C Class not the worst in consumer reports reliability




"Only" 82% below the average!
Really not a surprise for most of us that bought the first production.
Not surprisingly the most common defects reported were all the ones I suffered. Suspension, Infotainment, Electronic controls (Door sensors). They also mentioned the 4matic which has not been a problem for me. Lets hope that these are only first year "teething" issues.
At least it did better than the ATS and the Acura TLX. The TLX was surprisingly bad primarily because of a bum 9 speed transmission.
For non USA residents, the TLX is a North American "luxury" version of the Honda Accord, usually very reliable.
Unfortunately the 2015 C300 I have is the worst car I've ever had. Having MB buy my lease out early based on they've had it more than I have. Terrible build quality IMO. Aside from nice interior appointments and nice handling, nothing luxury about it. It seems beyond teething problems of how adamantly MB is at calling defects normal.
Going to probably buy a Lexus. Not as engaging to drive, but blows MB away in any other luxury metric IMO. Will see what kinks the Germans can work out on next generation or so. If they could only get their QA together, they really would have something.
I'll tell you though, I'll be looking real hard at the 2017 BMW 328i xDrive with the new 4 cylinder engine, and a 2017 Lexus IS350 AWD if it comes with that new 8 sp transmission.

Mine hasn't left me at the side of the road, but has had many visits to the dealer for annoyances, firmware, steering, noise, gas door, touch pad, brake adjustment, the list goes on.
Outstanding designs, poorly executed. I don't think Mercedes will take that as their marketing slogan, but it wound unfortunately fit. Frustrating. I'd sell, but check the postings, these cars are being sold a dime a dozen used. Found one near me, C400 with 8200 miles, pretty loaded, $31k asking.

As to going the Lexus path, I test drove an AWD GS back to back with the C Class, a totally disappointing experience. The "luxury" was subpar, the engine was basically "adequate", the handling was poor and the electronic interface was just as bad or worse than MB. In fact it was worse than a C300 in basically every respect. It felt no better than a glorified Toyota with better leather. I guess if you never go faster than the speed limit and feel over the hill an LS might be a good option, otherwise, I would avoid Lexus entirely. I'll take some little frustrations over being bored to death all the time.

I have no idea why there is such a huge contrast between that early car's horrible build quality and the virtually trouble free experience I am having with my current C300. The VIN jumped from the 27xx range into the 61xxx range, but that alone doesn't explain the differences since the components are essentially the same. At best, perhaps, it means that someone may be finally getting a handle on the Alabama assembly process and the previous lack of any apparent QC. At worst, it may be nothing but luck in randomly getting a well built car. In any case, it seems to be a learning process that the consumer should never have been exposed to. For everyone's sake, I can only hope that the 2016 production run has finally progressed beyond the beta testing stage.

I bring this up as they're on the polar opposite of MB on reliability. I didn't think the MB would be completely ironed out, or even to Hyundai level, but didn't think it would be this bad.
While my C is a wonderful design and engaging car to drive when it works if you can ignore the bugs, replace run flats, windows, etc.... NOTHING is more boring and aggravating at the same time than the MB ownership experience where defects are all either normal, or part of the design according to their manufacturer.
Still waiting to hear that they'll take it back on lease and sell it to some other sucker.

The steering has a bug in it that they can't find, it gives the warning, will reset if left alone for 15-20 minutes, and yet to be fixed by firmware. Fuel door was ok new, but after closing door after fill up, it's crooked. I'm not that strong. I just pushed in about half an inch. Required rework, and they said I had damaged it...wasn't covered. They contacted MBUSA who said "No fuel doors on a 2015 c class have had any alighment issues to date'. My command volumes are erratic, and they changed the unit, and tried several firmwares, no luck. They say it's hopefully going to be addressed in a future patch. There's a buzzing sound, from the drive line or rear end differential when vehicle isn't accelerating that is new, they say it's normal. That's all I can think of now.
Great group of folks here! i just feel badly they didn't get the kinks worked out. Cool looking and driving car, when it works.
My issues were more with once hitting an issue, MBUSA acting like I'm the first one to express the concern.
I understand refresh year cars have bugs. They just don't get fixed or keep customers with the MBUSA mentality. I don't mean to be negative either. I had high hopes, and relatively low expectations for this car. I went through 2 of them.
Hopefully my C will be gone soon enough. Great handling concept car. A finished refined product, even if boring to drive, sounds most luxurious and appealing to me about now

With 4 kids, the c was a bit of a down stretch but I would have done it. Getting a GS Fsport. Handling beat the A6, E 400 (it's size equivalent) IMHO when I drove them and turns out many road test articles agree. Not near the straight line punch, but more than I will get to use often. I had the same "it's a fancy Toyota appliance" mentality and only drove it to kill 2 hours in between other appointments. Put it in Sport + and left it there. I was shocked that I enjoyed it.

The older brand snobs, or many on this board likely to scoff at Lexus as it's a newer brand, or think less of Toyota making it, but anyone in the know realizes Toyota's build process puts MB to shame on every model, every year, every car. Not luck of the draw like with this car. I'll say it shouldn't be that way, but it is. MB has gizmos and driving engagement, but that's where it stops. They kinda returned to the early 2000s. Poor builds, and MB, especially MBUSA not standing behind the products. I'm disheartened. The reliability numbers don't lie. And I think they're actually being kind to the German auto makers.
All that said, I realize we're on an MB forum, and many will disagree with me. CR, JD Power, and owners of the cars won't though.
