Dear sir,
I had purchased a tata Nexon XM variant (2018) KL11BL2030 vehicle from Calicut. Am the second owner of the car. and also am purchased this car on loan. I pay every month EMI also. when I took the vehicle the running kilometer was 52000km. at 60712km I put my vehicle in the service center for major service at Malayalam motors Vazhakkala, Kochi, Ernakulam, Kerala. the service cost I paid was 8165/-rs.my car showed a first-time complaint at the kilometer 64072km. the complaint was showing a red light key symbol in my car dashboard. tata breakdown assistance team arrange to tow to Thrissur hyson motors service center. they replace the oxygen sensor at 16//12/2021. I paid the charges 2832/-rs there. At the breakdown time tata motor's breakdown assistance team arrange uber for travel. the cost I pay first. the customer care executives told me it is credited my bank with in 15 working days. I pay the number of 1635/-rs. I didn't get a refund of that amount till now. I took the car from hyson and next time also the same issue reflect on 28/12/2021 the kilometers covered 64576km. The second time also the car put on the service center at hyson Thrissur. they check everything and give back the car. the third time same issue was found on 04/01/2022 the kilometer covered 64785km. this time towing is arranged to Malayalam motors Vazhakkala. they replace coolant temperature sensor, coolant and I pay the amount 3531/-rs. I took the vehicle from there and again the fourth time the same issue again reflected the kilometer covered 65828km. I call to breakdown assistance at 4 am and the executive was very unpolite and irresponsible. and they arrange to tow at 8 am. am fed up with this data product. finally, I complained today tata complaint desk and the reference number is
[protected]. am purchased this vehicle because of the pandemic corona situation. I have a three-year kid and I cant travel in public transport during this time with my kid. and I am concerned about our health. that's why I think to buy a car. found the internet Nexon have 5* rating and all. but all are misleading the consumer. the last week I suffered from chest pain and consult a doctor result was first-degree av block. if I met such kind of any critical issue that time the car will use to travel. so that I purchased the vehicle, in my case the last 2 months any emergency I go out in the car it showing temperature warning light always. It's the fourth time I face the same issue. all documents in my hand .if its required i will mail it to tatamotors.com.so I humbled request you to please take necessary action for my complaint as soon as possible.
