Wow, must be common, if they have a harness in stock. Hopefully it’ll be something simple, like a wheel speed sensor… 10 minute diagnosis, 15 minutes to fix.

I turned white when the GF said she drove the Caravan to the dealership on the freeway… in limp mode. (I was smart enough to nod and keep quiet.)

I would have screamed at my wife for a stunt like that, which in turn would provoke her to stop speaking to me. One could only hope.

lol Yeah, but it was only a car and she did stuff like that. A  
defective oil filter blew off after leaving the drive. She saw the  
light and “hurried” to drive it home… going another 16 blocks.  
Whatcha gonna do?

I had a software update about a month ago, it is suppose to catch any engine issues before they actually happen. It did in mine, I’ve been told it seems to be the knocksensor harness that went bad. The Hyundai dealership said that they had one in stock , fingers crossed…
