- #11631897December 20, 2024ELECTRICAL SYSTEM, ENGINE, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Check engine light came on few occasions. Took to the dealer and told it’s just a false alarm no problems. On the night of sept 12th 2024, I’m my way home I lost the ac cooling all of a sudden. I was only 5 mts from home. Once inside my garage I saw to my horror some smoke coming from under yhe hood. Upon opening saw some charred wires and some wire smoldering and smoke was coming out of it. Scared for my family I parked my car outside overnite and called the dealer. They had the car towed away the next day. Got my car back on 6 th of November 2024, with a laundry list of problems and issues, that they had supposedly fixed. Three or four various engine wiring harnesses were replaced, due to charring or melting, probably due to the heat. The engine and transmission were lifted off to fix all the wires and what not. I have all the invoices. And video and pictures of some wires and smoke. They don’t have an explanation for this. The recent recall about ecu maybe suggests the overheating of engine and causing the wires to burn out and some wires started burning almost causing fire if not caught in time. Called Mbusa and they didn’t show any concern. But one week after this incident they issued that ecu engine heating warning. Off course there is no repair for that. This is a fire hazard waiting to happen.

- #11625649November 16, 2024SERVICE BRAKES
Brakes seize when wet. That is, after a car wash or following exposure to rain, the accelerator must be pressed with abnormally greater pressure to get car moving from parked position. Loud, screeching sound emanates when brake releases. This malady continues severally. Resting lightly on brake pedal to dry out turning brake rotors, does not help. Eventually, problem disappears until the next wet episode. -Per Mercedes Authorized Dealer, there is no fix; problem is common to Mercedes 223 series. -Risk of collision exists in both modes, Drive as well as Reverse. This, due to sudden jump forward or rearward under brake-seize conditions. -Issue is ongoing, not a single incident. Remains unresolved. [At age [XXX] , I have over [XXX] driving experience. The above is an abnormal-with-risk, issue.] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

- #11622692October 30, 2024TIRES, TIRES:SIDEWALL
I had 9985 miles on my 2023 Mercedes S580V when the front passenger tire experienced a blowout earlier this year. The tire failed right after I had my first A service which did not show an issue with tires. Today is 10/30/2024 and I have 13978 miles on my vehicle. The driver side front tire Pirelli 255/35-R21/98Y has a bubble on the side wall. I took it to my dealership and they discovered that the rear passenger side Pirelli 285/30-R21/100Y has a bubble as well. I am having both tires replaced today.

- #11614618September 14, 2024FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
The car slams on the brakes for no reason. phantom braking. i have been tailgated because cars behind me - particularly on tye highway - think i’ve brake checked them (but it was the care slamming on the brakes). the door handles don’t open/deploy reliably. sometimes they work, sometimes they don’t. the touch screens are incredibly dangerous - especially when the system freezes or doesn’t work properly - which is often. there are almost no physical buttons. the system software & touchscreens are VERY glitchy and often doesn’t function properly. touch-sensitive buttons on the steering wheel get activated just from me driving. functions turn on and off just because my hands in on the steering wheel. it’s dangerous. the car had 7 flat tires in 1 year. it’s too heavy for the 21” low profile tires. MBUSA has been made aware of the multitude of problems. The car is constantly at the dealership for warranty repairs. It's a lemon, but MBUSA won’t do anything about it. not until someone gets killed. MBUSA blows me off with every interaction and complaint i make about the quality problems with this car. They don’t care.

- #11610863August 26, 2024FUEL/PROPULSION SYSTEM, ENGINE, ELECTRICAL SYSTEM
I purchased this vehicle in July 2020. I did a through check for recalls, warranty problems and could not identify any with this vehicle. From the get go the check engine light would come on. I checked the codes and they indicated an "electrical fault on bank 1, oxygen sensor 1. I replaced the wiring harness on that sensor as well as the sensor. From then until now the car would code weekly about the same issue. Eventually I started using a catalytic converter cleaner (it cleans off sulfur deposits) in an attempt to solve the issue. It would work for a couple of tanks of gas and then continuing coding. I asked MB on numerous occasions about what the issue was. They all said they had no idea. It looks to me like they knew what the issue was, but kept it to themselves. Several weeks ago I received a letter in the mail(not dated by postmark) but the letter was dated August, 2023. The letter outlined an issue with the catalytic converter system identifying my vehicle by vin. The same problem I have had all along. The letter came at a time when the car codes almost daily with the same issue as always, ONLY NOW THE VEHICLE STALLS occasionally while waiting at stop lights. I said great. I called to get an appointment to fix the issue only to be told that the fix window had passed. I told them that I just got the letter. They told me that the fix expired in December 2023. I called MB hotline at 1-800-367-6372 to see what was up. They said they would get back to me in 3 days. It's been a week so I called again and they advised me they can't help. It's an issue for the 2011, 2012, 2013, and 2014 MB S550 W221. Why is this not a recall and why won't they fix it. It's an expensive repair. They sent me the letter and said it was expired 6 months before I received the letter. Can you help?

I was driving on highway on 7/26 Friday in exit lane when my panoramic sunroof exploded and shattered on me while driving. It sounded like a shogun. Some of the glass came in on me and other part flew out vehicle causing paint damage. I inspected car there was no impact from anything (ie rock, branch etc). It was a clear sunny dry day no vehicles in front that would have kicked up an object no impact whatsoever. I made to my house 3 miles away and there is no impact after inspection i have insurance adjuster coming Monday 7/29. I checked internet and have heard of others stating same experience. I looked at NHTSA site and my car doesn’t look like it was part of a national recall notice. Very frightening situation a more inexperienced driver may have not handled the situation.

I have the 2022 S 500 with 21 inch mag spoke rims with Pirelli 255/35R21 tires on it which comes stock from Mercedes Benz. I have now been in almost 15 tires repair claims and 3 rim replacements because of how poorly Mercedes designed the rims then put a tire soon the car that cannot handle the weight of the car. I hit a pot hole and my whole tire blew out almost causing a severe crash. this is again the almost 15th time this has happened. I took the car to Mercedes Beverly Hills and the service advisors say that now there is $16,000 dollars in damages on the car fro the constant impact it has taken from the rims being poorly designed on the car. I have asked many times to replace the tire brand to a better and thicker tire. but Mercedes will not allow that and demands I pay over 16k in damages to fix suspensions and the drive unit issues.
