Hyundai Repair Questions? Ask a Mechanic for Answers ASAP
Hello, did they tell you it was the occupancy sensor?
If they are saying the passenger presence sensor is the cause, then $1500 sounds a bit high.
The seat needs to be remove from the car, lower seat trim cushion cover removed, to allow sensor replacement.
Have you had a quote from a Hyundai dealer?
Do you need any further help?
I hope my advice has been of assistance to you.
