NHTSA complaint #11566325

Owner complaint summary

On November 8, 2023 my check engine began flashing and my car lost Speed/Full power. I knew there was a knock sensor issue because I had this replaced in May of 2023 in order to comply with extended warranty services. I immediately pulled over to see if there was an identifiable issue. I was able to make it to a local orileys and they did a diagnostic check. It gave the p1326 code which I researched and found this to be the dreaded "needs a new engine code". I wasn't able to get an appointment until November 21st with a dealership. The one in my area wasn't taking anymore due to have over 100 vehicles with the same issue. My car has been at a dealership now since my November 21 st. It's extremely difficult to get a call from these people with any information. I called Hyundai and got a case manager, but that wasn't much help either. He said the dealership was very difficult for him to get in contact with as well. After numerous attempts and no returned calls or texts, I was finally asked for my maintenance records which I sent. I have all oil change records which showed the maintenance was done and in the correct manner and time frame. On January 10th I was told that my issue was not the rod bearing issue that is covered under warranty, but instead it was a piston slap in my engine and that Hyundai had agreed to pay for half of my engine replacement. My cost would be $3,200 plus they had already charged me $250.00 for a battery replacement. I feel this is Hyundais way of skirting around the warranty wording. The piston slap needs to be covered under their extended warranty. This is all related to their bad engines. There was a specific campaign focused on the p1326 code. I have been without my vehicle for 3 months now and I'm still making payments on an auto loan and paying insurance on a vehicle I can't use. The service manager told me that my car was still drivable, but it's NOT SAFE His exact words. Was notprovided a rental and told it's notcovered
