Yes, it sounds crazy, but that is not too unrealistic. Better learn to do things yourself. Or find a local shop you really trust.I was told by dealer that my car need water pump & timing belt to replaced, the estimate i got - $2000 (include - parts, tax & labor).
What is the reasonable price for the replacement on Acura 2012 model & car milage is 75K.
The risk of going beyond the recommended interval (which you have already done, at 10 years) is that the chances increase of the timing belt failing (breaking). If that happens, it jumps the timing (google it) and you will probably need to replace or rebuild the engine in your car, which will cost much, much more than it costs to change the timing belt (and water pump) while it is still intact. So do it now. Shop around for prices; in addition to the dealer estimate, you can ask friends for recommendations for a good independent mechanic, which will probably cost less (as noted above by AcuraAddicted).The normal interval is 7 years or 105,000 miles for the timing belt change +/- water pump plus coolant change (serpentine belt kit, spark plugs, oil change, coolant, valve adjustment). It was around $1600 when I did my 11 MDX back in 2018 for the same service. Some folks have gone 10-12 years or 125,000 to 150,000 miles without any issues; but, do so at your own risk.
