The Mercedes-Benz GLC 300 blends performnace and luxury in updated packaging for 2021, keeping it fresh in the compact luxury SUV segment. The GLC has always been a great SUV, but the modernization has done the Merc well, and the interior is as sumptuous as ever, now with the MBUX infotainment suite to match. The benchmark for midsize SUVs takes bold steps ahead in every measure. A boost in turbo power, confident all-wheel drive, innovative luxuries, advanced safety, and a spacious, sensuous cabin are all wrapped in a fresh new style.

Look at the purchase prices, and the GLC isn’t the cheapest option compared with an Audi Q5 or BMW X3, but it is competitive on price once you factor in the standard automatic gearbox four-wheel-drive system.

How reliable is the 2021 Mercedes-Benz GLC 300 SUV?

Mercedes sits near the bottom of the JD Power Vehicle Dependability Study in the manufacturer rankings, which could be cause for some concern. That said, the brand still placed higher than its main rivals in Audi, BMW, and Jaguar, and the same has also been true in the same study over the last few years. Like other Mercedes models, the GLC comes with a three-year/unlimited mileage warranty, which is a bit more generous than the industry average.

How much did the 2021 Mercedes-Benz GLC 300 SUV score in J.D. Power Rating?

J.D. Power rating or James David Power ratings is a 1968 American based data analytics and consumer intelligence company that is reputed as " A global market research company" and conducts automotive surveys that thus predict the reliability of a vehicle.

The J.D. Power rating conducts multiple annual surveys that include a Vehicle Dependability Study (VDS) that acknowledges problems experienced after three years of ownership, along with an Initial Quality Study (IQS) that aggregates issues encountered within the first 90 days of ownership. Thus a buyer can refer to these ratings, including short and long-phase problems and reliability issues, and make a modish choice.

The 2021 Mercedes Benz GLC 300 SUV remains unrated by the J.D Power Ratings. However, the 2020 Mercedes Benz GLC 300 SUV has been rated with pretty good figures, an overall score of 80 out of 100. This comes with the average of the following score:

  • Quality and Reliability- 77/100
  • Driving Experience- 82/100
  • Resale- 80/100
  • Dealership Experience- 83/100

Has the 2021 Mercedes-Benz GLC 300 SUV had any Recalls?

The 2020 Mercedes-Benz GLC-Glass range has been at the center of three recalls for issues including an inaccurate location being sent to emergency services in the event of an accident, an unsecured driver's airbag, and active brake assist not engaging properly. The 2019 model didn't fare much better and was victim to five recalls for issues including a loss of electric power steering and an incorrect display of the passenger airbag status if reliability is a concern.

Have there been any consumer complaints about the 2021 Mercedes-Benz GLC 300 SUV?

The 2021 Mercedes Benz GLC 300 SUV has no consumer complaints, but the same can't be said for the 2020 GLC 300 SUV. One of the consumer complaints includes automatically changing the set speed limit as the road speed limit varies. These features come very handily for the safety fronts. Still, the system needs updates to stop disturbingly changing the cruise speed, whenever no required, or some warning message should warn the driver for overspeeding the road speed limit.

2021 Mercedes-Benz GLC 300 SUV Warranty coverage

If reliability is a concern, Mercedes-Benz offers a basic warranty of four years/50,000 miles and a drivetrain warranty that's valid for the same period and mileage limit.

  • Basic:4 Years/50,000 Miles
  • Drivetrain:4 Years/50,000 Miles
  • Corrosion:4 Years/50,000 Miles
  • Roadside Assistance:4 Years/50,000 Miles

Is the 2021 Mercedes-Benz GLC 300 SUV reliable enough?

The flaws of the Mercedes-Benz GLC300 are pretty minor, especially when compared to its competitors. Because of its respectable gas mileage, superior quiet comfort, semi-autonomous handling, and advanced MBUX multi-media system, the reasons to like this car far outweigh its flaws, setting the GLC300 apart from its luxury compact SUV competitors.
