2015 LS AWD, I too just had my fuel pump recall completed last month.... Drove the car Sunday, ran perfect.... Got in to go to work Monday, CEL light, yellow caution light and others, no power and running horrible... My immediate thought was what came lose from when they did the fuel pump.... Towed to the dealer today, just got the call. Mice ate wires from Sunday night to Monday Morning, from what they see at least # 4 cylinder..... I knew wiring was Soy based on European such as Audi (ask me how I know), but I did not know that Lexus also used Soy based.

Lexus.... Really?????? You couldn't have protected the wires?????

 

Are the wires in your LS soy based? Either way mice will chew on wires no matter what it is made of but of course it doesn't help if the insulation is tasty.

 

Honda uses wires impregnated with with capsaicin. Interesting solution!

 

Doesn't work! I posted this before see Shawn Woods on Youtube he laced bait with the hot pepper the mice ate the stuff anyway.

 

Well, I found this article Lexus Class Action
and was very surprised to learn that Lexus actually used organic based sheathing. Tech at the dealer called this right away, before removing intake manifold, so it is pretty common issue apparently.

 

There's a fuel pump recall on the 2013-2015 LS? Sorry I've been absent on this forum for a few months so shame on me for missing this. I just put my VIN in nhtsa.gov for this recall and mine does not come up as having an unrepaired recall. Is it just certain ones?

 

Yeah, I got a chuckle as I read the title and pictured a couple mice with really big swollen bellies, toothpicks, and just a license plate laying on the floor. Ha! I wonder if cylinder #5 might have eaten a mouse when you fired it up?

 

Here's my thoughts on it. As a person if you have been really hungry, and I mean really really hungry, you will eat any food, even what you hate worse. Mice, and any other animal, are in the same situation. So sometimes a deterrent will work and sometimes not.

The problem I have where I live is the damn chipmunks. Fortunately they don't do the damage to the cars as mice do, but I'll leave a car parked for 3 or 4 days and they'll build a nest on top of the engine. And then they're always digging holes.

 

Same where I live, they’re living in colonies and I was able to get rid of them using traps, 15 on one side and 16 on the other side of the house,got all of them and released them on the wild last year, nothing this year.

 

tx - what kind of traps, and what did you use to lure them? I've got chipmunks. Cute, but since my dog has passed, they seem to be encroaching closer and becoming a nuisance.

 

Bought three of them form Amazon, look for the highest rating, you open the door put some nuts and eventually some peanut butter on a small plate ( which keeps the door open ) once they go inside and step on the plate the door closes, and here you are !

 

This is what I use, but sometimes the little suckers eat the bait and don't set off the trap.

Yes they did the same to me in the beginning but I have set it up such that once they step on the small plate the door shuts-up.
