2015 Mercedes C-Class owners reporting bleeding seats [UPDATE]

UPDATE: Daimler AG became aware that, in a small number of individual cases, it is possible for temporary spots and/or shiny patches to form on the man-made leather surfaces of the 2015 C-Class in sub-freezing temperatures. No accidents or injuries have been reported, and we have no reason to believe that there are any hazards to customers. Replacement parts are expected to start shipping to dealers by next week. Owners of the 2015 Mercedes-Benz C-Class are learning the hard way that you don't necessarily want to buy a new vehicle in its first model year. Besides reports of poorly fitting taillights and faulty infotainment touchpads, a number of reports are popping up on the forums of MBWorld.org claiming that the compact luxury sedan's seats are, for lack of a better term, bleeding. Owners of US-built, 2015 C-Classes fitted with MB Tex vinyl interiors are reporting a white, oily, shiny residue discoloring their seats that shows up, often after cold cars are quickly heated. It's important to note that this residue is not necessarily staining the seats permanently – warm, soapy water is often all that's needed to restore the original finish. In other cases, the residue disappears of its own accord, only to reappear in an entirely different pattern. That doesn't make things any more acceptable to owners, many of whom have reached out to Mercedes with complaints. It's not clear how many vehicles are affected, but there are a sizable number of forum threads on the issue on MBWorld alone, and the problem is prevalent enough that Mercedes has issued a technical service bulletin to its dealers. According to the forum postings, the TSB instructs service technicians to replace the headrest and seat cover (except for the front, passenger-side seat bottom because of "factory calibration issues") in affected customer vehicles. New C-Class models in dealer inventories, meanwhile, are to get the soapy water treatment if they're showing signs of the residue. Neither one of those moves seems to represent a long-term fix, though. Black MB Tex seats – both the standard and sport variety – seem to be particularly susceptible to the residue, although we stumbled across at least one image of what looks like Silk Beige MB Tex with speckles of residue.

VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of testing by governments, outside safety agencies and automakers to approve the chemical for use in cars. It passed the protocols necessary for the European Union to declare that new and significantly revised cars from 2013 onward needed to use R-1234yf, and mandated that every car as of 2017 must use it.
Enter Daimler AG. The automaker created a head-on collision test with a B-Class at their Sindelfingen test track that would lead to the pressurized refrigerant being sprayed on the engine. The result in 20 out of 20 test was that the refrigerant burst into flames as soon as it hit the hot engine, while Daimler says that R-134a does not catch fire in the same test. Another unexpected result of the R-1234yf test was the release of hydrogen flouride, a chemical far more deadly to humans than hydrogen cyanide, emitted in such amounts that it that turned the windshield white as it began to eat into the glass.
Said a Daimler engineer in a Reuters piece, "It was scarcely believable. The most complicated lab tests conducted using the most sensitive measuring instruments around found nothing and all we do is drive a car around a couple of times, open a tiny hole in the refrigerant line and the next thing you know the car is on fire." So Daimler said it wouldn't use the refrigerant, and it recalled the cars it had already shipped with R-1234yf.

Mercedes was set to sell version of Nissan Titan, now Infiniti might instead

Mercedes-Benz Titan. Mercedes-Benz Frontier. Mercedes-Benz pickup truck. None of these things roll off the tongue particularly well. We'd like to think that's the reason Daimler opted to kill the idea of rebadged Titan and Frontier pickups from corporate ally Nissan. In reality, the execution before the Frankfurt Motor Show was due to more complicated issues.
Yes, Mercedes, byword for German luxury, style and quality, would have slapped a three-pointed star on a pair of Japanese pickup trucks that have failed to resonate with consumers in the world's largest truck market. That slapping of badges isn't much of an exaggeration, at least on the outside. According to the report from Road & Track, the truck's front clip would have been tweaked, but beyond that, the sheetmetal would have been unchanged. The interior would have received a more thorough going-over by the team at Mercedes, while the suspension and noise, vibration and harshness tuning would have also received significant attention.
The trucks would have ended up being sold through the light-commercial branch of Mercedes-Benz - the same folks that will happily sell you a Sprinter van - had the deal gone through. Issues arose, though, first with the engines. Mercedes wanted a wider range of powertrains to allow it to tune models for specific markets, while Nissan said it couldn't engineer the wide variety of engines that MB wanted to drop under the hood. For the smaller truck, meanwhile, MB was interested in a hybrid or plug-in variant, according to R&T, although this was also shot down by Nissan.
