On two occasions I had loss of tire pressure on front wheels. Examination showed the alloy wheels to be cracked. This has happened two times in approximately 90 days. I have not hit any pot holes. Some typical road bumps maybe but no deep holes. I've had many vehicles since 1958 but never had wheels cracking. Research has shown quite a bit of people with the same low profile tires used on…

When does it fail?
Of the 11 wheels complaints filed for the 2008 Mercedes-Benz E-Class, here's the actual mileage breakdown — failures cluster heaviest at 25,000-50,000 mi.
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.
Of the 9 model years of Mercedes-Benz E-Class we track for wheels problems, this one carries the most owner complaints on file — 11.
No new NHTSA wheels complaint has been filed on this vehicle in over 13 years — the issue may be aging out of the active population.
The failure pattern owners describe
Owners of 2008 Mercedes E-Class sedans report consistent cracking and bending of the 18-inch alloy wheels from ordinary road encounters—potholes, bumps, and minor irregularities. The problem stems from the pairing of larger-diameter wheels with low-profile tires: the tire sidewall measures only 2–3 inches, down from 3–4 inches on earlier models with 16–17 inch wheels. That thinner sidewall offers less cushion between rim and pavement, making wheels brittle under impact.
Failures occur early and repeat. Owners report bent or cracked wheels as early as 5,000 miles; one owner replaced three rims in 2.5 years despite no curb strikes or rough driving. When wheels bend, tires develop bubbles or blowouts, and bent wheels can damage axle components. Symptoms include thumping noises, rapid air loss, tire blisters, and complete blowouts.
Dealers perform wheel and tire replacements inconsistently under warranty. Many owners absorb the full cost. Mercedes attributes the problem to road conditions and declines to acknowledge a design flaw. No recall or technical service bulletin addresses the issue. A tire professional with 15+ years' experience states the 18-inch wheel choice deliberately prioritizes appearance and handling over durability, knowingly trading robust sidewall protection for thinner rubber.
Failure modes owners describe
Cracked or bent 18-inch alloy wheels
18-inch diameter alloy rims develop cracks or bends from relatively minor road impacts (potholes, bumps). The low-profile tire design paired with larger wheel diameter reduces sidewall height (2–3 inches versus 3–4 inches on older 16–17 inch wheels), leaving less cushion between wheel and road. Owners report repeated failures; some replace three wheels within 2.5 years despite careful driving.
When: From 5 miles to 33,000 miles; reported across multiple vehicles within first 2–8 months of ownership
Symptoms owners cite: Visible cracks in alloy wheel; Wheel bent or out of round; Rapid tire pressure loss; Thumping noise while driving; Tire blisters or slow leaks; Complete tire blowouts
Repairs/costs cited: Owners report replacing wheels and tires at their own cost; some have replaced two front rims, one rear rim, or multiple wheels over vehicle ownership. One owner replaced 12 tires and 3 rims in two years. Dealers have performed wheel replacement and alignment under warranty in some cases; warranty coverage inconsistent.
Recalls/TSBs owners mention: Mercedes acknowledges only that the vehicle can be equipped with low-profile rims and attributes failures to road conditions (potholes). Warranty does not cover tire and wheel replacement in most cases. Mercedes has not issued a recall or TSB addressing the design flaw.
Wheel/tire failure causing secondary damage to axle and suspension
Bent or cracked wheels cause downstream damage to axle components and tires. One owner reports three of four wheels were bent and cracked, and the bent wheels caused problems on the axle that were not covered under warranty.
When: 33,000 miles
Symptoms owners cite: Thumping noise from wheels; Three of four wheels bent and cracked; Axle damage following wheel failure
Repairs/costs cited: Dealer repaired wheels under warranty but did not cover axle repair or tire replacement, arguing those failures resulted from the wheel damage rather than manufacturing defect.

Common questions
How serious is the wheels problem on the 2008 Mercedes-Benz E-Class?
It's a documented issue but not catastrophic. 11 complaints have been filed. Repairs average $400 and most owners catch it before it causes a breakdown.
At what mileage does the wheels typically fail?
Across the 9 complaints that reported odometer mileage, most wheels failures cluster between 15,000 and 33,000 miles, with the median around 25,000. A quarter of owners report trouble before 15,000; a quarter make it past 33,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $400 for wheels 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 wheels?
No active recalls currently cover wheels 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.
