I discovered that the sonar on the rear bumper, the outer ones (on left-most, and right-most) aren't triggering a beep when obstructed. However the middle ones are. Is this covered under Infiniti CPO warranty? If not what will be the cost of this repair? I have 33K miles on the vehicle as of today.

 

Should be covered under the warranty, Bring it to them and ask.

 

Check what the sensitivity level is set for them. The outer and centre ones can be set differently and it could be turned all the way down.

 

I checked the sensitivity earlier, and maxed it out and then checked again. Same issue.


To test, I put the car in reverse, put the parking brakes on, and then covered the sonar with my hands and it triggered the beep on the middle two. However not the outer two. Please let me know if there is a flaw in how I checked and if I am missing some key info. At the moment, I have to backup my car extremely closer to a car/object that is behind me to trigger the sonar beeps. I am not sure if this is normal as well, since I do not know another infiniti owner to compare it with.

Update :

Called Infiniti Dealership and they said that it should be covered under warranty. I have the CPO vehicle and the service advisor said that it should be still covered. Hope it holds true when I get there. Catch is, they have to identify whether it is the Sonar / Radar itself or some wiring or what not, so it may take a few hours. I will post updates after the work gets done next week.

Thanks All.
