2014-2018 5.3 fuel injectors

[ChevyBrad1500]

Why are so many 2014-18 5.3 fuel injectors going bad? Is it due to no changeable fuel filter? Are they just clogged? How can we prevent it? Sea foam?

How can you tell if they're going bad?

I would be interested in where you are finding the data to back up your claim.  If you are actually serious keep in mind that people who are not having any issues just keep it to themselves.  That's the problem with people these days, they take something posted on the internet as being factual and then parrot it.

Just judging by the crap I see day in and day out, I'd say it's GM trying to save a buck, as usual.

 

Those model years are still a few years away from showing up in my shop, and every year things get worse and worse. I can only imagine the fun we're gonna have with the current crop ...

My friend has a 2016 5.3 with 40,000 miles and 3 bad injectors. It's going to cost him $1,000. When I had my oil changed at the dealer, the service guy told me they are having a lot of injector problems in the 5.3 and 6.2. I have a friend with a 2014 5.3 that has had injectors replaced. I know 3 Escalades with 6.2's that have had injectors replaced. It's a common problem. These examples are local people and not posted on the internet.....that's where my info is coming from. I'm sure there are more people without problems than those with problems...I get that, but I was just wondering what I can do to prevent a future injector problem?

I read about this constantly from fellow techs across the nation. Was happening right out of the gate, too - I saw some with less than 1k miles having issues. GM more than likely wanted to keep a lid on that ...

 

These things are a PITA to replace, too. The connection is a one-time fitting - in other words, any time the fuel rail is taken apart, you get to buy a new one ... and GM smiles all the way to the bank.

 

The only real solution is to find and fix old, or wrecked vehicles - save them from the crusher, and get as many as possible back on the road. Only way things will change is if people stop buying these new ones, and demand quality. Sadly, too many can't be bothered ... which is why thing are the way they are in the world today ...
