Our car quit on us last week. Not a push button start. My wife was driving and making a right turn into the driveway when it just died. Good thing this didn't happen turning into traffic or something. I took it to the dealer the next day and they couldn't find anything wrong of course. The tech did have the nerve to tell me that my oil was low and that probably caused it to turn off.
I'm pretty meticulous on maintenance of all my vehicles, and I keep a regular check on my oil as well as other fluids and such. I'm no mechanic, but I've never heard of that happening. If my oil was that low, I would have gotten an oil light I'm sure. He showed me the dipstick and it was off of the full line, but not even half way. I then asked if I possibly had a leak or if my vehicle was burning too much oil. (I knew it wasn't leaking, just wanted to see what he would do) He checked and found no oil under the vehicle, drops, leaks, etc. I told him that my oil was fine and was changed on a regular schedule. When he found out I changed my own oil, he logged it in the service receipt as, "Found out that customer changes own oil and oil was low. Customer refused oil service and stated he would do it. Unable to replicate engine cut off." I was coming up on 10k miles as of last week and was due for an oil change, so it's all changed and topped off with Penzoil Ultra synth 5w-20, OEM kia/hyundai filter. I'll keep you all informed if this happens again. Oh yeah, no aftermarket HID's or anything like that. (Though I really want some!)
