Coolant Leaking Problems of Nissan Murano

I am the 'second' owner. The vehicle was gifted to me by my son. It passed the autocheck vehicle history report. I received the vehicle 5/11/13. Failure mileage is approximate. When starting engine huge amount of white smoke exits the 2 exhaust pipes engulfing entire vehicle. This happened continually every time I started engine. Contacted Nissan consumer affairs directly & was referred to dealership. My son spoke directly with dealership service department. The required 30,000 maintenance was performed. After 1 week dealership recommend new engine. I was 6 months past the warranty date, but Nissan refused to honor it as I was a second owner. Per my son's instructions dealership removed spark plugs to soak tops of pistons. Let soak over night. Performed a leak down test to find all the cylinders with 60% or more leakage from rings and valves, removed oil & performed 2 engine flushes, cleaned all oil out of intake maniford, reinstalled plugs, changed oil again, performed multiple road tests. Preceding service included replacing engine air filter. Performing idle learning procedure. Fuel system serviced, cleaned fuel injectors & throttle body. Removed all build up from throttle chamber & plate. Performed fuel system service and 6 cyl tune up/6 22401-ew61c plug-sparks. Serviced complete coolant system. Serviced automatic transmission, exchanging fluids in case up to 6 quarts. Performed front & rear differential fluid exchange. Dealership kept vehicle 3-4 weeks, however problem still exists although intermittently.

1st issue:. . . . . . Coolant smell. Dealer said could not find (acknowledged smell). Topped off surge tank. Coolant still dropping over time. . . . . . ; reviewed: found coolant leak on passages side (fire wall side) mid engine above exhaust 9" inches. . . . . . Viewable from bottom of engine looking up between exhaust and frame line (light is required). . . . . . . Cannot see source. Will need bore scope to further review. . . . . . . . Plan to take back to dealer with info. . . . . . . Blue colored coolant is not staining area well. . . . . . Suggest: pressure check coolant system, this will force the coolant to drip while looking up. Sorry dealership I am a 3rd generation mechanic who works for the government. . . . . . . . . . . . . . . . . . . . . . . . 2nd issue:. . . . . . Transaxle fluid is leaking out of weep hole. Seal is suspected of failing. From bottom view look up at transaxle weep hole, with associated oil and dirt deposits from oil seepage. Will take back to dealership. . . . . . . . . . . Inspection: flash light looking under engine (center) 3' feet back any oil or dirt build up is a suspected leak (dirt sticks to oil). . . . . . Suspected down time 2 weeks for repairs. . . . . . . Failure to repair: I suspect and believe this might cause transaxle to fail possibly locking front wheel and loss of control issue to occur.

Vehicle was in shop for major (60k) maintenance. Inspections showed some leakage of coolant from top of engine, diagnosis confirmed as leaking head gaskets. Have pursued complaints with Nissan dealer and Nissan consumer affairs. This is a major defect requiring expensive repair if not corrected could lead to engine overheating and failure.

Faliure of coolant reserve tank. Noticed a leak under the car and at first it could not be traced. But on the last oil change a crack on the edge of the coolant tank was noticed. Dealership had this part readily available in stock, which leads me to believe that they are aware that there is a design flaw on this tank. The tank was not damaged or showing any signs of where and tear. The position of the crack leads me to conclude a design flaw.
