New 2010 GX460...but some issues

[SJW66]

Hi all, my first real thread here.

I just purchased a 2010 with only 54k miles. The car is in immaculate condition, has had no accidents and was well serviced by its prior owner...oil changes and rotations every 2500 miles. The drive is great!

However, on the service history I noticed some things that seemed odd for a car with only 54k miles on it...although age could be a factor. What's your take on the following:

1. KDSS - system light/code was frequently registered. At 25k the actuator was corroded, connector damaged and the harness were replaced. Open circuit fault. KDSS light infrequently lights up since then, code registers, then was cleared by maintenance..but appears that there were no further issues. Fluid systems intermittently high and cleared. KDSS lights still go and off.

2. 2 Heat shields were replaced due to corrosion at about 28k then at 48k

3. Rear hatch hinges, pins/piston was corroded and replaced at 20k miles.

Thanks for any insight.

where did you buy it from? possible it got some water from maybe a hurricane or flood or something?

Good thought. I purchased in NJ...but the original owner lived in Rochester, NY. Very minimal likelihood of that...especially in residential areas looking at flood zones...but you never know.

hows the frame underneath look? any other noticeable corrosion?
fyi youre in the gx470 forum. might want to cross post over to the gx460 side of things.

^ My thoughts a well. Just because a vehicle isn’t located in a state with these weather events that doesn’t mean that they maybe weren’t at a location that they were visiting someone.

@SJW66 Do the location of any of the service entries show another state?

Being that far up in NY, with a excessive use of road salt, I don't necessarily think any of that is out-of-the ordinary, especially if the PO didn't keep up on cleaning the underside regularly during the winter (periodic washing). It also seems unlikely that a one-time event (say hurricane flooding) would result in significant corrosion unless it was never cleaned after the event.

Do you have any pics of the undercarriage? If you have a lot of surface rust on a lot of stuff, that leads to it being just general corrosion rather than a specific event. Either way, being that it's a Toyota and has lived in the NE it's whole life, I'd give the frame a really good inspection, then get it cleaned and undercoated (FluidFilm/Woolwax/Krown) ASAP. Frame rust is the #1 killer of Toyotas, and they can look new on the outside but have literal holes in the frame underneath.

Thanks...no other noticeable corrosion underneath. I didn't even realize I posted this in the wrong spot...thanks .

No...all entries for service were in Rochester NY.

Strange. Are there areas in NY that have any flooding like near creeks? Look in the front of the engine bay on the frame rails. Are they corroded?

There are creeks up there...but even on the flood map they're not considered high risk. Nothing in the front. Tried to get under the car today (I have a really bad back) but it appears from the outside there is no visible rust - however, there also appears to be some sort of black coating? I will try and get photos.

If you can get it up on a lift and take pictures. The experts here will probably give you good opinions.

 

[GrizzlyClint]

If you don’t have a lift drive the front up on a curb (in a safe area) and climb under then repeat for the rear. You’ll have plenty of room to take pics.

KDSS accumulator corrosion can happen in snowy/salt regions. In all areas I recommend most drop your KDSS skid…it picks up lots of debris. Just a couple bolts and will likely be packed with dirt and small rocks.

It's probably already been undercoated, which is good. Undercoating on these does require annual touch-ups though, which is what I do on mine.

Another item I noticed wasn't on the car fax...but noticed in the Lexus service records...at 47k the "sun gear" was replaced. So from what I'm reading that is a transmission part...but not sure if it's good that it was replaced and I shouldn't worry or actually had to be replaced at that mileage in the first place! Here is what it says: "VEHICLE GOES INTO GEAR AND WILL NOT MOVE PLEA SE ADVISE ~|~TECHNICIAN CONFIRMED THE CUSTOMERS CONCERN, TECH SCANNED FOR CODES AND FOUND CODES P0705 FOR TRANSMISSION RANGE SENSOR CIRCUIT TECHNICIAN FOUND SUNGEAR FOR TRANSMISSION TO BE INOPERABLE ~|~TECHNICIAN REPLACED THE TRANSMISSION"

Thank you!

Some photos of the wheel wells and under carriage (partial) as this was my long arm under the carriage with a cellphone. It definitely was treated/protected underneath...although those wheel wells could be in better shape.

 

[sedonut]

That's the problem with undercoating, it hides a lot. The undercoating looks new, so you have to wonder if someone was hiding something intentionally. The little piece of the frame in the last picture does not look too bad. I think we really need to see more to give you an opinion.

TBH from the couple of photos you posted it looks like this truck was doused in rubberized undercoating... Not a good sign since the type visible in these photos is the worst kind of undercoating for a couple of reasons:

1. It hides all bolts/nuts/electrical connectors and makes them harder to remove and generally work on the underside of the vehicle in the future.
2. It does not "breathe," which does not allow moisture/salt/debris to escape the metal. Effectively trapping the rust underneath and and rotting the metal from the inside out. South Main Auto on youtube shows a good example of this:

I'd get better photos of the undercarriage to start. I also agree with @sedonut . It looks like the undercoating was layed on especially thick to hide something. My guess is, potential rust scaling/etc.

Thanks for your advice. I'm taking it in on Tuesday to be looked at. In the event that this is like what's in the video...how can this be corrected? Stripping off the rubberized coating, blasting off the rust, repair, and re-coat with something else?
