Stuck brake in rear drums? If you have been wading through puddles and slush this could happen.
Try engaging and then disengaging handbrake. Then move the car in reverse great a bit. Any change?

Or could be rusted hand brake cable.

Actually, I have to travel around 500 meters everyday in broken roads with a lot of craters filled with water.
I tried disengaging and engaging the handbrake, moving in reverse and everything. Maybe one of the rear brake pads have broken?

I know I will sort out this problem, but what I am more worried about is the engine power loss problem. Even once the car also stalled in traffic!

@mods, sorry for back to back posts but the edit option has vanished now. Please merge this one with the previous post.

I just went out to check what's wrong with the car. I started the car and the rpm was fluctuating like it was missing, so I opened the hood to see if there is any problem I can identify. But as soon as I opened the hood, there was a sound like 'bhuk' and the engine stalled

The sound was somewhere from near the throttle body or where the injectors are. I couldn't see it properly as the hood was just halfway opened when this happened.
Will be going to the mechanic tomorrow morning. I suspect something is wrong with the air filter or throttle body. What do you guys think?

Car: Fiat Punto Evo MJD; 2 weeks old, 400 kms on the ODO
Sound: A hissing noise from the underbody towards the exhaust whenever the car is idling. This is noticeable only if I stand by the side or right behind the car and not at all noticeable from the inside. This is the first diesel car I am driving so not sure if this is normal. Experts?

I head a thud-thud sound when my grand i10 passes over small potholes at speeds of 30-40 or above. It is very smooth at lower speeds. The car has done only 1200Kms. What could be the reason?

Check cold tire air pressure. Since your car is new (1200 kms on odo), it should be a good candidate for check as dealerships have notorious reputation of over-inflating car tires kept in their stockyard.

I had the similar issue in my 2009 i10 for last 3 months. Authorized service center guys could not figured out the problem and they were suggesting me to change the suspension and all, which were costing more than 20k. Somehow, I was not convinced with their diagnosis. Finally, went to my local trusted mechanic and after test driving for 1 km, he pulled the vehicle onto ramp and identified the issues with the Lower arm on the right side. The bushes/joints of the lower arm are damaged and finally, we had changed at the both the sides, which costed 2300/-. Now, I don't hear that sound. So, please have it checked the lower arm in your case also.

Can this happen in a new car?

If I keep driving like this, since the SA said its normal, will it cause more damage?

I keep the tire pressure as 33. That's the manufacturer recommend pressure.

1200 km is way too early for lower arm bush wear and tear, unless its taken a very rough hit. Cant rule out as the cars are driven by showroom guys before delivery.

Whatever it is, pursue till you get the solution and make sure you get it done under warranty.

Update: Got the car thoroughly checked. The SA was really confused and gave up. Requested me to come the next day as I didn't want to leave the car in the service station.

Next day: While cleaning the car I don't know why I lifted the boot floor. And voila, I spotted the loosely fitted spare tire. Tightened it without a thought and took the car for a spin. There was no sound. I had a wide grin on my face. Still have it, while writing this post. Sometimes, stupid things mean a lot of trouble.

This is great. You keep scratching your head to figure out and...... LOL

Car: Civic
Sound : Typical whup whup sound while driving post 40 to 50 kmph. Sound is heard better if accelerator is let off.

Is this related to tire, wheel bearings or drive shaft ?

I noticed this sound coming after a wheel alignment and balancing job.

Thanks

My i20 (2011 model) which has been driven ~15,000 km is making this weird "tak tak" noise when in first gear. It started last week. I am not sure if this is the reason, I got the tire pressure checked at a pump, and it started. I went to another pump after this (few minutes later) and verified that the pressure is fine. What could be the reason for this. Noise is coming, somewhere from the back of the car. I am not able to identify the source. There is nothing in between the tire guards and tires. They have a free way to rotate. As soon as I upshift, the sound diminishes to nothing. Anything I should inspect to get a root cause..?

Checked if you have locked the rear seats properly, secondly if you have the seat belts behind, see if their buckle is not touching anything.

Lastly check the lock of the rear hatch, also hit the rear glass lightly from inside and see if its shaking.

Hi asingh1977,
Hope that this is not anything significant.

Do you hear the "tak tak" only once or it continues as long as you are in the first gear?

You can take a trial in 1st gear (do not shift to 2nd) and make one person sit in the rear, to locate the source.

I have noticed that the kids are very sharp to observe and locate the sources of such sounds. They are also small and flexible enough to turn front - back or lean to observe.

Do you get this sound when you shift from 2nd to 1st? Or when you take reverse?
