The is a sharp rattling noise from the driver area of the dashboard when driving over uneven surfaces. It sounds like some plastic part is tapping against each other. Oddly enough I don't get the rattling when I start the vehicle after being parked overnight. It needs a few kms before it starts chattering. Once it does, I lose all the satisfaction of having bought a new car.

I'm attaching a video that captures this issues. I'll be visiting the Service center soon. Been occupied to get this rectified earlier.

The weird part is that this sound comes very randomly. It can be triggered by rough roads, smooth roads, everything in between.

Just moving the conversation from the review thread to the niggles thread. Quoting myself here for the context

Mahindra sent a pick-up truck and the Thar was sent to Eram motors, Kannur.

The SA called me the next day after the inspection and told me that there was an issue with the transmission cable, and when you slot the first gear, the car was engaging into 3rd gear; which explains the power loss . And the smell & smoke were the aftermaths of extreme clutch use due to the power loss. This is something that I'm finding hard to swallow since we did not engage the clutch throughout and the distance was less than 5km. They have also told me that the smell will fade away in time.

I have driven another 700 odd km after this incident including some off-road where I needed to engage the low range gears. I have not had the issue ever since and the intensity of the burning smell has reduced to nill by now.

Upon arriving Bangalore, I was called by the Anant Cars SA for inspecting the leakage on the Hard Top. I have explained everything that happened and he had a similar response. I insisted on a checkup and he confirmed that they couldn't find any anomalies in the Thar.

As per the SA, they have only adjusted the cable. He did not replace the cable neither opened the gearbox for changing the gear.

Mahindra is being very tight lipped about the gear issue in some cars.

Did you notice any noise when changing between 2nd and 3rd or vice versa. That has been reported by some owners

No, I haven't noticed any sound or anomalies while shifting the gear. I have driven around 700km after the fix and haven't faced any issues so far.

Though the incident was disheartening, knowing the fact that Mahindra is aware of the issue and the fixes are identified does give some amount of comfort. Thank you, slicvic. This the first, and useful info I have received on the Thar's gear issue. Please keep posting if your Birdie chirps anymore

Back to the ASC No. 4 in 5 months

There it goes again, last night around 10:15pm just when I was about to start off on the night duty I experienced a loss of power and the Thar was not moving quick enough.



OBD Check Lamp Tell tales light came ON and would not go OFF. Tried shutting off the engine and starting again a few times but nothing would help. Called the Mahindra ASC and there was little help coming through in troubleshooting what could be the issue but they did promptly give the Mahindra Helpline no to login a complaint and request RSA. Allianz RSA services came and picked my vehicle at around 12:45am and delivered it to Sireesh Auto ASC at Magadi Road. According to Owners manual 10.14.2



this could be related to Fuel/Emission related systems. 3+ hours that ASC has had their hands on the vehicle they are yet to arrive at what caused the issue. Service Manager says they are troubleshooting the wiring harness and says it could be related to Turbo also. I am wondering how many days it will take this time around.

Any updates from the ASC yet?

[Satskum]

Just got back from Sireesh Auto ASC on Magadi Road, they have opened up the Thar and it is disheartening to see it in this state for a 5 months old vehicle.




Service people are still beating around the bush and flying kites for reasons on what has happened and how they will rectify it. As of now they are claiming they will need to replace a wiring harness. They do not have it and are claiming that a dealer in Chennai has it and they will be getting it from there. (This is again a pacifier they are trying to put in my mouth). When I insisted on the Error codes i was given P2463 Which relates to the description below

"OBD II fault code P2463 is a generic code that is defined as “Diesel Particulate Filter Restriction – Soot Accumulation”, and is set on all diesel applications when the PCM (Powertrain Control Module) detects an excessive accumulation of solid particulate matter (diesel soot) in the diesel particulate filter"



I also have a doubt if these guys really have OBD Diagnostic Codes for Thar 2020 or they are using the one from Scorpio with same engine. I am also wondering if there was some other code and they gave this code to put me off the track.

Also, till date they have not provided me the list of parts they have replaced in the previous visits to the ASC for DEF issue. I would definitely need those for record keeping purpose and also future use if more problems crop up because of these hash job repairs carried out. That wiring harness they are planning to replace goes through a lot of cramped places and I don't know well these guys will put it back. Putting a wiring harness at factory when it is just a shell is completely different from putting it with everything in place and little access room.

I am kind of lost as to what to do next and my confidence in M&M is going negative right now.

If the problem is indeed with DPF as per the fault code, then it is quite obvious service centre will have a tough time solving it unless M&M directly steps in because it is a relatively new technology in India introduced with stricter BS6 emissions. The service centre folks will keep playing around with things they know to make the error code disappear like wiring harness and other electrical objects which might not help with solving the issue permanently. Ford did the same thing to my vehicle for injector problem, instead of identifying the cause they kept fiddling something to make the engine malfunction error disappear which would come back sooner or later. That brings up some questions though

1. Is there a button for manual DPF regen in Thar?
2. Does it show current DPF accumulation status in MID?
3. If so did you get any notification or warning when it is on self-regen?

Global auto makers had issues with DPF across the globe wherever they introduced DPF for Euro 6 standards, the most famous one is Toyota DPF episode in Australia. They are currently facing class action lawsuit. It took them years to fix the problem in Hilux, Prado and Fortuner. Even though they claim to have fixed it in 2020, we won't know unless people start using their vehicles more often after corona ends. M&M and TATA are relatively new to this, especially M&M as it does not have much prior experience with DPF technology due to lack of global market. This point has always been my concern with these brands.

Sadly, there is not much you can do about it apart from escalating the issue to M&M. Also check if there are other owners facing similar issues or is it just a one off case. You better hope its not a design flaw then its a long battle to get it fixed. If it is a one off case then they should be able to pinpoint the exact cause at some point.

[Satskum]

There were no other indication on the MID except for OBD Check Lamp. My Thar has already gone under the knife twice for DEF/DPF related issues in the past and it was admitted at the MASC, took almost 2 weeks to recover. There was no other notification for Self-Regen.

Update @ 11:00AM Thurday 15th Apr 2021: Sireesh MASC claims they have ordered the wiring harness and it will reach them today and by tomorrow evening "hopefully" they will be able to sort out the issue and deliver the vehicle back to me. Looks like they are selling a pipe dream to me.

Sireesh MASC delivered "No Comments" last night around 9:00pm They say they have set right all the issues, I have not received the Bill / details on what was wrong, what was replaced or repaired, driver came dropped of the vehicle and took my signature on the delivery note.

I am yet to drive it and see if everything is good. I am planning to resume my work back in the forest later this evening and praying that everything is good and there are no hidden surprises. Wish me good luck guys!!!

[darkpython9]

Hey Satskum,
Any updates about the vehicle? I've been checking this thread everyday with anxiety.

[Satskum]

Since the return of "No Comments" on 16th from the quacks I had barely managed to clock 100 odd kms and on 22nd Apr the OBD Check Light struck again with vengeance. Sireesh MASC sent a technician to check on the issue. Customary OBD diagnostic threw up a whole long list of errors. The Technician claimed these were errors from the previous issue which were sitting pretty tight in the ECU and had not been erased. He scrubbed them clean with Pril and took the vehicle for a drive, to came back and say everything is fine now but still wants to take the vehicle back to the MASC for a thorough check and return which I declined since I already had my weekend work in the forest already planned.

Less then 30mins later a call from Mahindra CC followed asking me to send the vehicle to MASC. Declined again, I wanted to do a thorough run myself before sending it back.

Between Friday evening and this morning I drove some 400 odd Kms in the forests covering mostly game roads. Recent rains in the forest made the Thar slip, slide and dance all over the place and those stock AT tires do not help at all. OBD Check Light came on randomly and went off many times during those 400 KMS. Power is definitely not the same anymore, it struggles and I can hear the engine groaning in gear acceleration. The power drop especially in 5th and 6th is too evident to go unnoticed. It prompts to down shift to 4th at the drop of the hat. 0-100 on the highway now requires a runway and is very leisurely done. It is no more the fun vehicle it was before, it sounds and feels more like a choked up engine from the pre-CRDE era Thar.

Disappointed is an understatement and the THAR is going back to Mahindra 200% sure. I have asked Mahindra CC to take it tomorrow morning and ship it back to Nasik as the 1st Customer return of Thar 2020 and put it up in a museum there.

Lots more to come on this thread in the nearest future, hold on...

Back to ASC No.5 in 5 Months

Update 9:30AM Monday, 26th Apr 2021: Sireesh MASC picked the vehicle early this morning at 8:45am. I have not yet received the running job card details. I have listed out the issues as mentioned in the previous post.

Help required from the team here:
Any Thar 2020 MT D owners from Bangalore here? Can you please get your vehicle for a free Dyno testing? I would like to have a reference in hand when they give me their version of Dyno on my vehicle. If you can please message or contact me on 990000ISHU
It will be of great help to me in getting this sorted out

Hello Bhpians,

Hope all of you are keeping well and healthy in these crazy times. I am a novice in the 4x4 domain and have received a Diesel MT Thar in Feb 21. Since the beginning I had noticed these sudden drop in power issue and had reported it to the ASC at the time of the first 1000 kms service but it wasn't given a lot of weightage as there were no tell tales. A month back it suddenly developed loss of power and the OBD lit up but it went back to normal a couple of days later. The vehicle has already gone to the ASC once just before the lockdown but wasn't diagnosed fully yet and the obd light was also gone. Last week I took it out one day for a spin on an empty patch of land behind out society and it badly got stuck in mud and I had to struggle for good half an hour to get it out with great difficulty due to the sudden drop in power. Now it's permanently on the less power mode with the OBD light being on permanently. Honestly I am quiet concerned now after reading the experience of @satskum and other fellow Thar owners. Spoke to the ASC and they want to keep the vehicle for a couple of days post the lockdown restrictions. Hoping they get the right diagnostics and the issue is resolved quickly.

Hey, I am closely following this page, so just curious if there is any update on your OBD and loss of power issue?
Thanks

[SchrödingersCar]

Dear Thar Owners facing issues/niggles posted in this thread, are all these mostly on the Diesel only or are you hearing of similar niggles on Petrol as well?
Asking since a lot seems to be related to the DPF technology.

Guess I joined the beta testers

Today, I faced the exact issue as strawmUnkey on my 550 km drive from Hyderabad to Tirupati. The first 450 kms of the drive was super smooth. Post this, rattle started on the right side of the steering at various speeds irrespective of the surface it is driven on.

Did you find a solution for this. Too irritating to drive even with music on. My car is also from VVC. If you got solution I will just ask them to implement the same in mine.

My car is going for its 1000km visit at the service center in Tirupati on Monday. But oddly though I got the service reminder @ 801 kms. Seems to be the same issue as yours.

Otherwise the drive was pretty good. I felt the ride was only slightly more bumpy than my Innova touring sport.
