Engine recall I was driving home from work and suddenly loud ticking sounds starting coming from the engine. Then the power almost went to nothing and the car started slowly down (as if the car had been turned off (it was still on). The check engine light came on and the ticking sound got louder. I was able to safely drive off without any accidents. I got home and called several machanics to see if anyone could come by and see what's going on as I didn't feel safe to drive the car. Today a mechanic came and said the following: check engine light on. Loud valve train noises and faint knocking can be heard at idle. Dead misfire on one cylinder. Noise is mechanical. One dtc returned (po365 - can sensor b ckt malfunction). Per mechanic - strongly suspect engine is in early stages of common failure. Inquire w/mfg engine recall. It is showing same symptoms as previous year recall for sonata hybrids and engine failures. There is low of power and loud ticking noises from the engine.

While driving home, I heard a muffled knocking noise coming from engine when accelerating. At the next traffic light, I waited for the light to change, and when I started moving I realized the engine did not start from the hybrid. As I dangerously maneuvered the car across the right lane, I was able to pull over to a safe spot and the warning chime came on saying I had low voltage in hybrid battery. Had car towed home and then to hyudai dealer. They notified me that the engine was seized due to poor maintenance, which was ridiculous. Oil has always been changed by me or a regular garage. After viewing other comments by people who had the same exact problem I realized that this was apparently an ongoing problem with the sonata hybrid engine. Still trying to get dealer to replace engine.

Right after I started my vehicle the engine starting making an unusual sound the other day. The noise gets worse when driving. I was told by a mechanic that the engine has knocking noise coming from it. I was told it probably needs and engine. I took it to the dealer and was advised that because it was a hybrid gas/electric engine it was not covered by the recall. I have seen several hundred people making this same complaint about their hybrids not just the regular 2.0 and 2.4 gas engines.
