GLE550e Engine Issues
So I recently bought a used 2018 GLE550e with 32K miles from a dealer. The car came with the 1 year CPO warranty which is great. First of all, this is a beautiful driving and running car that is fun to drive. I unfortunately have had the car in the shop multiple times already over the past 3 months. I keep getting engine codes. Finally today they told me not to use electric twice a week because the engine isn't getting warm enough. I'm not sure how I feel about this answer. I bought the vehicle because I only drive 10 miles a day and wanted to use electric. Has anyone else had this type of issue?

Sbinder77,
So let me see if I got this straight… You bought an electric car so you could use the electric car features. But the dealer says you shouldn’t.
It’s absolutely nuts.!!!!!
I would call another dealer and ask their opinion.
incidentally, I came across this possible fix for you in another Mercedes forum. The small battery supplying power to electronics in the car was dead. The problem was fixed once a new battery was installed. It is located in the trunk area… give it a shot?

GLE 550e
I received similar advice from MB customer service relating to the 550e. I am having transmission issues, not engine issues, but the answer is the same (rather defeating the purpose of having a plug-in hybrid vehicle):
"we recommend that you select the gasoline-engine mode before beginning your commute"
"we recommend that you select the gasoline-engine mode before beginning your commute"
