AMT system is not reliable

I have bought Maruti Suzuki Diesel Automatic from the first batch (Feb'2018) out of factory. I have driven 63000 km till now(25Jun2022). I have had all break pad changed in first 30000kms secondly automatic transmission fails last week leading to complete opening of gear box & transmission system. This is my fourth car & all the cars were driven more than 1,50,000 kms by me due to nature of my job but i never ever had gearbox opened or clutch work done in any of my previous car. I think there is serious design issue with AMT system. Please think before opting AMT.
