Do Not Buy!!

Bought this car used with only 1100 miles. I have had it towed three times due to not starting due to constant software issues. It also will never read the key through my purse or coat pocket. I have to take the key out and hold it in front of the steering wheel for it to acknowledge it. Finally, one of the cameras does not work correctly so I constantly have a notification for that on my dash. That part has been back-ordered for months. I would not recommend this car. It has been a total nightmare.

Totally Agravated Horrible New Car Experience

I purchased my Gls 2021 last year from White Plains Mercedes brand new and in 6 months there was an indicator for the 12 volt battery that powers the starter is low. That indicator went away. A month without any warning after that i go into my garage to start my vehichle and it would not start. I had to get it towed to Virginia Beach Mercedes Benz for service. I was told they had to change the main battery and update and program software in the 12volt battery. A month later the car would not start again i had to have it towed again. Filed a complaint with Mercedes USA and they were very dissmissive and unaccomodating to my issue. I asked the customer advocate what is a reasonable amount of times that my new car have to malfunction and having to be towed in for service for you to take the car back and give me a new car that is dependable and reliable and that works. I paid for a new car and this car is malfunctioning like a hooptie The advocate from corporate would not answer that question and was very dismissive. I was told by service for the second tow that my car did not start due to a soft ware update. Mercedes is clearly having problems with their Gls 450 2021. I do not recoomend this car. For the amount of money paid for this new vehichle i expected a better response and more accomodating from the corporate advocate.

Best SUV we've ever owned.

Exceptional vehicle in the SUV class. We drove the BMW X7, Audi Q7, Volvo XC90 and this GLS 450 just kept blowing them out of the water. The ride is amazing and we feel the comfort level and size is the best

You get what you pay for

We are in our first five months and I seriously believe all the safety options have kept me out of at least two accidents. The car on the highway practically drives itself while giving me a message. Audio systems are excellent. The 450 GLS makes driving a bit of a joy.

Poor reliability

I think this car is over engineered - tons of electrical issues- not worth the money or aggravation- at 1100 miles- the car shouldn’t have any problems. Would never get it again.

Great car!

Luxurious to drive and very quiet riding car. I am very satisfied with the car. The electronices are a bit over whelming at first. Love the car.

Great Electronics and Engineering

This car is state of the art in human factors engineering. It has multiple layers of safety enhancements. Interior is very spacious. The 42 volt battery provides quick acceleration which allows the car to have no lag time when accelerating.
