Low oil indicator came on after only1,800 miles since an oil change, I added a quart of oil and then the light came on again after only 1,000 miles. Asked the service department at the dealership and they said there was an issue with the oil and the turbo system and that it would be a three day repair. I was advised in the meantime to take a couple of extra quarts of oil if I was going to doing any traveling this summer.

Adaptive cruise control on at 70mph, speeding car pulls into my lane with no gap (completely cut me off), hard brake by computer, I did not tap the brake to take it off of cruise, car that had cut me off zigs into another lane while adaptive cruise control has car at about 40 mph due to hard brake. As car in front pulls out of the lane, adaptive cruise control guns the engine to 3500-4000 rpm since there was no obstruction in front of it anymore and it wanted to go back to the 70 mph preset. During this incident the Engine Malfunction light comes on, warning to get car serviced. Upon taking it in for service they found that the thermostat needed to be replaced? This seems unlikely. Car has only 15k miles on it. I have another model Mazda and the adaptive cruise control has gunned it in a similar manner, taking the car well past 3000 rpm. Mazda needs to reprogram.

Purchased Mazda CX-30 Turbo car new March 31, 2021, in Jan 2022 low oil light came on with only 5,000 miles. Dealer noted it was 1 qt low. Just prior to reaching 10,000 miles the low oil light came on again. This car is burning oil with normal driving; primarily from rural area into town 15 min away or freeway driving. This creates an unsafe situation with parts and engine failure.

I am constantly receiving a -??Low Battery Voltage Warning-?? for reasons as simple as leaving my door or trunk open for 10 minutes. I never leave my car in accessory mode to play music or anything that might drain the battery. It happens several times a month for no reason. I have not had it die on me yet, but I don-??t know if it-??s actually a low battery or software glitch.

I have just about 8800 miles on my Mazda CX-30 Turbo after a year and 5 months. Suddenly had my low oil engine light come on. I pulled over and the oil is barely on the tip of the oil stick. My last oil change, which was also my first, was completed at 4937 miles from the Mazda dealership.

The brand new vehicle was sold to me on 2/23/21 with an open safety recall. This recall was finally addressed on 5/21/21. At no time did Mazda north American operations formally notifying me of the safety record. 1) how could this happen? 2) has this shortcoming been remedied? 3) Will I receive formal notifications of future safety recalls on a timely basis?
