The 2011 Mercedes ML350, while a luxury SUV, has been reported to have several problems. This article details one owner’s frustrating experience with various issues in their ML350, ranging from persistent headlight malfunctions to recurring noises from the cargo area and dashboard.
Common 2011 ML350 Problems: One Owner’s Story
Within a day of purchasing a new 2011 ML350, the owner encountered a recurring issue with the headlights and taillights failing to turn off, even in broad daylight. Despite demonstrating the problem to the dealership, the issue remained unresolved. The dealer simply disabled the daytime running lights (DRLs) and dismissed the concern.
Recurring Noise Issues Plague the ML350
Beyond the headlight malfunction, a series of noises plagued the vehicle. A clunking noise from the rear cargo area was eventually traced to improperly insulated seat belt anchors. However, a persistent cracking noise from the dashboard and windshield area continued despite multiple attempts by the dealership to fix it. The technician’s attempts to remedy the issue, including rearranging the media cable in the glove box, proved ineffective.
Further noise issues arose from the cargo area, including rattling sounds resembling a loose tool in a bucket. After nine days at the dealership, the problem was attributed to a misaligned tailgate. Yet, the windshield noise persisted, returning just two days later.
HVAC and More Noise Problems
The problems continued with a chattering noise emanating from the HVAC fan control, necessitating another service visit. The blower motor was replaced, and parts of the dashboard and A-pillar were insulated. However, the recurring headlight issue remained unresolved.
Subsequently, three new noises emerged from the cargo area: a clunking over bumps, a metallic clanging, and a creaking sound. Despite the owner’s thorough checks, no loose items were found that could explain these sounds.
Dealing with Mercedes-Benz USA and the Dealership
The owner contacted Mercedes-Benz USA (MBUSA) for assistance, but found their case worker unhelpful and condescending. The dealership’s service manager and general manager offered a two-payment waiver for the downtime, but the owner requested four.
Conclusion: A Disappointing Luxury SUV Experience
Compared to previous SUV ownership experiences with other brands, the owner found the 2011 ML350 to be significantly more problematic and less reliable. The numerous issues, coupled with the frustrating interactions with the dealership and MBUSA, resulted in a disappointing ownership experience. This account highlights potential problems prospective buyers should be aware of when considering a 2011 Mercedes ML350.
