Purchasing a new vehicle is always an exciting experience, especially when upgrading within a trusted brand. As a loyal Mercedes-Benz customer and now a three-time GLA owner, transitioning to the 2024 Mercedes-benz Gla250 4matic was initially anticipated with enthusiasm. Having previously leased the 2018 and 2021 GLA models without significant issues, the decision to buy the 2024 version seemed natural. However, early experiences with this latest model have revealed some concerning problems that potential buyers should be aware of.
Shortly after acquiring the 2024 GLA250 4MATIC in late February, a “Check Engine” light illuminated, signaling the first in a series of unexpected setbacks. The issue was diagnosed as a defective thermostat, requiring the vehicle to be at the dealership for several weeks. During this repair period, a loaner 2024 GLA was provided, which, surprisingly, exhibited some of the same issues as my own vehicle. This parallel experience suggests that these problems may not be isolated incidents but rather more widespread concerns affecting the 2024 GLA model range.
Common Issues Encountered with the 2024 Mercedes-Benz GLA250 4MATIC
Several recurring issues have become apparent in both my personal 2024 Mercedes-Benz GLA250 4MATIC and the loaner vehicle, raising questions about the overall quality control of this model year.
Trunk Clunking or Shifting Noise
One of the most noticeable and perturbing issues is a distinct clunking or shifting noise emanating from the trunk area. This noise is particularly evident when braking at slow speeds or during parking maneuvers. Both my purchased GLA250 4MATIC and the loaner vehicle exhibited this problem. The sound, described as if something heavy is rolling around in the trunk, is not only distracting but also detracts significantly from the expected premium driving experience of a Mercedes-Benz. For some owners, like myself, this noise is so bothersome that it necessitates turning up the radio to mask it. The exact cause of this trunk noise remains unclear, but its presence in multiple vehicles indicates a potential design or manufacturing flaw that Mercedes-Benz needs to address.
Gear Shift Motor Noises
Another area of concern is the noise from the gear shift motor, particularly noticeable during gear changes from D1 to D6 on secondary roads. While the expectation is for smooth and subtle gear transitions in a luxury vehicle, the 2024 GLA250 4MATIC sometimes exhibits audible noises during these shifts. While not consistently present or as intrusive as the trunk noise, it does suggest a lack of refinement in the drivetrain operation, which is unexpected in a vehicle of this class.
Intermittent Wireless Phone Charging
The wireless phone charging system in the 2024 GLA250 4MATIC has proven to be unreliable. The system frequently cycles on and off, resulting in inconsistent charging. Achieving a stable charging connection requires precise phone positioning, which is both inconvenient and frustrating. To circumvent this faulty wireless charger, resorting to a traditional plug-in charger becomes necessary, negating the convenience that wireless charging is intended to provide. This issue highlights a functional flaw in the vehicle’s technology interface.
Apple CarPlay Connectivity Problems
Intermittent issues with Apple CarPlay connectivity have also surfaced in the 2024 GLA250 4MATIC. Unlike previous GLA models (2018 and 2021) where Apple CarPlay functioned seamlessly, the 2024 model experiences unreliable connections, particularly when using navigation. The sporadic nature of these connectivity problems is especially problematic when relying on Apple CarPlay for directions in unfamiliar areas. While Bluetooth connectivity is available, the unreliability of the system suggests a regression in technology integration compared to earlier models. A more dependable solution, even if it means reverting to a plug-in option for CarPlay, would be preferable for consistent navigation and infotainment access.
Overly Sensitive Anti-Collision System
The anti-collision system, intended to enhance safety, sometimes behaves erratically in the 2024 GLA250 4MATIC. Instances of unwarranted emergency braking and loud beeping are frequent, even in non-critical situations, such as exiting a parking garage or reversing into a driveway with no obstructions. These false alarms and abrupt stops, often accompanied by dramatic screeching and jolting, are not only unnerving but also undermine driver confidence in the system. The system’s oversensitivity and lack of accurate threat assessment suggest a need for calibration refinement to prevent unnecessary and jarring interventions.
Wiper and Rain Sensor Unreliability
Issues extend to the wiper system as well. On occasion, the rear wiper has failed to operate. Furthermore, the rain sensor’s sensitivity is questionable, often failing to activate even in light drizzle. This aligns with experiences in previous GLA models, suggesting a persistent issue across different model years. The unreliability of these basic functions detracts from the vehicle’s overall practicality and convenience in varying weather conditions.
Reversing Issues with Ground Obstacles
Finally, the 2024 GLA250 4MATIC has exhibited problems when reversing over even small objects on the ground. Instead of smoothly maneuvering, the vehicle can jerk or hesitate, suggesting an issue with the sensors or drivetrain response when encountering minor obstacles during reverse movement. This behavior can be particularly concerning in everyday driving scenarios where small debris or uneven surfaces are common.
Conclusion: Rethinking the 2024 Mercedes-Benz GLA250 4MATIC Experience
While the initial appeal of the 2024 Mercedes-Benz GLA250 4MATIC is undeniable, these early experiences highlight several significant issues that detract from the ownership experience. From unsettling noises to unreliable technology and overly sensitive safety systems, these problems raise concerns about the vehicle’s overall quality and reliability. Potential buyers should be keenly aware of these reported issues and consider whether these shortcomings align with their expectations for a premium compact SUV. Further investigation and resolution from Mercedes-Benz are essential to ensure the 2024 GLA250 4MATIC lives up to the brand’s reputation for excellence.
