In the chilly month of December, my trusty 2013 Mercedes Benz S400 Hybrid abruptly stalled at a drive-thru, refusing to start. The car was promptly towed to a local Mercedes Dealership, where I was informed that it would cost me a hefty $480 just to pinpoint the issue.

After a week-long wait, the dealership diagnosed a faulty battery and presented me with an eye-watering estimate of $14,000 for a new one. This was hard for me to digest, considering the car had only clocked 57,898 miles and hadn’t given me any trouble before this incident.

Seeking a second opinion, I had the car towed to an independent Mercedes-Benz mechanic I relied on for about six years. Despite their unfamiliarity with my Hybrid model, they agreed to explore the possibility of reconditioning my battery.

Meanwhile, I began scouring the internet for a used battery, a search that led me to an enlightening series of YouTube videos on common issues with Mercedes Benz S400 Hybrids. Each video was a comprehensive trove of information, all thanks to YOUCANIC.

Inspired by the content, I contacted YOUCANIC directly to explain my predicament. To my surprise, the next day, I received a call from the person who appeared in the videos. I relayed the dealership’s diagnosis, at which point he requested the diagnostic codes. Despite my efforts, the dealership failed to provide these codes, a shocking lapse given the $480 diagnostic fee.

Determined, I had the car rescanned at the independent mechanic’s shop and sent all the relevant details and images to YOUCANIC. On Monday, I received an email diagnosing the problem as the Electronic Control Module, not the HYBRID battery, which was the dealer’s diagnosis. I learned that this module was responsible for charging the hybrid battery.

Following YOUCANIC’s advice, I sourced a refurbished module, complete with a one-year warranty, and bought a new regular car battery as suggested. After having the module installed, all the troubling codes vanished, and my car roared back to life, running as smoothly as ever. The total cost was a mere fraction of what the dealership had quoted, even if their diagnosis had been correct.

I am profoundly grateful to YOUCANIC for their invaluable assistance. Their integrity, expert knowledge, and genuine customer care make them prime examples of excellent business practices. I wholeheartedly endorse YOUCANIC as a superior, more affordable alternative to dealerships regarding hybrid vehicle issues.
