Anyone have advice for a CPO 2019 e53? The one I’m looking at is a little higher mileage at 47k. I was going to get an extended warranty as well. Any known issues to watch for? Thanks

From personal recent experience on an E63s 2018 with 57000M I would certainly advise a good warranty (watch out for maximum single claim value clause)

Beware the 48V system on this car. Read this site thoroughly. 2018 or 2019 was the first year for this “mild hybrid” powertrain and GLE/GLS owners suffered mightily with MB’s product defects. Read posts on this site - E-Class owners were also affected as I recall.

Either buy a warranty or stay away from this powertrain.

Thank you so much for the info, is 2020 a safer year?

I had a new 2020 for about two years, the 48V was helpful and very much reduced turbo lag as well as made the ECO start/stop virtually flawless. I am just offering a perspective re: the benefits. I didn't have any major problems with it, the I6 engine is also buttery smooth. Just like my E63s with the M177, I've had problems with battery drain when doors are open for extended periods (tint, wrap/PPF or whatever, etc.) But that seems to be a 12V issue.

He's right though, do some searching on the forum. See if that helps inform you.

I would not touch any 48V system from MB. There are reported problems in recent models. Read the V167/X167 GLE/GLS sections.

If you plan to lease and dump the car, the only cost is your time and aggravation when, not if, the 48V system has problems. If you plan to own the vehicle long term, the downside risk to your wallet is high from unknown cost to repair and replace the 48V battery.

Caveat emptor.

I've heard no end of nightmares about this system as well. I wouldn't buy one.

I think the inline-6 is a sweet engine and has a great sound IMO. If you're concerned about the additional complexity of the new electric systems (even though they do have some great benefits), and you're okay going a little older in MY, you may want to consider looking at a 2017-2018 E43.

They are extremely closely matched in performance and are pretty much the same car with different engines. The E43 has the M276 V-6 without added complexity and proven to be a strong and reliable engine without the new electric bits.

Myself, I wouldn't be worried much with an E53 if that's what I wanted, but everyone has their own comfort level. I would have ended up with an E53 myself, but at the time, a E53 was a bit above the budget I set for myself.

Good luck with whatever you decide to do!
