2010 Lexus LFA Experiencing Electrical Malfunctions: Seeking Advice

Hey there! I had a similar issue with my 2010 Lexus LFA a while back. It started with these unusual electrical gremlins, just like what you're describing. After racking my brain and poking around in the shop, turns out that the problem was with the control unit—it was a defective cable connection. Additionally, there was an issue with the connection to the BUS system in my car. Here's what you need to know about it. This might seem like an electrical voodoo, but in reality, it's not as complicated as it sounds. Essentially, when you've got a faulty connection from the control unit to the BUS system, it can cause all sorts of intermittent faults and weird behavior, ranging from minor things like an occasional warning light to even affecting the functionality of things like your navigation system. It's a genuinely serious issue in the sense that these unusual malfunctions can make driving unpredictable until it's sorted. And also, if it's left unchecked, there could be instances where the control unit might fail to communicate with other systems in the car. This could consequently lead to an increase in mechanical wear. So definitely something to get checked out. On the bright side, it wasn't as catastrophic as it sounded. All it needed was a proper diagnosis to find the problematic connections, and then repair or replace them. The challenge was more about finding the faulty parts and less about fixing them. Plus, the inherent beauty of driving an older model was visible. These cars are easier to work on compared to the latest models. Good luck, and I hope this helps!

Hey, thanks for the breakdown. Sounds exactly like what's going on with my LFA. This trouble connection seems to be the prime suspect. Just curious do you remember how much it cost you to get it all sorted? Did you come across any other problems with your LFA since you got this fixed? Cheers!

Hey, no problem at all! Yeah, I did manage to get it sorted. My mechanic was pretty thorough with it. He fixed that control unit cable connection issue and got everything back in working order for about 155€. Not too bad considering the headache it was giving me. And honestly, it's been pretty smooth sailing ever since for the old Lexus. That dodgy connection was wreaking havoc, but once it was sorted, it let the control devices finally have proper chit-chat. So, touch wood, haven't had any more electrical mysteries cropping up. Quite the relief, I tell you! Good luck with your LFA, hope it's just as simple for you!

Cheers for the insight, really appreciate it! 155€ seems quite reasonable given the kind of problems I am experiencing now. It's giving me a bit of confidence too because I was fearing something more expensive. Better get my LFA into the shop soon then, and hope the cause is just a dodgy connection like in your case. Fingers crossed that it is the end of it and I can enjoy a hassle-free ride. Will let you know how it goes. Thanks again!
