THE BRAKE PEDAL GOES ALMOST TO THE FLOOR WHEN THE BRAKES ARE APPLIED. I DO NOT HAVE MUCH BRAKING AND I HAVE CHANGED THE BRAKE PADS (FRONT/REAR) AND BLED THE BRAKES AND IT DID NOT HELP. I HAVE READ THAT THE PROBLEM IS WITH THE HYDRAULIC ELECTRONIC CONTROL UNIT (HECU) AND THE PART IS COVERED UNDER RECALL FOR THE 2011 HYUNDAI GENESIS (RECALL 13V489000). SINCE IT IS THE SAME PART THAT IS USED ON THE 2011 GENESIS, DOES THE RECALL COVER THE EQUUS WHICH IS THE SAME CAR.

Manufacturer communications
A bulletin sent by a manufacturer to its dealers. Not a recall, and repairs are not necessarily free.
AIR BAGS
The National Highway Traffic Safety Administration (NHTSA) has issued an urgent safety advisory regarding dangerous, counterfeit driver‑side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN), that have been identified in U.S. vehicles following prior crashes, theft, or non‑certified airbag replacements. These inflators are not approved for use, may rupture during deployment, and have caused serious injuries and fatalities. Please see attached announcement, provided by NHTSA, for more details.
AIR BAGS
The National Highway Traffic Safety Administration (NHTSA) has identified the presence of substandard and dangerous driver’s-side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN). These inflators were not supplied, approved, or authorized by the vehicle manufacturers and have primarily been found in vehicles that previously experienced a crash and underwent airbag replacement using non-genuine parts. These dangerous inflators have ruptured during deployment, posing a serious risk of injury or death due to metal fragments entering the vehicle cabin. To date, Hyundai is aware of three people who have died while driving a Hyundai vehicle with one of these substandard replacement airbag inflators that deployed in what likely would have been a survivable crash. NHTSA has issued a public advisory urging vehicle owners and service professionals to have vehicles inspected if there is reason to believe that a non-genuine replacement airbag may have been installed. Vehicles with salvage or rebuilt titles, prior airbag deployments, or unknown repair histories may present a higher risk. NHTSA strongly cautions against self-inspection by vehicle owners and recommends inspection by trained technicians.
EXTERIOR LIGHTING
This bulletin provides information regarding condensation related to the accumulated moisture in the headlamp, rear combination lamp, daytime running lamp (DRL), or fog lamp. This TSB illustrates the various causes of condensation inside the lamp assembly. Lamp assembly replacement is NOT necessary in most cases. This condition can be eliminated by turning on the lamps with the engine running for several minutes or during normal driving operation.
POWER TRAIN
This TSB provides a procedure to diagnose and replace, if necessary, an automatic transmission with Incorrect Ratio DTC (transmission clutch slip in gear above limit) listed on Page 2.
VISIBILITY; VISIBILITY/WIPER
This bulletin contains information about the proper removal of the windshield wiper blade protective cover on all models. If the protective cover is not removed correctly, there is a possibility of the rubber insert and rail spring becoming partially separated on the inner side of the wiper blade, which could lead to poor wiping performance and/or possible scratching of the windshield glass. Follow the procedure in this bulletin to properly remove the windshield wiper blade protective cover on all new wiper blades.
ENGINE AND ENGINE COOLING
This bulletin provides important checkpoint guidelines when performing engine oil and filter change services.
Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
