Generally, I would say even without battery coverage there is still a lot covered.

I am in a Canada. The EW is different here. The GM of the dealership could not get anyone to put in an email about coverage on the MBUX system and anything to do with the 48 volt charging system. He told me I had brought up some valid points but said he could not get anyone even at top level people at head office in Toronto to even acknowledge possible omissions of some things that don’t apply to the newer vehicles as it’s old coverage.
He shook his head and said he was amazed people at all levels just kept passing it on to some one else to answer as they did not want to put anything in writing. I said to him I could be faced with a decline on equipment warranty in the new vehicles that are not covered in the existing policy? He said it’s possible that could be the case!
So, it seems at least here in Canada you could pay $4000.00 for coverage and not have coverage on these new vehicles.
GM didn’t know who to talk with next!
Told him to go to Germany.

As opposed to the 48 volt mild hybrid battery (which does not have the power to move the vehicle electrically), true hybrids use high-voltage batteries in 100-300 volt range. So, different animals and "industry standard" does not apply.

Huh??

If you're responding to me, what I was saying is only "high-voltage" batteries have an industry standard minimum 8 year warranty (10 years in California).

I bought the EW with my 450. When my 48V system had to be replaced at 4k miles, I tried very hard to get clarification in writing as to whether it would be covered by the EW. I never got it in writing, but was told verbally it would be covered.

Here you go…I think this covers hybrid and full electric batteries. Since the 48 volt Is considered a “mild hybrid” it is probably covered in the US. Going from memory on Hybrid’s…too lazy to look it up.🥱
”Electric Car Warranties and Exclusions. Most automakers have an 8 to 10-year or 100,000 miles warranty period on their batteries. This is because federal regulation in the U.S. mandates that electric car batteries be covered for a minimum of eight years.”

Well the GLE is not an electric car. I think the distinction between low-voltage and high-voltage (100V - or +) batteries is the key point. I have been unable to find out which federal regulation applies so I can see the precise language. I guess time will tell when the first replacements out of the 4-year warranty happen.

I did some checking and can’t find any regulations either other than an effective date in 2016 and some language about Plug in Hybrids…the Mercedes is labeled as a mild hybrid but is not a PHEV so wouldn’t fall into the category. The regs seem to be pieced out by Dept. with the DOT covering only the hazardous waste regs. I couldn’t find a source for the Dept assigning regs for the battery warranty.
California apparently has stricter regs than the US and in 2026 will add degradation as a factor…the battery must maintain 90% capacity. In the US is it likely that all of the US has the same warranty as that required in Ca?
I can see Toban’s dilemma…different countries…different regs…hard to find answers on a very important subject. I saw one estimate of $5000-$15,000 for replacement batteries plus labor in today’s dollars. Yikes! Since battery technology is rapidly changing it might be hard to even find a replacement battery for an 8 year old vehicle.

Are those the prices on the GLE battery or a Toyota Hybrid?

I think they were referring to Hybrids and full Electric’s.

I got to the bottom of the EV battery warranty regulation - oddly enough, it's the Federal Emissions Warranty, required by the EPA. The battery is considered a major emissions component by 50-state federal standards (although, as you note, California strengthens and extends *some* of the details) — https://www.autosafety.org/wp-conten...nd-Answers.pdf. The most common coverage from manufacturers is 8 years/100,000 miles, but any EV battery is required to retain a certain amount of its original function for 8/80. While manufacturers currently don't have to extend EV coverage any longer under those rules, California is in the process of adopting stricter requirements.

I doubt the GLE's 48V battery falls into the same category as EVs' high-voltage battery to be considered an emissions component.

I respectfully disagree. The 48 volt battery is an integral component of the mild HEV (Hybrid Electric Vehicle) setup of the GLE 450. The fact it is a mild HEV system has no bearing, it uses a motor/generator to recapture energy lost to heat (braking) and stores that energy in a battery to assist propulsion via an electric motor. That is the definition a HEV. The 48 Volt battery also allows engine start/stop and coasting with the engine off on the 450 which plays a huge role in it’s EPA fuel efficiency and emissions rating. That feature was used for its EPA score/rating. It is therefore an integral component of the emission system. The AGM battery by comparison, is not.
