Hello,
I have a GLC that I purchased in Mar 2016.
For the last 3-4 months, I have been consistently getting warning messages on the dash, in the phone app and through email that the battery charge is critical and it requires charging.
No matter how far I drive, sometime after I park the car, i will receive these warning messages.
This Saturday I drove the car around for 3 hrs, afterwards i checked the battery with a multimeter, it showed 12.06v, I then checked it again the next day, 20hrs later it showed 11.9v.
Today the car is in the Mercedes garage for a 2nd time to check the battery, I just received a call from the workshop to say all fine, nothing wrong with the battery... It just needs charging... The issue is your driving style... Upon questioning I am told the diagnostic equipment reports no errors.... After more questioning I am told that the battery has indeed changed characteristics as it is getting older, but there are no errors with diagnostic equipment, etc,etc, after more discussion I've asked for the service manager to call me... Alas I know what will happen, Mercedes will claim no issue and will not fix what ever is causing the problem, be it the battery, the alternator or something draining the battery.
Now my point is, I have not changed my driver style for the whole period of the GLC ownership, Mercedes however blame my driving style. However my driving style was perfectly fine for 2 yrs without issue. Therefore logic dictates that the charging characteristics are not sufficient after 2yrs of aging components to charge the battery enough to support my driving style.
In my mind Mercedes should be replacing parts to allow the charging characteristics to support my style of driving.
How do I get Mercedes to do something about this problem?
Regards
Richard.
