RC Gear Shift Indicator Failure

Esteemed RC owners, I have a vexing issue plaguing my 2016 Lexus RC hybrid. At 44242 km, the gear shift indicator display has become utterly dysfunctional! It's not possible to engage the gears, and the automatic transmission exhibits implausible shifting behavior. The gearbox slips and shifts uncleanly, accompanied by dreadful grinding noises during gear changes. An error is stored in the memory, and the gear selection display in the speedometer is completely without function! Has anyone else experienced this automotive electronics nightmare? Could a defective control unit be the culprit?

I had a similar problem with my RC. Not sure about the year or the engine, but the symptoms sound familiar. Is the display completely dead, or is it showing incorrect information? Did you check the fuses?

The display is indeed completely lifeless, utterly devoid of illumination or any indication of gear selection. As for the fuses, I inspected them with meticulous care, yet found no evidence of any breaches in their integrity. Could this point definitively to a more insidious cause, such as the control unit malfunction?

Sounds like the control unit is the most likely culprit then, given the symptoms and your thorough fuse check. I’d recommend taking it to a reputable workshop for a proper diagnosis. They’ll be able to confirm the issue and give you an accurate quote.

Your insights proved invaluable! The workshop concurred – a defective control unit was indeed the root of the gear shift indicator malady. A replacement, costing 1000€, restored the Lexus to its former glory. I extend my sincerest gratitude for your assistance in navigating this automotive electronics ordeal!
