There are 3 owner-reported electrical system complaints for the 2011 Mercedes-Benz GL-Classin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
We smelled smoke from under the passenger seat. We had the car in for a recall and service recently and didn’t understand what was happening. Our three Children smelled the smoke too. Everyone exited the car and it burst into flames.
Intermittently car does not engage when key fob is inserted into eis (electric ignition switch) and turned. No dash lights turn on, car does not start. Car has turned off while driving. Car has remained running when key was removed. Key will lock and unlock doors and open hatch.
THE ELECTRONIC IGNITION SWITCH EITHER WON'T START THE ENGINE OR WILL FINALLY START AFTER A LONG DELAY OR AFTER REPEATED ATTEMPTS ARE MADE TO TURN THE KEY AND START THE ENGINE USING EITHER OF THE TWO ELECTRONIC KEYS. THE CAR HAS FAILED TO START CAUSING MY WIFE TO BE STRANDED ON NUMEROUS OCCASIONS AND POSES A SERIOUS SAFETY PROBLEM. MERCEDES HAS A SERVICE CAMPAIGN #2013040001 THAT APPLIES TO THIS VERY VEHICLE TO CORRECT THIS VERY PROBLEM BUT I WAS TOLD THAT MY VIN NUMBER HAS NOT BEEN INCLUDED FOR THIS CAMPAIGN. THIS IS CLEARLY A DEFECTIVE ELECTRONIC IGNITION SWITCH (EIS) PROBLEM WITH MOST OF THESE 2011 - 2012 VEHICLES AS ANY GOOGLE SEARCH WILL REVEAL.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
