Very odd. After a drive I usually get out and open my rear driver side door as I place my bag in there for work. I have noticed a gas smell from the driver side of the car after a drive. I don't smell it anywhere else around the car. I don't see any leaks anywhere either and the car is driving fine. I don't smell it inside the car either. Has this happened to anyone

 

get the car scanned for fuel system faults

 

W211 had an issue with the tank leaking though I think this was fixed for w212.... anything weird around the fuel cap? Can you pop the seat bottom out in the rear and smell for leaks?

 

I have a basic scanner, i can start with that. and pull the seats this weekend. Is there a HOW to do that somewhere on here.
I dont smell anything inside the car, but its just apparent when standing by the rear door. I always open it after a drive to get my bag. I dont think there is any greater smell when i open the door. Still no visible leaks.
Ill check in morning if any smell after sitting overnight....
just passed 90000 miles...mostly issue free....... I guess hello Hyundai ionic 5

 

**** under the seat...hurray

 

so under the rear seat? Like the w211's?

 

yep. left side is sender , right side is pump
Been recommened to change both, even tho leak is left side

So 211 also does the same?
