Rodent damage to the electrical wiring harness of my 2016 Lexus RX 350 caused by Lexus using a soy base covering on the wires that attract rodents. Lexus takes no responsibility for the repair that cost thousands of dollars. Not to mention a safety issue. This is a common problem base on all the class action law suits and should led to a recall.

2 Wiring problem of the 2015 Lexus RX350

Failure Date: 04/09/2016

On Feb 9 2016 a rodent had chew the wires inside my engine which the battery/check engine and the all wheel traction light came on. So I drove it to the dealer ship in tacoma fife of wa. So my insurance company told them to replace the whole engine main wiring harness for a total cost of $5372. 38. Everything was good to go, then on 9 April 2016 my check engine and awd drive traction light came on. So I took it to the dealer again, but while driving on the highway I heard chimes going off then all of a sudden it loss acceleration power and loss speed quickly. I was able to manuever off safely to the side out of traffic and down an exit to a complete stop. I turn off the vehicle and started it back on. Then I was able to drive it with a wing on a prayer and made it to the dealer shop safely im glad that I did without getting into an accident. I was told by that dealer that diagnostics found inconsistency report from there computer findings and was told the service manager will keep it to drive it for a couple of days to make sure they can catch the problem. Right now im really concern for my safety, especially it is my wife's car, and if she was driving she would not know how to react in a situation like this. So bottom line im really concern of myself, wife and family safety and need to address this because it can happen again. Please advise on how to move forward. Safety has no quitting time, I bought a Lexus becuase of its high safety expectations, but it aint working for me.
