NHTSA Complaint #11495916 — 2021 NISSAN MURANO

The problem we have with the Murano is the cruise control. We live in a mountainous area and the issue we have is the cruise control will not maintain our speed when going downhill. It wasn't until we had bought the car that we learned that because the vehicle is equipped with a CV transmission that the car cannot downshift to slow the car down in a dissent. The first time we hit a downward slope heading home from the dealer the car increased in speed twenty miles over the set speed. The only waring we got was the cruise control set speed display was flashing. Had we known that the Murano was not able to maintain a reasonable speed going downhill we never would have bought it. We raised our concerns about the cruise control issue to the dealer we purchased it from, and they told us that the manual states that the cruise control won't maintain a reasonable speed in a downhill. Never explaining why it doesn't. We finally got the answer from another Nissan dealer. He explained that a CV transmission cannot downshift to slow a vehcle down because it doesn't have gears. I have spoken to our people that own vehicles with a CV transmission and that their cars can hold a set speed by throttling down and apply brakes. We spoke to a Nissan representative and she had us take the car to another dealership for a diagnostic test, which we did, but never got a response from them. Again, let me state that we would have never bought a car that cannot maintain a reasonable speed going downhill had we known.
