NHTSA Complaint #11715769 — 2017 HYUNDAI TUCSON

Purchased used via Carvana in Sept 2025, check engine light came on while driving it home indicating a pre-existing mechanical defect. We submitted the claim through Silver Rock (Carvana's warranty company) and brought to their approved mechanic. The recommended the following repairs, several that were denied by Carvana/SilverRock: spark plugs, alternator, serpentine belt, fuel injection service, electrical ignition coil. A month later check engine light illuminated again and through further diagnostics the mechanic found that 2 of the faulty spark plugs were an incorrect model/fit for our vehicle and reported that information which resulted in replacement being approved (a month after initial request). Fast forward to January 2026 we experienced the widely reported knocking noise while driving coming from the engine and had it towed. The damage is a thrown rod and damaged bearing, which is consistent with the current oil consumption litigation, requiring engine replacement. Our 2017 Tucson 1.6 L turbocharge is not included in the recall. Furthermore, Carfax report shows last oil change reported was 2023. Carvana confirms an oil change is part of their 150 point inspection before a sale, however unable to provide me with documentation and failed to report a record of the work to Carfax. There are many instances of negligence on Carvana's part from failure to provide record of maintenance, which is also failure to adhere to their standard policy, and declining recommended service directly from their approved mechanic, knowing that this vehicle could be impacted by the well known defects through Hyundai. We are requesting assistance with engine replacement meeting safety standards and ensuring consumer protection.
