What is the tapping noise in my engine?
Ticking, Tapping, Or Rattling From the Engine Often times, the noise is most noticeable on engines that use direct injection and is not a cause for concern.

If it is in good shape and inspection checks out, go for it. I’m not aware of any high mileage issues with the 2015 model but keep in mind 100k is near the leading edge. Most are driven 10-15k/yr so more like 60k. If it is in good shape and inspection checks out, go for it.
Why is my engine ticking while idling?
The engine’s cylinder head uses a series of lifters in order to open and close the valves. These lifters can get worn out over time, which inevitably causes a metal-on-metal ticking noise at idle and upon acceleration.
What is the lifter noise?
A car lifter refers to your car’s hydraulic valve lifter. It’s a small cylinder attached to your car’s hydraulic valve by a rod called a rocker arm. The system works well, except when it doesn’t. A phenomenon can occur called lifter tick, where the lifter itself makes an irritating ticking or tapping noise.
