Hero Electric — Defective unit

I had purchased Hero Optima LX, on 10th march 2021 at Cuddalore showroom Tamil Nadu. Continues problems occuring,
1. mottor run at high speed
2. Charger not working properly
3. Battery got swelled up
4. Speedometer not working
5. Odometer not working
6. Throttle not working properly
7. Very poor milage 10km for 10 hours charging
Above mentioned problems are attended by mechanics of showroom but not successful, they are not that much skilled. They applied battery for warranty.
You can also verify it with your experts committee.
