New GLC 300 – software glitches! (requesting owners to get the s/w updated practively)
A week ago on a Sunday morning, I was on a long drive with family, we had parked the car for about 30 minutes for breakfast on the highway. After finishing breakfast, I unlocked the car and got in and heard a long beeping sound, and then everything went blank (nothing on MBUX, nothing on the driver dash, etc). The car won’t start either, I got worried as I was about 100 Km away from Bangalore, so I called up the Akhsaya Mortors Hosur Road branch Service Manager, he immediately picked up my call and tried to assist with a few things, but nothing worked. He called back along with a senior tech on a whats app video call and asked me to try a few more things, nothing worked at that time also. He told me he would likely have to send a tech team to my location and check out the car, After about 10 to 15 minutes later, I opened the car to try one more time and magically everything started working and the car re-started!
The service manager asked me to bring the car to the service center, and I returned to the service center and handed over the car; it was returned to me a few hours later after updating some of the s/w components (details below).
First of all I am thankful to the Mercedes Benz Service Center team at Akshaya Motors for their prompt response and that too on a Sunday!
But the question though is I bought a premium luxury car for peace of mind and top quality! I shudder to think about a scenario if I was stuck in a remote area on a late evening or night along with family and the car refused to start.
Concerned about the quality of the brand-new car manufactured in Jan 2024, I raised the issue with Mercedes, and they shared the following details about the s/w updates.
“In this context we are given to understand that your vehicle was reported at the authorized dealership M/s. Akshaya Motors, Hosur Road for the concern of vehicle not starting. Further, we wish to apprise you that the dealership conducted a comprehensive inspection, diagnosis of your vehicle and it was determined that software updating is required for EZS Central Gateway & Door Control Unit to address the concern. We wish to inform you that all necessary remediations have been completed and your three-pointed star was delivered back to your good hands, post affirming its optimal performance and road worthy condition. We request you to drive your three-pointed star with full passion.”
I hope the problem is really fixed and similar software glitches will not happen again. I am really surprised that these software updates were not applied when the car was delivered to me and not even in the first service ?
There is an active s/w update directive to all dealers from Mercedes Benz worldwide. Please see below thread, these type of s/w glitches for Mercedes Benz GLC in particular is widely reported in the US and rest of the world (I really wish I saw these before my purchase decision).
