POWER TRAIN, ENGINE, VEHICLE SPEED CONTROL
While I was driving on I-90, I lost control of the acceleration of my vehicle. The vehicle was towed and has been diagnosed with a failed transmission! The car would not accelerate or it would accelerate in bursts or rapidly slow down. I was able to pull over and the car failed to move at all after. My safety and others was put at risk as I lost the ability to control the speed of the vehicle on a road where the speed limit is 65mph in traffic around me. When the problem began no lights illuminated, until ~30 seconds in the yellow engine failure light illuminated and then the yellow transmission failure light illuminated. The car was brought to a dealership for inspection and they diagnosed it as a transmission failure. This is unacceptable for such a young vehicle (2021). It should be noted that the car manufacturer immediately approved the replacement the same day it was diagnosed (dealership said it usually takes 48 hours), but the part is back-ordered for months (probably because they know this is happening and trying to cover it up).

ENGINE, VEHICLE SPEED CONTROL
Car lunged forward when lightly stepping on the gas while making a turn onto a busy street. Then it later lagged in responding when I stepped on the gas. About 5 minutes later, the car dashboard lit up and said there was a transmission error. Mechanic's diagnosis found code P0756 for a shift solenoid B stuck off. The car is unsafe to drive.

ENGINE, FUEL/PROPULSION SYSTEM
Low engine oil light is on again, I had one at 4600 miles and keep happening every 5-6000 miles. I had 7!! oil changes on a car that is 2.5 years old and it is at 29000 miles. I am sitting at the dealership and they are telling me nothing is wrong and despite of the valve stem cap replacement available they are not willing to replace it. In addition I had my battery die and needed to be replaced at 23 months after purchasing a brand new car - due to a faulty system. This is getting extremely upsetting. And dealearships do not care.

ELECTRICAL SYSTEM
The car has some .kind of Electric or electronic malfunction that drains the battery and kills it without giving you a warning. I have taking it to a Mazda Dealer to be fix 4 times and they don't seem to be able to fix it.The battery was replaced.twice one by me and the second time by the dealer in an attempt to solve the problem at some point. Unfortunately just yesterday it happened again it had to towed to the Mazda dealer again for the fifth time. I really hope a solution can be found.

POWER TRAIN, ENGINE
On multiple occasions, low oil warning lamp illuminates and I have confirmed low oil level. Dealer is unable to confirm and refuses to address Mazda TSB because oil level is no longer low since I topped it up. The failure lies in the valve seal assembly. My safety and that of my passengers is affected because in the event of a low oil incident, my ability to safely drive the speed limit and/or accelerate quickly is compromised. Should a catastrophic failure occur, engine would lose all power. Date of most recent incident marked below.

The contact owns a 2021 Mazda CX-30. The contact stated that while the contact's wife was driving at an undisclosed speed, several unknown warning lights illuminated. The contact stated that the vehicle decelerated to 20 MPH. The contact's wife drove the vehicle to a safe location and parked the vehicle. The vehicle was towed to an independent mechanic, but the mechanic was unable to duplicate the failure. The contact stated that the independent mechanic reset the codes and the vehicle operated as intended; however, the failure recurred. The vehicle was taken to the dealer and the contact was informed that the battery needed to be replaced. The battery was replaced but the failure reoccurred. The vehicle was taken back to the dealer where it was diagnosed with a failed MAP sensor. The contact was informed that the MAP sensor needed to be replaced. The vehicle remained with the dealer for nineteen days and the MAP sensor was replaced. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the dealer where it was diagnosed with needing a software update.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: WARNINGS
The accident occurred on the afternoon of Tuesday, November 14, which I reported to Enterprise, City of Falls Church, on the morning of November 15. Additionally, I provided to Enterprise email links to the many reports about breaking problems about the CX30 2021, 2022, and 2023 MAZA models and the reasons for their recall for repair. Here are the details about what happened. As I was trying to put the car in reverse from a standing position, the car, instead, lurched forward at great speed headed toward the Sun Trust bank. I had to use super-human strength to the brake pedal on the car to force it into a standing position. The damage to the car is due to scrapping some bark off one of the trees that separates the Sun Trust Bank property from the CapitalOne bank property where my car was parked.

VISIBILITY/WIPER
I have noticed the windshield is distorted and from reports all over the Internet that seems to be an issue with 20-22 mazda cx-30’s and I don’t think Mazda is going to replace it. It causes me to get fatigued, and a little dizzy at times during long distance driving.

UNKNOWN OR OTHER
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.

VEHICLE SPEED CONTROL, UNKNOWN OR OTHER, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
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.

ENGINE
Low engine oil level since I bought it in September 2021. I’ve had it at the dealer three times and they’ve said there are no codes on the car but they are on my Mazda app. They want me to drive it over a hour away with low oil to prove to them that the engine oil is low. I did this, shut the car off, the light went off and when the engine oil level was checked it read one quart low.
