2015 Mercedes-Benz CLA-Class Body & Structure Problems

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 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.

On May 10th while driving on I-35 Texas highway, the panoramic sunroof of our 2015 Mercedes Benz CLA 250 shattered the whole panoramic sunroof, my daughter describes as some shot at the car. there was particles of glass on the driver side and passenger, very dangerous situation. She pulled over into a gas station and noticed there were pieces of glass shattered all over the interior some. The second incident happed about 2 weeks ago on the recalled part, while driving the panoramic sunroof stationary roof panel located between the windshield and the panoramic sunroof part came off while driving and hit the behind, luckily no one was harmed during the incident. I took the recalled letter to the local Mercedes in San Antonio refusing to fix the recalled part and apparently the part is not available and there is no date as to when is going to be available, in the meanwhile we can't drive the car. Also it took almost 4 months to replace the panoramic roof, I will file another complaint about the panoramic roof, apparently this is a common thing with this model CLA250.

On May 10th while driving on I-35 Texas highway, San Antonio Texas, the panoramic sunroof of our 2015 Mercedes Benz CLA 250 completely shattered while wife driving and daughter as a passenger, they heard a big bang and suddenly pieces of shattered glass fell all over the interior some of the glass hitting my wife and daughter in the face, they immediately pulled over to evaluate the situation. This could have caused an accident or significant injury. She had SAPD meet her at a gas station as she thought someone has shot at the glass, but officer confirmed that indeed the panoramic sunroof completely shattered. We tried to fix the panoramic roof and both Mercedes dealerships in San Antonio and Boerne Texas refused to repair the panoramic sunroof, we had to file a claim with our insurance and take the car to a collision center. The collision center stated that the sunroof was on back order from Mercedes Corp and had no timeline as to when the part would be available. Due to the car was not safe to drive and timeline on the parts, our insurance offered to total the car, but the car is almost new, low miles and in perfect mechanical condition so we declined. We received a call 4 months later that the car was fixed and the panoramic roof was installed.

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.

Incident on 10/18/21, while coasting into a parking space, my car suddenly accelerated and smashed into a concrete wall. Damage was extensive and car was determined a loss. Service was maintained throughout ownership. There was no warning, no lights, messages, no ABS brakes. Airbag did not deploy. Extensive seatbelt bruising. I'm upset car was a loss but I would never feel safe driving it. It was as if someone else had taken over control and I was powerless to alter the situation.
