Hydraulic tensioner failing resulting in timing slip and catastrophic engine failure. Our car had stopped working while travelling on a residential neighbourhood, and needed a tow to the dealership. Upon investigation, we found out that the timing belt tensioner failed, likely due to lack of oil pressure. There was oil in the engine at the time set at the correct level. We later found out that this similar motor on other models has had a large recall. Pluggage could have led to lack of oil pressure causing it to fail. Luckily no other damage occured during this incident but this could have potentially high consequences if travelling on the freeway. Hyundai has shown no support or recognition in this issue so far and it should be reported.
