@Rikdrt1 sorry to hear about your issue. Did they perform the TSB for the engine? Also did they give you update yet?

This issue happened to me today on my ITS. I was cruising on the freeway for over an hour. There was a shudder and warnings started flashing on the dash. I got to a rest area a few miles down the road and attempted to restart the car. It started extremely roughly, but it came back on - CEL and warnings were still there.

I drove an hour to the dealer in limp mode and they diagnosed it as a fuel pump issue. It'll take about a week to get the part in.

Oh no! terrible news... Keep us posted on the fix.

Just got a call from my service advisor. The high pressure fuel pump came in and was replaced. Yay! Upon starting the car, it was still throwing codes... Low pressure fuel pump issue.

...another week for them to get the part in... *sigh*

Man that stinks!!

@AsianEd Hey did your tech perform this TSB?

No idea. I asked my service advisor and it wasn't something he knew either.

Ask them to perform it and see if the issue goes away. Good Luck!

A bit too late now, one fuel pump ready replaced and one more to go... I'm glad I have a loaner (TLX ASpec), but I'm ready to have my car back.

I got my car back yesterday. High pressure and low pressure fuel pumps replaced. Fingers crossed the issue doesn't come back...

Welp, after about driving 30 miles from since I picked up the car, it threw another CEL. Tank was near empty (fuel light just came on), so I stopped to fill it up.

I stopped at an auto parts store to see if they could pull codes and got P0455, evap system leak detected - large leak. I was a few miles from home and I'm smelling fuel.

Now waiting for the service advisor to call me back to see if they can tow the car to the dealer...

Car has been towed to the dealer and now awaits diagnosis tomorrow. The tech that worked on my car has a hunch on what the problem is.

Apparently the low pressure fuel pump is at an odd angle and a pain to install. He suspects the sealing ring may have become dislodged. It didn't cause an issue right away, so his short test drive didn't throw any codes.

ugh, the fuel pumps probably weren't even the cause to begin with right? Probably software gremlins or air leak somewhere. Hate that you have to deal with this, thanks for sharing for the benefit of all of us.

I got my car back today. It turns out the tech was right and the second issue was a result of human error. There are apparently 5 tabs on the bracket that is screwed into the fuel tank for the low pressure fuel pump. Since the assembly is installed at an odd angle, one of the tabs didn't seat into place when he put it in. That lead to the evap issue and me smelling gas after I'd filled the tank up.

I actually don't know. There's no mention of a software problem in the diagnostic notes. Also, the codes my car threw to indicate a problem didn't match the symptoms in the service bulletin, so they likely didn't go down that route for remediation. My car specifically started with P0087, indicating a low pressure fuel pump problem. Diagnostics showed this to be the case, as both the low and high pressure pumps were operating below spec.

If I were to guess, the low pressure fuel pump having issues led to the high pressure pump failing, as I had to drive about 100 miles to get to the dealer.

Ahh, ok, guess there are some hit or miss physical issues out there. Glad you got it sorted.
