“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. …”
NHTSA complaint #10854863, filed 2016-04, 5,600 miles“My driver side window turns completely outward when I start my car. It also happens when I lock the door. I have to physically turn it back to the correct position before I can drive. I went to the Lexus dealership, and was told that it would cost me over $1200 to have it repaired. I am a disabled senior, and this is a financial hardship on me. By keep turning the mirror, I am afraid it might break. I don't know what is causing this to happen.”
