“I was driving on interstate 15 northbound when I felt the rear end of my car slip. I was traveling at approximately 70 mpg in 5th gear on a 68 degree evening. I looked in my rear view mirror and saw smoke / steam coming out of the engine compartment. I pulled over as soon as I could, which was approximately 1 minute later. This is exactly what happened in NHTSA action pe13009.”

“I was cruising with the family at 65mph and heard my belts squeel and then stop after 2 or 3 seconds. About 20 seconds later a low coolant light came on and my temp light was blinking. Temp was only around 195 to 205, pretty far from the red. I immediatly pulled over and shut it down. There was a lot of coolant leaking, a large trail followed me off the interstate.”

“I was driving my vehicle down the highway while accelerating when I felt the car squirm and noticed a large cloud of smoke billowing from the rear of the vehicle. I pulled over and identified the issue as a catastrophic coolant leak from the engine area (rear) of the vehicle. I had the vehicle transported home and then to a repair shop where they identified the problem as a coolant line that became separated from the engine block. …”

“While driving home from work in december 2015, on a local road near my home, the engine began emitting a large steam cloud behind the vehicle and the coolant level light appeared. I pulled over and there was a major coolant leak behind the car. I had the car taken to a shop, and they identified the issues as one of the coolant pipes had separated from the engine and dumped all of the coolant on the road. In the attached image you can see the separated coolant pipe from the engine towards the back of the picture. …”

“Driving on private road and a radiator hose (in front of car) came off causing immediate and rapid purging of coolant on to all 4 tires and me spinning off of the road. Fortunately only into the grass on side of road. Car was flat bedded to mechanic for repairs. Spent several hundred dollars on repairs. Have since spent thousands on additional preventative measures due to mechanics alerting me that the hoses in the rear will let go and cause coolant loss. Had to pay for engine removal and welding of lines for my safety. Costs was well over $3000.”
