  Gl 450 Major problems - 2008 Mercedes-Benz GL-Class
  By tnance - June 18 - 12:20 pm

  I purchased the Gl 450 4.7 Ltr about 1 year ago. It has spent over 2.5-3 months at the dealership while attempting to fix electronic problems. While driving the vehicle it would surge and then the warning lights would start lighting up like Christmas. The lights warned of the following failures ABS, Air bags to many to name they were all on. Then a big red box on the led would state drive to the dealership immediatly without shifting gears, how you do that in an automatic Im still trying to figure out. We live in an isolated state with few roads and long distances between help. My faith in the Gl is gone! Hope no one else has experienced this. It still looks nice parked in my garage.

  2013 has been a Very Bad Year. - 2008 Mercedes-Benz GL-Class
  By cc57 - August 27 - 9:49 pm

  Purchased new, our 2008 GL320 has been eating us out of house and home in 2013. Since it hit 80,000 miles, weve had multiple, expensive repairs with each being about $1,500 to $1,800. In this order, left front air strut replaced, turbocharger replaced, fuel pump replaced, right front air strut and air compensator valve replaced. Both the turbo and fuel pump failures left us stranded and required towing it to the dealer. Unfortunately, we did not purchase the extended warranty as I thought that a diesel would be bulletproof. Obviously, I was very wrong.

  Worst car I ever owned - 2008 Mercedes-Benz GL-Class
  By Done with it - September 19 - 2:00 am

  This car could be great if only it wasnt constantly returning to the dealer on the back of a tow truck. We bought it new and within 6 months the front engine gasket blew out. Two months later the same thing happened, but this time the leaking oil caused a serpentine belt failure and we lost the steering -- not good when driving down the road in a 3-ton SUV. A few months later the power steering pump failed. Today we discovered oil all over the garage floor. Absolutely unacceptable reliability. As soon as the Mercedes dealer patches the thing back together it will be off to the BMW dealer to trade it in.

  Our first Mercedes-Benz - 2008 Mercedes-Benz GL-Class
  By KBKBDB - August 26 - 3:26 am

  So far, so good. We were in the market for a SUV. Test drove the Acura MDX, BMW X5 4.8i, and the GL. We were impressed by all three vehicles but ultimately the GL was the way to go--truly appreciate the usable third row seats.
