SummarySome customers may experience a warning message for the approaching vehicle audible system (AVAS) right after the ignition is turned on (POWER ON) while a loud noise, such as a horn, occurs close to the vehicle. Upon inspection, DTC B1A03:2B [ISB_AMP] (AVAS device circuit malfunction) is stored in memory. This may be caused by an internal initial diagnosis in the notification and warning amplifier detecting a false malfunction under this particular situation. To eliminate this concern, the control software of the notification and warning amplifier has been modified.

SummarySome customers may complain that the rear outer handle is difficult to operate or that it gets stuck when released after being pulled once. This is caused when the rear outer handle and the rear handle bracket swell up from absorbing water and the space between them is reduced, resulting in friction and resistance when returning to the rest position after the handle has been pulled. To eliminate this concern, the rear outer handle and the rear outer handle bracket has been modified to secure space between them even if the parts absorb water.

A load can be felt while the accelerator pedal is being depressed. When the accelerator pedal is depressed further, the kick-down switch is activated and a click is felt. The driver can control the kick-down by knowing the amount of accelerator depression. An electrical signal is not transmitted by the kick-down switch turning on/off.

SummarySome customers may complain about color discrepancies (brightness differences) of the image displayed on the screen when using the 360°view monitor. As this phenomenon is not a system failure, do not make any repairs or replace any parts. Explain the cause of this occurrence to the customer as follows: The 360°view monitor is a system that provides a complete picture of the vehicle surroundings by combining the pictures captured by 4 separate cameras. These cameras are installed in the front, rear, right and left sides of the vehicle. Each camera has a color adjustment function (white balance) that operates independently from each other, which can result in color discrepancy when the combined picture is displayed on the screen. This is especially true when one of the cameras captures more green objects than the remaining cameras.

SummarySSPD6 - SPECIAL SERVICE PROGRAM - VEHICLE CONTROL MODULE (VCM) PROGRAMMING - 2024 CX-90 SSPD6 - 2024 CX-90 - Vehicle Control Module (VCM) Reprogramming: This campaign will resolve three different concerns. Unintentional warning or braking when backing up. When backing up the vehicle in a parking lot or similar area, the View Monitor Camera (VMC) may detect certain physical obstacles lower to the ground such as, the tires of an adjacent vehicle, parking lines, plants, etc. even though there are no obstacles behind the vehicle. Under this condition, the Smart Brake Support (SBS) system may determine that there is a possibility of a collision, notifying with a visual (screen display) and audible (warning sound), and the brakes possibly being applied in certain cases. Driver recognition result is not displayed (on equipped vehicles) The Driver Personalization system may not recognize the driver’s face to change the seat position settings that have been programmed. In this case the vehicle interprets the driver as a “guest” (non-personalized). The vehicle driver must be in the driver’s seat within 15 seconds of unlocking the vehicle to initiate the Driver Recognition function. Mazda Radar Cruise Control (MRCC) may reduce speed to match adjacent lane vehicle While driving on a curved road condition with the Mazda Radar Cruise Control (MRCC) activated, a vehicle in the right or left lane may be detected as a vehicle in front of the CX-90 and the MRCC will unexpectedly reduce vehicle speed to match the detected vehicle. The repair will be reprogramming the VCM with modified software via M-MDS, using MDARS. There are 28,404 vehicles in the campaign in the U.S. and U.S. Territories.
