Specific symptoms reported on the 1992 Lexus SC400
Recalls 1
Service brakes, hydraulic: foundation components
- What is wrong
- The anti-lock brake/traction control computer logic program was incomplete, resulting in the trapping of brake fluid pressure in the rear brake lines. Failure to release the rear brake line pressure causes a condition where brake pedal application results in activation of the front brake only, and continual rear brake drag.
- Risk
- Failure to release the hydraulic pressure in the rearbrake lines causes the rear brakes to "drag" and a condition where only thefront brakes are applied when the brake pedal is depressed by operator. Thisresults in early wear of the rear brake lining, increases of stopping distances,and possible loss of vehicle control and a possible accident.
- Remedy
- Replace the defective anti-lock brake/traction control computer, and if any brake system is damaged from the defective operation of the anti-lock brake/traction control system, repair the damage at no cost.

What 1992 Lexus SC400 owners say
Most recent owner complaints, unedited.
Unintended acceleration, my 1992 lexus sc400 accelerated to nearly 90 MPH on a 50 MPH rd. After going through a yellow light. When I was near the speed limit of 50 MPH I let up off the accelerator but the car was climbing in speed as if I was still on the accelerator, I applied the brakes twice and each time I did it felt like I was being pushed from behind so I put on "n" only to hear the RPM's rev really high. I don't have floor mats but I had the car serviced earlier that day but when I took it to the automotive department of the college I was attending they found nothing wrong, it has never happened again since then despite the fact I constantly take my foot off the accelerator to see if it slows down. There was no crash and therefore no injuries.
1. The last time my car had sudden acceleration was at a service station when I shift the gear from "d" to "r". I hold the brake real hard and shifted the gear in "n" and the engine RPM back to normal. The whole event caused about two second and almost hit a car behind my car, smoke was generated from tire spinning. 2. Sudden acceleration problem occurred about 2 times a year at random. 3. Nothing have done to my car because repair shop can not find any problem, and every time the problem occur, I just put the gear in "n" and the engine will back to normal. The problem appeared mostly when the gear is in "d", and happened once in "r". Did not keep record on incident date, date should below is estimate.
My car is a used 1992 lexus sc400 and I bought it from a private owner and I didn't have the car for a week and the car caught on fire.
