Electrical System, vehicle Speed Control, forward Collision Avoidance

While driving on highways using cruise control and adaptive cruise control the vehicle decelerates without driver input. The system also misreads or fails to update speed limit signs causing incorrect cruise speeds and sudden speed changes. This behavior has occurred repeatedly during normal driving conditions and creates a risk of rear end collision from following traffic. The problem has been documented across multiple service visits. A repair attempt was made and I was informed that no repair is currently available. The issue recurred immediately after the repair attempt and remains unresolved. No consistent warning lights are displayed before or during the events. The vehicle is available for inspection upon request.

The car was designed too low. When parked at a supermarket, Publix in surfside Miami Beach, when ready to leave the parking bumper pulled at the front bumper and disconnected it partially. A north miami Mercedes Benz service department said this is not unusual as this car is very low. A claim was filed with progressive auto insurance [XXX] and an escalation case opened with Mercedes Benz customer service case number [XXX] asking that at least they cover the $1,000 insurance deductible.

The tire (Pirelli 255/35R21) on my 2023 Mercedes Benz 580V4 developed a bubble on its sidewall. This tire was just replaced February 16, 2024, and has under 8,000 miles on it. This is the fourth tire I have replaced due to bubbles on the sidewalls.

On [XXX] I had a blowout on the passenger front side of my vehicle. The vehicle was towed to Sugarland MB and a new Pirelli 255/35 R21 purchased. The blowout happened after I hit a bump (not pothole) in the road on [XXX] at [XXX] . My 2023 MB 580V had 9701 miles on it and had just had it's first "A" service with no defects noted in any of the tires. On [XXX] I noticed a bulge on the front driver's side tire. I took it into Sewell MB and they notice additional defects on another tire. I had to purchase one front driver side 255/35 R21 and a rear passenger side 285/30R 21. After leaving the dealership I filed a complaint with the NHTSA file #11622692 and called Pirelli to report the failures and make a formal complaint. I also called MB customer service and opened case #[XXX]. A representative from Pirelli contacted me on 10/31/2024 @ 11:00am and basically stated the issue with multiple failures of these 21" tires across the US is a MB problem and not Pirelli's. As of this followup compl...
