I own a 2015 Altis Grande cvt. Today while coming back home from office, the car's switchboard suddenly made a buzzer sound and all the check lights turned on, Speedo, temp gauge and tachometer stopped working and all I could see was a red battery sign and the oil sign in the mid display. Lights and indicators stopped working as well. After I reached home, I started the car again to see if the issue was there but it was back to normal. Now, the multi display is constantly changing the average fuel consumption with every throttle and brake. Has anyone experience anything of the sort? Any help will be much appreciated. Thanks.
