- 3 driver door

- 2 driver side rear door
- 1 back hatch door

After the 3rd actuator failed, I asked Lexus to look into this to find out the root cause of all of these failures with no luck.

On 4, 5, 6, I again asked but got back that there is over a mile of wiring in the vehicle and it's impossible to determine why.

On number 7, the dealer asked that I call Lexus to see what they can do (these are about $650 each to replace and $750 for rear hatch). Lexus said to go see another dealer...

So here I am, out over $4K replacing door actuators and no closer to finding an answer. Anyone else out there with similar issues? I'm at the point of wanting to get rid of it (although I love driving it).
Is you car tinted? I saw lots of tint places used too much water to do a tint job. The water might run down inside your doors and shorted the electrical system and it caused all of your actuator failed. It's just my 2-cents.

IMO... and stated by others....it does seem moisture intrusion through whatever means is likely culprit ...

If one didn't want to do work them self save yourself some money and purchase the part and find a good independent to spend an hour replacing. It should be considerably cheaper.

Example: Driver Door @ $282.77

Heck... with 3rd party market I wouldn't even bother swapping motor... looks like one can get one for $28 here..PN is the same at least

I was not the original owner of the GS, and I am not the original owner of the GX. I will look into the $5 fix with my mechanic. We have owned an older GX, 2 4Runners, a Tacoma, and I still have a 2003 Tacoma that never had actuator issues. However, I also had a Camry briefly that had a bad body ECU and those those door locks didn't work either. I hope Toyota engineers are reading these threads.
