more. Sent from my XT1055 using Tapatalk

This may be something that's been going on longer than we think. This review by autoblog.com back in July had the same problem. http://www.autoblog.com/2013/07/29/2014-gmc-sierra-review-video/

Right on, what did dealer say when you took it in?

Curious what the dealer had to say about yours. You mentioned the exhaust flapper but I believe that has to do with the truck not starting/running well when cold, but not related when the starter doesn't engage.

Thanks for that, answers all our questions.

That's from captKev, not SSimpson, the OP

Read OP, nothing about temp there.

SSimpson, is it cold where you are at?

Did it crank when it wouldn't start?

I'm anxious to hear what the dealer experiences and what they have to say. giloma - when yours wouldn't start, did it even crank? If not, the jump start might not have really been needed. As with my issues, you try to start it and it just clicks (no starter activity), wait a bit and try again and it fires right up. The batt is strong. It may have been a result of the timing rather than the jump starter. OR... you had a low battery

Similar problems again this morning. Wouldn't start with OnStar nor the key fob. It was about -3 this morning, sure would be nice to have a warm truck to get into. It's beginning to appear that after the truck has sat overnight or for an extended period of time, maybe temperature related, is when I have these problems. This is not a battery issue, the battery is strong. When it finally does crank it does so just fine. This morning the electric power steering wasn't helping much either. Very stiff. A week ago I was pee my pants anxious to get this new truck. Today, I wish I never did.

Been around 0-20f here

Exact same problem here. Had the truck 5 days now. Either with remote, onstar, or key it seems to have a mind of its own. Same thing when I took it to the dealer yesterday.

I read about the flapper but that seemed to be related to a hard starting situation where the starter was actually cranking the engine. In my case, it could be described as a starter solenoid that is going bad. The starter doesn't even engage.

Just picked up my new 14 last Friday (5 days ago) and have had multiple occurrences where the truck will not start. The typical scenario has been like this: 1. Attempt remote start either by key fob or the OnStar remote link app. If using the key fob, the parking lights flash to indicate that the remote start request was received but the truck does not start. If using the OnStar app, I receive an error message that the truck could not be started. 2. Attempt to start the truck using the key and...click.click. 3. Get out of truck, throw something, say a few four letter words 4. Try again with the key and it magically starts. The new software was loaded in the truck as I was in the process of negotiation during the recall and had to wait for the update to come out before the dealer could deliver. I went straight to the dealer yesterday morning after this happened and they have no explanation to what the cause is. They reprogrammed the keys/fobs. I also was carrying my 2nd set of keys in the console, which they suggested could be the cause of the problem?? So I took the spare set of keys out of the truck and crossed my fingers. No such luck however as it happened again this morning. Anybody else experiencing anything like this?
