Front Radar Obstructed?

127574 Views 35 Replies 24 Participants Last post by  Ginger Boudreaux
You're driving at 70, interstate, heading west around 10 am. Cloudy day, temp around 80.

Beep! "FEB: Front Radar Obstructed" warning appears on the panel between tach and speedo.

The "collision warning system inactive" icon light comes on.

After a few minutes, the warning message goes off; the collision warning system light goes off.

Happens again after maybe ten minutes.

It never seems to happen on slower, country road driving.

Any ideas?

I once had one freak out because a bug splatted on the sensor, and of course everytime i drive in the snow.
On both the Altima and Titan XD there is a series of sensors embedded on the front and rear bumpers for parking assist and the main CA radar is behind or near the Front Nissan emblem I think.
JG - please let us know how it goes at the dealer. I've had my 18 Altima at dealer at couple of times for routine maintenance. Service tech says there is no known fix for the problem yet.

I know that they were replacing the defective radar units with the same faulty sensors. I haven't heard if they have received updated shipments yet.
