What This Recall Means

Component

POWER TRAIN:TRANSFER CASE (4-WHEEL DRIVE)

What Happened
The transfer case in your 4-wheel drive vehicle helps control power to all four wheels. It's like a gearbox that ensures you don't lose traction or slip on the road. But in certain cases, the computer that controls it might not engage properly.
Risk if Unfixed
If the gear doesn't engage, you could lose control of your vehicle while it's in 'Park', which could cause it to roll away and lead to a crash.

How to Get This Fixed

Free Fix
Your dealer will update the computer that controls the transfer case, so it engages the gear properly. This repair is free, and you should schedule it as soon as you get the recall notice.

Affected Vehicles

2002 GMC Envoy
