Reliability Is GONE In This New BMW Engine!

[@xxzmk]

I have only heard about leaking issues from the B48 and B58 Engines. But for others here is a list also with part prices in USA 1. Plastic coolant tank pipe can leak (30 USD) -> Is known to crack and leak even before 60k miles check that one out 2. Plastic Oil filter housing on the side can leak (issue with cracking plastic) (300 USD) 3. The Water Pump can leak coolant and fail (tbh almost any German vehicle has problems with failing water pumps at some point of time) (176 USD) 4. The plastic coolant flange on the side of the engine can eventually leak coolant too (2 Reasons either it cracked or the O ring gone bad) (19 USD) 5. If you realize none is leaking and you have disappearing coolant level then check the cap of the coolant tank, that one can be faulty and leak air. (22 USD) 6. Of course Valve Cover Gasket. But this of course will fail according to how much heat you give it via driving hard. Still this is a wear item and it will eventually fail. (55 USD) So if you have 600-800 USD on hand with tools and you trust yourself in repairs, an used 330i or any 30i Engined BMW since 2015 can be a good purchase if the price is good and all the conditions above are already repaired or met upon. I can say though, a friend of mine drives his 530i xDrive very hard with 0W30 Oil every 6-7k miles and it still didn't have any issues with the aforementioned issues.

The amount of plastic is a serious issue. Aside from pumping in 10s of thousands in repairs to my N55, the plastic deterioration is becoming unmanageable. The engine needs major components replaced at just 9 years old. The car is worthless on the secondary market. The word is out.

That includes the old sheared VANOS bolts migrating to the oil pan requiring a 2 week engine rebuild, the starter started electrical fire burning out every single electrical component in the car, and the typical $2K, oh, every other month or so. It needs a new top, as the shit fabric has disintegrated with dozens of slits, the AC has given up the ghost, the rear main seal is gushing oil, the oil pan gasket is leaking from at least 5 places, requiring disassembly of the tacked-on X straps and dropping the front subframe, and the 6MT pops out of 3rd. The pleather seats are both ripped and thr entire dash is delaminating. I could sink another $30-40K in repairs into it, but its only worth $2K on a great day, so no.

[@urtrippinn4686]

Im a Technician at BMW, honestly based of my multiple years experience when Bmw vehicles have issues its because of the owner. Not maintaining it properly plain and simple.

[@kubastachu9860]

Not exactly true, my brand new 430i has weird issues like random loud banging when braking in the reverse gear or engine being randomly loud for a long few seconds after a start. Contrary to the test drive car, the gearbox doesn't shift quickly, while sometimes even doesn't lock the hydraulic clutch, the issue is with decision time, I press the throttle and it takes a second or two to reduce a gear even in sport mode. It has just wound 2000km on the odometer and I have not revved it over 3k RPM, I have actually treated it with the ultimate care. Not to mention 2020 models lacking rear floor mats. That's a bummer.

[@aa7h911]

I disagree. BMW, much like other manufacturers started quoting ridiculous lengthy service intervals (20,000 miles) only as selling points. Sadly, these lengthy service intervals were and are arguably the cause for many of these catastrophic engine failures such as chains snapping etc. So, I do agree with your point regarding maintenance, but it is BMW's fault for falsely guiding people on maintenance, which they did to increase sales. The second reason behind many of these engine failures is poor quality and engineering. This of course does NOT apply to all engines BMW has or is making, but there are a handful of engines BMW made that are simply poor.

[@bballah9969]

I agree my mechanic told me the same thing. The owners lease them and have them washed and detailed so the outside looks pretty, but when it comes to maintenance he says they want to put in oil that's not recommended for the car and they want to use cheap parts for maintenance. He said once the lease is up and they trade it back in it's a ticking time bomb for the next owner who buys it unfortunately. He told me if you get a BMW either get a newer model and also make sure you get an extended warranty to cover all the expensive and necessary repairs you will eventually have to deal with at some point.

[@bballah9969]

[@henryatkinson1479]

The B46/B48 is more than just more reliably than the N20, its smoother, more refined, and generally just better. Its closed deck, the lifter and injector noise is all but gone, and the new balance shaft has made it almost as refined as the B58. Thats on top of fixing the oiling and timing issues of the N20. I've still not seen any real reason the B48 won't be a very solid engine in the long run. The counterbalance shaft recall ended up affecting a handful of G-series cars, and that was that. None of the early F-series B46 and B48 engines got recalled.

This is a very clickbait title. So far this issue is only affecting 2019/2020 models, and *only* 240 of them. That doesn't mean ALL B48 engines will have this issue. More info below: "BMW is recalling about 240 model year 2019-2020 BMW 330i, 330i xDrive and 2019 BMW Z4 vehicles because the needle roller bearings of the counterbalance shafts may have been improperly installed, a problem that can cause the counterbalance shafts to loosen. According to BMW, a loose counterbalance shaft can cause severe engine damage. About 217 recalled vehicles are in the U.S. and 23 are recalled in Canada. The automaker says the U.S. recall will begin December 6, 2019, when dealerships will replace the engines."

[@TheGamingNorwegian]

It is a legit issue, but it didn’t affect more than 200-300 cars built in 2018 and 2019. And they were all recalled and fixed. So this is not a common problem at all.

Intressting that nobody talk about coolent disappearing, i have a b48 2018 and it has no leak and still drinks after almost one year of driving, i have talked about that problem with my bmw dealer and a answer i got is if you run you car hard it will drink so i dont know if this is normal for a car to drink water even if you dont press it hard on the street. Do somebody have the same issue with the 320i b48? And is it normal for any car to drink water? And need to be filled up?

[@ECPP]

This is a known issue for the b48 and b58 engines but generally coolant consumption comes in one of 2 ways. It either drinks it or leaks it and finding the source of this can be very difficult. Many people see this to some degree in these engines but there is an answer and it should not consume more or less based on level of spirited driving.

It would be great if you could make a video for us where you talk about the things we should change before they fail to make the engine more relable.

[@xorbitman]

Up here in Montreal, Quebec, we would see the 1 series on the side of the road waiting to be towed. Especially in winter. One day a few years ago, my 2012 Infiniti G37xS Coupe had a blown serpentine belt during warranty and needed to be towed to the dealer. While in the cab with the tow truck operator I asked him which car they saw the most often and he told me the 1 series BMW, Mercedes SUVs and the Audi A4, A5 with the 4 Cylinder engine.

[@ECPP]

Great feedback. I have heard similar

[@duncanidaho7494]

the 1 series was quiet reliable especially the 128i.

[@demongaminghd6791]

What about the 2018 bmw m550i is it reliable I’m just getting into bmws

[@bombstar10]

What a load of toss. This engine has existed for years at Mini and is known as being vastly more reliable than the N26/20. Yes the initial B46D (TU) did have some issues up in a few months of 2019 when G20 production was ramping but that’s it really. Trust me, I had one of those early cars and they had a lot of issues but it was almost entirely supplier related to the GXX models specifically. I have heard only good things from others about the engine and trans specifically…the rest of the car is up for debate.

[@MrAchilles113]

b48's in f55/f56 Mini's first year or so were plagued with some engine bearing issue. They replaced the engine in my F56 2014 Cooper S at only 6k miles after it took a crap and the I noted the recall campaign. Now at 80k and the only issues were the notorious engine mounts (piss poor design) going bad, and now the tranny mount as well.

[@roderickbradley3109]

It's a sad day when a Hyundai can outrun a BMW for half the price.

Dont forget they bought 3 BMW guys and a Mercerdes guy to work for them. Note the M design mirrors they copied in new i20 and BMW styled engine covers with Hyundai name on. Why do you think all Research and development and Motorsport take place in Germany

[@Quatt22]

Ummm…how many 4 cylinder Hyundai’s are doing 5.2 to 60 and high 13s in the quarter mile? If you’re referring to their hot hatch, fair..but the 330i is a luxury car, heavier and much better appointed. You make it seem like your run of the mill Hyundai outperforms a BMW lmao

[@dennisfeng6626]

So, I'm wondering, why is it only the B48 that has this issue and not the B58 when the B58 is basically a B48 with 2 more cylinders.

Six cylinders don’t need balancer shafts as they are balanced.

[@antonyh37]

I'm still trying to understand why they cant fix the N20 timing guides regardless of mileage. No wonder BMW brand has gone down the toilet. Now they made a whole new engine with more catastrophic failure. Ridiculous. It's a simple 4 cylinder engine. I would have thought in this stage of the game they would be number 1 in reliability. You shouldnt have anxiety attacks driving these vehicles because your afraid of what catastrophic failure will occur and how much it will cost while making car loan payments. I trust Benz more than I trust BMW. I miss my 99 328i. That thing was solid. But looking back I'm glad i moved back to asian cars. The reliability is unmatched.

[@ECPP]

Thanks for sharing and yes, engineers are very sharp these days so it’s hard to imagine why a lot of failures are unavaoidable

[@DC-dc6ey]

At the very minimum, the registered owner who purchased a new/CPO/used BMW from a BMW dealership should have a 15year/150k warranty on the N20 timing chain guide.

Mark you should send BMW a list of problems experience so they can fix it. Can you make a video of the problems they fixed in the 2.0lt N46 and well as the 2 different versions of the B58. Earlier versions as well how it compares to TU version

[@potatochobit]

Im pretty sure it's big problems like your engine blowing up from rod bearing failure is what gives BMW a bad name. not to mention no oil dipstick. I actually had the electronic oil level meter fail and the car would keep reading empty even though it was just filled.

[@istvan.design]

I have the N46B20 engine and I want to upgrade, I am looking at the B48 right now, even the B38. The N46B20 is a decent engine, it's not a smooth engine, sounds like a diesel and if you don't put new original dampeners it vibrates a lot.

[@davidperry4013]

I prefer the 2000s decade when it comes to BMWs. The N52 naturally aspirated 3 liter straight six is bulletproof but, skimp on oil changes you will be sorry. N52s still have plastic valve covers and intake manifolds but, have metal oil pans and all metal oil cooler. There is nothing wrong with plastic oil pans if it’s designed properly though. Some parts such as the oil cooler are not meant to be made out of plastic unless it’s PEEK which is cost prohibitive or be used in an EV drivetrain or for the transmission fluid instead of the oil in an engine.

[@xytras1979]

Because of this N52 I was about to hate BMW :) ...I will not enter in details ( I want to forget my experience) - in short just check how many updates they did for Cylinder heads ! As far as I remembered around 5 ?! Any way NO to N52 !
