That's a good video-as it explains clearly the mess you have. Its awful and I feel for you.
I took a quick look at the MDX forum but don't see any similar issues being reported on 2012s. Their engine is similar but larger capacity. Can't see anything on the Ody site either, their engine is similar to ours but not AWD which isn't the issue here.
1: Any anti theft or remote start device added to your car after the factory. If so remove and see if that makes a difference.
2: If just the Honda locking system, wonder if any ignition interlock can disable the fueling of the vehicle leading to no start.
Moving on since you do get a start sometimes suggesting any anti theft ECU is sort off ok.
3: Engine ECU. Have dealer swap out the ECU on a trial basis with another 2012 Touring. Any difference in starting performance? If yes, either the programming of the ECU is bad and it needs to be reflashed or the ECU is bad requiring replacement.
4: Does that make a difference? If yes great-if no moving on
5: Is water temperature sensor defective? If coolant is cold it should tell the ecu allowing it to increase fuel to the engine for cold start.
6: Is IAC defective-possible
7: Fuel line pressure ok or inadequate?
8: Defective fuel filter-blocked?
9: add to the list as necessary
My own take is that changes to improve MPG have adversely affected the starting ability of the car. What worked for the engineers in the Lab, doesn't work in the real world.
You would think this kind of thing would get noticed especially if the car refused to start at the end of the production line.
I had this happen 3 times in the past few weeks, both cold and normal temps. Here is the "response" I got from the dealer....
He said that Honda stands by the fact that this is normal for the 2012's.
He said I should just let it crank and that it can take up to 10 seconds to engage. It may be detecting high emmission levels caused by the ethanol in the gas that I use.
Not loving this!
