NHTSA Complaint #11526676 — 2014 HYUNDAI ACCENT

On 02/18/2023 at approximately 5pm, my family was driving on the highway, when unexpectedly, my check engine starts flashing and there is a noticeable decrease in acceleration and my vehicle feels rough/jerking as I head to the nearest exit. My spouse checks the vehicle and believes it is a spark plug/coil issue and we head to the nearest auto parts. The store rep is able to confirm engine misfire on all 4 cylinders, which does seem to indicate that spark plugs/coils should be replaced. We replace the plugs and coils, yet the replacement does not correct the problem. On 02/21/2023, I am able to have a certified mechanic diagnose my vehicle and he performs a compression test and confirms that 3 cylinders are at slightly lower PSI, and the 4th is at 0 PSI. Unknown to me, this means my engine needs to be replaced. The mechanic provides additional information that there are known issues with Hyundai engines and recommends I contact dealer, as he has also had a number of Hyundai owners with the same issue. I did further research and I discovered that my specific vehicle is not included in any current recalls. Yet I also discovered that there is an open Class Action lawsuit to expand the recall, which appears to include the engine in my vehicle. I did contact the Hyundai consumer affairs on 02/21/2023 and I am directed to contact my nearest Hyundai service center. I contacted the Hyundai dealership in Auburn, WA yet after my initial contact the representative fails to return my messages or follow-up. As this appears to be an ongoing issue with certain Hyundai vehicles, I want to make sure that there is a record of this incident for your review. The one ongoing issue I can confirm is that my vehicle appeared to burn oil. Although, it was inconvenient, I was able to get top offs at Jiffy Lube.
