Driving north on the garden state parkway in the center lane it felt like I had a back tire blowout but what happened was my rear axle broke causing my vehicle to be extremely hard to control. I was trying to steer the vehicle but could not control the truck, it felt like I had limited braking ability, smashing into guardrail it finally came to a stop.

Tl* the contact owns a 2015 GMC sierra. While driving at various speeds, both low and high beam head lamps failed to fully illuminate, which diminished the contact's visibility. The vehicle was taken to a dealer who was unable to diagnose or repair the vehicle. The manufacturer was notified of the failure. The failure mileage was 5,000. Updated 04/06/16 the consumer stated the vehicle lights are working, but they do not illuminate the road well enough. Updated 11/21/2017
Headlight performance is very poor with weak yellow beam both on low and high beams. Difficulty seeing during night driving, especially at highway speeds in dark areas, is very hazardous, even worse during rain. I am concerned about my safety and that of my family while driving this truck at night. The projector-style headlamps on the vehicle were dim with a yellow color and provided inadequate front and side illumination. The headlight aim was raised, which resulted in little improvement.
