My engine was replaced under warranty due to the major theta engine recall, after 20k miles on the new engine its failing too, burning oil, smoking, making loud valve train noise on acceleration, and at time operates very sluggishly and strangely no engine codes ,almost like my engine code system was programmed to ignore these issues. My new replaced engine seems to be failing again and they don't care. I'm afraid this car will catastrophically fail or catch fire like I've been reading about. . Because its past the 12k warranty they are declining to fix,12k warranty really ???!! here's my concern, I am hearing many many ,many stories from others and even the dealer people that Hyundai is replacing the recall engines with bad faulty engines, some I've heard have received 3 engines. My dealer lied to me saying it was a pcv ,the pcv valve was replaced and my engine is still failing like the first engine. Please help, Hyundai is basically getting away with ignoring the recall settlement by replacing the engines with still known faulty engines !.
At 1st my car my consuming a lot of oil. I was going to get top off at my oil place every week. I tried to take it to my nearby Hyundai, they told me they wanted $350 to do a test. Then my car was not gasing the way it usually did. It was stalling, I had a burning smell coming from my engine. I took it to my mechanic and he replaced the O2 sensor, heating sensor, pcv valve, he did a transmission flush. It started to work ok, and I was driving with my disabled husband and our 4 year old daughter when the car engine went out on us on the highway. We got the car tow to our mechanic and its more problems then solutions . Its now the Cadillac converter, this car is extremely dangerous to drive. I have receipts of the repairs, towing and daily oil inputs.
