our car eats a ton of oil and the piston rings failed, we owe a lot on it and I'm told there is no help for this issue even though there used to be because we are outside the guidelines in terms of mileage and purchase date. our car has 156k its a 2012 MDX. VIN [XXX] . Just checking with everyone everywhere to make sure I've exhausted all resources as it will take 13,000 to fix and we owe 12,000.

ACURA MDX 2012 - PERSISTENT SLOW START OF THE ENGINE; ENGINE IS STRAINING TO TURN OVER/START. I HAVE REPLACED THE BATTERY 4 TIMES, CHECKED ALL POSSIBLE PROBLEMS (STARTER, SPARK PLUGS ETC.) BUT SAME RANDOM, PERIODIC PROBLEM OF THE ENGINE STRUGGLING TO START. RELATED PROBLEM: FUEL TANK APPEARS TO BE SOMEWHAT LOOSE; WHEN I BUY GASOLINE, I CAN SEE THE GAS TANK MOVE. IN ADDITION, IT IS DIFFICULT TO FILL UP THE CAR WITH GAS; THE GAS PUMP CUTS OFF BEFORE THE GAS TANK IS TO THE "FULL" LEVEL. MY GUT TELLS ME THAT THESE 2 PROBLEMS ARE SOMEHOW AFFECTING MY CAR STARTING. MY CAR HAS ONLY 51,000 MILES ON IT. I TAKE GOOD CARE/MAINTAIN IT. I HAVE READ OTHERS COMPLAINING ABOUT THE SAME PROBLEM!!! ACURA SHOULD FIX THIS! TOO EXPENSIVE OF A CAR; WHERE IS THE QUALITY??? THIS IS AN ONGOING PROBLEM OF MY 2012 ACURA MDX . PLEASE HELP.
