Engine overheating and metal shavings in the oil of Toyota Highlander 2010: Experience reports and suggested solutions wanted

Hi, I understand your situation, had something similar with my 2007 Toyota RAV4. It turned out to be sporadic faulty communication between ECUs. My check engine light and oil light were also on. The fault was rectified by reprogramming the ECUs and changing the oil as there were metal shavings in it. The noise and overheating was from the wrong information being exchanged by the ECUs. It was definitely a serious problem as the ECUs were sending incorrect signals to the engine and this was causing complications. Hope this helps you! VG.

Hello, that sounds like a really serious problem with your RAV4. I'm glad to hear that it could be solved for you. Do you remember how much you paid to get the problem fixed? And has anything else happened since then or is everything running smoothly now? Thanks for your help! LG.

Hello, yes, it was definitely no walk in the park with my RAV4. The repair costs for the sporadically faulty communication between the control units were pretty steep, I admit. It cost me €955. But hey, what are you going to do if you love your car, right? As for the engine oil contamination, since the mechanic visit it's completely fixed. No more weird noises or metal shavings. So I'd say it was worth it! Since then the box has been running like clockwork, no more problems. Hope things go just as smoothly for you! Good luck, buddy! VG.
