Now that I've driven the Infiniti M37 for a while, it's time to provide a list of its shortcomings. Before I opened this can of worms let me make something clear. Although these seven things really bother me, I still like the car. I don't have buyer’s remorse, because [my Cadillac developed an unsolvable problem]. Even though the Infiniti M37 isn’t perfect, I would be in a much worse situation if I still had the SRX.
I will say I expected more from the five-year newer Infiniti product in the technology department. There are a bunch of things that this car is missing that Cadillac has had in place for a decade. Let it be known that there are many positive aspects of my new used car.

Fuel, Motor Oil and Hyper Maintenance
I think the strongest part about this Infiniti M37 is the 3.7 L V-6 engines. Unfortunately, they coax 330 hp out of the engine by using premium fuel. I didn't find out about this issue until the papers were signed. I hate pulling up to the gas pump and paying $.60 more for fuel than I paid for my Cadillac. With that said, the Infiniti M37 gets about 6 miles per gallon more in the fuel economy department. So the expense of premium unleaded fuel is slightly mitigated between this car and my old one.
Another difference between the General Motors Corp. V-6 and [the Nissan V-6 motor] is the type of engine oil they use. To my surprise the 3.7 L recommends conventional grade motor oil in the 5W-30 weight. This means oil changes every three months or 3,000 miles as recommended in the owner's manual. The Cadillac had an engine oil life monitoring system and used Mobile One full synthetic
