We almost got into crash the other day, our 8-year-old kid got our attention that rear seatbelt got very loose and did NOT retract back at all. he almost hit his head. when I asked him if it has been like this he said no, it was tight when I buckled it in. We tried several times to retract it manually with no luck. I checked online and I have seen people complaining about the same thing. we have been lucky we didn't hit the other car then my child will be seriously injured. This is a very serious safety requirement. I hope Mercedes Benz will take this very seriously as well, before others get hurt.

This past thursday evening (december 13, 2018) around 10:00 pm, I was driving (with my wife in the passenger seat) down a curvy stretch of road on sunset boulevard in beverly hills, when I suddenly heard a loud thumping sound and immediately felt violent vibrations through the steering wheel. since we were traveling at a relatively low speed of 30 mph, I was immediately able to re-gain the control of my vehicle and was able to pull over safely. once I got out of my vehicle, I immediately noticed that the front right wheel rim had completely broken into two halves. I was shocked and very surprised because nothing could have possibly explained why this wheel completely broke in the manner that it did. we were extremely fortunate that there were no other vehicles around us at the time the wheel broke, or that we were not on the highway traveling at much higher speeds, otherwise the results would have been fatal with even a possibility of significant injury or even loss of life. a complete report with pictures and cause of rapid fracture of the rim as a complaint was provided to mercedes dealership and corporate, they are refusing to admit to any material defect and liability.
According to the recall nhtsa campaign ID number: 16v899000 and the vehicle inspection report from the local mercedes dealership show as an identical issue. however, my vehicle IS not identified as apart of the recall. the recall states the issue IS due to the steering control unit not being soldered properly. difficult to think this falls under normal wear and tear. I will get the repair done begrudgingly, though it would be nice if mercedes would have stood behind its recall.
TL* the contact owns a 2014 mercedes-benz S550. While driving various speeds, the headlights failed to illuminate the roadway. The vehicle was taken to mercedes-benz of north palm beach (9275 fl a1aalt, north palm beach, fl 33403) where it was diagnosed that the headlight assembly and control module needed to be replaced. The vehicle was not repaired. The vehicle was previously repaired, but the failure recurred. The manufacturer was made aware of the failure and stated that the issue needed to be handled between the contact and the dealer. The failure mileage was approximately 18,497. The vin was not available.
TL* the contact owns a 2014 mercedes-benz S550. While driving 50 mph merging on the interstate, the sun roof shattered without warning. The vehicle was taken to the local dealer (mercedes-benz of mobile, 3060 dauphin st, mobile, al, 36606) where it was confirmed that the sun roof failed. Due to the failure, the vehicle also sustained body damage to the hood and trunk. The manufacturer was stated that they would give the contact a call back and send an investigator. The contact was referred to the dealer. The vehicle was not repaired. The contact also sustained a cut on the right side of the face due to the shattered glass.

TL* the contact owns a 2014 mercedes benz S550. While driving approximately 10 mph, the vehicle downshifted and suddenly there was a hard shift when the accelerator pedal was depressed or when stopped at a traffic light. The contact also noticed that there was a loud noise near the rear of the vehicle. The contact also noticed that the tilt function feature on the right passenger mirror failed. When functioning properly, the right passenger mirror tilted downward and to the right when the vehicle was placed in reverse; therefore, the driver could see all objects to the rear passenger side of the vehicle and in the vehicle's blind spot. The mirror failed to return to the driver's setting after shifting the vehicle into drive after being in reverse. The failure recurred multiple times. The dealer stated that the rear suspension system and the rear brakes needed to be replaced. The dealer also stated that they were unable to locate a failure with the mirror. The rear suspension system and the rear brakes were replaced; however, the failure with the mirror persisted. The manufacturer was notified of the failures. The approximate failure mileage was 2,000. The vin was unavailable.
This vehicle was purchased new in 2014. the vehicle has a reverse tilt function feature on the right passenger mirror. when functioning properly, the right passenger mirror tilts downward and to the right when the vehicle IS placed in reverse so that the driver can see all objects to the right rear of the vehicle (in the vehicle's blind spot). once the vehicle IS shifted into drive, the right mirror IS supposed to return to the driver's (memory) setting position for the mirror so that the driver IS able to see out of the right mirror when driving on the highway. the mirror on this vehicle fails to return to the driver's (memory) setting after shifting the vehicle into drive after being in reverse. the mirror remains in the downward and to the right position thus leaving the driver completely unable to see out of the mirror when driving on the highway. the driver IS forced to take his/her eyes off of the road, and the surrounding vehicles, to manually adjust the mirror thus placing the driver and all passengers at a significant risk of injury. while it IS unconfirmed, this vehicle was involved in a side-swipe type motor vehicle accident, and it IS suspected that this mirror defect was a contributing cause to the accident. mercedes-benz USA IS aware of this defect and IS aware that at least two cases have been reported in the united states in the 2014 S550 model. Mercedes-benz USA IS also aware that this defect exists in the 2015 S550 model. mercedes-benz USA has been given numerous opportunities to cure this defect and it has failed/refused to make the repair, thus exposing all 2014 and 2015 S550 drivers, and their passengers, to a significant risk of injury.
Aggravating noise associated with high pressure fuel pumps, tick, tick, ticking noise at any speed. Complained to dealer, but despite exchanging pumps, noise persists. Complained to mbusa, was told this was a 'normal noise'. Sounds like an oxymoron to me. Very disappointed with car noise and response to my plea for help. *tr
I was on a test drive. cruise control was on. speed was 55mph. van pulled in front of me and decelerated. mercedes maintained speed and was closing rapidly. applied brakes hard to avoid rear ending van. *tr
I purchased a new 2014 mercedes S550 and the day after purchase, the airbag malfunction light came on. I set up an appointment to have this corrected, and was told it was fixed. a couple of weeks later, I was traveling at approximately 20mph, approaching an intersection where I did not have a stop sign. I noticed a large SUV traveling east bound at excessive speeds (guessing 35-40), which did not appear to be stopping, but could not stop in time to avoid the collision. the SUV impacted the driver's side of my vehicle at full speed. my vehicle spun and was hit again at the side and rear driver's side. I was pushed over the curb and into a snow bank where I eventually stopped after hitting the yield sign. I was trapped in my vehicle as I had carved thru the snow and all doors were blocked. the damage to the vehicle was on the driver's side front, side and back. the hit was hard enough to cause frame damage to the vehicle, needing frame repair. there were no airbags deployed during the crash and given the previous malfunction with the airbag system, this was a major concern for me. I notified mercedes benz of the issue, and it wasn't until several requests that they responded. they sent someone to the body shop to look at the car and confirmed there IS frame damage; however, stated it was not hard enough of a hit to trigger airbag deployment. I have a hard time understanding how it can be hard enough to cause frame damage yet not trigger airbag deployment? this IS a completely redesigned vehicle and mine was one of the first on the road. I am fearful that this IS a larger issue that IS not being addressed, or uncovered, since this IS a recently released model. as a result of the impact, I sustained injuries to my neck, back and left elbow. I am hoping this could get address to avoid future injuries, or death, to other drivers and passengers. thank you. *tr
NHTSA’s Office of Defects Investigation opened these reviews into vehicles including this one.
On January 8, 2021, after ongoing review with Mercedes Benz, the National Highway Traffic Safety Administration (NHTSA) Office of Defects Investigation (ODI) opened PE21-001 to assess allegations of front roof panel detachments while driving at highway speeds in certain 2015 Mercedes-Benz (Mercedes) C-Class vehicles.The subject front roof panel is a stationary panel composed of polycarbonate and is attached to the vehicle via adhesive at the time of manufacture. The panel is found on subject vehicles equipped with panoramic sunroofs. Over time, the subject panels may exhibit cosmetic degradation leading to replacement of the panel, a procedure which entails: removal of the old panel and adhesive, site preparation, and installation of a replacement panel with new adhesive.The consumer complaints that prompted the opening of PE21-001 all described detachments of front roof panels that had been replaced after the vehicle was put into service.Mercedes' internal investigation identified a broader scope of affected vehicles (2014-2020 CLA, GLA, C, S, GLC, and GLE class) and found the following potential service procedure- related causes of front roof panel detachments:- Improper surface pretreatments such as the use of the wrong primer or cleaner or scoring of the surface; or - Use of the incorrect adhesive.These conditions lead to a front roof panel bond that, even if sound at the time of repair, cannot maintain its strength over time and environmental exposure.Mercedes updated its service and parts ordering systems to reinforce the proper use of specified kits and procedures via webinars, shop foreman meetings, and explicit reference to the risks incurred by diverging from the repair procedures. Mercedes is also furnishing parts ordering assistance, and will hold dealerships accountable for improper repairs.ODI's analysis of the ten complaints it has received from the public (VOQ's) and MBUSA's complaint data submitted in response to the information request letter for PE21-001 identified a total of 57 non-duplicative reports alleging incidents in which the front roof panel detached from the vehicle while in motion. Included within the 57 reports are incidents where consumers state the panel detached ...and flew off into traffic.On March 19, 2021, Mercedes notified NHTSA that it would recall subject vehicles with front roof panels known to have been replaced after the original sale of the vehicle. In total, the recall (designated as Recall 21V197) covers 15,099 vehicles that were ever registered in the United States. Based on Recall 21V197 and the remedy implemented by Mercedes, further investigation does not appear to be warranted at this time.Accordingly, this investigation is closed.The ODI complaints cited above can be viewed at www.nhtsa.gov under the following ODI identification numbers: 11376425, 11352686, 11351629, 11349158, 11341541, 11337594, 11324100, 11311591, 11222127, 11404183
