  1. There was numerous news reports of GM spending billions upgrading factories lately. Just Internet search on "GM upgrade factories".
  2. So how in the heck does someone fill to just 0.5in below the fill plug hole? No plus/minus range, exactly 0.500000 inch from the fill plug? Does the service manual provide some technique? Some special $$$ GM tool? Do I need a inspection camera to check? What do dealers do? I guess I could park front down on my driveway (light slope) and fill to the top, when the vehicle is level the fluid would be below the hole. Maybe a bent wire could be used to just the level? A little vacuum pump remove excess? Okay, I'm sort of joking, sort of... I'm sure I will get a "Just fill the top and don't worry about it" response. But still, I would like to do it best I can.
  3. With my 2015 2500HD Z71 4x4 6.0, stock tires, 65psi, averaged 15.7 on the highway. For a 400 mile day trip with some light mountain travel and a little local driving, 15 mpg average total. Weather a little rain, 55F. I'm a little heavy on the pedal and didn't use cruise control much on that trip (traffic)...
  4. When I was researching trucks, I would look under the Fords, Rams and Chevys. From my sampling, the Fords and Rams had a TON of rust on them (new trucks) just sitting on the lot. The Chevys had the least. (I'm aware of the frame rust issue, I just haven't seen it from my sampling). My old 2000 Tahoe was almost rust free. I do plan to spend some time touching up any minor spots on my new truck. Just because I like to see it clean/rust free. (Even if I'm the only one that will ever see it.)
  5. I assume "they" is the dealer as GM is not responsible for non-OEM modifications (even if done by an independent dealer).
  6. My 2015 Chevy 2500HD 6.0 with XM antenna, non-towing mirrors, but no roof markers is quiet. When I was researching trucks a while back, I remember a noise issue on some new F150's due to the windshield not mounted correctly. The fix was to remove and re-install.
  7. And Internet search on "12346501" (GM Part Number) brings up multiple sources...
  8. General reference information from http://www.discounttire.com/dtcs/infoTireBalancing.dos {Snip from above} Other Sources of Vibration Very often the wheel/tire assemblies on a vehicle may be in balance but you can still feel a vibration. Here are some of the other causes of vibration: Bent wheel Tire out of round (radial or lateral runout) Wheel-to-axle mounting error Inconsistent tire sidewall stiffness (force variation) Brake component wear or failure Drive train or engine component wear or failure Suspension wear or failure Wheel bearing wear or failure Wheel alignment is out Your tire dealer can isolate many of these problems for you, and there is no question that determining whether the tire/wheel assemblies are good and in balance is the first place to start. However, ultimately this may not be the source of your vibration problem.
  9. If there is any hardware differences (which includes the type of input/output data streams), then a full test sequence would be required (which takes resources from other projects). Plus a risk if they miss something and break a feature, then stuck with another recall which is not cheap. Frankly, I wouldn't expect any software updates unless a recall class issue and then only a minor fix to that area of code. (And never know when there are board/cpu/circuit changes to parts which impacts the software but transparent to the consumer.)
  10. And tell them.... "You can get anything you want at Alice's Restaurant".
  11. So the theory is the wheel(s) is/are shaking to the degree to overwhelm the shocks? Thus dropping the tire psi down 5 or so (as a test) should reduce the effect? Has anyone put their truck on blocks, removed the rear wheels, and run at the target vibration speed (with the axe spinning)? if it still vibrates, sure ain't the tires if not even on the truck. Of course if it doesn't vibration then it doesn't prove anything as still could be the drive train if it has a load on it. But if lucky, it would repro with no tires. Could mount an action camera pointed at each wheel (ie, four attempts with one camera) and compare them for any weirdness. If local to a single wheel, it should stand out when compared with the videos of the other wheels.
  12. From a F150 forum... {snip} "Anyone familiar with the process / success of lemon law pursuits? My new 2014 Lariat Supercab has been in the dealer's shop more than my driveway and they do not seem to be able to find the cause of my issue. I have a vibration at 35 - 40 MPH which they have thrown everything at to no avail (tires, driveshaft, axles, etc.). With only 1,200 miles and no obvious cause, I don't think I want this particular truck anymore, especially $40,000 poorer. Anyone with experience in returning a truck, I'd like to hear how it went with Ford. It's kind of sad that my 2000 Lariat with 330,000 miles rides better than the 2014." Interesting that neither GM or Ford has the ability to diagnose this type of issue (at least at the dealer level) without throwing parts at it.
