Does the 2015 Acura RDX have a timing belt or chain?

The 3.5L V6 engine of the 2015 Acura RDX is driven by a timing belt, that Acura recommends to replace every 75,000 to 100,000 miles. This is recommended, primarily, to combat routine wear and tear; if not for a regular swap, You run significant risk of Your timing belt failing. At highway speeds, this can lead to catastrophic injury, or even potentially loss of life. Contrast this to timing chains, which most automotive experts believe are "better" over the long term -- they're typically good for 250,000 to 300,000 miles, or the lifetime of the vehicle. However, You do have one advantage; the cost of replacement is significantly lower. If a timing chain fails, You may be looking at a repair bill upwards of $3,000, not counting any damage it does to the engine in the process.
