1 Crankcase (pcv) problem

Failure Date: 07/10/2025

I am writing to file a formal complaint against Hyundai motor America and the freehold Hyundai dealership located in new jersey, regarding the ongoing engine oil consumption issues in my Hyundai Sonata. I purchased a 2019 Hyundai Sonata and its now 90,000 miles, I began noticing extreme oil loss, far more than a quart per thousand miles, with no visible leaks, no smoke, and no warning lights. I brought the vehicle to freehold Hyundai for an evaluation, and they performed an oil consumption test, confirming the issue. They submitted a goodwill repair request to Hyundai corporate, which was denied solely on the basis that I am the second owner, and the powertrain warranty does not transfer. The dealership offered a $200 pcv valve replacement (a part that costs $6–$20), but even their staff said it likely won’t resolve the issue. Their proposed solution is a full engine replacement costing $8,000 or more, which I cannot afford. I believe this is part of a broader manufacturing defect, and Hyundai should take accountability for the engine failure, especially considering similar complaints from Sonata and elantra owners nationwide. Tsbs (technical service bulletins) have been issued on related issues. A car engine should not fail before 100,000 miles under normal use, regardless of ownership transfer. This issue has been the subject of TSB 20-01-004h, which addresses excessive oil consumption due to piston ring Hyundai’s refusal to provide any real assistance or remedy — and the dismissive conduct by dealership management — has left me feeling discriminated against, frustrated, and financially trapped. I request the bbb’s help in facilitating a fair resolution, either through: a warranty repair or subsidized engine repair coverage under goodwill or defect-related remedy reimbursement or alternative assistance please find all supporting documentation attached, including my Hyundai case number dealer correspondence, and oil test results.
