NHTSA complaint #11244556, filed 2019-08, 180,000 miles“On startup when cold, engine makes knocking or tapping noise. Noise goes away after +/- 30 seconds. I'm told it's a timing chain tensioner, a known problem in these 3.3 v-6 engines, but Hyundai will not recall them. The reason, I'm told, is that the engine must almost be completely removed from the car for repair.”
