Service bulletins for the 2012 Lexus LFA

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

L-TT-0144-13 Rev2017-08-14. Service bulletin. EQUIPMENT:ELECTRICAL; EQUIPMENT:ELECTRICAL:RADIO/TAPE DECK/CD ETC.. TT: Some customers may encounter Bluetooth connectivity concerns such as: Difficulty to pair the phone, Intermittent Bluetooth failure to connect to the vehicle when first turning on the vehicle, Various Bluetooth Audio functions are no longer functioning with the customer's phone such as ability to change the track using the steering wheel controls. These concerns can be caused by changes made on the customer's phone. Make sure to inquire with the customer if the connectivity concerns occurred after receiving an operating system update on their phone or they have restored their phone data/settings recently.
L-SB-0066-11 Rev2017-08-14. Service bulletin. EQUIPMENT:ELECTRICAL; ELECTRICAL SYSTEM. LSB: When servicing interior electrical switches and components, please note the precautions in this bulletin to avoid damaging electrical components and switches. Many lubricants, cleaners, and automotive chemicals contain silicone or other compounds that may contaminate electrical contacts, and therefore increase electrical resistance and decrease switch performance. The use of any cleaners or fluids may increase the risk of further damage to electrical components.
L-TT-0142-132017-08-01. Service bulletin. ENGINE AND ENGINE COOLING. Tech Tip: Starting with the 2010 Model Year, Lexus began a gradual transition to the use of synthetic 0w-20 viscosity engine oil. There are multiple benefits of this oil, including: Reduced friction and wear on engine surfaces, improved fuel economy, Reduction in waste oil stream (in vehicles approved for 10,000 mile oil change intervals), Reduced maintenance cost (in vehicles approved for 10,000 mile oil change intervals). Due to the improved performance and durability of 0w20 synthetic oil, Lexus has extended the oil change intervals to 10,000 miles for vehicles that require this oil. With this change, the following should be noted: Only Lexus vehicles in which 0w20 oil is mandatory have been approved for the extended oil intervals. Vehicles in which 0w20 is an option to 5w20 (or 5w30) will continue to require 5,000 mile change intervals, even if 0w20 oil is used. In the case of vehicles with 10,000 mile oil change intervals, the 5,000 mile service interval has not been eliminated. The traditional 5,000 maintenance procedures (such as tire rotation) will continue to be required, and the fluid levels (including engine oil) will need to be checked and adjusted at this time. If the vehicle operation meets the standard criteria for "Special Operating Conditions" such as: driving off road, on dirt roads, towing a trailer, making repeated short trips under 32°F, or extensive idling; the engine oil must be replaced at 5,000 mile intervals, regardless of oil specified.
