I have the unliited data plan with OnStar for $20/month. It's just for the Wifi only, no other services. A few months ago, I noticed that my signal started becoming very spotty. In places I normally had good wifi strength, I wouldn't have signal at all. I've been on the phone with Onstar a half dozen times about it and we've gone through all the trouble shooting efforts as well as trying to connect on multiple devices to make sure it wasn't my phone. Then, about a month or so ago, I lost Wifi altogether. I mean, my phone (iPhone 12) couldn't even find the server anymore. Again, tried with multiple devices. Nothing. After running several tests, OnStar recommended I take it ot the dealership for a hardaware diagnostic check. $150 bucks later, they said it seemed to be working fine (although no device could locate the network). The onboard unit was, however, finding all the other wifi networks in the area. Finally, they told me they thought it might be the communications module ($399 for the part plus another $300 for the install). I asked what if they replaced it and it didn't work? They stared at me like I had 3 heads. Anyone else have this issue? I did buy the extended 72 month, 72,000 mile warranty when I bought the truck new from the dealership in August 2017 but it's expired (86,000 miles on the truck), so it's looking like I'll have to pay the $700 bucks unless I get any other suggestions.

I recently had some Recon roof marker lights installed, but now when it hit about 75 MPH or so there is a very loud and noticeable vibration (buzzing noise) coming from the center light. The lights are contoured properly and so seem very aerodynamic. When I open the sunroof while driving to see if I can figure out what's going on, the vibration stops. I have checked the seal to the roof of the truck and it's solid...not loose at all and no leaks. The seam across the front of the light where it attaches to the roof is very strong with no visible "pockets"., and when I try to rock the light back and forth, it doesn't budge. Any thoughts? PS - I tried uploading a couple of photos, but it's not letting me for some reason. I've double checked the file type and size and both are accepted and well under the 4.88 MB limit so not sure what's going on...

Right...but, in this particular situation, the battery hadn’t completely gone bac. It had just lost some juice. After I jumped it with my wife’s car, I drove an hour and cut it off. It sat there for about 4 hours and then started right up. That tells me the battery was just a little low. All I am after here is what size (in amps, I guess) portable jump starter I need to make sure I have enough juice to get it going? Obviously, if the battery is completely dead, no amount of amps will start it. My assumption is that a battery dies over time and so I just need some recommendations to get it going in emergency situations.

Gotcha. So I need to invest in a battery tester and hook it up to each battery to see which one is bad if/when this happens again? (Note: this seems like a lot of work at 4:30 in the morning when I’m trying to get into the woods for the morning to go deer hunting...LOL!!) I just want to jump and go (if that’s possible) and take the portable jumper with me so I can start it again if necessary. I know it’s not a long-term solution and I’ll get the battery replaced as soon as I can. I am just looking for an emergency situation, temporary fix. I appreciate your input!

I got both batteries replaced so I’m good now. I just want to avoid this issue in the future, so want to buy a jump starter big enough to start my truck if one of the batteries does in the future.

2017 GMC Sierra 2500 HD (Diesel) Last week, one of my batteries died. (I am embarrassed to admit that I have had the truck for 3 years and only just learned that it has 2 batteries! This is my first diesel...obviously). Anyway, one tested at 12 and the other only at 10. I ended up replacing both because I had heard if you only replaced one, the other one would “pull” against the new one and wear it out faster. Anyway, when it wouldn’t crank, I got our 1,200 amp jump starter (freshly charged) out of the garage and hooked it up. It wouldn’t start it! I left the thing on there for like 10 minutes...nothing. I had to back my wife’s care up and jump it off using that. I want to buy a heavy duty starter capable of starting it. What do I need? I see thy make 1,500 and 2,000 amp units. I assume those are powerful enough? What do you have and do you like it? How much did you pay for it?
