jwroch posted a topic in 2014-2019 Engine, Driveline, & ExhaustI have a 2014 Silverado LTZ, with a 5.3L engine. There is approximately 145,000 miles on the engine. I have a misfire on the #3 cylinder. I have replaced the induction coil on the #3 cylinder, but I still have a misfire on this cylinder. My mechanic says that the lobe on the camshaft is worn and the camshaft needs to be replaced. I would think that if the lobe on the camshaft is bad then other lobes would also be bad, a defective camshaft. Has anyone else had this problem? Does anyone have any suggestions as to what might be causing the misfire. Thank you in advance for any advise the you can provide. Julian.
5.3L vs 6.2L in 2018 Silverado
zettiefan posted a topic in 2014-2019 Engine, Driveline, & ExhaustHi 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!
