NHTSA Complaint #11456916 — 2020 CHEVROLET MALIBU

I need my pistons and rings replaced. My car only has 57,000 miles. My car has been diagnosed with excessive piston blowby from 2 different independent service centers. Both times I have been to Chevy to get it fixed under warranty, they’ve charged me $200 for diagnostics each time and told me it is my PCV valve that needs fixed. I had them fix my PCV valve and I still have excessive piston blowby. Chevy just wants to keep bringing my car back in for more diagnostics. I have spoken with GM customer service 2 times and somehow every single time I give them my VIN they hang up. My car is a 2020 with only 57,000 miles on it. There’s absolutely no reason why I should need all new pistons and rings and why Chevy service centers won’t just get it done! I have diagnostic reports, receipts, and videos of everything.
