Reliability




Noticed that the newest issue of CR's car buying magazine shows the "E" Class has dropped significantly in reliability compared to a few years ago. The ratings are based on surveys completed by thousands of actual owners and cover the last three model years. Not sure, but I think E Class was down around 7th for mid-size luxury cars. FYI: Lincoln Continental was first and Genesis G80 was second.




The Genesis is a well made, stylish, less costly car. But, the limited number of authorized dealers is going to be a problem. Their valet service to your door ends after three years.

The problem with their data is that it's a different group of people every year with different expectations.
The Best of Mercedes & AMG




Don't understand. CR does not use looks as a criteria for reliability reporting. They may comment on it when doing new car reviews, but all do that. Current Toyota & Lexus models almost always receive negative comments re: front end looks.
Are you asking about new car recommendations? In that case, "S" class and Lexus 460 were both best cars in luxury class. Honda, Toyota and I think even Hyundai, Mazda, Nissan show up in other categories and some are made in Asia. Suburu is a perennial best car.
I would have to do some research on most reliable cars. Generally speaking that is going to be Asian all the way..
This particular topic was for mid-sized luxury cars and only Continental and Cadillac are American makes.




Its been for years that when MB needs 3 fingers to close the door- that gives him low ratings becouse that is not expected.
Nissans who need knee kick to close get top ratings on other hand. Nobody expect them to work smoothly.

I started driving Mb back in 1997 when we bought new ML320. The break-thru technology was having bad reviews left and right. Probably in those years only Yugo could generate worse reviews than ML.
But I order mine in basic trim. No sunroof, no GPS, no leather, no power seats. So the car was staying with the family for 13 year/130k miles and all it took in those 13 years was about $300 in failed parts. Make it 25 bucks a year to upkeep MB plus regural service, where I kept for long years dealer's receipt $80 for service A (MB used dino oils at the time)
At the time we had a snow-skiers team where we have been sharing our vehicles. Friend bought at the same time Nissan Pathfinder.
The SUV was having much smaller legroom than ML. It was much lounder, was bottoming out on freeway bumps with 4 guys in it. Than it was guzzling much more gasoline with less HP. and it took really good slam to close the door.
So what reviews Nissan got? All the best and it was recommended as top of the class.

Also the comment about having different groups of people filling out CR survey at different times makes no sense. Statistical processes can correct for bias in the sampling and correct for errors so long as the sample size is quite large. That is why CR won't publish data on some cars because they don't have enough to clean the data.
You all (and I) have a behavioral character called confirmation bias - meaning that we rationalize the expensive choice we made to purchase our cars. Let's admit that first.

You think statistical processes can correct for some bias, but sometimes it's hard to get a good figure on it. Just look at the last presidential election and the polling. Historically it has been way off even in the past. It's just too small a sample size in this particular case to have any meaning.
Plus when you buy a car that only sells 7-16k, good luck finding 3rd party manufacturers for parts or finding parts in the junkyard or on eBay. We're stuck with OEM on lots of parts on MB as it is just because of a limited market.




Quiet and smooth because of 400lbs of foam doesn't hold a candle to quiet and smooth because of engineering. I highly doubt anyone at consumer reports knows how to hang a picture themselves, mind you actually understand mechanical/electrical/structural engineering.
They mail out the survey to all their subscribers so it's pretty accurate (I'll say 80-90% accurate). My friends and I had Honda Accord and Acura TL that was recommended by CR, and other car magazines(car and driver, motor trend, Road and track) that had transmission issues that were never recalled. One even had 2 new transmission in 3 years, after that, she got rid of it fast.

They buy their own car for testing, not using the press car for testing. In fact, they got one of their subsciber's Testla model 3 to test out earlier this year since it was hard to get a car(buy it) when testla has production issues. It was their brake testing that force Elan Musk to apply over the air update to all testla within a week of the report. I really wish MB will have OTA updates in their future generations so we don't have to go to dealer for updates. Yes, I'll gladly paid the $100 annual data connectivity fee that testla charges that include map updates and new functions added.

Regardless, Consumer Reports has a defined standard for response requirements. If they do not receive an adequate, statistically valid number, they do not publish the results.
I don't understand what you meant by "Plus when you buy a car that only sells 7-16k, good luck finding 3rd party manufacturers for parts or finding parts in the junkyard or on eBay. We're stuck with OEM on lots of parts on MB as it is just because of a limited market."
Your post only refers to Hyundai as selling 7,000-16,000 vehicles, but then you say "we're stuck with OEM on lots of parts on MB because of a limited market." Your post says 50,000-60,000 "E" Classes sold per year.
Are you saying you prefer to find your M-B parts in junkyards or on eBay? As for Hyundai, there are a lot of third party sources for parts and service for these vehicles.
As for M-B, many of the OEM parts on M-B's are actually manufactured by a third party to begin with. I remember when I had a Saab 900 Turbo and it was hard to start, especially in the cold. The regulator was actually a Bosch part and was exactly the same as on M-B and BMW and probably other European vehicles. Some parts may say M-B, but same one is stamped BMW, Volvo, VW, Audi, etc. when manufactured.
Regardless, a Mercedes-Benz, especially the "E" Class should be at the top of the list for reliability not near the bottom. At one time, it did rank number one (maybe two) for reliability and for years was M-B's most reliable vehicle. The Best or Nothing.
Personally, I'm very skeptical of Genisis or any Hyundai/Kia. My experience with family members owning several (though no longer due to their negative experience) is that they are decent cars until around 60-70K miles and then they fall apart. Their advertised 100K warranty covers almost nothing after 50K.
