NHTSA Complaint #11505297 — 2015 HYUNDAI ELANTRA

My vehicle is just over 80k miles and has received regular maintenance services. Inspection available upon request. My engine would rattle during idle, stopped at a light, and sounded as if the RPM were increasing. I would have to turn my car off then back on for it to stop. No engine or warning lights. As this became more frequent, I also noticed a very intense shaking coming from the front passenger side of the vehicle while driving on the highway. The shaking was most intense as the car accelerated from 2k-3k RPM. It felt like I could have lost control. On 11/29/22, my car was towed to a repair shop because the engine would stall when I started my car. After examination they recommended I take it to a Hyundai dealer, determined the engine may need replaced and informed me of other recalls from similar models. When the vehicle was brought to the Hyundai dealer, they stated they could not replicate the issue - the engine would start without stalling - but they also speculated my problem was from a loose cable, and attempted to send my car home with me the same day. It is important to note that the battery cable was examined and was connected prior to bringing it in to the dealer. My car is not under recall so my request was taken lightly, they stated I had no engine issues. I pressed for them to address the rattling of my vehicle, for which they then told me I had a leak in my front left axle. Axle was repaired and car brought home. My car drove for about 212 miles before it started stalling again with multiple attempts to start it. When I was able to successfully turn the engine over, I drove it back to the Hyundai dealer on 1/02/23. They found no codes but determined the crank sensor needed replaced. After replacement, they informed me my vehicle still “acted up” once, so they have held onto the vehicle for the past month, letting it sit and occasionally test driving it. Still no answer to this irregular issue.
