Engine Knocking Noise problems of the 2012 Hyundai Elantra

The engine started making a significant knocking sound , the vehicle only has 111000 miles on it, and the repair quotes are $6,500 which is almost what the vehicle was worth.

My 2012 Hyundai Elantra started making a ticking/ knocking noise in the engine. I googled the problem and found that many people were having the same issue. It was a missed step when building the engine. The noise is called piston slap. It's happening to a lot of Hyundai's from 2011-2016 Elantra and sonatas. Hyundai didn't do a recall because they don't want to foot the cost of replacing the engines. I took my car to Hyundai of south brunswick NJ on 7/3/19 no one called me until 7/9/19 I called everyday 3-4 times a day and kept being transfered to leave voice mails, I left messages and no one called me back. On 7/9/19 I was called and told it would cost me 6,766. 00 to replace my engine. I believe Hyundai should be responsible for the engine when they're aware of this issue and have not done a recall. The problem happened just starting the car one morning and the noise got louder each day.

I have 2012 Hyundai Elantra GLS with 1. 8 l dohc engine. When cold started, the engine produces ticking/knocking noise which quiets down after running for 15 minutes. But, I observed that it is getting louder and louder and the noise is also not getting reduced as it used to be. I went to northtown Hyundai and they found metal shavings in the oil pan. Hyundai refused to replace the engine for free even though they very well know that it is a manufacturing defect due to bad piston coating. The engine power has highly reduced and I am afraid that it might blow in the middle of the highway. I have attached the Hyundai canada bulletin where they acknowledge the manufacturing problem. But, Hyundai USA is not doing anything with this problem.

My steering is loose and the wheel clunks and rattles. Sometimes it feels like the steering wheel will come right off. I can hit the slightest bump and it will rattle and shake like I ran over a huge pot hole. Also, when I'm driving the car will suddenly slow down and whine like I hit the brakes even when I didn't. I was almost rear-ended when I hit the gas but the car decided it wanted to suddenly slow down a few seconds later. There is something terribly wrong here. The engine is also making a ticking/knocking noise when warming up. This happens daily.

When the weather got cold the engine started making a knocking noise. Took it to the mechanic and he said the block would need to be replaced and to contact Hyundai since this seems to be a common problem with the 2012 Elantra. Fyi: the check engine light never has come on for this problem.

I have an issue with a 2012 Hyundai Elantra. It currently has 84,585 miles and I purchased it used from a dealership at 48,484 miles. It was inspected by a Hyundai service department in August of this year after making a knocking noise and stalling continually. It was diagnosed by the Hyundai service department with the same exact issue the sonata has which is covered in the class action suit, but our dealers request for a new short block was denied by Hyundai. There are metal shavings in the oil valve, and also in the oil pan caused by shearing from the crankshaft. There appear to be others with the same crankshaft issue that own Elantra models as well. Please see above attachments. My concern is that the same faulty deburring process that was used on the sonata's crank shaft may have also been used on certain Elantra's during the same timeframe. I also have receipts of all of my oil changes. If there is any information that is public knowledge about this deburring process that might have been used on other engine models or if you have any suggestions on how to proceed, I would appreciate it.
