I think I discovered something on this EW. in Canada. I'm sure it's the same in the USA.

When I read the policy, they referred to comand system, belts ,alternators etc. No mention of coverage on the MBUX system or the 48 volt system with ISG generator etc, etc

Went back to the sales manager and he talked to inside Mercedes regional offices for a week and emails and no one wanted to commit what was covered except what was printed which is way out of date. He was shaking his head no one would say one way or another with the bobbing and weaving. He was frustrated and said to me, you have raised some valid issues here and we deserve an answer even from Germany. So, it's at a standstill now because Mercedes people don't know EXACTLY what is covered and not covered on the new models. The dealers are selling old extended warranties. So, buyer beware and don't let the dealer tell you it covers everything the 4 year covers because it doesn't. it's not in writing on the brochure. By Mercedes not wanted to say MBUX and the whole 48 volt system is covered is a little suspect. I know the batteries are not covered being the 48V AGM and the 48 V lithium Ion battery.

It's been 2 weeks and no further news to my questions or the dealer.

With the stellar reliability record of the one-sixty-lemon (167) why worry about warranty coverage?

 

The reason for my post was to report in the first year of ownership I have not had any issues.

Boy, people are sure touchy or didn’t want me to report something like I did.

Next time I won’t bother.

Toban

 

I am glad that you reported this because I am considering getting an extended warranty for my GLE 350 when I buy it after the lease and I would want it to cover the MBUX system along with everything else.

 

You're right - now that the new model is starting to have a service record, it's showing better than the 166, and reporting better than some of the previous "standouts," which weren't really standouts anyway. Like Toyota, Honda, and "the Gang's" favorite, Hyundai. Now appearing to have more problems than the 167's.
Thanks for keeping us up to date.
But I still want a Factory Warranty on any new model car with all the new Tech onboard.

I'll be watching for @toban 's report on his research. I'd expect all batteries to be covered, but maybe not after 48/50,000 base warranty.

 

I have an incoming 450 and this is something I would like to know as well. Its scary how these companies sell a product without knowing what is/is not covered. What if a car came in for repair now - how would they handle it? (that assumes factory is expired)

I know for sure the 12 V AGM and 48 V Lithium Ion batteries are NOT covered after 4 years. The EW does not cover the batteries.
As a note of interest, my general manager called me last week and told me I could get more for my car than what I paid for it! But, he also said you will have to wait along time and you will not be able to get the options you have currently on your car as they are not available etc etc. Said he had one car come in with a manual passenger seat!

Toban,
Thanks for reporting this. I'm considering the same purchase, so this was very helpful. Disappointing, but very helpful. Sad that they claim not to have an answer for you. I'm sure they have an answer, but they're too embarrassed to admit it... or they're hoping you'll either pay the price or quietly go away. RUDE!

 

But, what happens when you have a claim on the MBUX system or the 48 V system and they tell you these are not covered in the EW policy? Mercedes seems at this point not sure how to answer my questions. General Manager has been getting bobbing and weaving answers. He’s also trying to get a list of items NOT covered. Zero answers at this point. I think they want you to assume everything is covered. Can’t believe other owners haven’t asked instead of taking people’s word for it and write the check.

Don’t hybrid electric batteries have an extended warranty…I thought by law in the US? What does the basic warranty state in the owners manual, is Can different? I would thin MBUX is the entertainment system, so if the warranty cover the entertainment system and “electronics” you’d be covered. If MB specifically calls out MBUX as not covered, then it isn’t and I’d look at aftermarket extended warranties.

 

Ask your Service Manager for better insight.
Some things in the warranty are vague in the marketing pieces, and an F&I person may not know an Internally Lubricated Part from a Battery. That's understandable.
Talk to a person who is in the appropriate area.

 

Texage91:

You are assuming a lot here, think and hope are not answers.. Mercedes ought to be stating it very clear by name what's covered and not covered if they want to sell these policies and so far they are not addressing my questions which I don't think are unreasonable. So, I wonder why no one wants to put their name next to an explanation?

Toban

 

I don’t have the 450 I have a 350.

I looked online at MBUSA, but I couldn’t find anything discussing the 48 V battery. However autobyte claims the hydroelectric batteries are covered for 96 months or 100,000 miles. I’m not sure this is correct, what does paperwork that came with your 450 say?

I also own a 2014 QX60 hybrid and it has a 96 month hundred thousand mile warranty on the hybrid electric components.

Bottom line, I thought an eight year hundred thousand mile warranty on hybrid electric components was mandatory in the US but I may be wrong. I wonder if Mercedes is claiming the 48 V system isn’t a hybrid electric vehicle?

All batteries being the AGM and Lithium battery are warranted for 4 years, period.
The EW after this does NOT cover these batteries.
The 350 model had a completely different electrical system to the 450. This is why by my choice, I charge both batteries from time to time.
The 350 only has an AGM battery. You can’t compare these models.

Toban I hope you achieve a satisfactory resolution.

It will be interesting to see at least 5 separate user reports on this site after 5 years in service and/or 100k miles with the 48V system. Set watches to 2025. Until then caveat emptor in extremis.

 

I believe we are miscommunicating, I understand the difference between the GLE 350/450. The 48V battery in the 450 is used to power the mild hybrid system, the electric motor/generator sandwiched between the engine and transmission, and the electric accessories (power brakes, steering, and A/C compressor). The 12 Volt AGM battery powers the electronics. Thus the 48 Volt battery is part of the 450’s hybrid electric system. The industry standard warranty for hybrid electric components is 8yrs/100k. If Mercedes only warranties the hybrid electric components (which includes the 48 Volt battery) for only 4 yrs/50k miles, then that is only half of the industry standard…which is surprising if correct. If correct, they must not have a lot of faith in the reliability of their hybrid design, compared to other hybrid manufacturers. I would recommend you find an extended warranty that cover these components to 8 hrs/100k miles if Mercedes won’t.

 

I’ve had terrible experiences with 3 rd party warranties. It can be a hassle getting approvals, waiting for adjusters to arrive when convenient for them and basically trying to deny claims for whatever reason. Then there’s the scenario of the warranty company going out of business and you are done and have lost your premium.
I really prefer the manufacturer’s EW if I was to go that route. The lithium battery is worth about $2800.00.

It might be worth checking with GEICO. I don’t use them, but I understand if you insure your vehicle with them, you can get an extended warranty for breakdowns with them for change ($100-$200 more per year. What I don’t know is do they make up that difference in their rates. Maybe someone on here uses them and has an opinion. My insurance company (USAA) doesn’t offer breakdown insurance, wish they did.

 

I am not quite understanding the thread. There is a concern that Comand is covered but not MBUX? These warranties will cover these items even if the wording changes. If there was any issue in the wording it's that Comand shouldn't have been mentioned, rather just electronics. But they called it Comand for the last 20 years...
As for batteries, I am glad they are covering it for 4 years. Consumables are usually not covered and batteries can be damaged by depleting them completely. Other brands will not cover batteries if the battery is damaged by user error or oversight (like storing the car without trickle charger)

 

Correct, and once again I say, you can’t guess with this EW. It’s got to be concise in terms of what’s covered. That is my point from the beginning. I cannot get anyone from Mercedes to actually say is MBUX covered and is all the 48 volt operating system/generator covered under the EW warranty. No one will comment on this. If you guess, you will not be covered for some reason when it comes time to claim.

Toban

 

The M-B EW flier is somewhat vague and lacking on details, but it's only a couple of pages.
Have they shown you the actual contract?

 

No, not yet. The dealer has been trying to get answers as he wants to know also. Everything that is covered is outlined on the brochure and is missing many items on these new cars. Mercedes it seems gas not updated this to reflect the new options on these new cars.

Toban

 

This has a bit more detail

 

I’m in Canada and the EW is not recognized by Mercedes Benz USA. Owner has to pay for repair and try and get a refund from Mercedes Benz Canada. We spend 5 months a year in the USA.
I guess seeing A Canadian policy is the next step.

Thanks for that copy. I assume(!) it's current.
It's pretty clear about batteries, and similar -Apparently they consider ALL batteries to be "wear and tear" items. Also doesn't reimburse for travel interruption.
Other than that, it's good that it's an "exclusionary warranty," meaning that - unless it's excluded, it's covered. It's a lot better than an "Inclusionary Warranty," which means - if they don't specifically name it, it's not covered.

I think the question here, might be whether it's covered under part of the Emissions warranty, which I believe is where Hybrid batteries are covered.
