“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. …”
