My 2011 Hyundai Santa Fe began to drive rough on the freeway, slight tugging, rattling sound under the hood and would not accelerate above 60mph, check engine and oil light came on. I exited the freeway and it stalled at red light. Started it up and then stalled 3 more times at every red light on the way home. I added oil and made service appt. Brought in for service died once on the way and again at the service center but did not start back up. Mechanic said engine failed due to crank shaft spun bearing. Sensors did not appear in advance sensors appeared too late causing damage to engine. My car is only 7 years bought brand new out of show room no previous major issues. Multiple complaints on line showing same problem with others. Unacceptable and dangerous.
Engine noise at cold start. When starting the vehicle after the car has sat for over an hour, a loud rattle noise is heard for 3-5 seconds. The noise is coming from oil starvation. I have been quoted that is a timing chain and guide issue. Several people online are experiencing the same problem.
