Chevy Trucks and SUVs Have a Cracked Dashboard Problem
Multiple GM vehicles from the 2007-2014 model years are developing dashboard cracks. One of the most common areas of concern is around the passenger airbag cover, leaving owners wondering about potential safety risks.
Most of the affected Chevy vehicles are from the 2007-2014 models years and built on the GMT900-series of platforms. This includes the Avalanche, Silverado, Suburban, and Tahoe, as well as the Cadillac Escalade, and GMC Yukon and Sierra.
In most cases GM won’t allow owners to make warranty claims on the dash because it’s a “cosmetic issue.” OK, sure – visually it stinks, but what concerns owners the most is will a busted dash affect an airbag deployment? Will the broken bits become projectiles in a crash? How bad will the vehicle's resale value take a hit?
Oh, and then there's the whole questioning what other parts of your vehicle might be failing as you watch the dashboard fall apart in front of your eyes.
”The Avalanche we purchased has been an outstanding vehicle in many ways and we painstakingly take care to preserve the looks and mechanics of the vehicle, BUT, when out of the blue the dash cracks for no apparent reason in two different places, it makes me wonder if they skimped any where else on the vehicle” – 2007 Avalanche owner in KY
Dashboards will crack for a number of reasons, but the most common is due to the sun. Heat buildup under the windshield and exposure to UV light can dry out and break down the chemical bonds in the plastic.
But 2007-2014 GM vehicles aren’t the only ones under the sun, so why do some dashboards crack, while others don’t?
First and foremost, if an automaker uses cheap plastic for their dashboards it’s going to break down faster. It’s cheap for a reason.
Even if GM used good plastic, a bad design will create problems too.
Owners say that GM switched from a multi-piece dashboard design to a one-piece for the 2007-2014 model years. A large piece of plastic without any relief points is going to put it under additional strain.
Other owners believe that GM overtightened the bolts holding the dashboards in place during manufacturing, which would put even more stress on the plastic.
The lawsuit alleges cracks in a dashboard occur in the steering column cowling and passenger airbag area, but having the dash replaced by a dealer does no good because the same allegedly defective design is installed.
The plaintiffs say General Motors has refused to issue a recall to fix the dashboards and continues to force customers to pay for the damage. The lawsuit doesn’t cover the 2007 or 2008 model years of the vehicles we find have the most problems:
2009-2014 Chevrolet Silverado
2009-2014 Chevrolet Tahoe
2009-2014 Chevrolet Suburban
2009-2014 Chevrolet Avalanche
The GM cracked dash lawsuit was filed in the U.S. District Court for the Eastern District of Michigan - Smith et al. v. General Motors, LLC.
