common problem with these Lexus ct200h, as well as Toyota Prius V models, are that the brake accumulators begin to leak internally, as they share the same part numbers. Therefore, the actuator will buzz every few seconds trying to keep pressure in the braking system to a safe operating level of gas pressure to no avail due to this leak in the actuator. After it quits buzzing from shutting the car off, you can hear the air leak hissing the pressure away. There are tons and tons of articles on this issue online as this is a major safety concern. Many have had Toyota replace the part free of charge as well due to the extended 10 year, or 150k miles, in whichever comes first. warranty. This may be perhaps because there are several more prius on the road than this rare Lexus CT200H. Just look up “c1391 danger” and see what comes up.

There is Not much stopping distances when and after this suddenly occurs. In the process, the abs, traction control, brake, a yellow exclamation mark, lights suddenly all come on the dash at once and the brake feels like a sponge very suddenly, as it did me as I was driving today. There were no engine lights as I started my drive. There are no external brake fluid leaks involved for this actuator. Toyota covers it under extended warranty, although it appears as though Lexus does not, this is a major safety hazard and concern. The trouble code is.: C1391. Also, I went to Sewell Lexus of Dallas today and was told there are no recalls, after looking my vin #. The service program had expired and there is nothing they can do for me. Please extend the program or issue a recall for this dangerous failure. The repair cost is substantial and should be covered for a known flaw.
