Has this problem been rectified in the 2019 variants as opposed to the 2018 variants?

TIA for the response.
We have a 2018 Tiago and a software update fixed the issue. the car is running good and no problems whatsoever

Re: Tata Tiago/Tigor AMT: Driveability issues

My colleague is facing a weird issue with Tigor petrol 1.2 XZA. While on the move at around 60kmph, the engine suddenly turns off completely with only the steering, brakes, and the hazard lights working. He needs to steer the car to the side of the road and start the car again, and the car starts behaving normally.
Has anyone faced such an issue? What is the solution?

I have recently faced this issue but while driving a Ritz Vdi car owned by my FIL. The car would just die in the midst of traffic. Like somebody just powered it down. The lights, steering would be working. It would start soon afterwards.

My FIL gave it to Maruti service center in camp area here in Pune. They tried many things like replacing the fuel filter, cleaning out the nozzles, replacing two of the nozzle. I don't remember exactly but it was cleaning of the nozzles that did the trick.

Re: Tata Tiago/Tigor AMT: Driveability issues

In XZA (mine is 2017, 55k kms done), is anyone facing a power loss issue, when moving from a dead stop. Example - Traffic light? When you press the accelerator, the car just struggles for power for couple of seconds before making a move finally. On the other hand, if you simply lift off your foot from brake pedal and allow the car to crawl for 1-2 seconds and then press accelerator, the car moves forward without any issue. I want to note here that the fuel pump etc has already been replaced under warranty last year and the problem still exists. Another issue is Spark Plugs going bust frequently, like every 3-4k kms or say 5-6 months. Anyone facing such problems?

Faced the exact same issue. There is a software update for the TCU. The issue gets resolved. Get it done from the service center

Yes! And often, the car will then surge ahead, leading to panic breaking. Being aware of this behavior is the first thing I tell anyone who drives my June '18 Tiago XZA.

I think my car got the TCU update last year; and I believe, the problem started after it!

Have to go to the service station soon anyway, since the front left power window button is not working. Will get this checked again. It's Tata, I fear I'm going to be told to live with it.

That surge problem is pretty dangerous. The brakes are also not so effective at slow speeds when the surge happens. Have to stand on the brakes, literally.

There is a TCU update of post August 2019. That solved the issue. I got it done in November

My car was given this update a few months when it went for another part failure. I'll impress upon the SA to fix it; else escalate this to Tata.

Check with a different service center.

The process is, the TASS has to download the latest update onto their local laptop before they can update the car. If they are lazy to download the update then they cannot update it in your car.

Ask the SA the update date and version. If possible , be with the car and see the update being done. It is a 15 minute job. You can be sure in that case. The first time i was deceived this way.

I have been living with this problem for quite some time now and I don't think it is solved by any update. I got last update done in December. Car misfires as it struggles for power which leads to short life of spark plugs, in my opinion. There is no explanation from service center, as they are more worried about their feedback and ratings. I think it is time to write a mail to Tata again. Unfortunately, my experiences with Tiago are nothing but disappointing, I plan to put up a detailed ownership review soon, with full back up. .

Re: Tata Tiago/Tigor AMT: Driveability issues

Do any of you feel the idle RPM is set really low on the Tiago?

I drive a different motor on the JTP variant but at idle, it often feels like for a second the engine will die when the AC compressor kicks in and RPM blips for a moment before settling down.

RPM stays a bit high during cold start, for couple of minutes atleast. Then settles down gradually. Once it is settled, it feels fine to me - not too low. May be it is tuned a bit different for JTP?
I concur with you on the blip though. It is quite strong and for a second it feels like engine will die. How is your AC performance in peak summer? My car always had a poor cooling in peak summer.

The cold start bit is fine. The JTP starts at about 1500 RPM and settles down after a couple mins. My car's warmed up idle is ~750 RPM, I feel it should be a bit higher so the A/C compressor kicking in doesn't drop it too low.

The RPM dipping for a second when AC compressor engages, before the blip kicks in, always feels like the motor will stall. It actually doesn't but the shake is perceptible, though wouldn't call it 'violent'.

With two occupants, I need to run it at fan position 2 for acceptable cooling in peak summer. We don't really like it too cold in the car, so someone with a colder preference will probably find it lacking.

Re: Tata Tiago/Tigor AMT: Driveability issues

Hi all
Planning to upgrade my Mahindra quanto diesel with Tigor XMA. Are all these AMT niggles are still there in fresh lots?

I guess, this is how the car is designed and common in all AMT cars made by Tata, including Nexon.
