seat belt chime starts to beep after putting the car in park and letting passenger out of rear seat and starting to drive again (car stays running)...happens intermittently...booster seat remains in the seat so i'm not sure if it's sensing that weight...only way i have found to cancel it is shut the car off and turn it back on...may try to move the booster next time...any other solutions?

 

The booster seat should be buckled in, if not it could cause the chime to go off.
Are you certain the passenger doesn't unbuckle before you come to a full stop or are in park?
The chime will also sound if that happens.
If the seat sensors get wet (rain/spilled beverages) that can be an issue and like any electronic they could go bad/be defective as well, but not likely.
You can disable it if you have the right tool and or have the dealer do it.

 

thanks...i'm talking about a backless booster car seat which are not supposed to anchored in but the child is buckled with the car's shoulder seat belt...infant rear facing car seats or toddler/child forward facing car seats are anchored into the anchor points in & behind the seat and the child is buckled in to the seat and do not use the car's seat belt system...you may be right about the buckle being undone before the car is in park...i will have to pay a little more attention to the timing of when it's unbuckled from now on to see if that is the case...when i do a drop off i put the car in park, get out, let her out, say goodbye, get back in, start to drive and the beeping begins...i was wondering if it had something to do with seat weight sensors cause sometimes one of the dogs will stand on her seat as i'm unloading her to get in 1 last goodbye

 

You may also look into the buckle to make sure it is clean and debris free.
Occasionally this issue comes up in the shop and I just have my shop janitor (best disruption so I don't have to charge for a service) blow out with air hose and wipe the insides of the buckle.

You would surprise what can get caught in their?

 

Most seatbelt sensors require 40kg or about 90lb to trigger.
More likely your passenger might be unbuckling before you are stopped or were in park than a bad sensor.
And as Cali said the belt clip can get dirt or debris in them.
When my son was little a "Swedish Fish" gummy candy required an intricate extraction.
I'm fairly certain it just didn't fall in either, let your investigation begin.

 

I always have the curtesy plastic mat protector on the drivers floor mostly as a curtesy but I don't want whatever is on their mat to get on the bottom of my shoes. As well I NEVER reach inside the interior of any area (under dash exception) unless I can see what's their first, and NEVER EVER touch the steering wheel without a clean pair of Nitrile gloves on.

 

will check the buckle...doubt there is anything in there due to the dog seat cover being over them and having to dig through the access hole each morning to find the buckle but will check anyway...i actually need to cut that access hole larger anyway to make this process easier

daughter is way under 90 lbs so i assume she is unbuckling prior to being in park

 

This post reminds me of the old Top Gear episodes where they trio would have their car interiors cleaned and the debris analyzed as to what was in it. Some very interesting results there.

 

Go under settings, and look for rear seat alert. You can turn it off in settings.

 

The owners manual may be a better place for owners to look first?

It is my experience (based weekly customer coming into the shop asking simple question that can be answered in their owner's manual) that 9 out of 10 owners NEVER completely read their new vehicles owner's manual.
