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?

Thanks.

Hi,

I bought a Nissan Pathfinder MY19, year 2020 and has the same problem. I took him to the workshop once and the problem persists.
I have 18 Altima and that warning light.,with the beeping came out in mine ,I brought it to my local Nissan dealer ,they replaced the sensor in the bumper no question asked .n/c
Same here! Went in for an oil change on my 2018 Altima and mentioned the sensor going off for no reason. They did a test and ended up replacing it right then and there!
I have a 2018 Nissan Altima. It currently has 40k miles on it. Recently, when I'm driving, (even with nothing in front of me) I will hear a beep, then a message comes up "Unavailable: Front Radar Obstruction." Then an icon will appear on my dash of what looks like two cars crashing. I made an appointment with a Nissan dealer and they informed me that I need to have my front radar sensor in my bumper replaced- this particular part and action will cost me around $1600. The warranty expired at 36k miles so there's no help on that end. I held off on fixing for now- that's a huge bill, but I'm wondering, will I cause further damage to my car by driving with a faulty front radar sensor? My cruise control works fine. Is there a way to turn the front sensor off completely? I've read a lot of complaints from Nissan owners with the same issue as me- why hasn't a recall be issued?
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 have the same issue with my Nissan Kicks SR 2018. Lately, when i drive on the highway, it will beep and show UNAVAILABLE FRONT RADAR OBSTRUCTION. I contacted Nissan and told me to call my local service specialist. If i take this to them, will they fix it and free of charge? I bought mine last October 2019.
I have the exact same issue. Just bought my car less than 2 weeks ago and the little warning light came on after 2 days. I brought to the dealership and was told there is a loose bracket for the front sensor

Hi! I have the same car, same issue with the same miles. Mine came on around 36k but corona virus and I didn’t really think too much of it. Thought my sensor was just dirty or something was hanging in front of it as it states in the manual. Nope. Took it in to a Nissan dealership and they said it’s definitely malfunctioning and they don’t know why. Called customer care to make a complaint and they said there’s nothing they can do. I wouldn’t be upset but occasionally my sensor will stop the car at nothing and then shut the front sensor off. Definitely should be a recall as I’m reading this is a common problem. Did you end up getting it replaced?
I just bought a 2019 Nissan Altima that was out of manufacture warranty and they are currently replacing my sensor free of charge. I had to fight with them after they attempted to clear the error and I got right back in my car and it was on again. It’s a severe safety hazard as it can quite literally stop you on the highway at 70mph if you forget to turn it off every time you get in your car. It happened to me on the way home from the dealership after buying it. They’re having a really good buy back event right now, go get yours appraised and see what they’ll buy it back for so you can make a loophole and go around it. It’s quite literally what I had to do. Bought it for $19k, they bought it back for $24k and I turned around and bought a newer 2019 with 17k miles and made them change the sensor with the 2020 version that supposedly has less issues and bought the extended warranty. 🤪

XX fuck yeah you go!!! Lady in my areas who handled my case is super rude.never got a call back about my buy back deal.
Is there another dealership near you? I mean, they’re all pretty much hurting with rona’ at the moment, so any business is business. I got my new car today with new sensor, ended up getting a 2020 Altima with 5 miles and saved $5k on my loan instead of the 2019 I was originally quoted for. It’s worth a shot calling around. I’ve also learned with these vehicles especially with the CVT’s that it’s not a bad idea to purchase an extended warranty, so see who’s offering and what price.
Some '18 Muranos were having the same problem, mine being one of them! They replaced the unit and all now seems well.
My 2018 has the same problem and the dealer said it wasn't covered under warranty.... costs over $1000.00. was yours replaced under warranty and what dealer.
It is a little box on the front right of your bumper. The radar had an angeled plate around it.

You'd think with all these cars having an issue with this, even after multiple attempts to repair, Nissan would come up with a jumper that would trick the radar into never going off.
Has anyone heard of a mechanic that has figured out how to do this?
Yank the sensor, how hard can it be? Anybody thinking beyond 5 seconds would have realized how much trouble that system would give. I for one saw it coming, no more Nissan for me.........

Cars give the least trouble devoid of all gimmick options and the way I like them.

I have the very same issue with my 2020 Nissan Pathfinder. The car is right at 2 yrs old, has 15K miles or so, I don't do long distance driving, but recently made 4 trips over the Causeway Bridge-(27 miles in length, over Lake Ponchatrain) where I tried to use the cruise control. After 5 or 10 mins driving, the Front Radar Obstructed warning came on and the collision waring system inactive message came off. 5 min or so later, the warning went off. I again tried the cruise control to have the same thing happen. No bad weather , no puddles or A/C water drips in any of the cases, no cars in front of me in any of the cases. I took the car into the dealer, who said they could not find anything wrong, they feared it was the Causeway Bridge itself causing the problem but they would call an offsite engineer(?). They called me a day later to and advised the engineer they spoke with had no remedy and agreed with the technician that the problem was due to some "mystery" occurring on the Causeway Bridge. Solution being not to use the cruise control when driving the causeway or to turn off the safety features.... I emailed Nissan consumer affairs who did call me, acknowledged he researched the Nissan repair notes when I took it in, but since he was NOT a technician, had to go with the word of the dealers' notes-the cruise control was NOT going to work on the Causeway Bridge (he added may be due to speed traps???) He said since he was not a technician he could offer no solution . His cusumer affairs remedy was to return to my dealer again or to have the cruise control checked out at another dealer. When I said I would have never purchased the car to begin with had I known the cruise control was faulty-and did I need to hire an attorney to get it fixed, he offered to check into finding out if there was a possibility of Nissan buying the car back...Now, why would they want to buy the car back instead of fixing the problem. I'm so disillusioned about Nissan.
