2012 Hyundai Santa FE Engine cooling Problems

“Was traveling on interstate at 70 MPH. Exited and slowed to about 35 MPH, at which time the engine shut down. Engine started right back up and ran ok rest of way home. The next day when driving up a hill, engine began to knock and check engine light came on. I continued on to an autozone where I had it checked with a code reader. Code retrieved was p0014 which is b camshaft timing over-advanced or system performance bank 1. Removed valve cover and front cover and inspected the camshaft and timing components. …”

“On thursday mar 22 2012 I was driving my Hyundai Santa Fe se awd with 2400 miles on it in two way down hill road with a speed of 20 to 25 miles per hour than all of sudden without any warning or any sign the car just die on me I tried to turn it back on it did turn on so next day I took it to Hyundai delear in san jose california theey checked it and said they couldn't find nothing wrong with so I am kind of concern about my safety and my family if this does happen again.”

“1st of many total engine de-powerments happened at a stop sign, going approx.15 MPH. I had filled the gas tank and at the first stop sign I came to, the engine check light came on; and it died, powerless. I coasted to my destination (less than a block away) and called my service rep at danbury Hyundai (ct). She told me it was due to an incorrect gas cap replacement, to undo the gas cap and start the car. It worked. After the first episode, this absolute powering down of everything, brake, steering, control; happened so often, it became routine. …”

“This incident has happened 3 times so far. While driving I start to reduce speed. The speed gets down to about 20-25 MPH and the vehicle completely loses all power. It just shuts down in the middle of driving. There is no power steering or anything. I turn the ignition to start the car again and it starts no problem. I may not have the problem again for another month or so. This is a very dangerous and scary situation. I pray to god that it doesn't happen while I'm traveling down the highway. I asked Hyundai about it and they didn't seem to be too concerned. …”
