7 Equipment problem of the 2015 Mercedes Benz S550

Failure Date: 10/17/2023

I am writing to report an incident that occurred on oct 17 2023 involving my 2015 Mercedes Benz S550, where the front portion of the two-part sunroof spontaneously exploded while I was driving down the highway. On the aforementioned date, at approximately 5 pm, I was traveling down beltway 8 in houston in my Mercedes Benz S550 along with a pack of cars. Suddenly, without any warning signs or external impact, my vehicle experienced a violent shaking accompanied by an extremely loud popping sound, reminiscent of a gunshot. The intensity of the event startled me, and I quickly maneuvered my car to safety while other drivers also reacted to the sudden disturbance on the road. Once I pulled over and inspected the damage, I was horrified to discover that the front portion of the two-part sunroof had completely shattered, leaving a significant hole and glass fragments both inside and outside the vehicle. The explosion occurred on the beltway, before the kirby exit. Fortunately, I escaped any injury as the glass fragments were ejected upwards due to the force of the explosion. It is important to highlight the potential devastation that could have occurred had I kept the screen under the sunroof rolled in, as is my usual practice. Considering the size and force of the explosion, it is reasonable to imagine that if the glass had come pouring down onto my head and body, it could have caused severe injuries, including lacerations, contusions, and possibly even more serious harm. In light of this incident, I am deeply concerned about the safety implications for myself and other vehicle owners who may encounter similar issues with the sunroof in their Mercedes Benz S550 or other models. It is crucial that this matter be thoroughly investigated to determine the underlying cause and prevent any potential risks or harm to future drivers.

10 Equipment problem of the 2016 Mercedes Benz S550

Failure Date: 02/26/2022

On Feb 26, 2022 between the hours of 4:00 am and 5:15 am the sunroof on my 2016 S550 Mercedes Benz shatter for no cause or reasons while driving on the main highway. When the loud bang accrued while driving I immediately pulled the car over to exam the issue and I noticed the sunroof glass had shattered. I was able to drive the S550 Mercedes Benz to my residence. However, this sunroof shattering could have a cause major issue if the lower cover to my sunroof was open. I would strong recommend Mercedes Benz reach out to the glass manufacture concerning this safety issue with defective glass (shattering glass sunroof for no cause or reasons).

The gear selector on the steering wheel of the Mercedes Benz has a park button on it when you change the car from gear to park you press that button. That part button has stopped working.

Takata recall. I was driving on the highway on my way to phoenix az to drop off my mom and grandma when suddenly the sunroof exploded. It sounded like a gun shot.

21 Equipment problem of the 2011 Mercedes Benz S550

Failure Date: 06/14/2017

Shifting lever is up for reverse, center for park, down for forward. All other transmissions you push up for park. After driving all other cars, even prior mercedes if you exit the car you push the transmission lever to up for park even with the engine running you push the lever up for park. This becomes a habit, a reflexive action but if you do this in this mercedes you go into reverse. What happened to me is I started the car in my garage and forgot something so I hopped out while reaching for the shift lever and pushed up for park, but it wasn't park, it was reverse and my car started backward with me only partially in the car. I barely made it back in before I wiped out my drivers door on the garage wall as the car exited the garage. I came within a whisper of getting smashed between the car door and the garage. Damage, about $7,000 but I avoided getting killed. Now, you may say that it is my fault for not shifting properly but why would mercedes go away from what has been the practice for many, many years? much of driving is doing what you have been conditioned to do, much of it is reflexive and that should be considered in design for safety. I wrote to mercedes about this and told them that this is a safety issue. I asked them for reimbursement for my repair but I don't expect they will comply.

22 Equipment problem of the 2007 Mercedes Benz S550

Failure Date: 09/23/2016

Takata recall-I took my vehicle into park place mercedes of arlington in dallas, TX to get a diagnostic on why my panoramic sunroof would not open. I thought it could be repaired but service tech told me that the whole roof would have to be replaced. I feel like these cars are too expensive for parts not to be able to be repaired and have to be replaced. The shade goes back and forth, just the glass won't open, I don't understand why the whole roof has to be replaced. It sounds like an internal defect and I don't feel like I should have to pay for a whole new roof because of one part of it won't open up. Mercedes needs to look into a recall for this situation on panoramic roofs.

23 Equipment problem of the 2009 Mercedes Benz S550

25 Equipment problem of the 2007 Mercedes Benz S550

Failure Date: 10/18/2015

While driving on a very populated interstate may car lost power and was stuck in one gear and I nearly got hit from behind by another vehicle. Mercedes told me that my conductor plate failed and this was the cause of my transmission slipping from one gear to a very low gear. In my opinion this is very dangerous for our roads and I think that they should be responsible and make this problem go away before someone or multiple people get hurt.

28 Equipment problem of the 2007 Mercedes Benz S550

Failure Date: 11/05/2014

Worn timing sprocket and balance shaft was defective when I purchase the vehicle in 2011. Mercedes benz knew about this defective part and did not inform me. The vehicle had 46000 miles on it at the time. If I was inform about this problem I wouldn't have bought it. I believe this is a violation of the consumer protection act.

29 Equipment problem of the 2007 Mercedes Benz S550

Failure Date: 08/22/2014

2007 S550, 7-speed automatic transmission, 57,000 miles. Started about 6-8 months ago. Experiencing very rough jolting type shifting, most commonly occurs after being parked on an incline or decline. Occurs when driving up or down an incline. Also, occurs on the freeway or after using cruise control. Transmission shifts from first to second gear and stays there until it's restarted. Requires turning off the car waiting a few seconds and restarting to reset the gears. Check engine light now starting to come on. Very dangerous when driving in heavy traffic or on the freeway. After researching this issue I cannot believe it simply hasn't been recalled. This is a very dangerous issue. . . I will not allow my wife to even drive the car unless I am with her. ----many forums are suggesting a valve body replacement. Appears to be a very common issue with these vehicle. Located a class action lawsuit that unfortunately was dismissed due to the complaint citing fraud. I don't believe mercedes sold these vehicles knowing the transmission was faulty. I would just expect them after receiving numerous complaints to offer their clients a repair option via recall. To date I am not aware of one. I have owned 4 mercedes in my lifetime, 38 years old and had a few minor issue here and there but never anything like this. Service has always been great but now that I am out of warranty I am left out in the cold. Not good for business in my opinion and very unsafe for anyone on the road while a mercedes owner is experiencing this issue.

30 Equipment problem of the 2008 Mercedes Benz S550

Failure Date: 08/10/2013

I was in unfamiliar area. Remote key would not operate. When using small key to enter vehicle car siren would not quit blaring and . New batteries did not help. Mercedes responder told me I had unoperative "dead" key. Car of course was unoperative. No way to move car from area. Could not secure car. I had rbm in atlanta on cell phone entire time. About hour later someone took me to my home for spare key. This worked. Key was as mercedes responder told me. . . . . . Dead. The mercedes keys are unsafe and undependable. Need to be recalled. Mercedes would not replace "dead" key per kyrus frames at rbm in atlanta. Because my car had 57000 miles on it and out of warranty. Key must be recalled due to safety concern there is no way to operate a "dead" key. Mercedes responder told me that he sees it all the time. What if??? I had been miles from home? unsafe area? compromising situation?this is unacceptable for $100,000 car. I could be dead. Just provide a workable key mercedes.
