Not crash-tested

New Car Assessment Program

The 2017MERCEDES-BENZS550 carries 20 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 0 crashes, 0 fires, 0 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.

Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2017 S550 is steering with 3 filings, followed by unknown or other (3) and visibility/wiper (2). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 10 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.

NHTSA currently has 15 investigation files overlapping the 2017 S550. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration. Use the related-complaint feed below to read raw owner narratives before deciding whether any pattern here affects your specific use case.

20240627EXTERIOR LIGHTING:HEADLIGHTS

This car since new has had moisture in the headlight from rain or washing. MB has installed moisture packets in the headlights that they said would fix the problem. It never did. I called the dealership and complained, they said sorry but that was their fix (MB TSB LI82.10-P-062051). Now the lights have failed, and they want me to spend $10K to replace the headlights and continue with the same issue. The problem still exists with the new headlights. This is not only a poor way to fix an ongoing problem (Moisture packets) for something that is severely related to safety on the highways in America. I believe you will agree. Please respond? Thank you

20240405FUEL/PROPULSION SYSTEM

I was sold a vehicle by a dealership with a busted gas tank. It appears to have been an attempt to repair it with patching material. I am unsure if the defect was a result of manufacturing versus acquired damage. My safety is at risk because of leaking gas that could potentially ignite and inhaling strong gas fumes that could impact my lungs and health. The fuel tank damage has been confirmed by a mechanic and documented. It has not been inspected by any other entity while in my possession other than reported inspection by the dealership. I secured the vehicle on [XXX] from the dealership with these safety concerns. A mechanic stated the damage could have resulted either with the dealership or during on and off the trailer during transport of the vehicle from Florida to Indiana.

20230414STEERING

Had my S550 into this dealership two (2) consecutive years for a power steering rack issue that ended up being related to rodent damage. The first time it happened the dealership replaced the wiring free of charge after discovering it, after initially telling me that the rack itself would have to be replaced. This year both the wiring and the rack itself needed to be replaced, and I was made to go through my auto insurance to have it fixed. My sons Cadillac, and my girlfriends Range Rover Sport share the same driveways with me, and have had no rodent damage. I did a bit of research and found that Mercedes now designs their cables with soy based materials, which attract rats, so the fact that my car has been eaten twice is more or less by MB design, as they apparently care more about the environment than they do about my ability to steer my car continuously for 1 year straight. My service Manager and his Manager acknowledged that they see this a lot, and were laughing when I asked

The vehicle panoramic sunroof came across a discrepancy that can damage the owner and other innocent vehicles on the road. Since it has been stuck on one side it can possibly break and fly off. The vehicle has been recalled, unfortunately my vehicles vin number was not chosen although it has the similar problems that the recall vehicles had. The front roof panel located between the windshield and the panoramic sunroof may not have been bonded correctly to the vehicle during a prior repair.The adhesive bonding of the front panel might deteriorate, possibly causing the front panel to detach from the vehicle and become a road hazard, increasing the risk of a crash.
