GLE issues
The Best of Mercedes & AMG
Took 4 days but I have the car back. The old software glitch excuse.




Audi has a discount program for the new e tron electric SUV through Costco, a very rare deal for Audi to discount a new intro in the first year.
I'm so impressed with my GLE that I plan to buy a 53 or 63 in a year or two but not before they are bug free. In the interim I just disconnect the battery every few months.
After reading all the issues above, I have the impression that most of the more serious issues that require a 10mm wrench involve the GLE 450 vice the GLE 350? Is that accurate assessment, or do owners of the GLE 350 also need to carry a 10mm wrench? Sounds like this is more of an issue with 48 Volt mild hybrid system in the GLE 450, and I've notice there aren't a lot of 450s on dealer lots here in national capital region -- I was previously assuming this was due to price.
Also, for any owners of the GLE 350, does the auto start feature use a traditional starter motor to start the engine (i.e., you can hear the starter engage like on a tradition vehicle); or is it integrated like on the GLE 450 and motor generator simply spins the engine to turn it on?

Since the 350 does not have the motor/generator, it does use a more traditional 12V starter and accessories are belt-driven instead of electrically like on the 450.
Good that you're doing your research.
The reason I ask is I own an Infiniti QX60 hybrid. It is a mild hybrid also and has an integrated electric motor to start stop the engine. My one disappointment with the design is although it has an electric power steering pump, the air conditioning compressor runs off an engine driven accessory belt. So when you’re running the air conditioning compressor the engine rarely turns off at a stop. When it does the electric motor quickly spins the engine to restart it with no fuss.
The reason auto makers do this is because they are not required to run the air conditioning compressor for the EPA city mileage test loop. They are required to run the air conditioning compressor on the highway test loop. A less expensive way to get good EPA city MPG test results.

Do you know if the air conditioning compressor and power steering pump are electrically driven on the GLE 350, or they powered by an engine driven assessory belt? I’m under the impression it’s the latter, but I’m not positive. Ideally they would be electrically driven as on the GLE 450, but I’m assuming that requires the 48v system which the GLE 350 does not have.
For now, I’m leaning towards a GLE 450 based on the feedback above, but I’m keeping an open mind.

This link explains how it all works... I had it wrong, I didn't think it used the starter at all but it does...
