Two little quirks till now:

Happens only when the car is moving. Not while stationary. Not with the AC, speakers etc, tried switch off everything. It seems to emanate from behind the speedometer console, but can't say till we check it. Not sure whether to wait till 1st service to report this. Anybody else got this issue?

- 1st Gear and reverse gear or notchy and difficult to engage. Ended up grinding the reverse on a couple of occasions, needs patience sometimes. Other gears are smooth.
The grinding noise, as you have mentioned, is intermittent and in my car it starts at around 20kmph in the third gear. I suspect there is something to do with a resonating frequency of the car vibration and the dashboard mounts at that engine rpm. I have lived with it as I fear that it can deteriorate if the dash is opened up.
Regarding the gear shift, it is a common issue. I have felt that releasing the clutch fully and then repressing it to engage the gear makes it easier.

Thought it was something like a resonating noise at a specific speed. But here it completely stops when the car is stationary and starts as soon as the car moves (even less than 10kmph) and continues to annoy. After sometime it disappears and later re-appears .
Let me find if i can drilldown to the cost. I had the same thought of opening the dashboard, but i was worried of something else going wrong. This seems to be emanating from behind the speedo console. Do these units use electronic sensors or the normal Pinion driven speedometers? The noise happens just after i start rolling forward and continues even in idle/neutral.

My experience with the 2012 cx has been mixed. The issues were..
1) Bent C arm with gross misalignment after I misjudged an average sized pothole. (replaced at the cost of 950bucks)
2)Engine overheating issues. TASS took two visits and total 1 week to diagnose the problem and rectify it.
3)Refused to start at a traffic signal shortly after TASS worked on the above issue. Road side assistance guy said that the belt was scraping something and got frayed off (even showed me the pieces of rubber spread around) and the dynamo could not charge.
This time TASS repaired free of charge.
4) Sensors gone kaput once. Speedo wildly fluctuated from zero to 120 randomly while driving at normal speeds.
5) AC was erratic. repaired several times. Some electrical/ wiring issues mostly.
Other smaller issues on and off.

Finally had enough of it and traded her in for a new nano twist on december 30th. Driven 200 kms till now and absolutely no issues so far.
I would say the twist feels much better put together than the old cx. Hope I wont need to post in this thread again !

Hello Guys,

So many issues being faced my Nano owners. My Nano has done 27K kms. I am facing following issues, please provide me with your valuable inputs:

1) Engine misfires once in a while, this problem was present from the showroom itself. Got it noted to TASC couple of times, but you know the state of TASC anywhere in this country.

2) The AC blower speed reduces if it is continuously used for more than 40-50 mins. Last time I got it noted to TASC they said that the thermostat was not cutting off and told me that they did some kind of setting in thermostat to rectify the problem, it came back the very next day.

3) City mileage is only 15-16 kmpl with AC ON. On highways it gives 23+ but no more than 25, whatsoever speed I drive it.

4) No rattling noise from the car, being a Tata this problem should be present but why it is'nt can anybody tell me?

Happy driving! and thanks.

.
1) Engine misfires
- This issue developed in my car after 35K kms. This is definitely due to spark plugs and/or HT Cables. Got both replaced and it runs smooth now!

2) The AC blower speed reduces
- Possibly this is due to dusty vents. It does need cleaning every other service.

3) City mileage is only 15-16 kmpl with AC ON
- I guess the car is normal in this case. 17 with a/c in city is perfectly normal.

4) No rattling noise from the car,
- You are lucky!

Default Re: TATA nano - List of ALL issues

The AC of my Nano was behaving oddly for a month with the cooling happening only occasionally. Took it for running repairs to Focus Motors, Trivandrum. The service adviser took a quick look and remarked that it could be due to a fault fuel module. His explanation was that the fuel module is supposed to send more fuel when the AC is switched on to factor for the power loss and a fault fuel module can cause the erratic behavior. Later in the day he called me and said that it was the condenser fan which was faulty and it would take a week to get the spare from Pune.

A week later I dropped the car for fixing it since I was informed that the spares had arrived. I picked up the car later in the evening with the bill explanation that the Fuel module was replace under warranty. Since I was in a hurry I forgot to ask about the condenser fan. Later in the evening I noticed the AC behaving faulty as before.

The next day I received a call from Tata Motors QS for service feedback. Since the fault existed as before I gave the lowest score of 1/10. This resulted in frantic calls from the dealer as well as the SA . They offered to pick my car and do a recheck.

The car was taken for repairs and the replaced the condenser module as well under warranty and no issues so far.

Couple of points I noticed in this episode
1. Tata Motors is very closely monitoring customer feedback - Excellent step in bringing customer confidence.
2. Tata Motors needs to ensure that spares of all components are stocked at dealers. On a very simple thought - The cost of holding the stock for all parts of a Nano should not come over 1.5lk (or less than the ex-showroom price of new Nano )

The noise reduced and was not there intermittently. Got the 1000kms service done yesterday. Apparently the noise was due to some issues with the dashboard rattling, the service center guys said they had put some packing materials behind the speeodometer console and so far the noise hasn't come back.
They had adjusted clutch play and the gears engage smoothly now. One minor niggle is that sometimes the car does not start at the first crank, this does not happen always. Noticed this happening especially after some spirited driving and if i switch off the engine without letting it idle for about half a minute. Not sure what the relation is. Was not able to reporduce this at the service center, will revisit if the issue re-occurs.

Yesterday I went to get the combination switch changed at Lexus Motors.
The work would take only 20 minutes, but the waiting time was close to 2.5 hours. We had enough time to eat a good lunch outside

The AC filter was changed and I think the car AC is more effective than the window AC installed at our house.
All service advisors have been given Tablets and the entire checklist (job card, estimation sheet etc.) is available. The irony is that the customer is first made to sign on 3-4 pieces of paper and then the service advisor has to take those details down on his tablet. If the Tata management wanted to digitize the process, why waste so many sheets of paper and the customer's time? The service advisors are unable to concentrate on the actual job because of this duplicate paperwork.
I found an interesting poster in the workshop yesterday. They called the Manza a Luxury Taxi and were offering drivers a free lunch to get their vehicles checked. I think this is a good step because the cabbies here abuse their vehicles and then say that the car was not shoddily built. A free lunch would entice them to get their vehicles checked on time and create a bit of goodwill.
Regards,

4. The rear suspension seems to be very noisy on less than smooth roads even if the vehicle is driven at 1-2 km/hr. Something like a rattling+squeaking sound is coming from day 1 when I got this car. I am unable to place if this is coming from the suspension or from the crappy JKs.
@alphahere, I had the same issue with my Nano twist purchased in Jun -2014. At low speeds, it gave a squeaky - crushy noise. The shocks wee faulty and i had it replaced this wednesday. So advice you to check it out at the TASS.

Folks,

Pardon me if i sound cliched but i too had my share of niggles with the Nano Twist. Purchased in Jun 2014, by and large it has remained trustworthy without any major issues.

However, a couple of weeks earlier, the following issues were identified

1. A strange noise (krr-krr) like some one pouring sand on paper noise from the dashboard

2. Back Suspension noise a squishy squeaky noise.

3. A host of rattles from the dashboard which will put any baby day care center to shame.

Now the issue was my car has clocked 7800 km and was not sure whether to wait and see if more crops up or get it checked now. Finally better sense prevailed and had taken it to Concorde motors pune for repairs.

A note about Concorde:
I should say that things have changed for the better, a pleasant surprise, however, i would still advise you to stay at the center and see that your car is attended to.

The SA was good, able to check & confirm the issues mentioned except for 1 for which the dashboard needs to be opened which could lead to more misery and would ask them to do it in my presence. So this has to wait till the second service due soon.

Overall the other issues have now been resolved

Reposting from another thread:

Has anyone come across issues with rust in the running board? . My guess was that this was caused by flexing of the running board ends while lifting the car. The SA confirmed it on the previous visit, need to check with them on what can be done.

Is this a design issue?, i have never seen this in other cars, the running board metal protrudes towards the edges, this fouls with the jack when lifting the car.

Did a 800km trip in the past two days. The Nano performed brilliantly. This is my 4th highway trip on my Nano , noticed that the AC was not effective as it is used to be. Initially i thought it was the extremely hot weather but on the return trip, i was driving in at night and the issue persisted. Looks like the thermostat was cutting out too early, there was air coming out the blower but not cold. Not sure if it was the icing issue mentioned earlier in the thread, as there was no reduction in airflow.
Visiting the service center this week for the rust issue, will have to check this during the visit.

Did you try cleaning the filters ? Had the same issue with my neighbors Nano. He cleaned the ac filter and everything was back to normal.

I wanted to do this. But had a lot of trouble finding the location of the filter. After going through some threads here and searching online, got info that the filter is located under the dash on the driver's side near the clutch. But not sure if im looking at the right spot.
Anyone tried this on a Nano Twist?. The steering rod runs in between, not sure if i would be able to pull out the filter.
