Bought used one year ago at 100.000 km (60.000 miles). Towed a 30 ft, 6500lbs travel trailer for long distances (Alberta to British Columbia). Absolute towing beast, gobs of torque, the smoothest auto ever, very smart when trailering. Towed the same trailer with a 6.2 V8 Gmc truck and it sucked. Reved it up all the time to keep pace, fuel economy was horrible. This one just sits at 2000 rpm, 3000 at worst when going o steep uphils. Fuel economy is the same as a Sequoia empty when towing, better than a sedan when empty. 1100 kms on a tank frequently (650 miles). Quality all around, comfort is supreme. Built like a tank. Problems?Hid light, rear electric hatch lock replaced, turbo oil leak.
Diesel diesel diesel! Air ride, leather, rear camera, intelligent auto.
Wobbly ride sometimes, more diesel engines! Where is the Cdi v8 from Europe?!
Purchased new, our 2008 GL320 ate us out of house and home in 2013. When it hit 80,000 miles, we 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. In 2015, we had to replace both rear air struts and a leaky fuel injector that was causing strong fuel odors inside and outside. And since 2015 we've been experiencing a strong exhaust smell inside the vehicle, when stopped, even when the AC recirculation switch is on. I've had the exhaust smell investigated multiple times by a local Bosch certified auto shop to no avail. My tire dealer is looking at that again today while it's up on the lift and if they don't find anything, I'll take it to the dealer next.
Owned GL320 for 2 years. Nothing but problems. Very cheaply built, cheap and nasty components and plastic, e.g. some sort of plastic covering film started piling off the steering wheel controls. Fake wood trimmings, face leather, etc. Later on I discovered that it has common base and components with Jeep. Mercedes Customer Service is famously the worst (watch the Top Gear) and in deed it is!
Had car for 4 years. Numerous issues-failing suspension, rear hatch, electronics, etc. Nice car when it's running. I'm convinced they are lemons from the start. Now at 110000km steering rack needs to be replaced. Mercedes staff see you as a money bag, no help, would not stand for their product. Mercedes should be ashamed of building such a poor quality product. In order to preserve my sanity moving to Lexus- boring is goooood!!!.

Trust me when I say all European luxury SUV's have these kinds of issues. My previous car was a Range Rover HSE and a V8 Tuareg before that. Both had multiple air suspension issues, engine oil leaks, sensor failures, steering column replacements, etc... Friends with X5's don't fair well either. My RR even needed a drive shaft replacement. Fact of life unfortunately, if you want the luxury and style of the Euro SUV's the price you pay is well beyond the window sticker. The key is to enjoying the vehicle is pick the brand with a nearby dealership that treats you well and expect to spend your free time there:) - I tried the Lexus route for a year, just too bland and predictable.
Styling, quality of materials, performance, comfort.
Build quality seems great given the fit and finish, so it seems the major issues are with the EU suppliers of system components and the over-engineered systems.
Most of the EU cars source from Bosch and other EU parts companies for control systems, sensors, etc... hence the same issues across all brands.
I wish the EU makers would maintain focus on design and quality whilst reducing the engineering complexity to improve reliability.
