Yes it's indeed those, very surprising still since they are so difficult to service.


Agreed there, even my old beater Jeep gets stuff in time. Probably why it's never failed....

 

But repairs of the 48v system are way less common

 

My 5 series has a button to disable it, and it's persistent. One of the benefits of buying one made prior to March 2018. Cars made after that reset that setting each trip.

​​​​​ I've been on Ford forums for over 15 years. There was a lot of fear of this when the Ecoboost came out and there has always been the occasional post expressing the same fear. But the record has shown that the ecoboost does hold up just fine. They've been on the market for 14 years. The few common issues aren't related to displacement or boost.

​​​​​This fear is based entirely on hypothetical expectations.

 

Well duh, most are too new to fail. Can't repair what hasn't broken yet.....based on what I'm seeing with Audi and Mercedes there will be PLENTY of stuff to fix in a few years with the 48v systems and it's so much more expensive. Great for me!

 

I think you will find that as they age the 48v systems are plenty reliable. Hybrid systems are very reliable.

 

Out of curiosity. Some mild hybrids have belts and starters and alternators. The first start of a 48V 340i is from pinion starter motor. Toyota is like this too.







this is pretty complicated. BMW 340i

 

And those break a lot, the only one that doesn't much is the Toyota/Lex hybrids but when they do it's very pricy. Mostly battery failures though

 

I am just looking on BMW. Here is a mild hybrid.







‘all it takes is a leak here. We lose power steering fluid but gain a new fluid.

 

Mercedes has had water-cooled alternators for 20 years. They're expensive, but they rarely fail. And it's not a new fluid, just one more item in the existing loop.

I don't recall you raising this much concern when Toyota decided the best place to route hot oil under pressure was outside the block through a pair of rubber hoses.

 

What engine? I want to read about it

 

Panameras really do like to drink oil. It’s just part of the ownership experience.

 

My 5 Series is a 2019 and as you said, if you use the auto start/stop it has be reset each time the car is restarted. It's the same with our 2024 X3. It doesn't effect me though as I keep it on in both cars all the time and don't give it second thought. The systems in both vehicles have been improved and even without being mild hybrids are barely noticeable.

 

The 2GR-FE 3.5L V6. I replaced mine preventatively with a revised part consisting of corrugated steel pipes (still a dumb design, but less likely to fail), which cost me about $400 for parts and labor. Tried to do it myself, but the fasteners were in a really bad spot and I didn't have the right tools. Unfortunately, some forum members weren't so lucky. When the hoses fail, they empty the contents of the oil pan onto the ground in less than 15 seconds.

 

Yeah, i generally leave it on. I haven't found it very disruptive, though it doesn't actually shut off that often in my driving. It's 10 miles to my office and that's mostly freeway.

 

BTW. I am not bashing BMW. Just looking and doing research realizing that the mild hybrids aren’t less sophisticated or complicated vs a gas only engine

for Tundra, or Sequoia it would an additional fluid for the hybrid. It would be separate from the main rad. Added complexity to the BMW as there would be no such design if there were mild hybrid parts

‘Is this what you are referring to?


i wonder if my 1GR is like that design
