1 Crankcase (pcv) problem

Failure Date: 08/23/2023

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.

2 Crankcase (pcv) problem

Failure Date: 08/26/2021

Problem is the engine is burning two quarts of oil every 1,000 miles. Was taking car in for oil change and check engine light went on. Service person said car was way down on oil which is why engine light went on. Said there was a problem with Hyundai engines and to take it to dealer. Dealer ettleson agent john cunniff confirm that there is a problem with that engine and said they would run an oil test. Oil was changed with new filter and told to come back in 1,000 miles. Returned to dealer after 1,000 miles and engine was down two quarts of oil, dealer topped off oil and said someone would contact me. I called several days later and john cunniff said that using two quarts of oil in 1,000 miles was within specs. He said to contact Hyundai customer service. I did with case # 19220125, and frances was case worker. Attempted to contact frances three times with negative results. I called and spoke with a cindy who stated case notes stated frances contacted ettleson and they said two quarts of in 1,000 miles is normal, complaint was closed. Research disclosed there is a problem with oil consumption in that engine, backed up by their and other mechanics. I have 69,000 miles on the vehicle and a 100,000 mile warranty. I have all maintenance files for the vehicle since I purchased it. I have complied with the dealers instructions and have had my pcv replaced, and just keep adding oil to keep my engine running. Please advise my options.
