Happened with my brand new City with brand new aftermarket alloys at sameish speeds as yours, repercussions were nothing at all but I did freak out too, after many years the alloys were said to be somewhat bent by Honda dealership when I was looking for root cause for cabin shake when braking, got it fixed although many members advise against it, the problem vanished and the car ran perfect for many years post that too. There were no cracks in the alloys though and the bend was removed using machine plus hammer.

Don't fret too much. Cars nowadays are made better. If at all there is significant damage to the underbody, you would see some leakage/ seepage of fluids. I guess you would have checked the car by now and if you seen no leaked oil, are satisfied that you don't have any visible damage to your wheels/ tyres, your car is able to run just as it was before this incident, you are good to go.

I have hit speed breakers at about 50 - 80 kmph about a couple of times, but no major damage occurred, the car just took off and landed about half a second later.

Unscientific speedbrakers - I have seen this term a lot on auto forum. What is a scientific speedbreaker? Is there some kind of definition or a scientific rule regarding speedbreakers? Just curious.

Speed breaker is covered in multiple sections in the Civil Engineering text books ( My dad is one and I have seen him consulting those books). The Indian Road congress has also published specifications for the length and height of the breaker as per the type of road and the speed planned.

Some more information can be found on this link as well as other similar pages.

Basically a "Scientific" Speed Breaker is supposed to "warn" you to keep your speed in check.

However, in India the first part of the name (Speed) is forgotten and everyone focuses on the second part (Breaker)...

I have gone over speed breakers in highways with speed of over 70 kms in my Amaze. She just lands with a thud.

Once while driving from Hyderabad to Mumbai, i was waiting to overtake a lorry loaded with stones, suddenly one stone fell down just in front of the car. Had no time to avoid. Stone hit the underbody and passed thru the rear. Stopped and checked thoroughly and there was no oil leak. Next day gave it for service and they confirmed everything is fine except for underbody scratchs. That is the build quality of Honda Amaze.

What do you guys recommend I should do?

Similar incident with me, was driving my BRV at 80+ on a nice tarmac road and suddenly spotted a creater, like scooped out bowl with sharp edges, on the right. I could not swerve a lot because of traffic and the median on right so the front right wheel bore the brunt. My heart sank hearing the thud. The car kept going.The car had no apparent damage but started pulling to right severely.
Next day I got the balancing and alignment done at local tire shop but car kept pulling to right. The mechanic suggested possible damage to linkage, ball joint. So got an appointment at Honda workshop. They checked all the parts, the ball joints, linkages but there was no damage,m. Spent almost half day checking the entire front right suspension and linkages. Then they did the balancing and alignment, checked tyre pressure and voila the car tracks staright now. The SA was very helpful, I only had to pay for alignment and balancing. That was such a huge relief. When I asked why the tyre shop guys could not fix it he said those guys must have used standard settings whereas honda has their own car specific settings. None the less I was very happy. So my advice is book an appointment at Honda service center and get the suspension linkages checked and alignment, balancing done. All the best.

This is common to the most of us who do long distance trips. Unfortunately ours is a country which has unmarked speed breakers almost everywhere.

I have had this happen on almost every trip on my Duster . I’ve stopped giving it any thought as with over 5 years with the car, I now know it does handle it

Only recently my car steering started wobbling at higher speeds ( duster is known for a very very sensitive /feedback-rich hydraulic power assisted steering) . I got really worried but a quick balancing and alignment got it back to its near old self.


Also like others have pointed out, check the rim/alloys for any bends as well

Was driving a Honda Amaze, the breaker was asphalt type, smallish but quite nasty and steep. Now I’m worried that it may have caused some damage. Car ran ok afterwards but im unable to sleep.

What do you guys recommend I should do?
What is the usual part that gets damaged in such a scenario? My car has done about 15k kilometres.

Oh Brother!
I can feel what exactly you are feeling now.
But before I say anything, here is my story -
I used to drive a Honda Brio then. I was coming back to my Hometown with my wife, who is an expecting mother on her 18th week, sitting at the back seat. The car was fully loaded with luggages. It was early morning we started and it was raining a bit too. I was slow in state highways - doing 55/60 ish over the odo. Suddenly I hard a 'hang' and I could see that the large part of the bonnet as the front wheel flying off the road. Then came the rear - my wife's head banged the headliners as she was not wearing seat belt (I was not sure if she should or shouldn't wear seat belt). Yes, I hit a massive unmarked speed breaker.
At the end, by God's grace, no medical complication faced for my wife and the car drove just fine for next 400km after that incident.

To conclude, Honda cars are not so fragile as it may look.

Had the same experience with my Škoda Rapid past month. Car went flying , wheels off the ground, like in the cinemas and landed with a thud rear first . No perceived issues after that and did 300 kms on it. Went for wheel alignment and had a misaligned toe which may or may not be attributed with this particular event.
Shocks are fine and was able to do a 700 km round trip without any issues.
So I think you can sleep easy, unless the planetary posteriors are completely misaligned.

Intriguing line of thought, and no, Atleast the VW’s ACC and such don’t detect speed breakers. Again, these aids are not intended to drive the car for us, they’re only intended to hold control for short periods of time to avoid accidents, that is why most of these features eventually require driver inputs, or they stop the car.

Thanks all for the reassurance. It was pulling right after the incident.


1. Took it for wheel alignment, the guys fixed it and reported no visible issue found
2. 3 days later, took it for the 3rd service at Honda, they did the general checkup. I didnt tell them anything about the incident and they find any issue

I guess thats that.

But I just dont like how these Hondas feel. The body and feel is so 'halka' that I think this car wont be able to take much beating of the Indian roads.

Plus, the Honda dealerships are painful!! A post coming soon. Thanks all.

I did this stupidity last night. Was on the way back from Chennai to Bangalore. After Atibelle they have this massive speed breakers in the NH, 5 of them in a span of 12 - 14 KMS. Unfortunately, they have laid a new one which wasn’t there the last time I used this stretch. Heavy rain, poor visibility, incorrect mental assumption as to where the first one was and doing 70 in the poor weather conditions led me to hit and fly over the first one, nasty stuff.

However, the car had no visible issue or bent rim as far as I could see, and it handled well for the next 40 odd kilometers of drive. I need to take it to the service station thought for a through checkup.

Who in the right minds lays speed breakers in a tolled NH? The surface transport ministry fails to look at basic easy to solve problems like pothole free incursion free highways, avoiding unscientific speed brakers, avoiding unscientific road merges and bridges, proper visible signages, avoiding overgrowth of bushes between median etc. These basic simple to solve issues will reduce accidents and pollution. Instead they go bigtime after car makers without looking into their own backyard first.

[speedracer05]

Could high speed jump cause any of these, apart from wheel alignment issues.

1. Damage to engine mount
2. Damage to suspension component
3. Damage to steering components or steering becoming hard.

I am observing issues like (say 30%) more engine noise/vibrations in cabin and ~30% stiffer steering compared to other Octavia TDI's.
Skoda SA has been pretty unhelpful, I am looking for an experienced mechanic to root cause these issues in Bangalore, any recommendation will be appreciated!

Indeed, I came to the same conclusion after my BRV survived the high speed crater hit incident without any damage . Eventually it was found that the front right tire had lost it's shape so the car kept pulling despite no mechanical damage, alignment and balancing. I replaced all 4 tires, almost 5 years old and the car is stable now without any pulling. Love the way it tracks straight now
