Hey, my tata harrier BS6 automatic pre-facelift has a weird issue. The gearbox upshifts very slowly on full throttle. The car reaches redline and then it gets stuck there for around 2 seconds, after this 2 second pause the car finally upshifts.

This is a major issue as there is no acceleration in this 2 second lag duration. While overtaking a vehicle today i faced this and was very scary as sudden loss of acceleration while overtaking is a safety issue.

The cars shift fast on part throttle like when you are driving normally in the city. This issue only arises when accelerator is fully pressed.

Is this common behaviour on all automatic harriers/safari or is something wrong with my vehicle??. It has only done 21k kms and this behaviour is there since the beginning.

I have completed 39k and i gave car for general service got to know that coolent and oil mixed up.

Today, I was travelling from Rajkot to Ahmedabad in my two years old Automatic Tata Nexon along with my wife and in-laws. I was driving in economy mode at 85-90kmph on the right lane of the highway. Suddenly, the acceleration was gone and in a few seconds, the speed went from 85 to 30-35. I panicked as I wasn't able to accelerate and the display screen had an alert "malfunction error, call service centre".I gave the left indicator as I thought it's better to get to the left lane then stop the vehicle. I looked in both mirrors and fortunately there was no vehicle right behind me. As I went to the left lane, mode automatically shifted to the city and then immediately to sports. Then I got the acceleration back. Me and my family are fortunate enough to be alive today. Tata sucks!! Never ever buying a tata vehicle ever again in my life.

Tata Motors seems to be preparing a fairly busy FY2027, with plans for two all-new models and four facelifts by March 2027. And from the looks of it, the bigger story is clearly around electrification.

The first major launch is expected to be the Sierra EV, likely arriving between July and September 2026. It should sit between the Curvv EV and Harrier EV in Tata’s electric SUV line-up, with expected 55kWh and 65kWh battery options, along with RWD and AWD layouts.

After that, Tata is also expected to bring the Safari EV around the festive season. This could be a very important product because it will be Tata’s first three-row electric SUV and likely its flagship EV. If it borrows the Harrier EV’s battery options, we could see 65kWh and 75kWh packs with both RWD and AWD versions.

The four facelifts could be for the Tiago and Tigor line-up, including both ICE and EV versions. These cars have been around for a while now, so updates are overdue. The EV versions could also get Tata’s newer drivetrain tech from the Punch EV facelift. What’s even more interesting is the Avinya brand. Tata’s first premium born-electric model may debut in FY2027, likely as a large SUV based on a skateboard EV platform.

Overall, this feels like Tata trying to cover everything from affordable EVs to premium electric SUVs. The big question is whether they can manage quality, software and after-sales at the same pace as the product launches.

What do you guys think? Is Tata’s EV strategy starting to look genuinely strong, or are they launching too much too quickly?

I bought my Tata Nexon EV in February 2023. I’ve also owned an MG ZS EV since 2021, which has done 1.5 lakh kms without a single major issue. That experience made me trust EVs completely.

But my Nexon has been the exact opposite.

The car has clocked around 1 lakh kms so far, and it has left me stranded on the road at least 5 times. The HV battery has already been replaced 2 times under warranty.

This latest incident has been the worst one yet. The car threw an “HV Critical Alert” and was sitting at the service center for 15 days because the replacement battery wasn’t available.

Today, I finally got a call saying the battery replacement was completed… but now apparently the AC system has failed after the repair. They’re saying the entire AC assembly needs replacement — compressor, chiller, cooling components, everything.

Estimated bill? Over ₹1 lakh.

The best part: the car is now out of warranty.

I genuinely don’t understand how replacing the HV battery suddenly leads to a complete AC system failure. Currently fighting this out with Tata Motors while the car continues to sit at the workshop.

At this point, I honestly regret buying this car.

I bought Tata Tiago 2025 top model petrol in feb 2025.

Drove 16000 kms+ Long drive, short drive daily commute.

All 3 services timely done. Oil changed

Tried everything, every suggestion got online/offline...

Using max gear/ very less clutch/dont race..

but...

in summer - city- 8-10kmpl,

Highway - 16-17kmpl at 80kmph and 15kmpl at 100+ kmph speed

in winter- city 10-12kmpl,

Highway- 17-18kmpl at 80kmph and 16 kmpl at 100+ kmph speed.

Any solution or suggest?? Any DIY?

Nexon 22 owner. I renewed iRA once and probably used it couple of times either to lock/unlock vehicle remotely or to track the car during Tata service home pickup option. But I liked the assurance that if someone force open the vehicle it sent alert and had the option of engine immobilizer.

So confused between paying 2.5k per year for peace of mind, and frugal me trying to save the most and skipping it. Not able to decide.

I am from Morbi, Jai Ganesh morbi Showroom, Tata Nexon Creative S+ Diesel Manual Color Pure Grey Booking is being taken on 25/03/2026 and has not been delivered yet.

So I bought Punch last month and it's been a great experience so far. Drove first 1000 kms on petrol. 1000-1500 km on petrol-cng 50:50. Service done at 1300 kms odo.

The car returns me a mileage of 13-14 inside city (Ahmedabad) and I'm not driving in the most crowded parts of the city. Commuting to the office (13 kms) and so far I'm getting 15 kmpl on petrol while CNG is at 14 max.

I thought it was an engine issue (Tata things) but when I drove the car on highway it returned ~ 33 kms per kg. I drove it 270 kms on 7.25 kgs.

Contacted the service center they said you should try refilling in the morning (I generally refill at midnight) and they cannot do anything about it in general.

On YouTube, even Delhi folks are getting 24 kms per kg in comparable or slightly more traffic and under 5k kms on odo for pretty much every YouTuber and most are around 1-2k kms on odometer.

Perhaps that's all context. What should I do?
