Hi everyone, my GLE350 had 60000mile maintenance service at a MB dealer FOUR days ago including Spark Plugs (I attached all service items here). Everything was good before maintenance. However, today the engine light is solid on. I drove the car back to the dealer and the dealer told me there is an issue with some misaligned part of engine. Please see the highlighted "misaligned" part in the attachment. The quoted cost is about $10,000 to replace that part!! Definitely I cannot accept the "explanation" given by the dealer saying "It is just a coincidence that these parts damaged after the maintenance. Not dealer's fault". The dealer also insisted that it is absolutely unlikely that any service items did 4 days ago may cause this issue. But I notice Spark Plugs misplace is a popular reason of engine light on, and it was replaced 4 days ago.

I have 2 questions:
1. Is it possible any service items in the list may cause this issue?
2. If unfortunately it is just coincidence that the misaligned part of engine happens after the maintenance, is the quote of at least $10,000 reasonable?

 

I think it is suspicious especially with a car that has only 60,000 miles and at the oldest is a 2016. I would be getting more information on what in particular is the issue. I have no knowledge of the parts they show as having failed, may be someone else on this site can help on this.

Tell the Dealer service manager, you want to see a regional Mercedes rep to discuss this issue and call Mercedes and let them know.

It personally scares the hell out of me since I have a 2015 that just turned 60,000 .

Keep us posted. Good luck

 

Thanks for the prompt reply. Yes, I will try to talk to the regional rep. Btw, what do you mean "call Mercedes"? Which number can I call? or which keyword can I google for the number? Thanks

 

1 (800) 367-6372

 

This appears to be a cam sensor, both cam actuators, and both camshafts for one cylinderr head. Is this correct?

How common an occurrence is this on the M276 engine?

 

Look the components is called shafts, and unbalanced shafts happened to some GLE350 engine. I am just curious if it is so coincident that it is damaged exactly after the maintenance? Is it possible that misplace of spark plugs may cause this damage?

 

I have the same question. My warranty expired recently, and it is so unreliable.

 

The M276 does not have balance shafts. The explanation does not make sense. It could be a mechanical component has failed, and camshaft is out of position.

It's unlikely that properly performed spark plug change would cause this problem. There is some information on the internet that talks about possible valve damage if spark plugs are not torqued correctly on a direct injection engine. The M276 is a direct injection engine.

It's not impossible that the spark plug change caused the problem, but seems unlikely to me.

 

Hi chassis, thank for your explanation. I am a newbie and definitely learn a lot from you. Thanks

Do you know if it is common to have this issue for a 2016 GLE350 with 60000 miles engine? My warranty expired recently. Do you think if it will be useful to contact MB directly? Thanks

 

Those "SDC" services on your receipts are aftermarket chemicals not recommended or endorsed by Mercedes-Benz. They are purely profit-generators for the dealership with no proof of any benefit to your vehicle. The good news though is that those products often carry their own warranties. I'm not suggesting those chemicals caused your problem- but I would request from the dealer what services and chemicals were used, and what warranty they come with. Sometimes those "oil treatments" will cover damage to internal engine parts ! You will have to be persistent-but it's something to look into for sure.

 

Thanks so much for your suggestions!

 

Read error code from Autozone today and got the following report:
Error Codes Read -- P0019 Crankshaft Position - Camshaft Position Correlation - Bank 2 Sensor B
Definition -- Code P0019 indicates that the crankshaft and camshaft Bank 2 Sensor 'B' position signals did not correspond with each other for a predetermined period of time.

I googled and found there could be many possible causes, and one of the simplest solution could be to replace a bad sensor. It could be some complicated reason. However, I think with just 5-minute examination, the dealer asked me to replace the whole system with $10k is too premature. I will seek a second opinion from another dealer tomorrow.

 

yanmi2007, I don't know how common this is. That's why I asked the question.

It could be that the sensor is the only problem. Do you have other codes besides P0019? Do you have any observations from driving the car? Vibration, smoke from the tailpipe, rough idle, hesitation while accelerating? Strange gear shifting?

 

Hi chassis, P0019 is the only error code. I don't observe anything unusual when driving except it takes a longer time to ignite the engine, saying about 2 seconds vs immediately before.

 

Try observing it over a period of time. Or take it to an independent repair shop and have them diagnose it. It might cost $200 for the diagnosis, but cheaper than $10k.

 

Yes, I am going to take it to another MB dealer and an independent repair shop to collect more feedback.

 

My 2016 GLE350 will go in Feb. 26th for the 60000 mile service (B3) work, so we'll see if any surprises pop up. I have the factory warranty until May with the CPO warranty to May 2021 so I'm expecting coverage for any possible surprises like that.

See where the advise here and calling MB gets you. Good luck!

 

Today I took it to a second dealer who gave the same diagnose results, but quote is only $4700. Got a lower quote of $3600 from a local high-rated shop, and selected the shop. Thanks all for your suggestions and help.

 

yanmi2007, well done for shopping around. What is the list of parts and services they will perform? Please post your results after the work is done.

 

x2. plz update asap.

 

This sounds very suspicious to me. The dealer was the last one , who touched your vehicle. Possibly they’ve caused the issue, directly or indirectly.
I would send a complaint to MB HQ describing the problem with the attached paperwork.
