2017 Mercedes-Benz E300 electrical problems

The Starting Current Limiter Recall (the federal safety agency Campaign 16V831000 / 17V114000): If your E-Class failed to start or struggled to crank initially, a defective starting current limiter can severely overheat the electrical lines to the starter, causing nearby components-including the battery assembly and main wiring—to melt and smoke. The above is exactly what happened. I was sitting at a red light and the car shut off and I tried to start it again and smoke started coming out of the right air vent in front of the battery. The wires to the battery were destroyed and part of the battery was melted. This is a certified pre-owned 2017 Mercedes E-300 4-matic. I just had the 100k mile maintenance done 2 months ago. The car is in perfect condition. New battery installed August 2025

My car is not accelerating when I shift into drive or reverse. It says “reversing not possile-service required” error. Out the blue. There is a known recall on these model cars but Mercedes benz is saying its vin specific and mine is not covered even though I am experiencing the exact same issue. Recall date- 2017-02-07 Recall no. 17V078000

I am writing to formally lodge a complaint regarding serious and repeated issues with my 2017 Mercedes-Benz E300, purchased and serviced exclusively by authorized Mercedes-Benz dealerships. 1. Repeated OEM Run-Flat Tire Failures Within the past two years, I have been forced to replace nine OEM run-flat tires, including:    •   3 replacements at Mercedes-Benz of Tysons Corner, VA    •   2 replacements at Goodyear Tires, Cattlemen Rd., Sarasota, FL    •   4 additional replacements at certified service centers These failures occur under normal driving conditions, often without visible punctures or road hazards, and at safe speeds. Each tire replacement costs approximately $550, plus towing, diagnostic fees, and rental car costs. The financial and safety burdens are substantial, and this level of tire failure is not normal for any vehicle—particularly a low-mileage, luxury sedan. 2. Electrical/Dashboard Recording Malfunction My dashboard service history fails to record service visits, even when performed at Mercedes-Benz dealerships. This is deeply concerning as it compromises vehicle resale value, warranty tracking, and transparency of maintenance records. Despite multiple visits and attempts by service centers, the issue persists without resolution. 3. Financial Impact and Brand Reputation The total cost of repeated tire replacements and unresolved electrical issues has reached several thousand dollars, despite my vehicle having relatively low mileage and receiving all recommended service at authorized dealers. This experience is completely inconsistent with the quality and reliability promised by the Mercedes-Benz brand. I am requesting the following:    •   Full investigation into the defect rate of OEM run-flat tires on the 2017 E-Class models    •   Immediate inspection and repair of the dashboard/electrical recording issue at no cost to me    •   Reimbursement for tire-related costs and associated expenses incurred due to repeated failures.

When using Map apps through CarPlay, I’ve noticed two consistent problems: Inaccurate Vehicle Speed: The carplay speedometor does not match the the actual speedometer of the vehicle, which seems always 1.6 times higher than the actual(seems to be the metric confusion from mph to kmh). GPS Drift: The location shown on the map is frequently ahead of my actual position, which causes navigation directions (especially turns and exits) to be slightly mistimed. However, when the speedometer is correct, the GPS drift issue would disappear automatically. So I assume that these two issues are correlated. These issues can be confusing and potentially unsafe while driving. I’ve tested other navigation apps on CarPlay and found they do exhibit the same behavior, so I suspect the issue may be general to Mercedes E300 and probably other vehicles. I did a bit of research and found it to be a common issue of Mercedes E300 2017. Please see attached link for the threads from MB forum. https://mbworld.org/forums/gls-class-x167/843643-wrong-speed-limit-detected.html Thank you for your assistance, and I look forward to your reply. Best regards

Battery being drained, the car does not start, water inside the vehicle on the floor at the drivers side

The entire driver instrument panel screen went blank, after going blank and coming back on a few times while driving. This is EXTREMELY dangerous. Now, the driver cannot see the speed, odo, fuel gauge, indicators or anything at all. I hope you please investigate and initiate a campaign and get this resolved from Mercedes.

Suddenly , the trunk stopped closing completely. Noted a significant gap in the trunk to the quarter panel due to the pull down function / soft close not working. Trunk is now slightly open, which could be an issue with water ingress with many electrical components in the trunk compartment.
