While driving, on approach to a stop signal, at an intersection the car stopped moving. The display said engine malfunction, have inspected. The electronics and engine continued to operate, but the car would not move when gas pedal was depressed. I shut off and restarted my vehicle numerous times, with no effect on the problem, the car still would not move. The vehicle behind me had to brake unexpectedly, and I could have been hit by others in the intersection, there could have been an accident.(I put car in neutral and the driver behind me, pushed my vehicle, manually, out of the intersection) AAA towed vehicle to the dealer I purchased it from, they were unable to reproduce the problem or retrieve codes to identify problem.( AAA did something under the hood before towing and I was able to drive vehicle to nearby parking lot to be towed) No other inspection has been conducted. Over prior week I noted intermittent engine revving while driving for very brief seconds and this occurred just prior to the incident that resulted in the inability to move the vehicle.

The left and/or right side sun visor does not stay in the fully retracted position and may lower slightly due to its own weight. The problem is attributed to a broken connection point where the sun visor attaches to the vehicle. Impaired visibility, particularly in bright sunlight.

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.

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.
