Analysis

What Problems Does the 2021 Mercedes-Benz GLA-Class Have?

The 2021 Mercedes-Benz GLA-Class, while generally reliable, has experienced some reported issues. Common concerns include problems with the MBUX infotainment system, such as screen freezes, connectivity issues with Apple CarPlay and Android Auto, and voice command malfunctions. Some owners have reported minor electrical issues, including sensor malfunctions and problems with the automatic climate control system. Transmission glitches, though not widespread, have also been noted.
Recalls for the 2021 GLA have been issued for various safety concerns, including issues with the emergency call system (eCall) and potential problems with the fuel pump. It's crucial to check for any outstanding recalls before purchasing a used model.
Long-term reliability can be a concern, particularly with the advanced technology and complex systems in the GLA. Regular maintenance, including timely oil changes and fluid checks, is essential to prevent problems. Some owners have reported issues with the engine and transmission after extended use, but these are not widespread. Thorough inspection of the vehicle's service history is recommended when considering a used 2021 GLA. Keeping up with software updates for the MBUX system can mitigate some of the infotainment-related issues. Specific model year issues beyond 2021 would not apply to this model year. The 2021 model is still fairly new, so very long term reliability data is still emerging.

How long will the 2021 Mercedes-Benz GLA-Class last?

With good maintenance, a 2021 Mercedes-Benz GLA-Class can reasonably be expected to provide 150,000 to 200,000 miles or 10-13 years of service. Regular oil changes (every 7,500-10,000 miles), timely fluid flushes, and addressing minor repairs promptly are crucial. Weaknesses over time may include increased wear on suspension components, potential issues with the turbocharger, and degradation of rubber seals and hoses. The MBUX system's long-term software support is also a factor to consider. Proper care will significantly extend its lifespan, whereas neglecting maintenance will shorten it significantly. The newer GLA design should offer better longevity than previous generation models.

What Technology & Safety Features are Included?

The 2021 Mercedes-Benz GLA-Class boasts a modern suite of built-in tech and safety features. The standard infotainment system includes a 7-inch touchscreen, Apple CarPlay, Android Auto, and Bluetooth connectivity. An optional 10.25-inch touchscreen is available. The MBUX system responds to voice commands using the "Hey Mercedes" prompt. Entertainment features include a standard audio system, with an optional Burmester surround sound system.
Driver-assistance features include standard active brake assist, attention assist, a rearview camera, and crosswind assist. Optional features include adaptive cruise control, blind-spot monitoring, lane keeping assist, parking assist, and a surround-view camera system.
Safety features include multiple airbags, anti-lock brakes, electronic stability control, and traction control.
The 2021 GLA received good crash-test ratings from the IIHS, earning a "Top Safety Pick" award. NHTSA ratings are also generally positive. These ratings reflect the vehicle's strong structural design and comprehensive safety features. The advanced driver-assistance systems contribute significantly to its overall safety performance. Optional features significantly enhance the tech and safety beyond the base offerings.

How Does the 2021 Mercedes-Benz GLA-Class Compare to Other Sport Utility Vehicle?

The 2021 Mercedes-Benz GLA-Class competes with the BMW X1, Audi Q3, Lexus UX, and Volvo XC40. In terms of performance, the GLA offers a balanced driving experience, but the BMW X1 is often considered slightly more engaging. The Audi Q3 provides a similar level of luxury and technology.

Feature-wise, the GLA is well-equipped, but its infotainment system can be less intuitive than some rivals. Reliability is generally good, but the Lexus UX has a stronger track record. In terms of price, the GLA is competitive, but options can quickly increase the price.
