Agreed...had a similar issue about a year ago... Sent from my LM-G710 using Tapatalk

Not only the 14s and 15s. My 2016 hmi module bought the farm as well, recently. This issue seems a bit more prevalent than we think. Sent from my LM-G710 using Tapatalk

Not sure if this applies to any of these codes.... I had remote start fail due to a faulty throttle position sensor...(?) Sent from my LM-G710 using Tapatalk

If you paid by credit catfish, dispute the charge. Trust me, they will contact youngster that... Sent from my LM-G710 using Tapatalk

Yes, most likely. Happens to mine during inclement conditions occasionally. Sent from my LM-G710 using Tapatalk

I had the black screen. Just eeked in prior to bumper to bumper running out. They tried a new hmi cable, and ended up replacing the head unit as well. Keep up the good fight. This issue, if both the hmi and head unit need fixing is most likely well north of $1000. Best of luck. Sent from my LM-G710 using Tapatalk

Looks blue to me (?) Sent from my LM-G710 using Tapatalk

Sounds suspect to me. My camera failed under warranty. They replaced it, and all worked well afterwards, immediately.... ??? Sent from my LM-G710 using Tapatalk

Happened to me too. Hmi module. Sent from my LM-G710 using Tapatalk

1. Good for you. Glad you got this irritant resolved (on your own). I am ocd and would have lost it over something like this. I feel your previous pain. 2. As far gm figuring stuff out....i am batting about .600 with dealerships figuring out legitimate warranty issues that are their issue / responsibility. Sad fact: get used to that. Ref your issue/scenario: been there, done that, got the t-shirt. Case in point : my nav head unit bought it some weeks ago. D-E-D dead. They replaced it. It was acting wonky as hell after they did though, so they told me. Kept it 3 days, no resolution. Insisted on taking it home. It was wonky, that was true, acting bizarre, but working to some degree. Disconnected battery overnight. All normal since. Don't ask me why. That worked. They didn't try that in the 3 days they had it. No judgement. Just observation. Is what it is anymore.

Try a little pb blaster at the base? I know it can't flow uphill, but, sounds like you don't have much to lose... Sent from my LM-G710 using Tapatalk

Well, seems like the memory is the second thing to go.. Forgot what the first one was. Sent from my LM-G710 using Tapatalk

Agreed. The shake would show up on a test drive... so you can eliminate that one easy enough. I have a 16 slt premium+ 8sp 5.3. Only real issue was this week. Nav head unit took an uncerimonious dump. Warrantied thank god. No vehicle is immune from issues. Choose wisely, test drive first, pull a car fax. If it all adds up...enjoy.

Agreed, a perfect synopsis. Do what you wish, assess the risk, make a decision based on that risk assessment. Sent from my LM-G710 using Tapatalk
