Good thought, I’ll take a look at the batteries. I don’t know how old the battery is on this car. It has always started just fine since we bought the car (about 3 months ago now) but on these computerized cars things can be weird.
A couple of other notes:
- When the Failsafe Engine Mode and Check Rear Lights indications come on, the cruise control stops working. The indicator light by the shifter goes off and it won’t work
- It’s been cold (below freezing) every time I drove it with these lights on until today. Today it was in the mid 50s (F, not C… so figure about 12-15C) and today I really noticed it being down on power from a stoplight. This makes me think the electric water pump for the intercoolers isn’t working
My first question: What exactly does “FAILSAFE ENGINE MODE” mean? I’m not getting a check engine light with this. Would it still throw a DTC?
Can this be triggered by an inop intercooler electric water pump (which I know are common failures) or, if this is triggered, will it turn off that intercooler electric water pump on its own?
And yes, when the “Check Rear Lights” is on (keep in mind: these ALWAYS go on together) I’ve confirmed all the rear lights work. So that also makes me wonder if there’s a computer/module that’s going out that somehow controls both those items (the rear light diagnostics and the electric water pump).
