Airbag Problems: Tackling Safety Concerns

The most frequently reported issue affecting the ML350 pertains to airbag problems. Specifically, numerous complaints are linked to the notorious Takata airbag recalls, affecting models predominantly in the 2010 and 2011 lineup.

These recalls encompassed millions of vehicles, not limited to the ML series, where the Japanese-made airbags exhibited catastrophic failures upon deployment, leading to severe injuries and fatalities in certain cases.

Addressing this critical safety concern requires vigilance. Considering purchasing a used ML, running the vehicle identification number (VIN) through Mercedes or NHTSA’s website is imperative to ascertain if your vehicle falls under a recall.

Due to the severity of this issue, seeking resolution through authorized dealerships is crucial.

Faulty Camshaft Adjuster Solenoid: Engine Performance Woes

A prevalent problem reported across various model years, including 2006, 2007, 2008, and 2012, is the malfunction of the camshaft adjuster solenoid.

Responsible for regulating the variable valve timing (VVT) system, a failing solenoid triggers multiple symptoms, including reduced fuel efficiency, contaminated engine oil, rough idling, and compromised engine power.

Unresolved issues could lead to more substantial engine problems, as reported by dissatisfied ML owners facing significant repair costs.

Addressing this issue necessitates prompt replacement of the faulty camshaft adjuster solenoid.

While the presence of a recall remains uncertain, consulting with dealerships or utilizing independent repair shops for cost-effective solutions is recommended.

Rough Shifting: Transmission Challenges

ML350s equipped with automatic transmissions frequently exhibit rough shifting, spanning model years from 2003 to 2015.

Owners have reported noticeable transmission issues during gear transitions, especially in colder conditions, accompanied by clunking and grinding noises.

Identifying this problem during a test drive of a used ML350 becomes crucial for prospective buyers.

Resolving rough shifting concerns might involve a mere transmission software update in some cases.

However, in more severe instances necessitating internal component replacements, Mercedes has released updated parts. Addressing these issues might require transmission disassembly for effective repairs.

Engine Stalling: Uncommon Yet Troublesome

While not as widespread, engine stalling has been reported among ML350 models from 2006 to 2012. Stalling, indicative of engine shutdown, has led to complaints related to the failure of engine control module pins.

Resolving this issue might involve simpler remedies or, in extreme cases, demand costly engine replacements, making it a potentially significant financial burden for owners.

According to Repair Pal, the primary causes of engine stalling relate to the fuel system, air intake system, and ignition system, emphasizing the necessity of thorough diagnostics and expert interventions.

Addressing this issue typically involves replacing the lamp housing, incurring costs upward of $250 for repairs.

Power Steering Problems: Steering Safety Hazards

Numerous complaints revolve around power steering problems in the ML350, spanning model years predominantly from 2006 to 2008, though affecting earlier and later models as well.

Owners have reported uncontrollable steering and power steering loss, often accompanied by fluid leakage, posing significant safety risks.

Identifying early signs of steering rack leakage is crucial to prevent potentially catastrophic failures while driving.

Remedying this issue might demand steering rack replacements, costing upwards of $2000. However, recall campaigns for steering problems might offer resolutions through authorized dealerships at no cost.
