  1. Steering calibration is now available at dealers to repair the majority of these issues. The service bulletin is not up yet so all dealers may not be aware.
  2. Do you have a high optioned trim? SLT or higher on GMC, LTZ or higher on Chevy? If so, there is a service bulletin coming directing dealers how to fix. Should be available next week.
  3. Is the vibration in the steering wheel, seat/floor, or both? #iworkforGM
  4. If the dealer did the proper fix for P02EE, I believe there is a new ECM software with a forced regen. #iworkforGM
  5. Pulling typically is a cross caster or camber being too high or tire ply rat issue. If the steering wheel is off but drives straight, the toe is off.
  6. Are the trucks pulling or is the steering wheel off? #iworkforGM
  7. I believe the tires are q rated which is 99 mph speed rating. The top speed is set at 1 mph below. #iworkforGM
  8. Transparent trailer will not work on fifth wheel or GN. The system will not calibrate. If you have a conventional trailer over the maximum length around 33 ft (10 meters), set your dimension 1 to the maximum. Transparent will work if you fake the actual length. Some of the images may not be ideal but, most people won't know the difference. Most people have issues with the dimension from center of ball to front of the trailer. This is dimension 5 or 6. I can't remember for sure. You need to measure this if the trailer had a flat front. So if trailer is rounded or pointed, don't measure to point closest to truck. Measure to where the trailer box ends. #iworkforGM
  9. I don't think you can level without proper rebound travel without control arm or frame modifications. There is a service rebound stop that would need to be modified or you will never get enough rebound travel.
  10. Some of their support is or their support is doing union jobs to keep things rolling. #iworkforGM
  11. 6.6L gas is running 11.5" ring gear for 2020. #iworkforGM
  12. I would recommend trying to see if your SD card is unlocked. Power off vehicle, open and close drivers door, and let truck go to sleep (wait until green monster light is out). Open center console, remove SD, look at SD card and there is a gray slider on left side of SD card, make sure that is in up position. Reinstall SD and start the vehicle, accept all the messages and see if any return after a few key cycles. #iworkforGM
  13. Does it come back after you accept the conditions during the next key cycle? #iworkforGM
  14. The speed limiter is due to your tire speed rating.
