Notable distortion in the windshield horizontally through driver and passenger areas. Dealership has been helpful in replacing the windshield three times thus far. The most recent windshield is clearer but still with notable distortion and is considered an aftermarket windshield. Mazda is aware of the issue and was told they are giving pushback on replacements. This issue is noted numerous times on multiple Mazda forums with no solution. From conversations with the dealership, Mazda is claiming this is normal especially close to the pillars due to vehicle design. This issue causes driver fatigue and distance perception problems while driving which is considered a road safety concern. Paperwork and vehicle are available for inspection upon request.

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.

Engine
Purchased this car on Saturday August 13th from a dealer. Last weekend on the 20th the low engine level warning came on. We checked the oil and it was at the lowest dot on the dipstick. We added one quart of oil. This car isn't even due for an oil change it shouldn't be losing any oil.
