I’ve got a 2011 E350 here on the West Coast, and man, the navigation system is a trickster—keeps acting up. Also, I’ve been hearing some weird noises from the engine. Seems oil leaks near the valve stems. Anyone else dealin’ with these? Spent some time under the hood but still a mystery. Guess it’s those fancy German cars, eh? 
I’ve had an '11 E350 in Toronto and let me tell ya, the tranny’s a nightmare! Acted up crazy after 50k miles. But other than that, it’s a pretty sweet ride. Power management system quirks too, but half the owners struggle with that. Keeps me busy at the shop, but hey, that’s why I fix cars!
I had a 2011 Mercedes Benz E350 here in the States. Noticed a few issues: some folks complained about power steering problems. Alignment got wonky after a couple yrs too. Always running into oil leaks over the years, too. But love those leather seats until they start warping. Guess there’s always a trade-off with luxury. Still a sweet ride though, when it’s in tune!
I’ve had my fair share of trouble with my 2011 E350 here in Canada. The transmission was a real pain, kept slipping gears, and the infotainment system would randomly freeze - super annoying! Some people swear by lubing the pan, and it kinda helps… for a while. Also, the fuel efficiency isn’t what it’s cracked up to be, especially in the winter. Great ride, but gotta pay extra attention to maintenance. Anyone else here had similar issues, or got fixes?
