From what I read about Hyundai and Kia 100K warranties (and what kept me away from that brand), that it is all good until you have an issue. And if something happens they will ask you for documented records for every recommended maintenance item, in order to ovoid the warranty repair. I do not know how true it is, but I read a lot of complaints with this happening, and a price difference was not sufficient for me to take that risk.
EV's should have less issues mechanically, but I would imagine electrical issues will increase. To me EV's are too expansive at this point due to battery costs, and I do not see the price going down until non Lithium Ion technology is widely available. Battery cost almost double in last year due to high demand in battery storage needs resulting from Wind Power project that are started all around the country.

There was an article today in WSJ for "Electric Vehicles Took Off. Car Makers Weren’t Ready - More buyers are lining up for EVs, catching car companies flat-footed and triggering a race for more batteries, factories and materials":
https://finance.yahoo.com/m/9d76f738-8f0b-3868-9887-5029a9742d96/electric-vehicles-took-off-.html

"U.S. buyers paid about $66,000 for an electric vehicle on average in July, up 28% from a year earlier, according to research firm J.D. Power. The average price paid for non-EVs rose 12% in that period, to about $45,000."

To me it is the charging networks and also the infrastructure which is not here yet... NYC will be switching to EV buses and they are saying electricity needs for charging 600 buses is equal to a small city supply amounts....

Vladimir Livson

And yet NYS just killed two new power plants in or around NYC. Sore topic.

Lots of reasons for and lots of reasons against EVs. But it’s a rapidly changing immature technology. Costly long term decisions are being made that may end up obsolete before they are fully implemented. Inductive charging is already being tested that could quickly replace rapid plug in chargers.

I think I‘ve hijacked this thread which was originally about P219x errors on M260 engines.

2024 C63 comes with 235 hp per liter 4 cylinder engine.... Even yahoo article says "That's all, folks!":
2024 Mercedes-AMG C63 - 2.0-liter turbocharged internal-combustion four-cylinder makes 469 hp before any hybrid assistance.

I got the GLB250 back today. The time estimates for parts and repairs were perfect. The car runs perfectly so we put it back on our typical 100+ miles a day routine. Time will tell.

While they had the GLB they did whatever updates were available. Notable is the latest transmission program. The 1-2 upshifts, which were never bad on mine, are now almost imperceptible.

I’m back in the satisfied category (that’s a grade of C), but I will still look into extending the warranty.

Vladimir Livson

Glad things worked out in the end.

Odd Piggy

Yes. Thanks.
FYI—
The service manager says that low speed pre-ignition did not cause the problem. It is a defect, changes have been made, and it should not happen again.
He said that pre-ignition could happen if premium grade tier 1 gasoline is not used, but the first error is usually misfire. He said the Ford Focus problem is quite different from the GLB/GLC ones and that Ford solved the problem on later engines.

As I said, time will tell.

Had my 20k, schedule B service performed on my GLB250. Parked the car for two weeks and the check engine came on. Went to Autozone and the error was P219E, as three errors: stored, intermittent, and permanent. First time I've read about an issue with cylinder 3 air-fuel ratio imbalance. Car runs very rough when cruising 28MPH at 1800RPM. Dropped it off at the dealership today, waiting to see what comes of it.

Everything I've read about has been the P219C error, anyone else have experience with the P219E error?

Service advisor informed me the cylinder head is bad. He stated theres a known fault in the head itself creating a vacuum, so its not getting the correct pressure to operate. He said Mercedes have revamped their head design to fix and prevent this issue from happening again. A new head is on order and is about a week out. I guess time will tell.

Odd Piggy

Scroll down a bit. I had same problem with the same explanation. They must be making repair parts available as mine was done in about a week.

From A-35 new cylinder head post (https://www.aclassclub.co.uk/threads....19533/page-15), MB Technical Service Bulletin TSB LI01.30-P-072328 was published on 09/30/2021 for M260 or M264 engines:

https://www.tsbsearch.com/Mercedes-B...0-P-072328/118

Supposedly they fixed this issue per A-35 postings, but it looks like it is still happening on 2022 models as below GLA fix. I talked with the MB service and he said they know the issue as a part problem and it takes 3 days to repair under warranty, but they have to check the car to make sure that is the problem so they can order the parts. He said it is happening more on GLB250's, but then the sale ratio might be 1/10 between GLB35 to GLB250 also...

I've been keeping an eye on this thread as my wife's 2021 GLB250 with 19k miles threw a P219C code about 2 weeks ago. It came and went 3 times, never flashing. The only symptom was slight sputtering below 2k RPMs. Made an appointment for the vehicle, and got a call this morning that the cylinder head needs replaced and gave us a week to 10-day window for completion.

My 2021 GLB 4 matic engine light came on about a week ago but then went off. Then today the engine light came on permanently. Took to auto zone to run code and it came back as a P219C. Glad i called mercades a month ago to get an appointment as it idled rough a month ago. Taking it in Friday.
It sputters, and then it also shoves you forward when braking sometimes.

Thanks for posting this @sarahpara . Please let us know what the dealer finds.

Major engine failure is hardly a glitch.

theskippertooo

Wow. Just found this thread but already posted a new one on code 219D. I have a bad feeling Im going to have this same issue and need a major repair on my 2020 GLB with just over 30k miles. My issue so far has been an intermittent SEL and I was able to finally read the code which comes up 219D. I guess I will be making a trip to the dealer..smh.

Serhan

P219C: Cylinder #1 Imbalance Error : https://dot.report/dtc/P219C

P219D: Cylinder #2 Imbalance Error: https://dot.report/dtc/P219D

So it looks like it is the same error, on different cylinders. Also you should check the post on warranty extension on GLB:

theskippertooo

Took my GLB in to have them diagnose the SEL. Over the phone I was told they wouldn't diagnose if the SEL was not on when I brought it in, so I asked her if the codes were stored and she was able to pull up the info remotely. She saw the 219D code and allowed me to bring the vehicle in. Low and behold, they are changing the cylinder head. Currently waiting for parts. I was estimated roughly a week start to finish but I can see this taking much longer since they don't even have the parts yet. just hit 30K miles and head needs replacing... insane. Luckily they sent me off with a loaner.

wireman218

Has this issue been corrected on the 2023 GLB engines?

Serhan

Warranty extension letter says for 2019-2022 vehicles:
https://mbworld.org/forums/glb-class...nder-head.html

So I assume MB corrected the issue on 2023 GLB....

Odd Piggy

Stay posted and I’ll let you know. We also have a 2023 GLA250. Same engine.

FYI - I found this pdf (dated Aug 4 2023) on the nhtsa.gov website:

https://static.nhtsa.gov/odi/tsbs/20...41534-0001.pdf

That NHTSA piece just confirms my fears about the very vague Extended Warranty letter from MBUSA. They are explicitly NOT covering the failures that most of us are getting because P219A-B-C-D DTCs are not part of this warranty. We've got 3 247s in the local fleet and both of the 2021s have failed with P219(x) MILs. One of them nearly made it past the 50k basic warranty. So if they fail again at 55K-60K miles, then this doesn't cover them. That's simply unacceptable.

I hate to sound like the haters, but the SUV we just added to the fleet is a Hyundai. (It replaced a Cadillac, not a Mercedes). It's a very nice little SUV and has most of the features that you find in the GLA and GLB. The dealer experience isn't nearly as good, but the pocket book pounding is certainly much lighter. Since the Korean 4 cylinder engines are covered for 100k miles, if the M260s puke up their guts after the basic warranty gives out, they'll just get written off as junk rather than forking out $15k-$20k for a bandaid fix, and replaced with Hyundais or Kias.
