Panoramic roof: the glass can shatter on its own while driving

expensive

In the official complaint database the 2014 to 2018 model years account for 230 complaints, and 378 across the whole corpus.

Show the rest

The characteristic course of events: the panoramic roof glass shatters while driving, with no impact, with a loud bang. Across the whole group 108 complaints use the wording "exploded / shattered into pieces", 155 say it happened while driving, 38 specifically note that nothing struck the roof, and 43 complaints mention injury or cuts from the glass.

By measurement the affected group is primarily the W205 C-Class (2015 to 2017), plus the MFA platform GLA (X156) and CLA (C117) in the 2014 to 2015 model years.

There is no rattle beforehand and no warning. The traces of a replacement show on the seal and the bonding. The replacement is not cheap, and the broken glass falls into the cabin.

The complaint database is American, and the panoramic roof is more common there as an option. The phenomenon itself does not depend on the market.

What to check

  • Ask whether the panoramic roof glass has already been replaced: the traces show on the seal and the bonding
  • Look at the edge of the roof from outside and inside: cracks, chips, signs of earlier repair
  • Ask for the service history and any trace of an insurance claim (glass damage)

Information, not an expert opinion

We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.

  • A fault on the list does not mean the car you are looking at has it.
  • A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
  • You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
