2022 Mazda CX-30

There have been 3 different ongoing issues. The car was ordered and delivered brand new in April 2022. At 4,000 miles and again at 12,000 mile is would display low oil and require 1 quart of oil. The dealership acknowledged that it has an oil consumption issue, unresolved. I have to bring it in every time it is low prior to its required oil change time/miles. At 19,742 miles the cars battery died. They replaced it an have no reason why it died. Every time I'm driving in the mountain pass the transmission will not advance above 3rd gear. The engine will whine and I have to put it into manual and move it to 4th and or 5th gear. When I coming down the other side of the mountain, I have the same issue with it only advancing to 3rd and not proceeding to 4th or 5th. Then when I reach the bottom and on flat road the message- safety system and deactivated. This last for apx 10 minutes. The dealership has no idea why it does it.

On June 07, 2023, I was driving on the highway when I noticed a rumbling noise from the front driver-side tire (215/65R18). I got out and inspected the tires and observed nothing wrong with the tires. The next day (06/08) my wife was driving the vehicle on the highway (60 mph) and the vehicle started to shake. She pull the vehicle over and got out to check the vehicle. She observed the front driver-side tire sidewall was completely torn open. My wife never hit anything or ran over anything. The tire shop (Kost) could explain what happened to the tire. The shop person stated that it looked like a complete failure of the sidewall. The tire had approx. 9000 miles on it. In all my years of driving I never had a tire fail this bad.

I've used cruise control for decades and use it even on city streets, so I can concentrate on the road rather than my speed. The concept of adaptive cruise control is great, but the execution is very flawed on my Mazda CX30. The system fails to recognize lane separation and turn lanes where lines do not exist. The result is the Mazda CX30 adaptive cruise frequently brakes to slow the car for vehicles not in the lane it is in. At some point this is going to result in a rear end accident, because of other vehicles not allowing proper distance and my Mazda CX30 slowing for no valid reason. I shared this issue multiple times with dealership service, with Mazda via their website and with Mazda via emailed surveys. Dealership service says everything is working correctly. Mazda has not responded. If I could turn this functionality off, and have it stay off, I would do so and not report it here, but it turns back on every time the car is started. I was puzzled by this being an issue for me, on my Mazda CX30, but not for friends with other vehicles. What I learned talking to friends is that they rarely use cruise on city streets, which is the primary location for the issue. I discovered a Cheverolet Traverse, I rented, only beeped at me when it detected issues at locations where the Mazda CX30 slowed.

On December 26, 2022, after running errands for an hour or so and parking outside in parking lots, I restarted the car and pulled out of a parking lot. 3 dashboard warning lights flashed, one after the other: Engine malfunction, have vehicle inspected; Dynamic stability control malfunction, have the vehicle inspected; Safety and driver support systems partially disabled, drive safely. Vehicle was stuck in high gear and would not shift to lower gear as I pulled into the driveway (fortunately I was close to home), forcing me to have to floor the gas pedal to go up the very slight driveway incline. Dealership thought they fixed the problem, exact same thing happened on 12/28/22 (same dashboard warnings, stuck in high gear) when we were on the highway. Car was barely able to make it up the exit ramp in heavy traffic, could easily have been rear-ended. We were able to get the vehicle home by driving in Manual. It would still not downshift, even in manual, but we managed to get home (about 20 miles) in high gear with slow acceleration. Once again dealership thought they fixed the problem. Exact same thing happened (same dashboard warnings, stuck in high gear) for the third time on 1/31/23. Fortunately I was close to home and was able to pull up the driveway by flooring the gas pedal once again. Car is currently at the dealership service center again. Vehicle has 8,156 miles.

Suddenly, for no known reason, the dash displayed a warning that the seat belts and air bags are not properly operational and to get the vehicle inspected. Note there is less than 3000 miles on the vehicle. The vehicle has not been involved in any collisions and has not been damaged. I have scheduled an inspection with the dealer, and an internet search revealed this is a problem with new CX-30s.

I took delivery of a 2022 Mazda CX-30 recently, and noticed that the windshield was very distorted. Moving my head caused the image to shift in unexpected ways. The windshield was noticeably wavy and caused double vision. The dealer replaced the windshield, but the replacement is also noticeably wavy, with an almost orange peel look through the new windshield. The new windshield also distorts the active driving display as well, which was not apparent on the original. When I complained about the replacement, the dealer's service manager said that what I am experiencing is "normal", and that "all CX-30s are this way", even though he previously admitted that he had never seen it before, and that the CX-50 he was driving did not have this issue at all. I see that Mazda has a technical service bulletin for this problem for older model CX-30s. https://static.nhtsa.gov/odi/tsbs/2021/MC-10203731-0001.pdf It seems that Mazda has not fixed this issue, as it is very noticeable on my 2022 model CX-30. I can understand that glass will be refractive under extreme angles, but this is when I'm looking directly ahead. If I move my head at all, the image bends and distorts. Unfortunately, the issue does not lend itself well to photos, as it is most noticeable when you have both eyes open (two eyes see through the glass at slightly different angles and points on the glass). If I close one eye, I no longer get double vision, but I doubt that's the safest way to drive.
