I own a 2002 SC430. I just brought it into the Lexus dealership because most of the warning lights were on, speedometer was not working, steering was sluggish, skid control wasn't working etc etc. It felt dangerous to drive. It only has 57,000 miles on it. It was just brought in for a full service three months and 360 miles ago. They said it also needed some engine repairs at that time. They did engine work and the service and we got a bill for over $2000. The dealership told me that the current problem is due to a bad ECU and it would cost $2,300 to replace it. They told me it has nothing to do with the engine work they did and it is not covered under any warranty. Is it possible that the ECU could have been damaged when they performed the engine work? Also a few years back the dealership installed new engine mounts. Could that have caused the problem with the ECU? Also can I purchase a second hand ECU? Thanks for any information you can provide me.

Ask them which ECU?
Get a part number from them since they are going to replace it.
Then go online and check prices.
eBay is good place to start.
BTW, this car has several ECUs.

Indeed!

Depending on options, can be 28 ECU's (IIRC).

Getting a replacement on eBay is an option. Personally I would get my old one repaired since it might be tied to your vin number. You can find repair specialists in eBay also
