What Common Problems Does the 2021 Mercedes GLE Have?

Common problems reported on the 2021 Mercedes Benz GLE include excessive battery drain, safety sensor issues, along with a frozen stereo system. Overall, these problems are similar to other luxury SUVs on the market, but repair costs are usually more expensive due to the high parts and labor costs on Mercedes vehicles.

Excessive battery drain is the most widespread complaint from 2021 GLE owners, showing up within the first 3,000 miles. There are a lot of electrical accessories in the GLE, which sometimes draw power even while the engine is off. Diagnosing the source of the electrical draw costs around $100, while fixing it can cost $50 to $400.

Safety sensor issues have also been reported by some Mercedes GLE owners within the first 1,500 miles. The front braking sensor sometimes fails, and has to be replaced. When the vehicle is under warranty, it’s usually covered for free, but out of warranty the sensor costs around $950.

A frozen stereo system is another problem mentioned by some 2021 Mercedes GLE owners at around 1,000 miles. There are software updates available for the stereo that improve the reliability. Most dealers will install these updates for free, while others charge around $100 for labor.

Mercedes will replace the fuel pump on affected models for free. Other recalls cover the battery ground, rear door window trim, along with the steering system. Mercedes will fix those issues for free as well.

How Long Will the 2021 Mercedes GLE Last?

A well-maintained 2021 Mercedes GLE can last around 200,000 miles, which is shorter than the long-lasting Lexus GX. Regular annual maintenance costs are higher than average, according to data provided by Repair Pal, at $1,174 per year.

As a used 2021 GLE reaches 100,000 miles, and depending on the vehicle history report, owners should be prepared to replace the stabilizer bar links for $225, a variable valve timing solenoid for $350, along with the control arm bushings, which cost around $650.

What Colors Does the Mercedes GLE Come In?

How Comfortable Is the Mercedes GLE?

The 2021 Mercedes GLE stands out in its class for its exceptional comfort, offering a driving and riding experience that is both luxurious and relaxing. This SUV has been designed with a keen focus on passenger comfort, making both short commutes and long road trips a pleasure. The interior of the GLE is a testament to Mercedes’ commitment to luxury, featuring high-quality materials, elegant design, and meticulous craftsmanship. The seats, upholstered in premium materials such as leather or MB-Tex, provide excellent support and comfort, even during long drives. The front seats are not only power-adjustable but also come with heating and optional massage functions, providing a comfortable experience for the driver and front passenger.

The GLE’s comfort extends beyond its plush seating. The vehicle’s advanced suspension system plays a pivotal role in providing a smooth ride, effectively absorbing bumps and uneven road surfaces. This, combined with the SUV’s well-insulated cabin, makes sure that road noise and vibrations are minimized, creating a serene environment inside. The climate control system is equally impressive, offering precise temperature adjustments and guaranteeing that all passengers, regardless of their seating position, remain comfortable throughout the journey.

Additionally, the 2021 Mercedes GLE is equipped with a host of convenience features that further enhance the comfort level. These include a user-friendly infotainment system with voice control, ample legroom and headroom in both the front and rear seats, and an optional panoramic sunroof that adds an airy feel to the cabin. All these features come together to make the 2021 Mercedes GLE not just a vehicle that’s comfortable to ride in, but a space where passengers can truly relax and enjoy the journey.

How Much Storage Space Does the Mercedes GLE Have?

The 2021 Mercedes GLE is renowned for its luxurious interior and robust storage capacity, making it a prime choice for those who prioritize both comfort and practicality in their vehicle. It boasts impressive cargo space, providing ample room for a variety of storage needs. When all seats are in use, the GLE offers about 33.3 cubic feet of cargo space. However, when the rear seats are folded down, this space expands significantly to 74.9 cubic feet. This expansive area is more than adequate for everyday needs and is especially beneficial for longer trips or transporting large items.

In terms of what this space can accommodate, with the seats up, the cargo area can easily handle a family’s weekly grocery haul, several large suitcases, or bulky items like a baby stroller. When the seats are folded, the space becomes generous enough to transport larger objects. For instance, it can comfortably fit several large pieces of luggage, sports equipment like golf bags or skis, or even furniture items like a small couch or a couple of flat-packed bookshelves.

Besides the primary cargo area, the 2021 Mercedes GLE also includes numerous small interior storage spaces designed for convenience and organization. These include a sizable glove compartment, door pockets in both the front and rear, a center console compartment, and cup holders. There are also additional storage spots beneath the cargo area floor, ideal for storing smaller items out of sight or keeping valuables secure. These thoughtfully designed storage solutions make the GLE not just a vehicle with substantial cargo space, but also one that excels in keeping the interior neat and organized.

How Does the Mercedes GLE Compare to the Competition?

The 2021 Mercedes GLE is a nice midsize luxury SUV which has a lot of upscale features, but shoppers should be prepared for the higher maintenance costs as it ages.

The BMW X5 is another midsize luxury SUV which costs about $1,500 less. Steering is more responsive in the BMW X5, while the Mercedes GLE offers a higher-quality interior. We recommend the BMW X5 since it’s more fun to drive, but both are worth testing to see which you prefer.

The Audi Q5 is a popular competitor, which is around $3,000 less. Standard technology is a bit better in the Audi Q5, while the Mercedes GLE has better seats. We recommend the Audi Q5 since it comes with more features, but it’s worth taking both out for a test drive to see which you like better.
