Six problems related to seat belt have been reported for the 2002 Chevrolet Suburban. The most recently reported issues are listed below.
Overly sensitive seat belt mechanism. Slightest movement while driving will cause seat belt to lock, restricting the person driving from necessary movement such as, looking behind vehicle before reversing or lane changing, taking the ticket from machine in parking structures, ect. Seat belt has been changed once but continues to be a problem. Problem has been with auto since purchased.
The set belts locked up without the brakes being applied. Passenger seat belt shoulder harness only will not unlock, unless the seat belt is unbuckled and retracts back.
Seat belt retractor locks up.
All passenger seat belts get tighter while vehicle is moving- it feels like you are being sucked into the seats- it also makes taking a breath diffulcult- the tighter the seat belts get the harder they are to unlatch- the make do correction offered by Chevrolet of using a seatbelt extension is unacceptable as it places the buckle and connections over the center of the abdomen/chest area.
Contact states; front passenger seat belt will tighten and lock while engine is on and off. Just to unlock seat belt at latch and allow it to roll all the way in before it can be applied. It tightens as if brakes were slammed on. However it tightens anyway without that particular situation. Has taken to dealer twice without any conclusions or repairs.
The front passenger , the second seat passenger and the third seat on the driver side are defective. When riding, the seat belts will lock into a position where you can't immediately get out of the belt. The belts have been serviced on at least 3 times.
