So this started happening on Friday after my classes ended. I was in the lot when right after I turned the key, the ignition was studdering for a sec until the it completely stopped. After that I thought I completely fu@ked up the engine by forgetting to fill up the oil tank. Lucky me it didn’t seized up But I wasn’t out of the water yet. After fill it with oil I thought I was done but instead it didn’t start at all! On top of that a loud and annoying ringing noise started ring and the front dashboard displayed almost every indicator. I tried replacing the battery and charging it, spraying starter fluid, and swapped the ecu. I can’t figure this out! So anyone here have a good idea what it might be?
IIRC, the warranty extension on this problem was to 10 years from the car's in-service date but I suggest you take your car to a Lexus dealership and confirm. It doesn't, or at least didn't, matter if you aren't the original owner.
10 years past the in-service date is a common period for a warranty extension like this. A similar 10-year extension was recently announced on several expensive components on one of our Toyotas after a class action lawsuit settlement.
Looking to upgrade the head unit in a the car to a double DIN. Would appreciate some feedback on owners who have upgraded and what brand/model they chose. Would like to add a back-up camera as well. Anyone know of a shop in Western PA, Pittsburgh that has experience working on the SC 430?
