Team-BHP - Creaking sound from the brakes & accelerator in my MG Hector

Hi,

I own an MG Hector petrol hybrid with roughly 6,900 km on the odo, purchased in November 2020.

Whenever the brake or accelerator is pressed, a creaking sound is heard, especially when the car nosedives (during braking) or the nose rises (during acceleration). It doesn't come at standstill, or while going over undulations, or while steering.

It has gone to the service centre 3 times for rectification, but the sound is still present. They say that they have tried everything from cleaning the brakes, to replacing the shock absorbers, retorquing the subframe mounts and greasing the necessary parts. Even the company people are in loop.

I have already faced a couple of problems since purchase, like within the first week, an LED DRL had to be replaced as it was faulty, a rattling noise from the rear had to be fixed, the handbrake cable of the left rear left wheel became loose and was hanging and had to be tightened. On the second day after purchase, it was discovered that the rear exhaust was rusted. This was reported and the service centre sprayed something to make it disappear. Since then, the car has been driven about 6,900 km and till now, the rust hasn't appeared. I can't understand how rust can appear within 1 month while the car was sitting idle at the dealership stockyard, and not appear after being driven for so many kilometres.

The plastics are really very creaky. They have been creaking on their own randomly (the dashboard, gear console, driver handle, sunroof, reading light control panel, etc.) since the very first month.

I don't think that these problems are desired / expected in a new car. I haven't discovered heard of these problems / issues from other MG Hector owners. Please advise as to what should I do as I have had to face so many problems in the vehicle continuously.

Now, I have completely lost trust in the vehicle as well as the brand and want a refund as problems are repeatedly coming up in my vehicle.

This seems to be a case of faulty front struts or strut mounting points. Ask the service centre to replace both struts, and check for cracks or corrosion at the upper mounting points. Fix this and check for noise again.

Sir , I am grateful for your reply .
Just wanted to tell that they say that even after replacing the shockers the sound persists , if it were polyurethane bushings then the sound would have come on standstill while pressing the gas or brake . 🙏

As mentioned mentioned by SS-Traveller, since you have checked all other possibilities, it must a be crack in the chassis/mounting point, get it checked at the earliest possible. Better take it to some FNG or water-wash center with lift and checkout the underbody thoroughly by yourself before going to authorized service center, because the service guys might not easily budge on this point if the this is the real cause, if they find it they might secretly repair but wont acknowledge it.

I also think the same as they are trying to say that it is minor , and after brake cleaning the sound will go , which they have already done 2 times.
I will go the service centre myself and get the car inspected in front of me , as I have had doubts that have been reported to the company too(from the beginning )that the car might be accidental/suffering from manufacturing defects.

From my knowledge these sounds arent supposed to come before the 1,00,000km mark , whatever part may involved.

By chassis mounting point, do you mean where the engine is mounted on the chassis (apologies for my noob questions )
How severe is this issue ? What would happen if the car suffering from this hits pothole at high speeds ? I believe there was a thread about broken engine mount on a Kia Sonet. Are these same issues ? Mods please remove this if it is off topic.

That's disappointing to hear from a newer brand, but you can contact MG over social media and highlight the issue with a clear video or something, you will get a prompt response from their team. MG got only nearly 60K customers in India, resolution will be a cakewalk for them unlike other brands with 500K or 1M+ customer base.

As mentioned by other BHPians it could be suspension mounts or even engine mounts. Being lockdown imposed in many places and restricted work hours we can only expect delayed response from local service centres but expecting that your issue will be resolved at the earliest.

Found few similar niggles reported at MG support page too.

Open the rear hatch and get someone heavy enough to jounce the vehicle a few times - observe for any creaking noise, most likely some silicone lubricant spray in the right place should stop it, avoid replacing things unless really required - factory fit is often not replicated elsewhere.

Suspension noise is not uncommon in that type of rear suspension even the new Safari suffers from rear suspension noise as the road surface gets uneven.

Thank you sir for your reply already gone to the service centre 3 times for this issue within 1 month before lockdown , company people are in the loop as well.
These problems are not desired of a new vehicle , this isn't the first problem faced by me on this car , this is the 5 th problem also this is not a squealing noise but a 'creaking noise' like the hinge of an old door
The cars that I own /have owned have gone to their respective service stations 15 times in 15 years , 9 times in 9 years , this has gone 10 times within 6 months , 2-3 days for LED replacement, 5 days for this creaking noise , another 2 -3 times for servicing and other miscellaneous vists 2-3 times for other faults.

I have been facing faults from the 1st week itself.

Have given them so many chances but now the limits have been crossed .

After spending so much one doesn't desire to be harassed in such a manner.

Whats the purpose of buying a new vehicle when it has to repeatedly undergo repairs.

How severe is this issue ?

The upper end of the strut, where it fits into the body, is the area under suspicion. The sheet metal, where the strut is bolted on, may have a minor crack. A very close inspection after disassembly would be required to determine if such a crack exists.

Thank you Sir for your advise , but checked putting weight on the fenders , at the rear , sound can't be replicated.

Sound comes from the front right hand side
Only while braking, accelerating ,also noticed when the full wheel is turned to either side and the car is allowed to roll back from the slope.

Thank you sir , will definitely tell them to check that during inspection.
Is it desired of a new car as this problem is there from the first month itself.

Can it be a manufacturing defect?
