I bought a 12' pop up trailer in the spring, one year after buying my 2011 Journey crew. Thought i had the tow prep package installed, but turned out it didn't have the wiring harness. I was assured by the dealer that it did have an Oil cooler, Tranny cooler (and power steering cooler) 'though. So just before i picked up my new trailer, i purchased the wiring harness for the journey, and had a hitch place install the harness and receiver. Once completed, it took some tweaking to get the brake controller to work properly, along with the pig tail connector. Seems the LED brake lights cause some problems for the connector etc. That all got worked out and we happily towed the trailer (dry weight of 3100 lbs) this summer about 6 times.
In the 2011, i have the EVIC, which allows me to monitor the tranny temp, coolant temp etc etc. The tranny ran at around 68ish degrees without towing, nearing 70 to 72 on the hottest days. While towing, temps ran around 76 and creeped up to nearly 80 at times, but always ran "in the green" and power seemed okay. (i've never towed anything before, so it was difficult for me to determine what was "normal" behaviour during towing).
Anyway, a week ago, i'm on the highway when suddenly the journey starts to sputter and cough, like it's running out of gas. Lasted for a minute or so and then stalled. Still had accessory power, but no power steering or brakes. Took it to my local dealer who determined that it blew a connecting rod. Hoping it's not related to towing,and pretty certain it can't be proven, but wondering if anyone else has had a similar problem whether towing or not? I hope it's just a bad part.
I've also had the battery problem twice in 16 months. the first time was the software upgrade programming issue, the second time (recently) they changed the battery out.
So far, I love my journey, but am very concerned over these issues.
