Tata Zest Quadrajet XT (Buzz Blue): Ownership Review

[Harish83]

Do check for MIB issue
For mud entering into engine compartment, the same has been resolved by fixing bracket near the FLH and FRH mud liners.

Yeah, thats what i was wondering when you said MIB issue.
You have been to service center multiple times and I was wondering why they didnt fit it for you.
I heard they are getting it fitted for all the cars delivered now.

Steering squeaking noice I reported in my first service and was fixed to my satisfaction.

I think people are upset about the FE more because its instantly displayed. If we were following Tank to tank, most will be happy with a 17-18 average.

After my first service, I guess my mileage has increased.
Today in city it displayed more than 17 after 35 kms in Bangalore city.
I'm not facing any issue till now with my Zest.

Mine was the first car and hence the MIB issue was there and last week after my escalations they took the car and said we did this fix.
Not sure the huge difference. TML team took my car for 2 days and they quoted tank to tank with 14.9 kmpl. I am wondering how is this possible?

My clucth Plate, Oil filter, Oil Change are all replaced.

Tank to tank 14.9 just in city is good enough IMO.

Why your oil was changed so fast? did you request to do it?
It is scheduled for the second service which come at 15k kms.

What issues you had with clutch plate?
Can we know which car you were using previously?

 

[KBhatia]

No not at all. 14.9 kmpl diesel 1.2 engine is not all good. Even aria gives 11 kmpl in city.
i drive Tata Aria. Even honda city gives 13 kmpl.

The clutch plate was changed by TML when 1st service was made saying when I complained about slow torque and smoothness in car.
Oil change was done prematurely since TML wanted to investigate any foreign particle in oil.

Please start an ownership thread. Which color is your Zest?
Surprised to see such issues as they are reported for the first time.

I would politely disagree.
First, It is not 1.2, its 1.3 multijet diesel from Fiat which comes in all maruthi, fiat, and tata cars in the same segment.

I have driven dzire diesel before and it gives around 17 avg total tank to tank, so on city, it should come around 14.
I know people who drive cars which is powered by 1.3 multijet diesel in other makers like fiat.
They are getting less than 13 in city. Also you should consider the point that its the 90ps engine inZest we are talking about and not the 75ps one in most other variants.
you yourself said, aria gives 11, City gives 13. So all of them gets less and they are from a different segment. So I believe they should not be compared.

What would you consider as a good FE for a multijet fiat engine(90ps) with a car of body weight around 1200kg inside city?

Would request you to consider the cars in the same segment and compare.
Linea,Manza, Punto Evo, Dzire(only 75 ps) all comes with same engine, check the FE there, you will not ever find 14.9 in city as bad.
I'm sure those owners will be jealous, if you say mileage of 14.9 in city

May be you have set your expectations high on Mileage from Zest as you were coming down from a higher segment which already gives less FE. But those figures you are getting is realistic and practical numbers IMO.

Today on EC Flyover, I reset ed the trip meter while my wife was driving and below is what I got when we reached the Silkboard Jn.



I think I should let my wife drive the car more often

 

[Bump_that]

30kmpl ? hmmm is that real ? How did you managed to get that ?

 

[Harish83]

30kmpl ? hmmm is that real ? How did you managed to get that ?

It should be real.
Because initially it was showing 24 around when on a level road.
Then towards the end of the flyover as its slightly inclined, minimal fuel has to be pumped and so the mileage shoot up.
On this road you don't have to touch breaks.
And what is achieved is only for just 8 kms.
Not something which we will get realistically. After driving in city for 40kms, it then came down to 17 slowly.
So its showing correct figures only IMO.

 

[jagrover]

Its buzz blue..

Which showroom you are dealing with ? Please post some pics. Why can't you post your experience in FB/Twitter so that you will get some sudden response.

May be you have set your expectations high on Mileage from Zest as you were coming down from a higher segment which already gives less FE. But those figures you are getting is realistic and practical numbers IMO.

Let me elaborate.
The company quoted FE is 22 kmpl. So, I am expecting atleast 16-17 kmpl in the city.
The reason of quoting ARIA FE is because ARIA is 2.2 DICOR engine which gives around 11 kmpl in the city which the company has quoted around 13 kmpl. Hence ours being 1.3 multijet, the expectation atleast comes to around 16-17 kmpl.
Even my friends POLO 90 PS gives 17 kmpl.
Moreover, I am quoting the figures from Instrument Cluster and not T-2-T, So I am expecting more than that. I dont believe that its matter with high Expectations but I was trying to be realistic.
You have been getting constant FE of around 17 kmpl and that was I am worried on.
I drive on EC road daily since my office is in EC and never get more than 13 kmpl.

Are you driving more cautiously to get good FE or as per your normal driving pattern?
Can you observe that?
How much KM have you covered uptil now?
Also, during idle conditions can you note the changes in the FE in instrument cluster.
For me, every 12-15 sec is reduction in 0.1 with AC on.

Harish
Can you also provide me information like
1. At what RPM do you experience turbo boost
2. Noise level in the cabin with AC on and Off. You can download some APP from play store( if you own smartphone) and check the noise level inside the cabin. the ideal range should be 41-45 DB.

 

[Harish83]

Not sure. Do every owner needs to start new thread or Can continue in the same thread?

Not necessarily, But if you have a lot of info to share and time to pen down all your issues and experiences, you can think of starting a ownership review. Else, lets continue here.

Let me elaborate.
The company quoted FE is 22 kmpl. So, I am expecting atleast 16-17 kmpl in the city.

In Bangalore traffic that expectation is a bit on the higher side with multijet engines.

Hence ours being 1.3 multijet, the expectation atleast comes to around 16-17 kmpl.
Even my friends POLO 90 PS gives 17 kmpl.
Moreover, I am quoting the figures from Instrument Cluster and not T-2-T, So I am expecting more than that. I dont believe that its matter with high Expectations but I was trying to be realistic.

Again, you are comparing a different engine and setting expectations.
Every Engine has its pros n cons. I have tried polo and the cabin noise was just like sitting in a jeep. but it was more powerful at lower rpms.
Compare a Fiat multijet and see if FE is bad. If we start comparing different engines, then it will go illogical.
A guy having Xcent diesel will get more mileage in city due to its 3 cylinder engine. Will it sound logical to say that because of that Polo engine is inferior or poor performer compared to Xcent?

I think its better to check the T-T method and anything around 16-18 on average FE for mixed highway and city drive is acceptable for a multijet.

You have been getting constant FE of around 17 kmpl and that was I am worried on.
I drive on EC road daily since my office is in EC and never get more than 13 kmpl.

No, I'm not. If you read my thread, I have reported 12 in City in the worst conditions.
17 is the figure I got yesterday after my first service for 40 kms in City including 16kms on flyover.
And as it was saturday, Traffic was not that heavy. That added to the FE.
If you drive on flyover, I would suggest you to set the trip meter once you are on it and see what it shows at the end of fly over( keep speed below 100).

If thats anything below 18, there is something wrong with the car you got and needs a checkup.

Was just wondering, how was your running in period? Did you drive on high rpms during the first 1500 kms?

Are you driving more cautiously to get good FE or as per your normal driving pattern?
Can you observe that?
How much KM have you covered uptil now?

I have covered around 4750 KMS.
No, I'm not a sedate driver. I'm bit on the aggressive side, but making sure, others are not troubled because of it.

Also, during idle conditions can you note the changes in the FE in instrument cluster.
For me, every 12-15 sec is reduction in 0.1 with AC on.

Yes, thats true.
In Idle condition, FE drops pretty fast.
But thats expected when the AC is being turned on and car is not running.
Again, this is more psychological impact as you are seeing the FE coming down on the display.
we would not mind it if it didn't show up FE on display and we would get 17-18 on t-t method.

Harish
Can you also provide me information like
1. At what RPM do you experience turbo boost
2. Noise level in the cabin with AC on and Off. You can download some APP from play store( if you own smartphone) and check the noise level inside the cabin. the ideal range should be 41-45 DB.

Turbo boost is very linear in zest IMO.
It doesn't feel like kicking in suddenly like other multijets.
In my desire, it was very evident around 2K rpm when it starts pulling the car.
In zest, its spread over RPM of 1750 -2400.
This is actually because TML was successful in minimizing the turbo lag in zest.
Thats actually a positive point and not a drawback as you feel.

I will check noise level next time. I'm sure its lower than most other cars in the segment.
you can feel the difference with bare ears.
we have app store for windowsphones

I asked you so because your car got clutch/ oil replaced pre-maturely and other issues that's reported for the first time in the entire net AFAIK.
No offense. Its upto you to decide.
Again which service centre is this ?

Good News: Tata Motors called me today and informed that they designed a new Bracket to fix Mud in the Engine Bay problem in Zest. Planned to take the car to Service Station by this Weekend.

Looooong Live Zest!!

Bracket fitted for MIB issue. Time taken 1 Hour. Tata Motors Instructed to fit without removing the Head Light and Bumper . But I asked service person to remove it and fit the bracket to avoid scratches. Have to test it while raining.
