NHTSA Complaint #11600196 — 2012 LEXUS CT

A 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 many 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. 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 for a heavy amount on several different websites. The trouble code is: C1391. I called Lexus of Austin and was told there are no recalls, after looking up my VIN#. Searching for “c1391 danger” will yield many incidents of this. This is quite a serious issue that needs government interference. Thank you for taking the time to read this.
