Fuel pump issue in 2019 LC
Had a very unexpected problem recently. Just back from a 45 minute each way highway drive. Then when I came from the office, the car was a little slow to unlock per touching the door handle as is usual. Then it was a bit slow to start. Maybe two seconds. A couple of hundred yards away it just plain died as I was pulling into an intersection.
Two passersby helped me push it out of the road, once we were ever able to find a way to get it in neutral. After maybe 15 minutes I got it started and went a quarter mile to a restaurant.
Came out, it started, and promptly died again. In about five minutes got it started and went the quarter mile back to the office. Called Lexus the next morning. The car was picked up within an hour, flat bedded to the dealer in Greenville, SC an hour away. Soon after received a call and they said they had another one three days earlier with same issue. Today, three days later, received a call that a new fuel pump had arrived, was installed, the car is ready to go. They should get it back to us Monday.
Was told the new pump comes from a different factory.
We traded the Bentley in large measure to have something rock solid, able to provide motoring free of concerns.
Of course I understand mechanical devices all fail in some ways, not expecting perfection. These are “earth devices” as Dr Who might say.
But it sure is a bit deflating. Planning a six hour each way jaunt to the coast next week. Should I take our Tundra? Nope, will head off in the sweet Lexus. Will have a greater “sense of occasion” now. We’ll see.

Said I wouldn't eat in the car. That lasted about a month :-( .
Anyway, this isn't the 1st fuel pump issue that has plagued the LC. There was an issue with some of the early 2017/18 ones that could cause one of the fuel nipples to crack, posing both a performance and safety / fire issue. Those owners had to take theirs back for a recall. Perhaps Lexus should schedule a Get Well meeting with their fuel pump supplier. Seems like a fairly low cost component to be dragging down such an awesome vehicle. Or maybe they just need to assign a Takumi fuel pump expert to fully test each one before installing it in the car.

Man that sucks. I guess they don't dyno the same pump with the engine after the engine build. Im sure that once they get the new pump installed, you will be happy. I drove mine from Cincinnati to LA and back with zero issues. Been up to Canada several times. Except for the two things I've been pretty vocal about; Run flats and Brake Pads. Now that those two things are sorted, I'm 100% happy. I have 30K miles on it with 1 year ownership and other than staying on top of the rear wheel steering alignment every 10K or so, its been maintenance free.

My understanding is that the 4S tires are a dual compound tire. The outer 40% of the tire is a sticky CUP type compound and tread pattern, while the inner 60% is a passenger compound and tread pattern that is good in both dry and wet conditions and has very low road noise. My car has about 1 degree of negative camber all the way around, so, in theory, when you tip into a bend, the tire and suspension deforms a little engaging the CUP compound. This seems like a good way to go for the LC. Low tire wear, great cornering for the 1% of the time you are in a 1G turn.
I compensated for the risk that I might get marooned with a flat by buying one of those cheap sealed plastic Apache carrying cases from Harbor Freight. Then I pulled out some of the foam squares and put in a 12VDC portable air compressor, needle nose pliers, a mushroom plug injector, a tire gauge and some mushroom plugs. I got a nail in the tread of one of the PS4S tires the other day (left rear also). I didn't know until my TPMS told me that I was at about 25 PSI when I fired up one morning. So I just pumped it up quickly with my portable compressor went on my way, watching the TPMS over the next couple days to see how fast it was leaking. When the weekend arrived, I took the left rear wheel off in my garage, pulled out the nail with needle nose pliers, reamed out the hole with the T-Handle tool, injected a new mushroom plug, cut off the part sticking out to flush with the tread, aired it up and haven't had any leakage since.
Its certainly true that I drive onto some sites that I probably shouldn't, but it seems like these aggressive tread low profile tires pick up nails easier than the tires on the Land Cruiser. Anyway, the LC's trunk is pretty small, but this little plastic case takes up about as much space as a laptop, so for me, carrying this kit and being prepared is better than tolerating the noisy, rough riding run flats, and tolerating a tire dealer telling me it will take a couple days to get one, and that they can't plug tires for liability reasons or that I need to buy two because the circumference will be different compared to the other side on that axle.
I understand that tire plugs are temporary, but tires are temporary consumable items as well. As long as its not in a sidewall, or a slash, I don't deem it unsafe to put a high quality plug in the tread. If I hit something and rip the sidewall or slash a tire, I'll just pull over, have it flatbed to a tire dealer and will wait for replacement tires. For me, the road noise, ride and performance is that much better than the factory run flats.
I bought them online (about $420 USD ea. with shipping) and my Lexus dealer mounted them without scratching my 21" factory rims and balanced them for about $100 US. I paid extra for the Hunter laser 4 wheel alignment.

Lexus of Greenville delivered the car back to us today, brought it to my office, keys to the receptionist. Can’t say enough good things about their service.
Car started and got me home. Just for fun I’m gonna trust it and go 5 1/2 hours down to the coast for a long weekend.
Greenville told me they had another LC with same issue right before ours. I have info from FB that Atlanta has seen this five times.
Our car had 4000 miles over 8 months when this happened.
So if I were one of you folks who has not had this issue, I’ve sure got to be thinking about this.
And I’ve considered other tires too. There is no feel to the run flats.

I didn't like the road noise and the ride of the RFTs. At about 20K miles eventually I had "had it" and bought the Michelin Pilot Sport 4S tires. This is no longer an issue. Now it rides quiet and comfortable. Its not a Bently, but for a GT car, its a really impressive ride now and it handles much better.

Meanwhile, back in the fuel pump thread ☺️
They got it back to us Monday, we came down to the coast yesterday. Car flawless. Lexus of Greenville were awesome.
I hope this is a very limited issue.
