Got our CPO 2019 G550 almost a year ago with 54k miles from a large dealer in the east bay here in CA. Really enjoying it with just a couple things I'm not crazy about. First is the sometimes overactive perimeter sensors and also how it's not a touch screen. It’s been solid overall until some recent issues which were not too surprising considering the miles. About two months ago a yellow CEL went on but went away. It came back on when my wife was driving it about two weeks ago but this time the engine stalled and she couldn't get to highway speeds. We had it towed to our local dealer and also scheduled to get the 60k mile service which was almost due.

CEL issue was due to an engine coil failure that was fixed under warranty. These are apparently covered well after the CPO warranty expires. 60k mile service was $1585. A faulty gas door latch was also replaced under warranty. Dealer also recommend a new battery for $710, two new front tires for $1338, and new front brakes and rotors for $3231 which I passed on and went to an indy for a second opinion.

The indy tested the battery and thought it was still fine and was likely recommended for replacement due its age. The battery has never given us any starting issues and we drive it within an hour from our home so we didn’t change the battery. New front tires plus alignment was $1200 so not too far off the dealer quote. I needed 285/45R21 tires because the previous owner swapped out the stock wheels some AMG wheels. Those larger tires are just a lot more to replace. Both front pads and rotors needed replacing and wast $2k at the indy for OEM parts. The rear pads and rotors on my 2019 Range Rover were $1600 at an indy a few months ago as my reference.

I also asked for a quote from the original dealer to extend my CPO warranty, $8k for 2 more years. Have a few more weeks to decide but I will likely pass.

So that’s about $4700 in out of pocket cost for the first year and 8k miles. A bit high for a CPO vehicle, but to me, not bad for a G550 with mileage that was in the range when tire and brake wear and tear should be an expected expense. My wife also shuttles our youngest son from Marin to the SF five days a week for classes, rehearsals and performances which eats up brakes and tires. Last year the new g-wagon’s finally dropped to reasonable prices and I was good with buying our CPO for $115k with the color combo and wheels I really liked. Thought it was a perfect opportunity to find out if this one was a keeper. Had a 2008 G500 which was the car I owned the longest at the time because I liked it so much. I love how this G550 looks and how an ordinary errand feels a little more special which are two key factors in what makes a car a keeper.

Glad to hear you’re still loving it! Hard not to, it’s a special truck. Appreciate the detailed maintenance write-up. With so many people trading in every couple of years, we don’t see many high-mileage posts. My 2021 G550 is just shy of 60K miles, and aside from a piston misfire in the first year, which was fixed under warranty, it’s been running smoothly!

$1585 is fair if it included an oil/filter change, brake fluid replacement, spark plugs and fluid changes in all 4 gearboxes. $710 is steep for a battery you can buy for $225 at any auto store and install yourself in 30 minutes (although it does weigh ~60 lbs.). I've never replaced only 2 tires and would not advise anyone to do this. My '19 G550 has its original 20" wheels and a full set of tires + installation is about $1200 (and includes free balance/rotation every 5K miles). My brake pads at 24K miles are still at 9+ mm (12mm new / 3mm replace) and rotors are still fine. Brake wear is all about driving style -- some burn through a set in 25K miles while others see them last 100K. If one set is at 3mm warranting replacement, the other set is likely not far behind, and I'd do all four. Rotors are an oversell -- unless warped or scored, they're fine with a new set of pads.

Hoping that's it for bigger maintenance for a couple years. Looks like we both have a white G550 with the night package. Here's mine from I first got it. Wishing you more trouble free miles.

The battery and brake quotes sounded way off. It was the front right tire that was a lot more worn down. The other tires looked fine as they should after only 8k miles from being CPO'ed. Not sure what happened. It's my wife's daily which she replaced a Honda Pilot we put 68k miles on since new with no brake work ever needed. Wish I knew how to inspect rotors but I'm at the mechanic's mercy on that one. G wagons and Ranger Rover are over 1000 lbs heavier than a Pilot so that doesn't help with brake wear. Wasn't worth it to me to have to make another visit for brakes if the rotors needed replacing after all. Possible 25% increase on imported parts was on my mind too.

Great to hear. I’m in the market for a 21-23 G550 and it’s really hard to find any sort of long term/high mileage info about them. Seems like the first owners usually trade out around 10k miles. This would be a daily driver for me, ideally take it to 200k miles or beyond.

Anything you’d recommend looking for or to avoid? Right now I’m seeing 21s in my area (East Coast) with around 10-20k miles for $115-130k which I think seems relatively fair.

I think as long as you’re getting a CPO with a warranty and/or buying the extended warranty then you should be good and it’s more about finding one with the color combo you want and ensuring the vehicle’s paint and interior are in great condition.

Yeah that’s basically where I’m at. Biggest constraint seems to be finding the upgraded quilted leather interior, especially in my preferred color (beige). I have no idea why so many of them have the basic interior, the upgrade wasn’t hugely expensive especially considering the cost of the vehicle new.

This is pretty common with the G550 at its price point. Once you start adding all the options, it becomes hard to justify not just going for a G63 instead. That’s exactly what happened with my 2024 G63—I initially built a fully loaded G550, but when I saw how close the price was to a G63, I jumped on an allocation as soon as my dealer called.

It's been another year and I just heard back from the indy Mercedes garage I dropped it off for its annual service. This was my wife's daily driver the previous year and became my daily driver last year that I share with a couple other cars. I'm now at just after 70k miles after putting on about half as many miles, just under 7k miles, as my wife did the previous year. I had zero issues with it last year and so far am glad I didn't extend the CPO for two more years for $8k. Besides the service A, my indy recommended doing a brake flush and new battery. That should bring the total service for the year to about $1k, not bad for such a fancy car.

I'm always checking to see if any newer G550's pop up nearby with a warranty. For me in CA, sales tax will likely be at least $10k if I got another one with no sales tax credit on any trade-ins. So long as this one stays reliable, it's going to be a keeper.

Also update on my 2019 Range Rover with around 60k miles, last fall the transmission died. The lifetime transmission fluid apparently got low and killed the transmission. Thankfully the extended warranty from the Mazda DGDG dealer I bought it from actually covered the $13k repair that took over a month. Traded it in for a new 2025 Land Cruiser shortly after it was repaired. I think any gwagon owner would really like the new Land Cruiser. Looks great, same high driving position and visibility.

Good to see you sticking with the G.

Also good to see a report from someone who elected not to buy an extended warranty and was happy about it, in retrospect. Insurance products like warranties generally do not pay out as much as the premia cost. In your case it worked to your favor, congrats!
