Those codes are related to the CVT--sounds like you might need a new one which could be $3-$4K or more depending on where you live and who does the job. Did you notice anything out of the ordinary with how the car was driving?

Any time you get CVT codes it's a matter for concern. You might try a preemptive change of lubricant in the CVT. The only lubricant approved by Nissan is sold by dealers and it's not cheap, but worth a shot at avoiding a CVT problem.

You can look up the basic meanings of all these codes online:

https://www.autocodes.com/p1715_nissan.html
https://www.autocodes.com/p0840_nissan.html (might be a valve body issue, which is a lot cheaper than a transmission!)
https://www.autocodes.com/p0845_nissan.html

Two of those seem to relate to pressure sensors, which might be the sensors or a pump not creating needed pressure.

I'm guessing that your mechanic is an independent shop, which is fine with me. To fully interpret these codes, a dealer might be helpful. Depending on the analytic equipment your mechanic has, a dealer may be able to get more detail from the codes.

One thing to keep in mind: you can't replace your Murano with a comparable vehicle with the same mileage for $4,000. If a replacement CVT is needed and costs $4,000 it makes economic sense to consider doing the repair instead of changing vehicles.
