Mercedes-Benz Reliability for the Year Ending June 30, 2018

General NotesHow do we select "competing car models"? Users of TrueDelta's car price comparison tool most often compare these cars to the Mercedes-Benz.

Models and statistics marked with an asterisk (*) have very low sample sizes. These results, visible only to logged-in members, provide only a rough estimate of car reliability.

Any result under 5 repair trips per 100 cars is likely a result of the small sample size, and should be expected to increase in future updates.

New models often start out with high repair rates, and then improve as the manufacturer identifies and addresses common problems. MethodologyOnly successfully completed repairs are currently included in the analysis. Routine maintenance, most wear items, recalls, and problems fixed with just a reflash or warning light reset are not included.

An asterisk (*) marks results based on small sample sizes.

Mercedes-Benz Reliability

You won't find Mercedes-Benz reliability information like this anywhere else. Actual repair frequencies, not just vague dots. So you can tell how much the Mercedes-Benz truly differs from competing car models in reliability.

These stats are promptly updated four times a year, to much more closely track Mercedes-Benz reliability as the cars age. Others tell you how reliable the Mercedes-Benz was a year ago, when the cars were a year younger and had 12,000 fewer miles on them. Only TrueDelta tells you how reliable the Mercedes-Benz has been recently.

What Our Members Are Saying about the Reliability and Durability of the Mercedes-Benz

Mercedes-Benz Reliability and Durability: Pros
YearBody/PowertrainComment
2010 4dr Sedan turbocharged 208hp 2.0L I4
9-speed shiftable automatic RWD		 Durability was second to none in the 70s and I am convinced that the new c class is a return to form. I followed the repair history of the 2008 and 2009 models and was pleased with both reliability and durability. see full Mercedes-Benz review
2010 4dr SUV turbocharged 255hp 3.0L V6 Diesel
9-speed shiftable automatic AWD		 As a Mercedes-Benz the overall quality has been above average in the longer term. see full Mercedes-Benz review
2010 4dr SUV Our previous vehicle was a 2005 Mercedes Benz C-240. From a reliability standpoint, the C-240 was flawless. I am hoping the GLK will be as good as the C-240 was. see full Mercedes-Benz review
2009 4dr Sedan 248-horsepower 3.5L V6
7-speed shiftable automatic AWD		 Owned for 7 months and have not yet had an issue with the vehicle. And still drives like the first day I got it, not had to have any car service for oil change or anything until 10k miles as per manufacturer guidelines see full Mercedes-Benz review
2009 4dr SUV 302-horsepower 3.5L V6
7-speed shiftable automatic AWD		 First crack out of the box with a 30K mile CPO: right pass door lock failed. Had to be replaced. Was under warranty. Would have cost $600. see full Mercedes-Benz review
2009 4dr Sedan 248-horsepower 3.5L V6
7-speed shiftable automatic AWD		 No issues with anything after a year, oil change every 10k miles, no wear and tear visible on interior seats or exterior. see full Mercedes-Benz review
2008 4dr Sedan turbocharged 208hp 2.0L I4
9-speed shiftable automatic RWD		 MB reliability and research of drive train is all in this C level car see full Mercedes-Benz review
2008 4dr Sedan AMG is a step above see full Mercedes-Benz review
2008 4dr Sedan turbocharged 255hp 2.0L I4
9-speed shiftable automatic RWD		 The 2008 E-Class is far more reliable than previous E-Class models, many of which are plagued by quirky electronic issues. No such issues with this model. Perhaps the most reliable model thus far. see full Mercedes-Benz review
2008 4dr SUV twincharged 362hp 3.0L I6 Hybrid
9-speed shiftable automatic AWD		 Very solid build quality. Feels just like all our other Mercedes we have owned in the past 30 years. see full Mercedes-Benz review
Mercedes-Benz Reliability and Durability: Cons
YearBody/PowertrainComment
2008 4dr Sedan turbocharged 255hp 2.0L I4
9-speed shiftable automatic AWD		 Driver side mirror cracked in the cold in the first 2 months. Piece of driver door trim came loose after a couple of months. see full Mercedes-Benz review
2008 4dr Sedan turbocharged 255hp 2.0L I4
9-speed shiftable automatic RWD		 Broken headrest. Auto wipers that work not that great, and no matter how much I changed or cleaned the wipers or the glass, it never works smoothly. Check engine light came on and had to replace a part. Water in one of the exterior mirrors. see full Mercedes-Benz review
2008 4dr Sedan turbocharged 255hp 2.0L I4
9-speed shiftable automatic AWD		 Poor reliability in the past 5-10 years see full Mercedes-Benz review
2007 4dr Sedan, ext. turbocharged 463hp 4.0L V8
9-speed shiftable automatic RWD		 My S550 had a transmission failure at about 45,000km. the torque converter casing had a flaw in it and it cracked. this stopped the car from being drivable. This should not really ahppen in a car costing in excess of $100,000 in my opinion. see full Mercedes-Benz review
2007 4dr Sedan It never works right. There is always some sort of other problem. Problem after problem after problem, it never ends. see full Mercedes-Benz review
2007 4dr SUV 302-horsepower 3.5L V6
7-speed shiftable automatic AWD		 No major things needed to be done yet. Just oil change and service B. It has 60k miles on it now. So far so good. see full Mercedes-Benz review
2007 4dr SUV twincharged 362hp 3.0L I6 Hybrid
9-speed shiftable automatic AWD		 Truck to some degree is overengineered. Review of history of supplier and manufactuing misses to include: missed welds (safety campaign) on the tow hitch, air compressor have premature failure due to "bad batch", fuel injector /cam position sensor , etc. see full Mercedes-Benz review
2006 4dr SUV 302-horsepower 3.5L V6
7-speed shiftable automatic AWD		 Transmission blew up at 30k. Covered under warranty, but bill was over 9k (reimbursed). Scary. Cup holder broke. Panoramic roof replaced twice. Front and rear windows replaced due to leaking. Out of warranty now and scared. see full Mercedes-Benz review
2006 4dr SUV 302-horsepower 5.0L V8
7-speed shiftable automatic AWD		 Very high maintenance poor reliability. see full Mercedes-Benz review
2005 4dr Sedan Materials look & feel great, and seem well put together, but durability is questionable. E.g., glovebox door soft close craps out, as do the tweeter "triangle" housings in the forward door corners). Airmatic suspension is known problem area. see full Mercedes-Benz review
