Well, I will chime in with my own scary moments...
#1 Scary Moment (street driving): When I was living in Costa Rica, I was on my way to the office. I noticed a strange feel in the brake pedal, but just thought "I'll look into it during the weekend). Well, unknown to me, the reason for the strange pedal feel was that the link between the pedal and the booster had literally broken in 2, so you can imagine how scared I got when I drove into the office park with literally NO BRAKES AT ALL! I downshifted until I was going fairly slow, and then just rolled the Jeep up a small hill next to the parking lot entrance. Boy, that was a fun experience!
#2 Scary Moment (street driving): While living in Miami, I had replaced the hood hardware with some cheap Chinese ones, as the stockers were all rusted up. I did notice that at highway speed, the hood seemed to "dance in the wind" as my wife mentioned, but I figured between the 2 latches and the hood catch, it was not really a big deal. Well, apparently, I was wrong. One day, also on the way to the office, I went over some railroad tracks on the road, and next thing you know, the hood popped open (I was doing about 45 mph) and slams into the hardtop. I could not see a thing, but managed to keep my composure and stop on the shoulder of the road to close the hood back up. Needless to say, I bought stock hood latches at the stealership, and have not had any problems since...
#3 Scary Moment (wheeling): More than a problem with the Jeep, this one was almost caused by an interface problem (as in the interface between the seat and the pedals/steering wheel; a.k.a., the driver!). I was going down a steep ledge on a rainy day, and I was on 4L and riding the brakes to go as slow as possible. However, between the rain and the dirt surface, I found out the hard way that the wheels need not to be spinning for the Jeep to go down. Next thing I know, the Jeep starts to move sideways, and all I could think was "oh oh!". Fortunately, there was a small rock at the side that stopped me from rolling over, and allowed me to gain control once again.
#4 Scary Moment (wheeling): We were out in the middle of nowhere, my Jeep was broken (e-fan had died on me because of some wiring problems), and I was trying to get back to civilization; but to reduce the distance, we had to take a shortcut that went over some log bridges near the border between Costa Rica and Nicaragua (talk about being out in the boonies!). It was raining, and the bridge was all muddied up from the rains, so the bridge was EXTRA slick, and since the logs were not even leveled, the Jeep keep slipping and sliding all the way through. The bridge was about 45 feel (15 meters long), and about 30 feet (10 meters) high, with whitewater rushing below.
