Recently purchased a 2015 Suburban LT with 42,000 miles. The headlamps are unacceptable. Very easy to overdrive them..Old technology, and Chevorlet is aware of the issue due to TSB and design change for 2016. GM should upgrade all vehicles with updated lights. The vehicle is dangerous to drive. I also own a 2014 F150, non aluminum vehicle. Ford continued to update their vehicles with technology including the lights right up to the end of production. GM introduces a new vehicle that is sub standard to sealed beam technology. If GM does not update my vehicle this will be the last GM I ever buy.

I bought this vehicle NEW. The headlamps are too dull. Just as described in another complaint about the 2014-15 GMC Sierra. The headlamps are too dull, hard to see at night, there's NO peripheral vision on either side. When you are driving down a dark road, you cannot see on either side of the road. When turning into a driveway, you have to turn on the high beams just to see the driveway.

I brought it to 2 Chevrolet dealers and the people in the service dept said they were not aware of that problem. Had no other complaints, which I know is not true because of the comments I have read on the internet.
