Peace of mind

Has anyone had difficulty getting GM to replace a failed oil pump? a new thread was started with a fellow member getting pushback regarding oil pump replacement. Has GM said they would not honor warranty due to oil filter not being applied correctly or the car being tracked?

I mainly want to understand if the date range is really the gating factor or if no matter what it’s all 2017/2018 cars.

I looked at the poll results and while I recognize that not all owners are part of this forum, the numbers seem rather low for reported failures.

I was never on the bandwagon to get my pump replaced and thought everyone was crazy but after a few years I’ve changed my mind because I love this car so much. Mine is a late model ZLE built the end of 6/18. I’ve decided I’m going with a Kaytech. My extended warranty is done this October so I’ll have it done before then. You can’t get a platinum extended warranty any longer if you’re past the standard bumper to bumper if it’s through GM. What else should be done at the same time if I’m not really looking to add horsepower?

I had a Katech put in at the dealer. My build date is 5/18, so I was worried. Make sure they check the cam chain tensioner spring. Some are slightly defective (cut too short) somehow.

I'm very glad I had the new pump installed. I never worry about being stranded or destroying my engine.

Pauly, are you going to a Chevy dealer for the work?

I’m actually thinking of going to a local speed shop. Florida High performance. They have a great reputation and think the owner is a great guy. I don’t think I’m wanting to add horsepower, I don’t really race my car and I’m wanting reliability more than anything. I’ll keep this car until I can’t drive a 3 pedal car anymore. Unless it’s absolutely ridiculous to do this and not add some power. I actually also don’t want to spend a ton of money either as I have a OBS truck that also needs a few projects this year and would like to do both.

Pauly, I am also looking for reliability. I was thinking of maybe a strengthened cam and chain. I’m having a tough time finding a reputable shop or dealership to do the work in the Baltimore area.

We are pretty lucky here is Florida. We have a few shops that are very capable. I’m wouldn’t be opposed to a cam also.

My 2017 oil pump failed in 2020, GM denied the warranty , started litigation in early 2020, finally signed a hefty settlement yesterday after 4 years … these companies that know they have a defective product are banking on folks not having the time or energy to fight them in court and be without a car for years … usually they are right , not in my case

Since 2017/2018, they have had over 9 revisions of the oil pump , the most recent versions are stronger than the originals, but still weak. Beat of luck to anyone still dealing with this … I miss my ZL1, but moved onto a c8 stingray and now C8 Z06, so all’s well that ends well

Here's to hoping the DCT in the C8 is flawless . It's a Tremec, so there's actually a chance it's robust.

The revised pumps after 2018 are not weak, they aren't built like a Katech but they still hold up just fine in stock cars and even FBO cars without any issues. If you're going to go into the block though for any reason, it just makes sense to upgrade to the Katech pump since its nearly bulletproof at any HP level.

Several revisions of those DCTs already too. I owned a 2020 Stingray, I never had any issues but only had the car for a year. I now currently own a 2023 Z06, no issues so far, but only 2300 miles on the odometer.

Congratulations. I'm glad you went through with this. Would your lawyer consider a class action for those that own these cars with weak oil pumps?
