The NHTSA (National Highway Traffic Safety Administration) has opened a problem involving 2.7 million SUVs and trucks manufactured by General Motors because of a braking ability that deteriorates over time.
What Vehicles are Affected?
The vehicles involved are all 2015 and 2016 model years and include the Chevrolet Silverado 1500, Cadillac Escalade, Tahoe, Suburban, GMC Sierra 1500, Yukon XL and Yukon makes.
Why It’s Happening
The NHTSA believes the problem could stem from the vacuum pump that is engine-driven and brake-assist. This pump helps to bring the vehicle to a full stop. With time, this part’s assistance can weaken and even lengthening the distance to stopping. Longer stopping distances can increase risk of a crash, especially if it goes unnoticed and the driver must brake quickly.
The NHTSA is not currently ordering a recall of the almost three million SUVs and trucks. However, the current probe does require more analysis, and it could trigger a recall. The NHTSA and GM haven’t offered suggestions on what drivers should do to keep their vehicles in proper working order.
If the vehicles are recalled, it would be the second recall for GM. The first totaled over one million trucks this past year because of an electric steering issue.
