I have been warned by other drivers at night that my tail lights were out. My clock and radio both are malfunctioning. I just took the car for the yearly inspection and there is a major oil leak from a gasket. The car only has 16,000 miles on it!

My 2020 Mazda Cx-5 was 2 days old and the battery was completely drained and had to be towed to the dealer. I picked it up and they did nothing to the battery. They told me nothing was wrong and they replaced the key fob battery. Two more days after that I parked it in my garage and pushed the button to turn it off. Apparently it did not turn off and come morning, I had significant carbon monoxide poisoning and was hospitalized for 4 nights. My car would not start again and the odd thing was that the battery was drained again and there was still gas in it. My local Mazda dealer refuses to help me and I am trying to contact Mazda's main number.

Dashboard lights have gone off then back on while driving on the highway & local roads several times. Also concerned as to what else this issue affects & not sure if daylight running lights are on or off at this time or other electrical elements. Not sure the cause of this possible short in the system in addition to a battery replacement (orig. Battery & then 2 others since 7/4/20)

Purchased brand new 2020 Mazda Cx-5 on Sept 25, 2020. On Sept. 29, 2020 with < 500mi: While traveling approximately 45 mph on county road, pressed brake pedal and the pedal did not move. Several malfunction lights flashed including "power steering malfunction", "smart city brake support malfunction". repeatedly slammed on the brake pedal and it did not move at all. Tried to swerve to avoid a vehicle but the steering was unresponsive. Impacted a vehicle at a red light. Mazda service said that there was no indication that the brake was engaged before the impact except for a "hard brake event" which based on the cdr data was probably the impact avoidance system braking the vehicle. As an engineer familiar with this type of system but not this particular system specifically, I suspected a low voltage event that knocked out the brake booster and power steering. Vehicle was returned from the repair shop today Oct 28, 2020. Headlights began to flicker, again an indication of low voltage or faulty wiring. I have taken video of the flickering, I have obtained the cdr report Mazda refused to provide although I requested to see it, and the service report indicating mass airflow & vacuum codes, both caused by low voltage event.
