NHTSA CRASH TEST RESULTS
Overall Safety Rating

Frontal crash ratings:
Driver: *  *  *  *  *  Passenger: *  *  *  *  * 

Side crash ratings:
Driver: *  *  *  *  *  Rear Passenger: *  *  *  *  * 

Results based on a 35 MPH frontal crash and 38.5 MPH side crash. Results are reported in a range of one to five stars, with five stars indicating the best crash protection for vehicles within the same weight class. This test used driver and passenger belts and airbags.

NHTSA ROLLOVER RESISTANCE RATING: *  *  *  * 

The Rollover Resistance Rating is an estimate of your risk of rolling over if you have a single vehicle crash. It does not predict the likelihood of that crash. The Rollover Resistance Rating utilizes a "fishhook" maneuver which is a series of abrupt turns at varying speeds to see how "top-heavy" a vehicle is. The more "top-heavy" the vehicle, the more likely it is to roll over. The lowest rated vehicles (1-star) are at least four times more likely to roll over than the highest rated vehicles (5-stars).

Summary General Motors, LLC (GM) is recalling certain 2007-2011 Cadillac Escalade, Escalade ESV, Escalade EXT, Chevrolet Avalanche, Silverado 1500, Suburban, Tahoe, GMC Sierra 1500, Yukon, Yukon XL, and 2009-2011 Chevrolet Silverado 2500, Silverado 3500, GMC Sierra 2500 and Sierra 3500 vehicles originally sold, or ever registered, in the states of Alabama, California, Florida, Georgia, Hawaii, Louisiana, Mississippi, South Carolina, Texas, Puerto Rico, American Samoa, Guam, the Northern Mariana Islands (Saipan), and the U.S. Virgin Islands or "Zone A." Additionally, GM is recalling certain 2007-2008 Cadillac Escalade, Escalade ESV, Escalade EXT, Chevrolet Avalanche, Silverado 1500, Suburban, Tahoe, GMC Sierra 1500, Yukon, Yukon XL vehicles originally sold, or ever registered, in the states of Arizona, Arkansas, Delaware, District of Columbia, Illinois, Indiana, Kansas, Kentucky, Maryland, Missouri, Nebraska, Nevada, New Jersey, New Mexico, North Carolina, Ohio, Oklahoma, Pennsylvania, Tennessee, Virginia, and West Virginia or "Zone B." These vehicles are equipped with non-desiccated passenger frontal inflators containing phase-stabilized ammonium nitrate (PSAN) propellant. These inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, high temperatures, and high temperature cycling.
Consequence An inflator explosion may result in sharp metal fragments striking the driver or other occupants, resulting in serious injury or death.
Remedy GM will notify owners, and dealers will replace the front passenger air bag inflator with an alternate one, free of charge. Interim letters notifying owners of the safety risk are expected to be mailed beginning March 1, 2021. Second notification letters will be mailed once the remedy is available. Owners may contact Chevrolet customer service at 1-800-222-1020; Cadillac customer service at 1-800-458-8006; and GMC customer service at 1-800-462-8782. GM's number for this recall is N212328760.

News Reports & Reviews
NHTSA CRASH TEST RESULTS
NHTSA CRASH TEST RESULTS

Frontal crash ratings:
Driver: *  *  *  *  *  Passenger: *  *  *  *  * 

Side crash ratings:
Driver: *  *  *  *  *  Rear Passenger: *  *  *  *  * 

Results based on a 35 MPH frontal crash and 38.5 MPH side crash. Results are reported in a range of one to five stars, with five stars indicating the best crash protection for vehicles within the same weight class. This test used driver and passenger belts and airbags.

NHTSA ROLLOVER RESISTANCE RATING: *  *  *  * 

The Rollover Resistance Rating is an estimate of your risk of rolling over if you have a single vehicle crash. It does not predict the likelihood of that crash. The Rollover Resistance Rating utilizes a "fishhook" maneuver which is a series of abrupt turns at varying speeds to see how "top-heavy" a vehicle is. The more "top-heavy" the vehicle, the more likely it is to roll over. The lowest rated vehicles (1-star) are at least four times more likely to roll over than the highest rated vehicles (5-stars).
