The "auxiliary battery malfunction" appeared, so the aux battery was replaced. Still reappears every couple of days. Also, had the "cruise control inoperable" appear, but the next day it was working. Another day the automatic lights feature was inoperable, Next day it was fine. Do I need a new computer or an update?
Should also tell you that last January there was some sort of computer failure that would not allow the vehicle to shift into gear from park, with a red alert "do not shift gears, service required". Repaired: "M.E. was taking down can bus. Replaced M.E. and profgrammed."

It just happened while driving on the freeway
The mechanic is saying that the fuel tank has only one open hole for fuel plumb. The other hole is capped. We need to replace the tank since we can not just replace the plumb. The car smell gas and will not start without spraying fuel injection. I can be reached at 770-851-1014. Thanks a million!
This has only happened 3 times since owning the car but when I shift from Park to Drive the transmission does not go into gear. The front screen says D but the engine just revs. Last time this happened it took 3 restarts to make it engage Drive.
I have a 2015 E 350. My auxiliary battery malfunction alert came on, so I ordered a battery. I was shipped a small battery about 3 inches long and I have no idea where or if it goes in my car. Any ideas?
