Engine light
Dear All,
First of all let me start by saying i love my car ! But i have some issue with it .
2 to be exact.
The first one is my Engine light goes on every time my tank get to almost 1/2 tank ? Why ? I already took it to the dealer, i'll have to return has i was told it was a gasoline issue . I only use 93 octane since new, only drove 2922 miles so fat since April 2014.
The second issue is the squeaky breaks !!! It is really annoying, i was told that is because it is a sport car .
Well i drive also at work a 911 a CLS Gullwing and no SQUEAK !!
I know the price is way different, but still why should i feel like everyone is looking at my car when i pull up to a red light !
but even with these problems i still love driving and being in the car , the finish is great !! better than Porsche , i just wish i didn't have a RED light on my dashboard and noisy break pads.....
My Best,

I'm no expert, but I doubt that CEL is caused by bad gas. You live in an area where there are many good dealers. Find another one. Finding out exactly what code(s) would be helpful, too.
A few stiff stops should clear up the squeaky brakes.

Get a dealer who will take the time to fix it! As you said it should be tripping a code, which one!
I had to bed in my brakes to solve the squeal issue when I got the car. 4 or 5 hard stops from ~60 to ~15 mph then let them cool by driving 15 minutes. Best not to stop until they are cool. Just need to find the spot to do it. After that was done no squeal at all for over a year.
Just switched my brake pads to Carbotech 1521’s to solve the Z51 excess dust problem. Bedded those per the Carbotech recommendations. Not one squeal and very little dust. I believe they actually stop better on the first stop when cold. Feel great, very linear modulation.

On both counts.

Has far has the dealer i'm with Chriswell and my sale person was no there than famous Mke Furman , so for the experience i got iwas more than amaze..Never got treated so well in dealer in my life !!
They told me to run the car with a clean tank of gasoline to see if the light will pop up again ! and it did, so once the snow clear i'll go to the dealer again and hopefully get it fixed or else they can take my lemon
Thank you all for the advice !!!

Great advice from Jerry.
FYI there is a TSB for the squeaky brake issue and they will replace them under warranty.
Just had mine replaced and the squeak gremlins are gone

Saw an interesting comment about who uses E85 since many cars cannot use it, like the Vette. Folks filling up a rental car when they bring it back!

not good news
I had a somewhat similar problem, the diagnosis was the pickup, fuel sender units had to be replaced, same problem with my C-5. This is not a pretty picture, to get to the sending units they have to drop the gas tanks, which requires dropping the entire rear drive line for access, took over a week.
Good luck,
bill

I had a bmw that did the same engine light issue. Apparently cars sold in US are required to have a system to check for integrity of the gas tank seals. When the car is started, an air pump pressurizes the tank. If the tank doesnt hold pressure the engine light comes on. The problem can be caused by:
1. Bad/weak pressurization pump
2. Faulty pressure sensor/sending unit
3. Actual leak
4. Bad gas cap seal
I would spend a few bucks on a gas cap before letting a dealer take my car apart.

Check the seal for small obstruction/dirt that might hold the "flappadoodle" slightly open enough to cause improper seal.
