It wouldn't be so bad if transmission wouldn't change gears to 2nd at 65 mph on the highway and cause the seat belt to choke ya. Or for the drive by wire throttle to cut in and out. Nothing like trying to pull out in traffic and thinking , is it going to do it again today ?
Thanks for your story , I'm going to keep researching this and posting more videos to see how many more people are having the same problems.
I went back in the thread and saw in your initial post that you have interacted with Customer Assistance already. I'm sorry that this process was frustrating for you, and would like to follow up further. Do you have a Service Request number (or the last 8 digits of your VIN, if not)? We would be willing to look into that again for you if you would please email us more details.
Thank you in advance,

I saw some other post about a event record being installed. When I asked for this from GM , I was told there was no such device and they couldn't do it.
Cost for diagnosis isn't too big a issue to me as fixing this safety issue and preventing a accident.
I was told there is little profit for local GM shops spending alot of time tring to diagnosis hard to find problems.
I will send you a email this evening. I have several videos posted online if you want to look. I am working on a longer one with more issues I have experienced. I look forward to hearing from you.
We had the rear wheels lock up this weekend for a few seconds , without pressing the brakes. Crasy.

It is great that you have these videos. I wish I had one when my brake lines burst(x2). I have posted your videos on my Facebook page and will ask friends to spread them around. Maybe this will get GM's attention. Maybe they will also pay attention and make it right for all of us that bought their trucks and paid thousands to fix their prematurely failing brake lines.
Good Luck, stay safe.

I know American quality is gotta be better than this.
My 1998 Silverado with 259,000 miles on the orginal engine is more trustworthy than this 2007.
If your hear anything on Facebook , please let me know.
Thanks.
This is true. What's also true is that GM has labor times (time allowed to change the part) that are impossible to meet also causing the dealer to lose money on hard to resolve warranty issues.
I agree , I have been begging for more technical help. The reality is , you will not get help unless a tech can see a problem. It can be tricky to do when a product malfunctions at random. Multiple, documented cases showing Video proof of a intermediate safety issue is not enough proof to get help.
Shops are pushed for production = profit. Spending time going into a system cost hours.
Sadly nothing will be done until there is accident or two , then some media and some attorneys will be looking for fame and fortune.
I tried to do some investigation using my resources as a Customer Service Representative, but was not able to find a clear cause behind the DIC issue you're describing. Some thoughts that surfaced included perhaps the ECM, but please don't consider this an official GM diagnosis as we rely upon our dealerships for that.
I realize you are just outside of the parameters of your Bumper-to-Bumper warranty.
If you were to get us an email with more information, including your name/username and contact information (phone and address), the last 8 digits of your VIN, the name of your involved dealership and current mileage we would be able to evaluate the situation further, perhaps even contacting your dealership.
Thank you very much,

Thanks!
2009 silverado LT, crew cab. 5.3L
Lights flicker with brakes, door locks intermittently freak out. Tonight lost power pulling out into traffic and without coasting truck up onto median would have wrecked. Precluded by wierd chimes and random downshifting. On two occasions two weeks apart, turned off ignition and all went dark and cold, similar to dead battery. On the second I used a jumper cable from negative terminal to frame and power came back. don't work.
Have seen several similar posts and cant believe this isnt a recall/extended warranty period item, a quick response and escape route is the only thing that prevented an accident tonight! Of course Im 9000 miles over warrenty... Electrical gremlins get very expensive very quickly - PLEASE HELP!
I've babied this thing since I've owned it, still looks new and has yet to see a trailer. Chevy, I've wanted a silverado since I first saw one, please don't let me down.... My wife has already uttered the "never again" phrase!
We could explore what options are available to you through a Customer Assistance Case, which are evaluated on a case-by-case basis and also add to the database that GM uses to make product decisions. If you are interested in this, please send us an email with more information, including your name/Edmunds username, contact information (phone and address, please), the last 8 digits of your VIN and current mileage, and the name of your preferred dealership.
All the best,
Sarah

Luckily I got it on video...
This time I'm absolutely positive the cycling locks and power loss was accompanied by ABS and Stabilitrack cautions. Also, of particular interesest, I am certain (as caught on video) the Airbag light momentarily illuminated - huge safety issue. A perfect storm of power loss at the right moment could lead to a crash where airbags don't deploy...
I found my negative battery cable to be a tad loose at the battery. Although it's tightened down as far as it will go I could twist it back and forth on the post.
For now (two nights ago), I've wedged a screw between the cable connector and post to tighten up the connection. Haven't had a problem since... (knock on wood). If all stays well for a few days, I'll investigate replacing the battery cable.
Here's hoping!
For the flickering headlights when the brakes are applied, my problem traced to a bad ground connection located on the front passenger frame rail, in-between the tow hook and the control arm. This flickering light also gave warnings of "Service TC" and "Service Stabilitrax". That problem hasn't come back yet.
Now, occasionally while driving, the power will flicker on and off. This constantly resets the radio, cuts all lights, lights the dash up like a Christmas tree, and occasionally will prevent the vehicle from starting again.
I believe that what I read on here about the hot spade connection under the fuse panel is the culprit since my battery posts are tight and clean. I'll check it tonight and update this tomorrow.
I'm not sure what would cause the truck to downshift hard and get stuck in 2nd until it the battery is disconnected. I'll keep reading through this site, there's alot of pages on here.
Thank you everyone for taking the time to input on this site.
Happy New Year Eh!
- Transfer case blew up due to a leaky case and no lubricant
- Windshield washer fluid heater removed
- Fuel pump and sending unit replaced due to spuratic fuel gauge readings
About the time the transfer case went out (28,000 miles) was when the fuel gauge started giving me a fit. I also noticed that sometimes when I started the truck up that the radio would not power up. I did figure out that when this happened, all I had to do what hit the eject button on it and it would power on. I knew I had an electrical problem then and reported it to the dealer both when they attempted to fix the fuel gauge problem at 34,000 miles and then again at 37,000 mile, when they did actually get it fixed. I was OK with the minor inconvenience of having to hit the eject button occasionally to get my radio to power up until last week when all went haywire. While the motor was running not only did the radio go out but the door locks, gauge cluster, interior lights and I think the heater all went out. Thankfully when I turned the motor off and back on again, they all came back online BUT now they flip on and off at very random intervals and nothing I do changes anything.
Electronically speaking, the guy I bought the truck from had LED running board and rear bumper lights installed and I have hooked up a set of spot lights on the front end, with the relays wired into the high beam circuit. I also have a Banks 6-Gun and Power Brake plugged in but nothing seems to change when they are unplugged.
Based on what I have read, I am thinking there is some connection that has let moisture in and is giving one of the ECM's a fit. Also, I am in Northern Alberta and all this when crazy just after we had our first cold snap of the season.
Anyone know where to start looking? The roads up here are real sloppy all of the time and the undercarriage get and stays wet just about all of the time.
Best,
Sarah

Buffed it all shiny, pinched the female end tighter, and packed it with di electric.
Sarah, what can I modify on my transmission and still have power train warranty? I'd like to get some corvette servos, stiffer shift kit and a billet Shift fork, but if that'll void warranty then I will hold off.
Thanks.
Any suggestions from anyone? Thanks.
I unbolted the wires from the frame and noticed a good arc. When I reconnected them with a good bolt that I borrowed from another part of the truck the pump located on the inside of the frame opposite from the ground (I think it is the fuel pick up pump but not sure) started to run. I have never heard this pump run before. As I got into it to see what was going on there I noticed it has a quick connect on it with about 6-8 wires going into it and since the cup of the connector is pointing forward, it too had a significant amount of road slop on it along with a good size block of ice trapped up on the frame around it.
Now that I have re-secured the ground many things aren't working (they worked before I tightened the ground) and the pump won't stop running (I disconnected the batteries)
Any clue anyone?
All the best,
Sarah

I am sorry to have taken so long to get a response to you! Sometimes our tool doesn't get posts to us, and I was cruising through Edmunds and found this one. So again, apologies.
For your warranty question: Technically any modification to the vehicle can void the warranty, but a good rule of thumb is if the mod can be linked to the concern, it will not be covered. In my experience, if a vehicle concern does arise the dealership will first seek to bring the vehicle back to stock as a first step in trying to diagnose the source of the problem.
I hope this is helpful for you,
Sarah
