2019 Kia Sorento: shudder or vibration when accelerating

Filed Jun 20, 2026 · Engine · CA

The engine failed and is now inoperable. The vehicle has been consuming excessive oil since I purchased it in 2022. I have all oil change records and top offs documented. In May 2026 the engine had a total failure, was making excessive noise, was shuddering and vibrating, blowing lots of smoke from the exhaust and then would not start. The check engine light came on. I towed it to Roseville Kia for diagnosis. Kia refused to honor the lifetime warranty under the class action lawsuit, claiming the engineer failure was due to a damaged exhaust valve. The did not complete the diagnosis. They did not follow the federal safety agency engine replacement flowchart past flowchart A because code p1326 was not present. However the flowchart specifies engine noise and failure to turn over qualify the technician to perform flowcharts B and C. Kia is refusing to complete the diagnosis and evaluate the rod bearings for damage, which would likely qualify the engine for replacement under warranty.
