My car has a 60/40 split adjustable-type second-row seat and the driver side of the 60/40 split-bench second row seat has been sliding forward during braking despite being seemingly locked in place. Apparently, a similar issue was the subject of a safety recall for 2020/2021 Mazda CX-9s (5221I). I have spoken with Mazda and they are not offering to replace the seat as part of the recall since my car is a 2019. While I understand their position, the issue appears to be the exact same one described in the recall of the 2020/2021 models.
I entered my vehicle one day to find what looked to be cracks in the top left hand corner of my center display infotainment screen. However, they appeared to be internal and could not be felt. After doing some research, I came across Service Alert SA-008/18 from Mazda which covered this issue on 2016-2018 CX-9s, among other mode…

I entered my vehicle one day to find what looked to be cracks in the top left hand corner of my center display infotainment screen. However, they appeared to be internal and could not be felt. After doing some research, I came across Service Alert SA-008/18 from Mazda which covered this issue on 2016-2018 CX-9s, among other models. I also found a memo dated May 6, 2020, which detailed an extension of warranty service for these internal display cracks. I took my vehicle to my Mazda dealership who inspected the vehicle and told me they would be filing a claim with Mazda for the repair of the screen since there wasn't a current recall for this issue on my vehicle. Mazda agreed to partially cover the replacement with me being responsible for a $543 copay. I have spoken to Mazda Corporate about this resolution being unacceptable. This issue is a known manufacturing defect on earlier models of the CX-9, and it is obviously still an issue on the 2019 models. I explained to them that this was in no way a fault of my own and I feel that the screen should be replaced at no charge to me, which was the procedure for those affected by this issue with 2016-2018 models. As of right now, the cracks only affect the top left corner of my screen but I have read of many instances where vehicle owners had the cracks continue to spread, which I feel is very distracting to the driver. I strongly feel that Mazda should be performing a goodwill replacement in full for this issue at no cost to me as the consumer, and I am very disappointed that so far they are unwilling to do so.

Many models across the country are leaving people like myself stuck with a major engine issue and Mazda admitting they have a problem without stepping up and supporting and paying for this high repair cost to correct the issue. Enclosed is a snip of the actual TSB Mazda sent to all their Dealers.

On the last week of May, my car started experiencing sputtering and stalling out problems. I made an appointment at Mazda dealership for june 6th.meantime my husband checked all fluids and coolant was low so we topped up. Car was being driven very limited due to safety concerns. Then While driving on the freeway my car displayed a “excessive engine temperature, engine output will be limited” immediately my car reduced speed from about 65mph to under 15 mph while having my whole family including myself and 4 children in the car. We almost got hit by several cars while trying to get over to the shoulder. Once pulled over to the shoulder my husband came and followed me home on the back streets. Once again checked fluids and coolant again was back low this time empty. So In a day it completely had no coolant left. When taken into Mazda dealership for the appointment, customer service was so horrible I ended up leaving and taking my car to a 3rd party service center. Was advised to have a Hydrocarbon test on cooling system that measured at zero, then advised to take it for a diagnostic due to the sputtering, stalling and coolant leak, where they ultimately determined the coolant was leaking into combustion chamber &/or intake system. Pressure test shows drop in pressure, no visible external leaks present. TSB# 01-002/23 pertaining to cylinder head assembly replacement. Now I’m waiting for my appointment at a different Mazda dealership on June 12th! Please help
