I immediately noticed it was wet in your video.. I have a 17 Denali and I have noticed that after I take it to the car wash (hand wash ) the radio screen blacks out (sometimes)... I called on star once when it happened.. they had me turn off the truck for x minutes and start it again. It was fine until the next time.. If it ever stops snowing and I get to wash my truck again I guess we will see if it continues but I’m confident H2O is a factor...

If it helps.. my Dodges radio used to black out when it got hot outside.. luckily I live in Canada..

Ok everyone here is the update. It has been a while since I have posted here about my issue. The dealership got a new fuse block in, they replaced it and still the issue occurred. They then blamed my HVAC Module, put a new on of those in. Still no dice.

 

Just this last week they noticed my headlights going dim then bright just like my instrument cluster. They told me they believe it to be my Alternator. Which I had told them on January 25th I tested the alternator and gave them my results. I was not very happy. If you look back to page 2 you see my alternator test results, IN JANUARY!!!!

 

Well the new alternator is installed now. It only took them 3 months to diagnose what I had already done months ago. I have not seen any symptoms since getting the truck back Friday. Lets hope that was it and the problem does not return. 

 

I would like to share my experience of this as well in hopes someone from GM reads my post. The dealership did everything right, except not listening about the alternator. I understand they are not allowed to fix something unless proven broke by error codes or GM tells them to. GM on the other hand was absolutely awful. I worked with 4 different advisors and was told they'd call me back on several different occasions and they missed the ball every time. They would call several days late with less details than I had. My shop was on top of it calling me and letting me know the progress every step of the way. Multiple times I had to tell the GM advisor what the shop was doing because they had no idea. I left about 7 voicemails throughout this adventure and my advisor responded to 1. GM, if you are reading this, please work on your customer service.

Hopefully this fixes your problem, glad to hear that your truck seems to be fixed!  I don't know how many times your vehicle was in for warranty repairs, but you can pursue a breach of warranty claim against GM to receive a reimbursement for lost value on your asset due to the spotty service record. My lemon law attorney mentioned that GM may offer that to me instead of a full buyback since my truck was used and sort of in a gray area (according to Ohio's lemon law). The breach of warranty is a federal law and pursuing a claim incurs no costs to the customer, GM absorbs all attorney fees. Unfortunately, that is about the only way you are going to get GM to listen.

 

I had multiple calls and voicemails to GM and was hoping to arrive at a mutually beneficial resolution before having to involve legal counsel, but GM's customer service reps never returned my calls/voicemails.

Hey all, I will start from the beginning here. Purchased my new 2017 Sierra Elevation Edition in February 2017. Drove it off the lot with 6 miles on it. This is my first new vehicle so its been a little discerning to me that this has more issues than any used car I have owned before. 

 

A few weeks after owning the truck, my microphone stopped working for my phone calls and the onstar stopped working all together. My OnStar module died and they replaced it with a new one. About 5 thousand miles later, my trucks radio screen started randomly going black, turning off all sound, then coming back on again. It would resume where it last was, phone call still intact or radio still on the right station. This went on for about 2 weeks then my dash lit up and chimed at me, the radio turned off like it does I get a warning of a Power Steering Failure. I call my local shop and get it in there right away. The drive in, the power steering worked just fine. 

 

They said the reading came back as High Voltage, they updated the computer and sent me on my way. Fast Forward to 3 weeks later, my truck starts doing the radio off again but this time the dash lights all shut off too. I can't be sure but it seems to do it when its wet outside. It did not have problems after I was in the shop but it was also dry outside. I also noticed when this happens the voltmeter spikes high.

 

I am dropping my truck off again the Tuesday after Christmas. Does anyone have experience with this before? The shop told me last time they have never seen this before. 

 

Thanks!

Hello, i own a 2015 chevy silverado. had many many electric issues similar in nature. my entire truck would shut down, lose all electrical power for a few seconds and than randomly restart and turn on. happened randomly and often, even while driving. my steering would also malfunction and the electrical steering would feel like it was resisting me and jerk around. i read a bunch of forums about the grounding issue behind the dash. the recommended solutions didn't help me and electric problems continued to occur. but i took it to a local maintenance shop and told them my problem and said that this is a problem concerning the throttle body. I have no idea how or why  but i'm assuming they cleaned it out and i haven't had any electric problem sense then. i have no idea how these problems relate but my truck hasn't had a problem for months now after they treated the throttle body. hope this helps

I’m having similar electrical gremlins currently. Power steering issues, brakes locking, headlights going crazy and check engine codes. Dealer put alternator in. Picked it up, more codes. Dealer put battery in. 1 week later, more codes. Now it’s been in the shop for 6 days and they’ve replaced the headlight unit but that didn’t fix it. I’m going in today to escalate it. Have already had fuel pump and wheel bearings replaced too. Bought new 7/2017 and it’s got 9000 miles left on the warranty. I’ve had it with dealers not being able to fix it.

I’ve had my 2017 Silverado 4X4 in shop 5 times, not including countless phone calls-even call GM directly, because my entire dash goes out, losing headlights, radio, hands free phone only to be told “we can’t duplicate the problem!” Once I was driving east on I 16 and had to pull off the road to call and they wanted me to come straight to their shop. It was 3 hours in the opposite direction at 5 pm! GM closed case because the dealership said they couldn’t duplicate it! Well, they had to know about the problem because the put a new battery in, then they changed the headlight switch, then they tried updating the memory, etc., etc. I have always been a Chevy girl, but at this rate, I’m rethinking Chevy!

Welcome to the site.

 

Have you considered finding a new dealership to look at the truck?

 

You can take it to any Chevy lot you like.

Yes, and they said same thing. If they cannot duplicate it, they cannot fix it.

If they are saying (multiple dealers) no fix, and if it has been in the shop for over 30 days combined, I would open a new claim with GM demanding a buy back.

 

You can also check the Lemon Laws in your state too, but would start with the buy back process first, takes a while, but no money out of your pocket for legal fees.

Thank you for that information. I was not aware about a buy back. I am not in the lemon law timeframe anymore (missed it by 2 months.

You are very welcome.

 

Call GM, open a new claim, and see what happens. 

 

You did not mention your miles, but if this has been a documented problem with your truck (dealer records), I would give it a shot.

      Towing In Loose Gravel

      With large equipment or deep mud it is more of a use the higher gear to avoid spinning tires, getting stuck because of spinning tires and doing damage to your machine. The idea is if you run out of torque before you spin tires you can still downshift for more torque. If you are just spinning your tires in the lowest available gear you are stuck and things break.   Automatic transmissions, traction control and electronic transfer cases change the calculation a little as you the driver have less control over each piece.

      My First Project and GMC has me stumped

      By davester · Posted

      are there any codes? with lots of rust, perhaps disconnect/clean both sides of the connection/examine cable ends (the wires) for corrosion going into the sheath & replace if necessary/reconnect ALL the power AND ground cables between the battery, engine, frame, cab, fuse box and starter charm.li (website) has a no-start diagnostic procedure you can work through to get it working.

      OCI, not when but why?

      By Chuck FB · Posted

      Its no wonder you've gravitated to the oil types and brands you have in later years after trying certain brands and one being a specialty oil or at least very hard to come by up here and the other would have been a commonly found oil of the era and the vastly different outcomes as a result to using the vehicles in question the same distance for an OCI . It shows what marketing hype can do without actually having the product to back up the claims and that is no different now with the insane claims that are written on the side of a bottle of oil from some of the off the shelf oils.    What has surprised me and I was already finding this out before I bought my truck with the GDI engine, that this newer fancy technology that seemingly would suggest better fuel economy/emissions with this high pressure spray of fuel is not in reality kind at all to the engine or at least the oils life. Yet they insist on claiming long OCI with this technology just like they did with the port or similar type fuel injection systems when in reality its a step back in oil life to have a GDI system.    I think the mistake your making Grumpy is that your not sending your samples to Blackstone and getting the feel good glowing report that you can run it another 1000 or more miles and then send another sample where they say run it yet another 1000 miles and on and on it goes until your sending in something that looks a lot like road tar and then they may suggest you change your oil within the next 1000 miles 😆

      By Chuck FB · Posted

      I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death.

      OCI, not when but why?

      By Grumpy Bear · Posted

      In the 80's 90's I'd run Honda's 7,500 miles between changes using Red Line HP 5W20 and do it for hundreds of thousands of miles with issues. Back in the day it was an SAE 20 with the HTHS of a SAE 30 and SN add load. It was also very polar. Oxidation VOA was over 120. Besides those motors were SPFI and lean burn tech. I could have likely run it longer but never did.    We had a Toyota bought new I ran on Pennzoil's latest and greatest synthetic of the day with "Penthane". A made up word for a very low dose of PAO. Tried 7,500 mile OCI's in that Group III/VI chemistry and the rings tapped out at 90K. Rocker box wasn't as bad as the one Punch put up but it wasn't good either. Also a SPFI motor.    I'm around 3,750 across the board on these GDI monsters and the oil it tapped out by then usually on TBN/TAN crossover and color. Red Line HP Euro.    The AMSOIL SS brochures tell you to follow the OEM values for the service class but that it can be run up to 25K if monitored. I can't imagine what motor could go that distance and not tap out. I've never owned one.    Yes, I know. Lot's of people do. I'm just not going to be one of them.
