I'm posting this to see if others have had similar issues or at least if the dealer diagnosis makes sense.

I bought this car new.
All the work on my car has been at my dealer.

September 25, 2023 I dropped off my car. I smelled fuel after I got out from driving.
At first it would dissipate quickly. I wasn't able to find the source.
It got worse and my fuel gauge started to show a loss. I took it in.
The dealer diagnosed the issue as a bad fuel pump, but also the gas tank was cracked where the pump was attached.
They told me that repairing a fuel tank was not something they recommended since they didn't have a good experience doing so.
They found a used tank that they ok'd and swapped out the tank and put in a new fuel pump.
The dealer had the car for a few days to test drive it and check the fuel gauge readings.

After I got the car back, I drove it until the gauge was around a quarter of a tank. When I filled it, it took over 16 1/2 gallons. The tank is 18 1/2 gallons.
That seemed off so I called the dealer and spoke to the customer service rep that I had. He said they drove it ran the tank down a little and filled it. They never ran it down to check low level.
I generally don't let it get lower than 1/4 tank before filling.

Last week, my gauge was slightly lower than 1/4 tank. The needle was not near the red line and no low gas warning came up on my dash. I ran out of gas.
I contacted the dealer and brought it in yesterday.
Today they are telling me the secondary fuel pump (passenger side) must be the issue.

I'm not ready to dump more into this issue.

Does anyone have knowledge about this issue?

Thanks.

Ron,

Sorry and thank you.

 

I picked up my car today.
The dealer gave me a loaner to use while they had the car.
The dealer did change out the secondary fuel pump.
It was tested with a near empty tank and operated as it should, I am told.
For the hassle, the dealer did not charge me for this work.
A bad experience was corrected.

 

The above issue is still happening.
I thought the problem was corrected with the dealer replacing the secondary fuel pump.
I do not normally let my tank get low, so apparently the gauge issue was never cleared up.
It seems to be a Fuel Tank Pressure Sensor problem.
The dealer did an EVAP test and has determined that to be the issue.
I have had Emission System: P145C and P1454 earlier this month.
I brought the car to them Feb 7.

According to the dealer, the Fuel Tank Pressure Sensor on this car is located near the Charcoal Canister. It is not easy to get to.
It would require the rear axle to be dropped again. He said the tank needs to be removed and the rear subframe needs to be taken apart.
The service is recommending not to do this work because of extreme cost and to just drive as is.

Can anyone confirm the location of the Fuel Tank Pressure Sensor on a 2010 TL.
I haven't been able to find this info on the internet.

Yes, you need to remove the rear subframe.
