nothappy Posted April 10, 2015 Share Posted April 10, 2015 Has anyone had a MKZ shut down on them while driving? My daughter has had this happen a couple of times now. While driving, the dashboard lights flash and she loses power, she cant go more than 25mph. Had it into the dealer today and they said they have never heard of this and did not have an answer for us after $200 in diagnostics.

Had it into the dealer today and they said they have never heard of this and did not have an answer for us after $200 in diagnostics. Did the dealer mention anything about the coils/plugs, or the power control module? No error codes at all showed up from the diagnostics? Hope your mystery gets solved soon.

nothappy Posted April 10, 2015 Author Share Posted April 10, 2015 It failed 2 days ago, and the dealer said not codes were found in the system, they also drove it today for a long time with no error codes. Quote Link to comment Share on other sites More sharing options...
KenZ Posted April 11, 2015 Share Posted April 11, 2015 It failed 2 days ago, and the dealer said not codes were found in the system, they also drove it today for a long time with no error codes. Have not had a problem like this. I did have an issue with the nav system on an Acura a few years ago that they could not replicate at the dealer. It was very frustrating and I was getting no satisfaction. Finally, I realized that I could take a movie of the problem with my iPhone. Next time it happened, I took a movie of the nav screen and showed it to them. They requested a copy of the movie, a few days later, they had a fix.

4N1M4L Posted April 11, 2015 Share Posted April 11, 2015 Almost sounds like its derating for overheating. No codes sounds like replace the ecu. Quote Link to comment Share on other sites More sharing options...
07_MKZ_WV Posted April 13, 2015 Share Posted April 13, 2015 This exact thing happened to my 07 MKZ this weekend. However, i was drag racing my friend in his Infiniti G37. At 60 MPH and maybe 7000 rpm she shut off completely. I rolled safely to the next stop light, turned the key back, then forward to start again. She fired right up and has never had an issue since. Seemed off to me, I've not had it to a shop - but was sort of glad to see that it's happened to someone else. Quote Link to comment Share on other sites More sharing options...

There's a fueI shutoff/rev limiter. It probably shut off to protect itself. This scenario is not the same as described by the OP. That occurred under, presumably, normal driving conditions and was accompanied by flashing IP lights. Quote Link to comment Share on other sites More sharing options...
firstlincoln63 Posted June 17, 2016 Share Posted June 17, 2016 My 3 month old, 2015 had a similar failure. While leaving an ATM, loss all power, could only go about 5 miles per hour, but had a wrench warning light on the dash. I turned it off, open the door, and then started it up again. That process resets all the electronics. Drove it normally to the dealer who reloaded the computer's memory and told me it was a known problem. I just yesterday drove a loaner MKX (the suv model) and the exact same thing happened. Very scary and dangerous. Quote Link to comment Share on other sites More sharing options...

NHgirl Posted December 4, 2018 Share Posted December 4, 2018 (edited) Dealer couldn’t find anything after two days of having the car. He told me I have no options but to drive it and hope it happens more often to produce a code. So disappointed and actually nervous Edited December 4, 2018 by NHgirl Quote Link to comment Share on other sites More sharing options...
