A Buyer’s Guide to the 2012 Mercedes Benz S350 BlueTec

The 2012 Mercedes Benz S350 BlueTec brings diesel to the S-Class line in an extravagant way. With exceptional luxury, comfort and performance, you’ll have to schedule a test drive just to experience it for yourself. Once you do, you might be hard pressed to walk away to any other clean diesel option available.

Key Features

In addition to host of standard features available on this model, some of the more notable ones include Attention Assist which keeps an eye on the driver’s alertness, Torque Vectoring Brake, which adjusts the braking on the rear wheels when cornering, and the 600-watt surround sound Harman/Kardon stereo system with 14 speakers. There are also numerous Assistance Systems features available for add-on as well.

Changes for 2012

2012 is the first year for the 2012 Mercedes Benz S350 BlueTec, which introduces a diesel V6 engine that delivers 240 horsepower and 455 lb-ft of torque for a powerful punch throughout the driving experience.

What We Like

There’s no denying that the 2012 Mercedes Benz S350 BlueTec offers a level of prestige for any driver, but the rich interior and nimble performance make this car a dream to drive as well. The 4MATIC all-wheel drive also improves the acceleration and fuel economy at a better price than some of the other S-Class offerings for a complete luxury experience.

What Concerns Us

Given all the benefits of the 2012 Mercedes Benz S350 BlueTec, there is a bit to be desired with the braking, which requires 181 feet to reach full stop from 70 mph. The steering is also a bit lax, as it feels as if direction changes are a bit sluggish due to understeering. You’ll likely want to avoid the all-season tires as well, as they don’t add much to the already lacking grip.

Available Models

In the S350 BlueTec you will find:

  • 3.0-Liter Diesel V6
  • Horsepower: 240 @ 3,600 rpm
  • Torque: 455 @ 1,600-2,400 rpm
  • City/Highway Fuel Economy: 21/31 mpg

Major Recalls

There have been no major recalls issued for this vehicle.

Common Issues

There are only two complaints that have been made about the 2012 Mercedes Benz S350 BlueTec. The first complaint was made at around 50,000 miles; at which point the charge air hose going into the throttle actuator had to be replaced due to being torn. The second complaint involved the radiator grill breaking when an owner closed the hood on the vehicle.

Chevrolet Impala V6-3.6L - Pre-purchase Car Inspection - Lansdale, Pennsylvania
Shawn was prompt, professional, and delivered the promised service as expected. This was a used vehicle pre-purchase inspection. Shawn also had to drive to multiple locations to perform the inspection, as the address listed that I provided him with was not accurate, but he still made it to the correct location within his time window and completed the inspection.
Toyota Sequoia - Pre-purchase Car Inspection - Akron, Pennsylvania
Shawn was very prompt in communicating with me and was good at helping me decide whether to purchase a used car. He help me avoid a car with a repaired rusted frame that could be a danger to my family's safety since we were planning on using the car to tow a travel trailer!

Acura RDX - Pre-purchase Car Inspection - South Hackensack, New Jersey
Luis did a thorough pre-purchase inspection for me, and found several major issues that made me pass on buying the car. Had I purchased the car, I almost certainly would have ended up paying thousands in repairs down the road. Thanks Luis!

He did a pre-purchase inspection for me. He was knowledgeable and fast, and knew what he was looking for. I really appreciate all the pictures and documentation he took of the state of the car before purchase. He noted potential issues with the car that I wouldn't have been able to notice. Would recommend.

I trust Robert. He gave me a list and we will take care of it the week of June 29. I will know then that my vehicle is ready for the winter and is safe to drive. I look forward to getting things ready for another winter of careful driving.
