  1. Envoys/Trailblazes with the factory 3rd seating (last year was 2006) where 16” longer and had a higher roof line for the 3rd row seating.
  2. Says you have a Denali and the front camera is mounted beside the rear view mirror.
  3. Look at Curt, they offer Class V hitches with higher tongue weights.
  4. This kit is all 3 metal skid plates - https://accessories.chevrolet.com/product/2016/Chevrolet/Silverado 3500 HD/front-underbody-shield-kit-23294258?categoryId=12001 You can get just the front skid plate only, GM dealer wants around $185 for it. Might have to look up a GMC with the All Terrain package. Part numbers I used about a year ago after replacing 2 plastic ones due to cracking - GM 23234433 GM 23269406 Confirm with your dealer before ordering that they are correct part numbers.
  5. Not a problem. I had a 2009 Silverado 2500HD that would get that code all the time. Replaced gas cap and that lasted about a week or so. Then replaced the purge valve and that lasted for a few months. Code would come and go all the time. Sometimes I would reset it and other times it would clear on its own. Don’t know what the actual fix was due to trading it in.
  6. It could be anything with that code. Gas cap, vent valve, purge valve, hoses, cracked sending unit etc... Best bet is to get it smoked, if not then you are just throwing parts at it.
  7. 2015 vs 2017 2500HD Towing Differences

    GM now meets towing standard SAE J2807 and I believe the 2016 model year was the first year.
  8. Going to need the code read to see what the problem is. In the meantime, head over to Duramax.com forum for others with CEL with less miles than you have on 2017’s - http://www.duramaxforum.com/forum/2017-l5p-duramax-powertrain/
  9. LP5’s is on the driverside under the cab.
  10. There are plastic clips on the cover, they clip around the perimeter of the grill. If you go the Chevrolet's website and lookup the diesel manual, it will show you how it attaches.
  11. Do have factory gps and if you do, is it working? Is the lights green in the mirror of onstar? Could be the onstar antenna
  12. Chances are yes it is the onstar antenna. One on my truck was replaced about 2 weeks after buying it and that was almost 2 years ago.
  13. Only difference in warranty with a Duramax between 2015 and 2016-2018 is the maintenance visits. Went from 4 down to 2. Everything else stayed the same. It is gas engines that the warranty was reduced on powertrain.
  14. XLT is a trim package on Ford trucks, not GM trucks.
  15. My 2015 Denali also came with a nice leather case and assumed they all came with one.
