Random chime

Nothing in the owners manual?

The manual describes several sounds but none of the causes for those are possible when I hear the sound.

Ideas, just the norm. Seat-belt, low fuel, maybe a loose gas cap, this sound is just a reminder that something is on, or going on. This is too new of a car to have history of problems for me to have learned. But this has to be something simple, and what gets me is that a dealer doesn't even know. There has to be some sort of warranty on it, I would let the dealer figure it out. Sorry.

Was looking for an answer myself. 2014 CX-5 with exactly the same condition (not annoying but curious as to what it is) Dealer doesn't know. My guess is something to do with their SCBS (smart city brake system) as my chime seems to show up more often while exiting the highway and entering an area where there are traffic lights. (SCBS activating??)

I believe I have found the answer to the random chime. While driving with the navigation on (though it doesn't have to be) I had my mysterious 3 chimes coming up to a intersection with a traffic light. While stopped at the red light, I noticed on the screen a flashing icon of a camera. I now believe that the car gives a warning of any traffic light intersections that have a video camera monitoring that location. Pretty cool, though I have to see how much time they give before getting to the intersection.

What will they think of next....lol

I have a 2015 Mazda 6 doing something similar. Did your radio sound level lower as well with these chimes? I am trying to figure it out as it just started happening about a month ago but have had the car for almost 2 years.

I have a 2014 CX5 - these random chimes started last week after my car was jump started. My radio sound lowers also with these chimes. Do not seem to be related to intersections or anything in particular. Dealer workshop is still trying to figure it out. Any ideas?

Same here! I have a 2015 CX5 and the 3 chimes sound at the very same locations around town. I asked Mazda service and they have no clue. The radio volume DOES lower when the chimes sound. As I said, the chimes sound at the very same locations all the time, I will keep an eye out for any similarities in the locations the next time I am in the area.

Similar issue here - 2016 CX-5 and the other day it just started dinging like when you start the car. Not the alerts you get from the camera, smart city braking, blind spot monitor, or anything like that. Just like when you leave a door open or don't fasten the seat belt. No idiot or warning lights are on. Nothing in the system apps show any warnings or maintenance due. Sometimes it dings for 3 times, then 4 then 7... sometimes it dings for like 2 minutes. No idea what is going on here.

The same thing happened to me for the first time yesterday twice about 5 minutes apart. Drove me crazy the whole way home, reading all the comments above, it's nit an intersection issue, I drive the same route everyday. but what I did nitice was the outside temp said 100, then 101, then 100 and the chimes again. I have a 2016 cx5.

We had that noise in our 2016 CX-5 too. It was after buying a gallon of milk, and putting it on the passenger seat. It must have been the seat belt warning chime. Put the gallon of milk on the floor, chiming gone.

I discovered that it was not my car at all. My Garman GPS chimes when I approach a school zone. The problem was too much technology for an old person. ;-)

I think GuruDTVN2 is on to something. Shortly after posing the question here a few weeks ago, on a haunch, I asked my wife if there was anything on the front passenger seat. She had a small, light bag on the seat. Normally there is a light to tell you that it senses weight on the seat but won't turn on the airbags because the seat belt is not on. I asked her to take anything off the passenger seat and buckle the passenger seatbelt. The ding never came back and has been gone for a few weeks now. My theory is that over a bump or something, the seat sensor was sensing the weight of the bag momentarily as enough to be a small person on the seat. It wasn't long enough to trigger the visual alert to show the seatbelt wasn't on, but the audio alert continues to ring for a bit and repeated small bumps may have kept triggering it - again, just not long enough to show a visual indicator. It's my theory anyway.

I have 2015 cx5. I bought it new and had not heard anything until I upgraded tomtom navigation system. I started hearing this 3 chimes at random times. I asked my dealer, they had no clue. It drove me crazy until I finally found an answer. It was a navigation system warning sound when approaching speed or red light cameras. Check link below for more info and how to set it or disable it. It's a great feature! I love my Mazda again! http://mazdanav.com/user_guides/navigation-reference-manual-english-us/speed- cameras/ I hope it ends your misery. Lol. Barbara

I believe the chimes are detecting school zones. I own a 2015 ford edge that has stopped chiming. Ford dealers don't have a clue. I also have a Garman connected.This is where I am goibg to explore.

My Cx5 2014 started beeping at 25 second intervals. It is still beeping even when the engine is off and ignition and all systems are powered down. My vehicle had been stired for 3 weeks in an outdoor vehicle storage and it had been raining heavily for 3 days solid before I tried starting it. It started ok but so did the beeps...

It makes noises for different reasons which you can turn off and on and change the sound. Approaching school zone, speeding more than set limit, red light cameras, potential speed traps.... Etc. You can change the warning sound or turn it off. When the music is loud, in order to warn you it will decrease volume and move music to the rear, since it's probably too loud for you to hear warning chime.

I've had a certified used 2016 CX-5 for one week. I've gotten the chime on three different occasions and I'm not sure yet but I think it might be when I have things on the passenger seat, like my phone and keys.

I get the sound briefly in the same exact areas in 3 places in st Louis. Near the airport when I exit to go to the parking spot and 2 different spots at the Grand and 44 exit. There are traffic cams all over St. Louis so I don't know why this occurs at these 3 spots consistently since I bought this CX5 in Feb 2013.

I have a 2014 Mazda 5 . It has recently started sounding the pleasant "bong" chime. It could be anything, but I've read the warnings in the manual and it's not mentioned there. Maybe it's when I have bags on the passenger seat.

Anyone get any answers on this random sound that occurs when I go through a specific location in my neighborhood? Specifically sjw1961 and wacki56? We seem to be having the exact same issue. Thanks for any help.

Wally Argus 4:45 PM (0 minutes ago) to CarGurus I finally figured out that it was my GPS notifying me of a school zone. It had nothing to do with the car. It is hard to tell where a beep is coming from.

I have the same issue -- generally a 7 chime ring about every 30 seconds or so. But I don't have a navigation system in my CX-5. I might have had something in the passenger seat. Will check that.

I think it happens when you're on the phone that is connected (maybe to carplay).

We hear a melodic single tone that the original post is referring to. Mostly when sitting idle; not correlating to an intersection. Strangest sound - almost bird like.

2020 cx5. Does the same thing. I was passing a cop today and then a school zone miles away. Happened each time. Radar detector? Hey Mazda...can you help us all out with an answer?

Found it! SOLUTION: In Nav menu select Services, then Disable Alerts.

I had this problem for a while. When I reset my cell phone on BlueTooth it went away.

In my car it was the NAVI that ping ping ping. I set the volume to 0 and no more ping :-)
