    Had my first hiccup, and it's little disconcerting.

    Usually about every two weeks I take my car through a car wash and I have to put the car in N-no big deal, no messages.

    This go-around as I was nearing the end of the wash, the Master Warning and the traction battery lights gets thrown, with the message on the display saying I should put the car in Park. Well, naturally you can't do that inside this car wash, so I waited until after I exited and checked the charge display: one purple bar.

    So I hit the freeway and within 5 minutes I go all the way up to all Green. So I go from one bar to almost 8 bars in under 5 minutes?

    I find this rather odd that all of a sudden I get this behavior.

    Here's my question: when this happens, does the car store a DTC code?

    I'll watch the charge level when I get back in the car.

    Did you have the A/C on and/or the headlights while going through the car wash? I think that the only problem is that the car needed to recharge the traction battery because the SOC had dropped to 40% and it couldn't because you were in N while going through the car wash. I doubt that you set a DTC, but it is possible since you got the Triangle of Death (TOD).

    Another way to get the TOD is to try to shift to D while the driver's door is open. The car does not like this behavior and will let you know promptly.

    Yeah, the A/C was on, but I've had the AC running before in near-identical conditions.

    I just popped down and checked the battery level, and its still green, so maybe this is an outlier.

    A/C takes a lot of energy - kiloWatts of energy. It can run the battery down pretty quickly.

    Hi Rahalco,

    So, you know what the SOC of the battery was before and after the car wash in both cases? This would take a scan gauge, as the bars on the MFD are pretty loose.

    I just may get a ScanGague after this episode.
