GLE Mirror Heating Failure

Has anyone else experienced mirror heating issues? My 2022 Mercedes GLE with a diesel engine has defective mirror heating at only 25877 km. Neither side works. The diagnostic throws an error, likely a cable or plug issue. I'm thinking this impacts vehicle safety, especially for winter driving. Has anyone experienced this before I consider a mirror replacement? Temperature control is suffering

Summary of the thread

A 2022 Mercedes GLE owner reported a failure in the mirror heating system, with neither side functioning and a diagnostic error suggesting a cable or plug issue. This problem was considered a safety concern, especially for winter driving. After consulting with a technician, the issue was traced to a faulty connector, which was re-pinned, resolving the problem without needing a mirror replacement.

I encountered a somewhat comparable problem on my old Volvo. The rearview mirror heating was completely non-functional! I'd advise checking the fuses first, though I am uncertain if this will resolve your issue. It appears from your description that you have already investigated the issue thoroughly. I'm not sure, but perhaps the mirror replacement could be a solution.

Thanks for the input. Which fuse was it specifically on your Volvo, and where was it located? I'm also curious if your Volvo threw an error code like my GLE did, or was it just a dead mirror? Any further details you can recall?

Regrettably, I am unable to recall the precise fuse number or its exact location on my Volvo. My apologies! What I do remember is that, similarly to your situation, an error code was indeed present. Given that your Mercedes is still relatively new, perhaps it would be prudent to consult with a qualified technician. Replacing components could be expensive, and I am not sure if it is the correct solution.

Appreciate the advice. I took it to the shop. Turns out, it was indeed a faulty connector as suspected. They re-pinned it, cleared the code, and all good now. Cost me 95€. Glad I didn't jump to mirror replacement!
