2020 oil pump failure
Hi guys,
I saw this topic and share… maybe the owner is on this forum… I thought a lot of us supposed that it was only a 2017-2018 problem… |

Just because a 2020 has an oil pump failure doesn't mean it's a problem like it was in 2017-2018. There will always be some defects or failures in ANY year, it's when it's an unusually high percentage relative to unit sales that it becomes an issue. Overwhelmingly, 2017 and 2018 are typically reported with this issue, that does not mean there will not be a small number in 2019, 2020, 2021, 2022, etc. that won't have a defect.

I think we can never completely understand the extent of the problem unless we have exact numbers from GM. We have some idea, but our population is limited to those that use this website. The issue is probably more widespread. I wish GM would go further than the TSB regarding the spring. If other models used the same pump and there was a defect, it’s likely they are having failures not reported here.

I've read and read on these oil pump failures and warm up the machine completely each time I get in.

Hi all,
This issue was the biggest reason I sold my '18 ZLE. I even had a really great 120K 10 year B to B extended warranty, but I did not like the stress feeling all the time that a fun day driving to the mountains could end up in a blown oil pump, leaving me stranded. The new '22 ZLE has much better oil pressure and seems to be running as strong as my '18 did. I even used the newer 0W 40 Mobile 1 in the "18, but it still never had as good oil pressure as the new '22. I don't track my cars, and they always got early fluid break in changes and regular oil changes at no more than 4k miles. It is true that owners will never know what, if any, changes GM and/or Melling did to these oil pumps. I pray my new '22 will not give me the same stress that the '18 did about the oil pressure/pump failure. It certainly is running at a much better (IMO) oil pressure than the '18 did. I didn't get the extended warranty this time, as I am planning on purchasing a 2025 ZO6....after we see how those motors hold up after a few years in service. I really love my ZLE and will enjoy it to the fullest until 2025. If it starts to act up before then, I will trade it and get something else. I bet someday in the future some GM exec will let it out that they knew about the oil pump issue but did nothing to actually fix it. It is most unfortunate that GM did such a great job on these ZL1's, but 'cheaped out' on fixing a super important part of such a high output engine. JMO, Take care, JJ

Very presumptuous. The data thus far doesn't support your theory.
