My wife and I purchased our first commander (2010 sport 3.7l 4*4) monday evening, by tuesday evening we were rear-ended on the freeway while stopping for a traffic jam (thankfully no one was hurt). The other insurance company has stepped up to the plate and is covering the repairs. While talking to the body shop I noticed we were missing the rear (3rd) seatbelt cover and owners manual. Fortunately, the dealer has ordered these and will be given to us when they arrive. Additionally, when talking to the salesman prior to purchase, I noticed an opening where the transmission dipstick should be. I asked the salesman and he thought it was some sort of vent. After some inquiries I found out that there is supposed to be cap over (where the dipstick used to be) this access. I have no idea how long this has been exposed, could've been just prior to purchase during service or perhaps carelessly left off by the previous owner? I spoke with Jeep and they are now ordering a new cap for the transmission (tech dipstick) access. Not knowing how long its been off, should I see about having the transmission serviced to be on the safe side (approx 32000 mi)? According to the dealer we have 3.5 years remaining of the 5 year 100,000 power train warranty, but would certainly rather maintain what we have! Anyways, we love the Jeep, makes my 89 cherokee feel like a horse drawn carriage. Really looking forward to getting the commander back shortly; fortunately, it just needs a rear bumper and some significant exhaust repair after the accident. This thing held up incredibly well during the accident (I would expect no less from a vehicle that gets 15 mpg!
