2020 GLE owners — turn signal triggering wipers / “Wiper Malfunction” / wipers turning on by themselves?
We have two separate 2020 Mercedes GLEs in our family that have developed almost the exact same unusual problem.
It initially started with the windshield wipers sometimes activating when the turn signal was used, along with a “Wiper Malfunction” warning.
On one of the cars, the problem has now progressed to the wipers coming on by themselves. I drove it today and the first hour was completely normal, but during the last 30 minutes the wipers ran almost continuously without being intentionally turned on.
I’ve found a few other GLE owners online describing very similar symptoms, so I’m trying to understand how widespread this may be.
If you’ve experienced this on a GLE — or another Mercedes model — I’d really appreciate hearing:
Model and year
What the wipers did
Whether it started when using the turn signal
Whether you received a “Wiper Malfunction” warning
What Mercedes diagnosed
What part was replaced
Whether the repair fixed it
Approximate repair cost
Any fault codes or part numbers you have
Even if you eventually sold or traded the vehicle because of the problem, I’d still like to hear about your experience.
Thx
