The coolant line that supplies the rear cooling and heating unit developed a leak. After having the SUV checked out found that he supply line was rubbing against the SUV body and frame. Line was not put in properly. Patched line with rubber hose to stop leak and to protect from any more rubbing against frame.

I ran out of gas on expressway on way home from work while gauge showed 1/4 tank. This happened again months later with tank showing just under 1/4 tank. Gauge around the time of first incident started bouncing around off and on at any reading while SUV was running. It would go from empty to 1/2 a tank and bounce around back and forth eventually stopping at a random amount. The gauge would go to empty when it was full until it was driven enough that I was down to around 3/4 of a tank then it would give the correct reading until guessing around 1/4 of a tank when the incidents happened with me running out of gas. A few months later the gauge completely quit working and has yet to work since then. I started researching online about the gauge and found multiple incidents with same year and make and many people stating they paid over $700 to have repairs done and multiple people stating they had it fail again. Since reading those remarks I have yet to have it repaired and have had to keep track of my mileage so that I don't run out of fuel again.
