2013 GMC Savana 1500 Passenger

Issue: 
On certain vehicles, an unused wiring harness for a rear HVAC blower motor, located in the left B-pillar area, could become damaged if exposed to moisture or contaminants. If this happens, the wires could short circuit.
Note: This recall only affects cutaway chassis incomplete vehicles.  

Safety Risk: 
A short circuit can create the risk of a fire. 

Corrective Actions: 
General Motors will notify owners by mail and instruct you to bring your vehicle to a dealership to seal the wiring for the rear HVAC blower motor at the left B-pillar.

Issue: 
Certain vehicles may have incorrect body control module software. As a result, the immobilization system is not active during the learning procedure for a new "unlearned" blank replacement key could be used during a 30 minute reprogramming procedure to disable the immobilization system. During this time, the vehicle cannot be driven. 

Safety Risk: 
This small error does not affect vehicle safety. 
  
Corrective Actions: 
This is not a recall. General Motors has made changes to vehicle software to ensure that all unsold and new vehicles have the correct body control module software.

Certain vehicles equipped with a hinged left side rear door may have a condition where inadequate clearance between the rear brake lines and the lower fuel filler hose clamp may result in abrasion to one or both rear brake lines. This condition could cause brake fluid loss which could result in decreased brake line pressure, increased brake pedal travel and increased stopping distance, increasing the risk of a crash causing injury and/or damage to property. This condition could cause various warning lights to illuminate in the instrument panel of the vehicle such the red “BRAKE” telltale symbol; illumination of the Stabilitrak telltale symbol; scrolling display of “Service Brake”, “Service Stabilitrak,” and “Service Traction Control” messages in the Driver Information Centre (DIC); and audible alerts/chimes.  Correction: Dealers will inspect the brake lines. If the clearance is found to be below specification, the brake lines will be replaced with a new part design that provides adequate clearance.

On certain compressed natural gas (CNG) fuelled vehicles, the CNG high pressure regulator may leak natural gas. Should a leak occur in the presence of an ignition source, a fire or explosion could result, increasing the risk of injury and/or damage to property. Correction: Dealers will replace the regulator. Note: If a leak is suspected, owners should not start nor drive their vehicles, and have the vehicle immediately towed, inspected and repaired.

Certain vehicles may not comply with the requirements of Canada Motor Vehicle Safety Standard 201 - Occupant Protection. During a frontal impact below the airbag deployment threshold, if an unbelted front passenger's head were to impact the instrument panel where the passenger airbag is located, it could decelerate at a rate higher than what is allowable by the standard. This could increase the risk of injury. Correction: Dealers will install energy absorbing trim pieces on the passenger side of the instrument panel, and on 2012-2014 model year 1500 series vehicles, dealers will also replace the front passenger seat belt retractor.
