General Motors has started a Customer Satisfaction Program to address an issue related to the steering wheel switch calibration on certain 2021 model-year Chevy Tahoe vehicles.
The problem: in affected vehicles equipped with the Special Service Sales Package (RPO code 5W4) and radio infotainment system (RPO code IOR), the left-hand buttons on the backside of the steering wheel currently enable favorites instead of being repurposed for the use of emergency equipment such as police lights or sirens and push-to-talk microphone.
The hazards: this problem does not pose an immediate risk to vehicle occupants. However, law enforcement agencies and other fleet customers will be unable to use the steering wheel buttons to control auxiliary lights, sirens and other equipment if this problem is not addressed.
The fix: dealers will be instructed to reprogram the radio in affected vehicles. This factory radio update will be performed at no cost to the vehicle owner.
Affected components: backside steering wheel switches.
