Sometimes 2010 Santa Fe will not start...there will be no sound at all and none of the usual dashboard light would come one, no sign of life whatsoever. Also, when this occurs, you will notice that the clock re-set back to the default time of 12:00am, as if the battery was disconnected for a moment. However, if I wait a bit, like 2-5 minutes, then it starts just fine. Also, I already had the vehicle computer checked for any recorded trouble codes...nothing was recorded.

- Cloud this be immobilizer or ignition issue, where one of these or both need to be replaced?
- If not, what else could this be?
- Also, could the reason for no trouble codes recorded in the computer, because these are also lost when this issue occurs?

Thank you in advance for any help.

Mechanic were working on changing out the AC line and everything stopped working. This happened yesterday after completing an AC job. Car was taken to a sister shop. On the way over car stopped.
The replacement I got lasted 5 months and went out. It also makes a noise when put on recirculate but stops after a few minutes. The blower motor they gave me from the warranty is getting hot very quick, is there a relay switch or something causing this to heat up? There is no noise when it's on vent but the motor still gets hot.
I have a 2010 Santa Fe with 115k mileage start randomly dieing on me took it in got the valves tightened and the Throttle control switch switched out, but when I got it back from the shop it died within a mile from the shop once I turned on my AC... not sure if this will effect my heater too or just the ac. Please help as the Repair shop is trying to say its so much more than that!

It drained the battery, and it runs when a charger is put on the SUV. No key in ignition. Brake relay switch was recently replaced (recall), so is it possible they cut or partially cut a wire?
