2015 Mercedes-Benz GLA 250 body problems

Filed Aug 26, 2026 · Body, Suspension · PA

During an inspection, an authorized Mercedes-Benz dealership discovered severe corrosion and perforation, including holes, in the rear subframe of my 2015 Mercedes-Benz GLA. There were no warning lights or messages alerting us to the condition before it was discovered. The dealership confirmed that the subframe requires replacement and estimated the repair at approximately $6,000. The vehicle has approximately 140,000 miles. The rear subframe is a structural component that supports suspension components. Its advanced corrosion and perforation create concern that it could weaken or fail while the vehicle is being driven, potentially affecting vehicle stability and control. The vehicle and affected component are available for inspection upon request, and photographs of the corrosion and holes are available. Mercedes-Benz USA was notified of the problem but has not agreed to cover the repair. Mercedes-Benz has issued a 20-year/unlimited-mile extended warranty for corrosion with perforation of rear subframes on several other Mercedes-Benz models, but the GLA is not currently included. I am reporting this because the same type of premature structural subframe corrosion appears to be occurring in this vehicle and may present a safety defect affecting other GLA owners.

Mercedes repair shop inspected this car and stated that there is rear-subframe rusting and corrosion. Repair shop states that this is a safety issue. I took it into Mercedes dealer who stated that this VIN is not covered by a 20-year, unlimited-mile rear-subframe warranty (Feb–Mar 2023) for specific models (C/E/GLK/CLS/SLK/SLC/SL). Mercedes extended the warranty on the models where they saw the most repeat failures, in a way that addresses the worst cases (holes) while controlling scope and liability—not an admission of a universal defect across all lines (e.g., GLA), which is why my VIN isn’t in the program.

The contact owns a 2015 Mercedes-Benz GLA250. The contact stated that the sunroof failed to close completely as needed. Upon inspection, the contact discovered that a plastic part of the roof panel had detached. The vehicle was taken to an independent mechanic, who replaced the right and left roof guides, motor glass, and headliners. The contact related the failure to the federal safety agency Campaign Number: 23V854000 (Structure); however, the VIN was not included in the recall. The manufacturer was made aware of the failure. The failure mileage was approximately 120,000.

The panoramic sunroof will not open on one side rendering the sunroof unusable. this problem is happening often on this Mercedes model. Looks like Mercedes used plastic guide to move the sunroof back and forward and if you take a bump while driving with the sunroof on the tilted position it will break the plastic tracks rendering the sunroof unusable. this is a time-consuming fix because the interior of the car needs to come out to completely remove the sunroof and replace the damage part with the same original part that will break again under the same circumstances.

Mercedes no longer supports the sos ( tel-aid) system, so this system no longer works...each time you start the car, the sos inoperative warning light is on, and it blocks other safety features ( speedometer etc..). You have to reset the light each time you get in the car. Without the support of the system there is no emergency alert theft tracking ,airbag deployment sent to MB etc etc. Mercedes no longer services this feature, and this is one of the reasons we bought this car. It's a tremendous safety concern. Even though there are dealer bulletins about this, there is no fix. All these cars should be purchased back by MB. I'm uncomfortable driving a car that could be involved in a collision, and the car not notifying MB, or the police

Panoramic sunroof slider shoes failing, being cracked and stuck in the railing, causing a sunroof malfunction. The main concern of danger is that during closing the sunroof, with a lack of support glass bangs down coming in contact with some metal parts, risk of being shattered and cause injury to passengers. In my specific car, somehow all 4 shoe sliders failed on a car with less than 50,000 miles. While researching, the issue is raised by many other owners and appears to be a wide spread systemic flaw. https://www.glaowners.com/threads/shoe-on-rail-of-panoramic-sunroof-broke.26716/page-5

Sunroof shoes have deteriorated and panoramic roof has become loose off the rails. This is a highly disturbing erosion putting drivers and other vehicles on the road in danger. I have found hundreds of reported cases of the same issue with no recall in place.

Back door was ajar and there was no warning display to state the door was not closed completely. I was able to pull out of my driveway and the warning did not display until I was driving. Safety issue especially with small children in the back seat.
