Overheating Issue and Check Engine Light on 2010 Lexus LFA: Suspected Thermostat Trouble

Hey there, I gotta tell ya, I've had a similar problem with my 2010 Lexus LFA. Turns out, my issue wasn't the coolant thermostat, but actual damage to the wiring harness. I've taken the car into a trusted garage, and they found that the wires were all chewed up - likely thanks to a sneaky critter. This was causing a short, leading to my engine overheating and that worrisome check engine light. In this case, the issue was pretty serious. The repair work was a bit complex and time-consuming, because they had to replace the damaged parts of the harness. But the good thing is, after the repair, the car was back to her glory. So I'd suggest checking for possible wiring damage in your garage before blaming the thermostat. Hope that helps! Safe driving!

Hey! Really appreciate you weighing in. Pesky critters, eh? Who would've thought. I'll look into this wiring harness thing. Just curious, do you remember what the damage to your pocket was for this repair? And has any other surprise popped up since those wires were fixed? Safe travels!

Hey! Tell me about it, those mischievous little critters can cause a heap of trouble, can't they? To answer your question, the full repair, including parts and labor for my quandary with the mangled wiring harness, cost me 110€. I know, it can feel quite a punch to the wallet, but trust me, it was totally worth every cent. And good news is, since that whole episode, my Lexus has been running like a dream. Also, turns out you were right about the dodgy Coolant thermostat. I did have it looked over by the mechanic after sorting out the wire issue and yep, it was malfunctioning. Got that fixed and now she's doing just fine. Hope this eases your worries a tad. Here's to hoping it's not a big issue for your ride! Keep it rubber-side down!

Hello again, Wow, that's some kinda adventure you had there! Bar any wild creatures, I'm expecting my bill to be somewhere in that ballpark too. Fingers crossed, though. And it's really reassuring to know your car has been behaving since your ordeal. Might as well get my 'suspected' defective thermostat checked while I'm at it. Guess it's time to dread the trip to the mechanic a little less and look forward to some rewarding results! Stay safe on the road, cheers!
