Will work for the 2016-2018 Maxima
Worked well and fit perfectly on my 2017 Maxima. It’s a slightly tighter fit than the OEM cap, but still a good fit. Can’t speak on it’s quality just yet but will update review if it ends up being low quality. BTW, there are a lot of reviews that don’t mention the type of vehicle they purchased a specific product for. If you’re reading this PLEASE mention your vehicle year and model in your review to help others that are looking at the same item. They may just have the same vehicle as you and will then know if it’s a good fit for them as well. This coolant reservoir cap fits different models of Nissan and there are a lot of reviews that just state whether the product was good/bad and or fit/didn’t fit with no mention of year and model.

good price, good fit, fast delivery
I cracked the OEM cap on my 2012 Nissan Altima coolant reservoir. This replacement was 4x cheaper than at the store (I got two for about $5, store wanted $10.99 for 1) It arrived overnight and fits perfectly.

Will easily crack
After 2 weeks, the caps will easily crack from the heat from the engine bay. Not recommendable and made of cheap plastic.

Great replacement for the coolant reservoir cap.
My coolant reservoir cap was broken, so I looked for one on Amazon, and found this. It states that it will fit my 2016 Nissan Maxima. It does. It's the right size it's OEM quality. Great value for the price. I do recommend.

A little snug, but it fits
It was a little snug for an Infiniti JX35. But just needed a little elbow grease to get it to fit.
