  1. Hello all, Thank you in advanced for checking this post out! I have a 2018 GMC Yukon 6.2L L86 10 Speed. Under harder acceleration there is a rattle noise that appears under the hood passenger side. This noise can be played around with by the amount of throttle you give or take. Letting off the throttle just a hair noise goes away, accel little more and comes back. While you hear the noise and keep same throttle position it will go away shortly as if the load on the motor isn't as high. Sounds like it could be the high pressure fuel pump engaging. Has anyone herd this, or know a little bit more incite on this topic what it could be? I have not taken it in for service, does not sound threatening, just noticeable. Thank you, Blake
  2. Hi everyone! This is my first post, but I have been faithfully lurking for the past 6 months racking my brain over our current SUV's issues. I am a born and raised Chevy girl as my dad retired out of GM in metro Detroit. That is pretty much all I have ever driven. However, I am at a loss at the moment with our latest experience with our 2017 Chevy Suburban 5.3L V8. We have had 3 fuel injectors replaced due to misfires, the entire fuel system replaced for a gas fume leak issue that took 2 months to resolve, the SUV shifts like crap which they claim is normal - overall we have lost trust in it and are getting rid of it ASAP. Previous to this one we had a 2010 GMC Yukon XL Denali with the 6.2L V8. We never had one issue with that engine and I regret so much not holding onto the Denali longer. I loved that truck. As much as I am hesitant to pull the trigger on a 2018 GM product, I am not impressed with the competition. Every manufacturer has its issues. GM and the dealer we have been working with have helped us to resolve this to the best of everyone's ability so I do not want to discredit that. My question to all of you who are much more mechanically savvy than myself, would you chalk this up to a fluke with the 5.3L or is that engine just not capable of having good drivability? My gut is saying go back to the 6.2L, but they too according to the forum have potential issues too even though they are not as common as the 5.3L. I don't mind paying out for tuning to prevent the issues we have faced as it seems that has been a fixed for quite a few on here. Also if it matters we are going to a full size pick up truck this time (and yes I already know about the Chevy shake). I just want a vehicle that is dependable. Thank you for your insight!
  3. Hello Thinking about purchasing a new GM truck. I am wondering if anyone is having any problems with their new 1/2 ton trucks. Is GM having any problems with the 6.2 Liter Eco Tec 3 engine or still having some troubles with the new 8L90E Transmission. Other troubles and their solutions would be intresting too. It would be nice to learn in advance what to expect, will it be a wonderful smooth ride. Should I expect a few fixable bumps along the way or am I entering a nightmare ride. Thanks in advance for your input. Success stories are certainly welcomed for a well rounded view.
