The 2019 Mercedes-Benz GLA represents a blend of luxury and practicality in the compact SUV segment. For owners and prospective buyers in the English-speaking market, understanding the maintenance requirements and reliability aspects of this vehicle is crucial. Mercedes-Benz, historically renowned for its engineering and robust vehicles, has seen shifts in its approach to servicing over the decades. To truly appreciate the maintenance needs of your 2019 GLA, it’s helpful to consider the evolution of Mercedes-Benz service philosophy.
A Look Back at Classic Mercedes-Benz Maintenance
In the past, Mercedes-Benz maintenance was synonymous with meticulous care and preventative measures. Going back to the 1980s, the approach was deeply rooted in engineering principles, prioritizing vehicle longevity and reliability above all else. Scheduled maintenance sessions were not just about oil changes; they were comprehensive inspections and adjustments designed to preemptively address potential issues.
Imagine a two-hour service appointment where a technician methodically worked through a detailed checklist. This wasn’t just about ticking boxes; it was about ensuring every system functioned optimally. This thoroughness included:
- Electrical System Checks: Every dashboard control and indicator light was tested for functionality. Nighttime illumination bulbs in the dash were also inspected.
- Body Panel Alignment and Lubrication: Panel gaps were checked and aligned, hinges were lubricated, and the hood and trunk heights were adjusted for perfect closure.
- Baseline Alignment and Headlight Geometry: Ensuring the car tracked straight and the headlights were correctly aimed for safety and optimal visibility.
- Drain and Rail Maintenance: Windshield cowl and sunroof drains were cleaned, sunroof rails lubricated, and even rain gutters on the roof were checked for blockages. Trunk drain plugs, especially in models like the W126 with rubber plugs, were inspected to prevent water accumulation.
- Washer Nozzle Adjustment and Fluid Top-Offs: Windshield, rear glass, and headlight washer nozzles were precisely adjusted. All fluids were refilled using OEM (Original Equipment Manufacturer) specifications.
- Wiper and Lighting System Synchronization: Wiper travel and parking positions were verified, including headlight wipers operating in sync. In some eras, headlight bulbs were even on a scheduled replacement, not just replaced when they burned out.
- Chassis Lubrication: Potentially involving grease gun fittings, this ensured smooth operation and prevented wear in key chassis components.
- Tire Management: Tire wear, condition, and spare tire pressure were meticulously checked. Wheel rotation was performed, and wheel bolts were tightened to the precise Mercedes torque specification – crucial for preventing issues, especially with models like the W126 with long wheel bolts.
- Suspension Height Measurement: Height at each wheel well was measured to assess the condition of suspension springs.
- Exhaust and Brake System Inspections: Comprehensive checks of these critical safety systems.
- First Aid Kit Servicing: Medical supplies in the car’s first aid kit were replaced due to expiration, ensuring readiness in emergencies.
- Tool and Spare Wheel Kit Inventory: Completeness of the tool and spare wheel kit was verified, and missing items were replaced.
- Interior Functionality Checks: Seat belt retractors, headrest operation, and rear seat folding mechanisms were all inspected.
- Specialized Lubrication: Telescopic radio antennas and key lock mechanisms for the trunk and doors were lubricated with specialized graphite grease.
- Filter Replacements: Beyond the usual air and oil filters, items like power steering and fuel filters were also part of the routine maintenance.
- Shock Absorber Assessment: Condition of suspension shocks was evaluated.
- Lighting and Locking Systems: License plate bulbs and pneumatic door locks were checked.
- Mirror Operation: Full travel of rearview mirrors was tested to ensure motor functionality.
This exhaustive list highlights a philosophy of preventative maintenance and meticulous attention to detail. While customers were charged for this labor-intensive service, they witnessed technicians actively working on their vehicles for extended periods, providing a sense of value and confidence in the reliability of their Mercedes-Benz.
The Evolution to Service A and B and Modern Maintenance
Over time, Mercedes-Benz transitioned away from this extensive maintenance schedule. Many of these detailed checks and adjustments were removed from the standard service protocols. However, the cost of service, particularly for “Service A” and “Service B,” did not proportionally decrease. This shift has led to a perception that modern Mercedes-Benz services might be less comprehensive while still carrying a premium price tag.
For owners of a 2019 Mercedes-Benz GLA, understanding this historical context is important. While the GLA benefits from modern engineering and technology, the standard Service A and B schedules might not encompass the same depth of preventative maintenance as in previous eras. It’s crucial for GLA owners to be proactive about understanding their specific maintenance schedule and what each service entails.
Unlocking Hidden Features with Xentry: Customization for Your 2019 GLA
Interestingly, Mercedes-Benz vehicles, including the 2019 GLA, possess customizable features accessible through the Xentry diagnostic system, often without the owner’s explicit knowledge. These “User Author data” settings allow technicians to personalize certain aspects of the car based on customer preference. Examples include:
- HVAC Fan Speed Display: In the HVAC controls module, the fan speed display, which typically appears briefly and then disappears, can be configured to remain visible continuously upon customer request.
- Shifter Console Lighting: For models like the GLA45 (and potentially applicable to the broader 2019 GLA range), the intensity of the illuminated PRND markings on the shifter console can be adjusted for both day and night driving. These lights are factory set at an intensity factor of 1, but can be increased up to 10 and set differently for day and night.
These examples suggest that Mercedes-Benz engineers designed a degree of personalization into their vehicles, allowing for adjustments to enhance the user experience. However, these options are not always widely advertised to customers and often require dealer intervention and the use of the Xentry system to activate.
Conclusion: Informed Maintenance for Your 2019 Mercedes-Benz GLA
Owning a 2019 Mercedes-Benz GLA offers a blend of luxury, performance, and practicality. To ensure its longevity and reliability, understanding its maintenance needs is paramount. While modern Service A and B provide essential checks, appreciating the historical depth of Mercedes-Benz maintenance can inform a more proactive approach to car care.
GLA owners should:
- Familiarize themselves with the specific maintenance schedule for the 2019 model year.
- Inquire with their dealer about the details of Service A and B, and what is specifically included.
- Don’t hesitate to ask about potential customization options available through Xentry, such as those related to display settings and interior lighting.
By taking an informed and proactive approach to maintenance, owners can ensure their 2019 Mercedes-Benz GLA remains a reliable and enjoyable vehicle for years to come.
