Anyone ever have ECU issues on a GX460?
This whole debocle started a week ago when I started the truck after driving perfectly fine all day, and got a flashing 4-low light check engine and stability control off light on the dash. Drove it home, 3 blocks and it was bogging and running rough, almost like in a limp mode.
Took into Lexus dealer the next day and they found P0977 code, “shift solenoid b circuit high”. They traced it to a bad pin and repaired it. They also did SAIP recall while there and told me I have a t-case input shaft seal and front pinion seal leak, but not serious enough to address yet.
Picked up the car, drove it for 2 days, and then while driving, same lights and odd driving happened again. Take it back to dealer and turn it off. They turn it back on and no lights or codes. I leave it there for a few days. And today I get a call saying that they think it may need the engine ECU replaced. They’ve already opened a case with Lexus corporate and have someone helping them trouble shoot the issue.
It’s a 2011 GX460 with 85k miles. I’ve owned it for a little over a year and has a good service history without any standout issues. Recently did a fluid exchange on all the fluids. What the heck is going on here? Any advice or input is appreciated.
