Our new GLS580 with just 108 miles is back at dealer with severe heat issue in center console. So hot, we were worried about fire. Very disappointed that it is now laid up till issue is found and resolved. Driving it was great, but short lived for now sadly. Update - false alarm, it turns out second row system was set at factory on high heat and the second row vents were closed so all the heat that goes under console could not get out. Stupid problem that was easy to resolve. This is our third GLS and WOW what a difference in ride and technology!

The ride is absolutely stunning and the interior is downright beautiful. We love the tech and features... kids can’t get enough of the ambient lighting options. But there’s a catch. The build quality just plain sucks. We’re had the car for 2ish months, and it’s already spent 9 days in the shop. First, the high fan made a crazy loud noise. Then the rain sensing wipers didn’t sense rain. Now we have a window that sounds like it is going to fail when we roll it down. Also there appears to be a subtle fit issue on the rear bumper. These cars are built in the US, and I get the sense that they have no idea how to put them together. There is so much tech, and so many points of failure. I feel like we are going to have a very close relationship with the dealer over the life of this car. At least it’s pretty and drives well. Update on 1/4/2020 - Two more issues after getting the car back last week... a check engine light and a warning that the collision avoidance system is disabled because the sensor is dirty (the sensor does not appear to be dirty). A word to the wise... think long and hard before buying this car.

I just bought this SUV so I am just learning all it can do. The coolest thing about it is the voice-activated commands. I’ve had earlier voice-activated interfaces but they didn’t work that well. This one works. If you have an Apple you’re familiar with Siri. Here you say “Hey Mercedes”. The voice says how can I help you? You say navigate to (wherever) and the navigation routes you to (wherever). You say turn on heated seats, the car turns on the heated seats. You say call (someone in your contacts), the call calls that person. Etc, Etc. Very Cool. Six month update: I still love the car. It gets great gas mileage for a big SUV. One odd thing I could do without is when the Nav route is programmed and you come to a turn, the dash shows the view in front of the car. So the dash shows the same thing as looking through the window. It’s kinda annoying and utterly unnecessary. Just came back from a coast to coast road trip in my GLS. I still like the car, but here a a few shortcomings: Nav system wanted to route us off the interstate and through the city to put us back on the interstate?? We ended up just ignoring the nav system and continuing on the interstate. This happened multiple times. Adaptive cruise control was very aggravating. On posted 70 mph interstates, I set cruise control @ 75 mph to keep with traffic flow. The car would often catch a signal and slow to 70 mph. Additionally, car would slow around curves. Both instances very aggravating as rest of traffic continued at constant speed. Finally, the steering seemed to get squishy, or loose when the cruise control was engaged. Not sure I would get adaptive cruise control again. Positives: very comfortable ride and 26 mpg. Two year update. I still really like the ride and comfort of this vehicle. The biggest annoyance I have is the Navi guidance. It often makes nonsensical routings. I previously mentioned how it would want me to get off the interstate to go thru the city just to get back on. Another example: I wanted to find a Home Depot. It found one < 5 miles ahead on the same street I was on. The Navi wanted me to turn right, jump on the freeway, exit the freeway to put me back on the street I was already on. I ignored the Navi, just went straight down the street. I do this often and let the Navi recalculate the route from my better route. For a system that has ‘learning’ capabilities, it’s pretty dumb. Google directions is much better and gives multiple routes to choose from. Update: don’t like how message appears ‘2nd row right & 2nd row left seats not locked’ when you have the 2nd row seats down. Message appears in place of odometer read out and you have to manually toggle twice (once for each seat) every time the car is started.

We recently bought a 2021 GLS 450. The warning systems work some of the time, but not consistently. We had all the driver assist features malfunction so into the dealer. They found a severed sensor wire which Mercedes said normally wouldn't be covered (The car had 1800 miles on it), but they decided to cover it anyway. Sometimes we get an audible parking assist warning sometimes we don't. My wife managed to back it into another car and never got a warning. I understand it was her fault for relying on the back up warnings, but it is so unreliable that it is really useless. We have had multiple cars with parking assist and never had any problems. It was inspected after the fender bender by the dealer , but they couldn't find any issues. They gave us Mercedes Benz USA contact info. We have collected multiple videos of the system not working to show the Mercedes rep. When we called MB USA, they were confused as to why we were calling them and told us that there are plenty of warnings not to trust the system. Great! Does that mean we shouldn't trust the adaptive cruise or any of the lane assist features? What is the point of having these systems if they don't work. Add in to those issues the incredibly loud drivetrain (also checked by dealer, but told it was normal due to high pressure system like a diesel), I can't recommend this car. It's nice when it works, but no better than competing vehicles. Stay away.

1. Rear seat stuck on day 1. In repair for 7 days 2. Hood latch broken on day 1. In repair for 7 days. 3. Coolant alarm went off on 3rd day. In repair for 1 day 4. 2nd row center console latch broke after 1 month. Still waiting for parts since 2 months ago. 5. Dealership (Mercedes Benz of Walnut Creek CA) was not forthcoming when I got delivery. Although the price was similar, the car sold to me was missing a couple of items I special ordered. I trusted they would tell me if my order wasn’t met. So if you custom order from this dealership, make sure you run through your checklist before signing. I made a mistake of trusting them to tell me it was incomplete.
