Hi Srinivas ji,
Our observation about Tata Cars is that
> Initial Lot Batches of there car range are not the best as has many teething issues reported in
> However, OEM is pro-active and work basis customer feedback / service center observations on regular basis and keep improvising product silently
> Harrier as a product as what launched in 2019 January got several enhancements in drive, performance with improved Braking, ORVM Design changes as what sold in 2020 in BS6 and even further silently updated in 2021 too.
> Product per se as i referred earlier - fit and finish is not best. Some kind of rattles, small niggles may still be observed - however is lot lesser
> Owner need to make expectation correct that hes not buying Toyota - hes buying Tata and may experience service center and there team more than often
Having said same
> As its a Hyundai Sourced Automatic gearbox - there are no reliability issues with transmission
> Kryotec Engine is tested and proven and is like next generation of Varicor engine which Tata was using earlier and in BS6 is even further better
Final recommendation: If you buying Tata Car - try to buy from latest lot (August - September make) as you never know that some more issues are been ironed out in new batches as what say March 2021 or April 2021 lot.
Hope should help in making a choice.
