door open light sensor - replaced at agincourt mazda

[phoenix_bladen]

my door opened sensor was on even when i closed all 4 doors on my car

so i went to agincourt mazda to get it checked out and they told me it was the sensor in my car so they replaced one of them

but after 1 day of driving they came up again so the dealership got confused because they forgot which one it was so they replaced all of the sensors

uh...wouldn't they have which sensor was replaced on the invoice? Doesn't sound very professional. At least they changed all of them though. Did it solve your problem?
