Mercedes ML350 Problems

The Mercedes ML350, a blend of luxury and performance, has earned its place among SUV enthusiasts. However, beneath its sleek exterior and opulent features, some common issues have come to light.

We delve into the most frequently reported Mercedes ML350 problems, provide insights into their causes, and offer solutions to navigate these challenges.

Mercedes ML350 Problems

1. Airbag Problems: The Unsettling Takata Recall

One of the most concerning issues affecting the ML350 is related to its airbags, particularly in the 2010 and 2011 model years. The infamous Takata airbag recalls, which impacted numerous vehicles beyond the ML350, raised significant safety concerns.

These Japanese-made airbags were found to be prone to explosion when deployed in high heat and humidity, leading to severe injuries and, in some tragic cases, fatalities.

Furthermore, delays in parts availability exacerbated the problem, leaving many owners frustrated and exposed to risk.

## Solution: To ensure your vehicle’s safety, always check if your ML350 has been subject to a recall. Running the VIN on the Mercedes or NHTSA website can provide crucial information.

Given the gravity of this issue, it’s essential to rely on dealership expertise for resolution.

2. Faulty Camshaft Adjuster Solenoid: Engine Performance Woes

One of the most commonly reported issues affecting the ML350 is the failure of the camshaft adjuster solenoid. Model years worst affected include 2006, 2007, 2008, and 2012. The ML350 employs a variable valve timing (VVT) system that regulates intake and exhaust valve timing.

The camshaft adjuster solenoid controls oil flow within the VVT system.

Signs of failure include check engine light illumination, reduced fuel efficiency, contaminated engine oil, rough idling, rough acceleration, and diminished engine power.

## Solution: Addressing a failed camshaft adjuster solenoid requires replacement. While recalls aren’t entirely clear for this issue, consulting the dealership or running the VIN can provide clarity.

If out-of-pocket expenses arise, utilizing independent repair shops might offer cost savings compared to dealership repairs.

3. Rough Shifting: Transmission Troubles

Rough shifting, often accompanied by clunking and grinding noises, is a commonly reported complaint among ML350s with automatic transmissions.

This issue spans model years from 2003 to 2015, primarily noticeable during gear shifts when the vehicle is cold or transitioning between specific gears.

Solving rough shifting problems may involve transmission software updates or replacing internal components.

## Solution: If you encounter rough shifting, it’s wise to consult professionals. While software updates might alleviate the issue, updated parts from Mercedes could be necessary if internal components are at fault.

4. Engine Stalling: A Disconcerting Occurrence

Though not widespread, engine stalling has affected some ML350s, predominantly within model years 2006 to 2012. Stalling occurs when the engine abruptly cuts out, leading to potentially hazardous situations.

While some instances stem from engine control module pins, others have required expensive engine replacements.

## Solution: Addressing engine stalling depends on the underlying cause. Remedying issues related to the fuel system, air intake system, or ignition system may resolve stalling. Consultation with professionals is essential to determine the best course of action.

5. Brake Light Warning Message: Electrical Concerns

The brake light warning message, often indicating a burnt-out bulb, has been repeatedly reported across various model years, from 2003 to 2015. This issue is linked to tail lamp housing melting, resulting in poor electrical connections or bulb failures.

## Solution: Rectifying the brake light warning message involves replacing the affected lamp housing. This repair can prove costly, typically exceeding $250.

6. Power Steering Problems: Loss of Control

Owners have voiced concerns about power steering issues, including loss of control and fluid leakage. This issue has been reported in model years from 2003 to 2013, with higher frequency from 2006 to 2008.

Power steering rack leaks have caused fluid puddles and, in extreme cases, complete steering failure.

## Solution: Depending on the extent of the problem, a power steering rack replacement might be necessary, costing around $2000. Some instances have been addressed through recalls, with dealerships offering free fixes.
