I procured the vehicles 32,000 miles as a cpo. It had new brake rotors on it. Over the next 75,000 miles the brake rotors had to be replaced 7 times for warping and dangerously increasing stopping distances. This apparently not unusual for this vehicle.

Each bar shows the share of total complaints filed at that mileage range. Peak failure window highlighted. Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits and driving conditions shift the curve as much as mileage alone.
What stands out
No new NHTSA brakes complaint has been filed on this vehicle in over 7 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: The 2010 E-Class has a documented pattern of brake hardline corrosion that can cause complete brake failure, requiring expensive subframe-dropping repair; additionally, rotors warp and wear rapidly and repeatedly, sometimes needing replacement multiple times across normal ownership.
Brake hardline corrosion ranks as the most serious complaint. Multiple owners describe finding the rear brake lines heavily corroded and leaking, with visible damage to hardlines and heat shields. Brake fluid drains out—one owner found the reservoir completely empty after only a warning light appeared. The failure pattern hits across the mileage spectrum: one garaged vehicle with just 43,000 miles developed leaking brake lines; others failed in the 85,000–125,000 range. The real kicker is that complete brake failure has occurred while owners were actively driving—one lost brakes entirely at 25 mph in traffic, another experienced full pedal collapse approaching an intersection. Repair cost runs $2,500–$3,500 and requires dropping the rear subframe, a major undertaking. Mercedes issued a recall for subframe rust but has not included the brake lines despite owners noting the corrosion issues appear linked. Beyond hardline failures, owners report brake rotors warping and wearing out repeatedly—one owner replaced rotors seven times over 75,000 miles after buying the car CPO with new rotors already fitted. A separate complaint mentions persistent brake noise and poor pedal response requiring early braking; the issue recurred after two service visits in one year.

Failure modes owners describe
Rear brake line corrosion and leakage
Brake hardlines, particularly the rear brake line near the gas tank, corrode and develop leaks causing brake fluid loss. Owners report corrosion visible on brake lines and heat shields, fluid dripping beneath the vehicle.
When: 32,000 to 125,000 miles; one owner with only 43,000 miles in a garaged vehicle
Symptoms owners cite: Brake fluid warning light illuminates; Brake fluid reservoir empty or low; Visible corrosion on brake hardlines; Brake fluid leaking under vehicle; Brake pedal sinks to floorboard; Complete brake failure while driving
Repairs/costs cited: Repair requires dropping rear subframe; estimated cost $2,500–$3,500 per Mercedes dealer quote. Some owners report the extended warranty does not cover brake line corrosion.
Recalls/TSBs owners mention: Mercedes issued a recall for rusty subframe on this model; brake line corrosion not included in that recall despite owners noting the two issues appear related.
Brake rotor warping and rapid wear
Brake rotors warp repeatedly and wear prematurely, causing extended stopping distances and requiring multiple replacements within short intervals.
When: Across 75,000 miles of ownership following initial CPO purchase with new rotors
Symptoms owners cite: Increased stopping distance (dangerously lengthened braking); Rotor warping; Rapid rotor wear requiring frequent replacement
Repairs/costs cited: One owner replaced brake rotors 7 times over 75,000 miles after purchasing the vehicle as CPO with new rotors already installed. Owner notes this pattern appears common for the model.
Brake noise and pedal responsiveness issues
Squealing or squeaking noise from the brake system; brake pedal requires early and extended pressure to achieve adequate stopping power.
When: Not specified; one owner required brake service twice in same year
Symptoms owners cite: Squealing or squeaking from brakes; Brake pedal requires unusually early application; Reduced responsiveness requiring extended stopping distance; Persistent problem after multiple brake replacements
Repairs/costs cited: Brake service performed twice within one year; issue recurred after both services.

At what mileage does the brakes typically fail?
Based on the 11 complaints filed, brakes issues most often appear around 72,958 miles. Some report problems earlier; some make it well past 150,000 with no symptoms. Maintenance habits matter — vehicles that received timely fluid services and were not regularly overworked tend to last longer.
What does it cost to fix?
Independent shops typically charge around $450 for brakes repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to brakes?
No active recalls currently cover brakes issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
