Engine replacement after 50K miles??
Mercedes is a low quality manufacturing company which means inconsistency from unit-to-unit.

It is either the M256 3.0 inline-6 or M276 3.0TTV6. Either way engine grenade @50k miles is uncommon, and possible for these engines.
If it was any of the current or past three or four MB four-bangers grenade would be the normal and expected ownership experience.

$30k out the door. Maybe some credit for a core return.
HVAC fan is probably a windshield-out and dash-out job. $10k is not out of the question.

I would be looking at finding an independent mechanic that specializes in Mercedes or is familiar with them to get a quote for these repairs. They should be considerably lower.




I agree thought, despite how much we love our GLS, I am not sure that our next SUV will be a Mbenz. They are not doing any thing to earn current owners confidence long-term. I’l enjoy it until the unlimited miles CPO warranty expires in 2-3 years. Will likely switch back to BMW with the inline-6 if they have a PHEV X7 by then.

I can tell not too much people like electric as shown with the Taycan depreciation and I guess it has software issues at some point but EVs depreciate rapidly anyways compared to ICE.
