2019 T1 Silverado 4Cyl Engine Problems

MDSilveradoGuy · August 22, 2019

To each his own. One could bring up 5.3 piston slap into your argument.

Lines like "Every time I have driven a 4 cylinder car with a few thousand miles on it.. they rattle and vibrate and sound like heck" are ridiculous.

"Nope."

The ignorance of armchair reviewers never ceases to crack me up.

I know my 2.0 LNF 4 cylinder leaves many V8 owners thinking WTF just happened...

You can have your 4 cylinders. I dont care how much power it makes... or feels like a V8. The sound of 4 cylinder is is terrible IMO. I hear ecoboost V6 trucks running around with aftermarket exhausts and they even sound out of place. 4 cylinder.... nope. Every time I have driven a 4 cylinder car with a few thousand miles on it.. they rattle and vibrate and sound like heck.

Nope. Hahah.

The 4-cylinder in my car sounds amazing.

Nope. I love the sound and so do all my friends who've ridden with me. It's naturally aspirated, though.

You have to love how this thread has digressed into a "I would never have an I4 in a truck" thread. Almost no one has ACTUALLY answered the OP's question about whether or not anyone else has seen a problem with the I4.

Well, except for the guy with the buyback. Sorry Dude, Chevy screwed you. But, they really don't seem to care.

Amazing how people have somehow lost the ability to stay on topic and choose once again to express their opinion of what engine "should be in a real truck".

+1 on the being off topic. Unfortunately every thread about it gets dragged down the same hole by ignorance.

I will say this about my case - I gave them ample opportunity, I told them I just wanted it fixed right (not to have a 1 month old truck with a hacked up harness), they refused. They ran themselves out of time, I asked for them to replace or buy back the truck and they declined - in spite of the letter of the law being on my side. I sued - and could have forced a buyback, however in MD the manufacturer can keep up to 15% of the MSRP back to cover costs. We went back and forth and I ended up getting enough of a settlement that I can walk away from this truck in December/January when the diesel GC comes out and not lose any money. They screwed me up front, but I feel like I won in the end.

Every 2-3 years I buy myself a new GM truck, and in the past 3 years I've bought a Colorado and 2 Cruzes (1 for mom, 1 for us). Because of one smarmy engineer, GM lost quite a bit of revenue from this 1 customer. Granted it is a drop of mist in a bucket but it is something.

To the OP's point - if GM will replace it with the later harness (which has an updated part number), I would bet it would solve all of the issues. At the beginning of my saga, the part number was the same - and during this fiasco it changed, but GM wouldn't reverse course and put the proper part in.

This is because they no longer care about their customers. Though, I am not sure they ever did.

All that matters to them is profit. Nothing else.

Sorry for contributing to the off topic-ness. Can't remember if I said it in this thread or another one but, if I were going to buy a brand new engine like the 2.7T, I'd give them 2 or 3 years to work out all the kinks. I'm looking at a 5.3 with DFM and I'm still waiting until 2020.

I took a risk in doing it. I have zero concerns with the durability of the engine itself, personally. It's about the most overbuilt thing I have seen - it's the stupid accessories/electrical that make me cringe. Well, that and the horrid transmission that I have grown to hate.

Per your earlier comment, looks like they've come up with a redesign for that harness, so others should be able to have confidence they can buy a 2.7T and not encounter that same issue. It's just too bad GM wouldn't fix it right for you.

The other reason I'm (now) waiting for 2020 instead of letting me dealership push me into a late build 2019 is so I can get the 10 speed. Maybe they'll pair that transmission to the 2.7 eventually too.

Ha. Everytime I have driven a 4 cylinder this has been the case. Seems to not be an armchair "review". So say what you want, doesn't bother me.

AlljackedupZ71 · August 23, 2019

BUT, since we have off topic replies here ( guilty ) Sorry about the issue you had.... hope that it does not become a large issue and GM gets it fixed. I agree... I would not want my harness lengthened either. Just asking for problem possibilities down the road, 100% possible.

*shrug* Your ignorance is your bliss.

You can't compare the NVH, power profile or drivability of a large bore, long stroke 4 cylinder with a 5,600RPM redline to another 4 cylinder of dissimilar specification.

Again, what I do know. I only have 2 engineering degrees, a background in automotive engineering, have been a member of the Society of Automotive engineers for 20 years. Oh, and I actually own the engine...

Sounds like an armchair review to me.
