Remote start not working correctly

New '07 Hoe and my remote start will not always work.  It is an intermittant problem that seems to be related to how cold it is outside.  When I try to remote start it, it fires up and dies.  Once it does that, you cannot get it to try again.  Took it to the dealer and they say there are no error codes and they could not get it to do the same thing.  When it is 20 degrees or less I notice it does not start about 1/2 the time.  Kind of makes the remote start useless!
 
Anyone else having this problem, or know how I can correct it?

Well I guess the obvious needs to be stated before anyone can help. The remote start from the factory has a horrible range, are you close enough to get it to start? The remote start is also designed to run for 5 minutes and if you hit the remote start again it will prolong it for another 5 minutes for a total of 10 minutes. After the ten minutes that truck won't start again. Could any of these designed issues be part of the problem?

Nope, this happens whether I am 100' away (at work) or 10' (starting it in the garage).  I do know that it will only run 5 minutes, but it does not even start.  It will turn a few times and die.  Kind of like a carburated '82 would have done in the cold...once it dies, you can unlock, re-lock and try again but after that you cannot try again.  I guess it only gives you 2 tries.  I know that I am holding the button long enough, just not sure what might be causing it that the dealer can't find any codes on.

If you use the key does the vehicle run and start normally? Have you checked your battery terminals to see if they're tight and have no corrosion. If so, it sounds like an issue with the remote starter brain.

I know what your talking about...my Mailbu did the same thing just yesterday, fired and died and would not fire again, I did not take it in yet (LOL I work ata dealership you would think I wold have)..I have heard some ppl haveing issues with their body control modules for their remotes and windows and locks, mostly on the Uplanders, check that let me know.

I can say its not temp related it was -46 here last week with wind chill and it fired no problems, forgot to plug it in to.....ouchy...anyhow it was only like -10 the other day when it did it.  It will start fine with the key..ALSO mine gave a check RKE code which is the security system, I putting my money there as the, the Cstart is tied directly to it.
 
couple things Salesguys should be telling customers, they only have a 200 foot range can only be cycled 2 times and wont start a 3 and runs for about 8 minutes each time.

Starts just fine with the key, needs absolutely no help.  Nothing else is working odd, all locks, key fob, etc is working fine.  Checked battery and it is fine.  Only have 3500 miles on it.
 
MalibuMaxx- man that is cold, I grew where it was that cold (Idaho), no man should be made to live in such extremes! 

My 07 use to do it when it was over 100 degrees here is Vegas.  I took it in and they said all checked ok, but it only seemed to do it once the car sat for hours in 100+.  I use to unlock the car, lock it again, then it would start ok.

Mine has done that a couple of times.  It's on my punch list for when it goes in again. 

Mine has done it numerous times.   I live in Dallas and whether its 80 degrees one day and 20 the next it does it the same amount of time.  Does anyone know the fix to this?

Mine just did it again this morning.  Tried it twice, failed both times, so I walked out and started it with the key.  Few hours later I tried it again after being parked and it fired right up.  Seems to me to be related to it sitting and not have fuel in the chamber, so to say.

Try hitting the unlock the required two times a little slower and delay each step so that you finally hit and hold the start button a longer time after you first start the sequence.  Remember the fuel pump needs to be activated.  I'm assuming that the first unlock in the sequence gets several systems turned on and you may be trying to fire it before the fuel is available.  I know unlocking and opening the door activates several systems and maybe that's why it starts with the key.
 
Get it looked into but try this in the mean time.

My manual says to press the remote lock and then press and hold the remote start until lites flash or more than 4 seconds if you can't see truck.  Also says will run for ten minutes on first start and can be extended for ten minutes after which it must be started with the key.

This is definitely a problem, as I too have been having this happen.  Originally something told me it has to do with the colder temperatures, as that's the only variable I've been able to point out in troubleshooting the problem, but like LVHoe07 I too am in Vegas for the time being, and it snowed the other day and I was able to remote start.  So that throws the temperature theory out the window.  My 07' Yukon has had electrical problems right out of the gate, and with this I'm finally isolating the problem down to the remote start module.  I can go weeks without using the remote start and I don't have any of the electrical problems.  Sometimes I'll remote start and get into the truck, turn the key, and the radio head-unit won't fire up.  It's like the truck's electrical system or computer still thinks it's in remote start mode.  Also the rear parking assist will turn itself off.  The only way to fix it is to turn off the key, open up a door or something, then restart the truck.  That usually clears it up.

This morning my truck wouldn't even remote start at all.  The lights would register, I'd get in the truck, and all indicators would lead to believe that it was running, but it wasn't.  Then I'd hit the center key on the remote to turn it off, and all of the electronics would power down as if the car shut itself off.

I'll keep everyone posted on what I find out.  You all please do the same.

The RVS system will not operate if any of the following conditions are present:

Thanks for that as always!!!  Man there sure a lot of variables there huh.  A lot of things can be faulty or "buggy" to stop the remote start from functioning.  Makes it difficult to troubleshoot.

Dumb question now: We have a valet mode?  If so how does it work?

I did a quick copy and paste and didn't take much time to proof read this.

No "valet mode" on the Tahoe, we're trying to find the dummy that wrote that so we can take a toilet brush to his behind.

It should read:
•  Remote start feature is disabled in the DIC

So ZX1100F1,

Any thoughts on what might be goin' on with everyone's remote start, based on what you've read so far?  I ask because mine did it yet again this morning.

Well, we're out in cold Idaho for the holidays so I have been playing with it quite a bit.  Seems the trick is that you have to unlock it (to get the brain working) and not just lock it and start.  Mine sits in the garage unlocked, and when I lock it and try to start it, it fails more than half the time.  If you unlock, lock and then start, it has worked every time.  Guess it's just another wierd quirk they built in...

I will definitely try that from now on.  Good stuff!

I know this is an old post but I have the same exact problem with my recently purchased Tahoe.  Anyone find a fix?

See Post #18. Does that help your problem?

This is the first GM car that I've owned, and I really like it.  I do have to say though that it does have electrical (LAN) problems.  I picked up the truck from the factory in September, and I still have this same problem along with other little things.  Sometimes my power seat will just stop working until I "restart" the truck (LAN).  I wish there was a definitive fix for all of this.
