2020 Corvette C8 Has A Small Known Oil Leak Issue

Nothing major, but there may be a TSB about it soon

As reported by CorvetteBlogger, a handful of 2020 Corvette C8’s have had small oil spots appear under them after break in.

The owner of the Arctic White C8 in the article noticed one morning that a small oil spot had formed under his engine. He posted the picture, attached below, to It was suggested that he head to his dealer to have it looked at.

The response he received was that there was a hydraulic transmission mount that had a leaky seal. He also mentioned that the service advisor told him that a handful had been reported, and that a TSB was likely coming.

Thankfully, as it seems to be a known problem, they overnighted the replacement seal and had him on his way again within 24 hours.

Seeing as no more new 2020 Corvette C8’s will be made, it’s important that any owners report even the smallest issue to their dealers. This way, the Corvette team at GM can create TSB’s, fix the issue in future model years, and generally improve the manufacturing process.

Approximately 2,700 Corvette C8’s made it out of Bowling Green before GM shut down the factories due to the coronavirus pandemic.

    This is probably not true, although it all depends on when the plant reopens. GM has certainly not said there will be no more 2020s. At the moment, there are multiple ones sitting on the line, which will certainly be completed. And there are multiple other orders at 3400, which means all the parts needed to build them are in the plan. They will almost certainly be built, too. How many after that even GM doesn’t know yet.

    1. Bob,

      As far as GM has stated, they stopped taking orders for 2020 Corvette C8’s in mid-March, I think, and by then all of the allotted build slots were filled anyways. They had planned to continue on, but they cut off the orders and even refunded some people (or offered to have their orders become 2021 orders) because GM is now focused on providing healthcare equipment. While it wouldn’t be a stretch to get the factories running again, GM estimated that it would be August or September before full, 100% production would start again, meaning the end of the 2020 model year. That is what I meant by saying no more 2020 C8’s will be made. There may be more made *in* 2020, but they’ll more than likely be 2021 model year cars
