NHTSA Complaint #11622352 — 2016 HYUNDAI SONATA

My 2016 Hyundai Sonata started using and leaking oil in August 2023 when it had about 129,000 miles and when you tried to go faster than 55 miles per hr. it would not accelerate. We feel there is a danger to drive it in traffic. We took it to the dealership in Pensacola, FL. They found a valve cover gasket had multiple leaks which they replaced. Found a code P1326 (whatever that means), Performed T3G campaign and followed a flow chart and BCT test passed. Don't know that any of this addressed the fact that the motor won't accelerate. Charged me $3,000 for something. Car ran okay for a while and started doing the same thing again. In June of 2024, took it to local mechanic who ran diagnostics and replaced a coil and plugs which cost another $600. It ran a little better until August 2024 and took it back to local mechanic who did another diagnostic and replaced 4 plugs and PCV valve for another $300. It's now November 2024 and the car won't accelerate over 55 mph and we can't use it to drive to work.
