I’d like to share a note about the fate of our 2015 Xcent CNG. It has run for 125000 km and the knocking issue has returned. The local garage that the car goes in for servicing diagnoses it to be an issue with the engine head and it has to be opened up.

Taxis run on CNG for over 200000 km. Our car suffered this fate, perhaps, because we never monitored the oil and coolant quality and trusted third party opinions from “experts” at different FNGs who said that the oil was okay based on Color. Apart from this, I don’t know why this would happen. The car runs alright on petrol but there’s heavy knocking.

One more issue is that the rear suspension needs attention as the left tire has uneven wear.

It is difficult to find FNGs who take an interest in these slightly older cars. It is difficult to trust people for critical parts like the engine head. Right now I’m driving on petrol but eventually the problem will occur in petrol as well.

I have two questions-
1. Is it possible to replace the head with a company part without any lathe or machining work?
2. Will the car remain reliable after this work is done?

This message is a request to all owners especially those who use CNG to always check oil and coolant quality and replace irrespective of whether the garage suggests or not. The few hundreds the garage guys saved on oil change can lead to a costly engine rebuild.

I have Xcent Petrol 4 gear Torque Converter Automatic bought in 2015. It has run 60K km so far, and I have a great ownership experience so far.

In early August (a month back), I noticed issue of tachometer needle going to zero during driving the car a couple of times. This was accompanied by increase in idling RPM (based on engine noise) to about 2000. Both times, a stop-start resolved the issue.

I consulted my FNG and they cleaned the throttle body (removed it from car, cleaned after spraying petrol, and refitted). The issue was resolved for about 3 weeks, and has returned yesterday.

Please suggest next steps to get this resolved.

Hi Guys, Yesterday observed something strange and wanted to see if it needs immediate action.

FYI I own 2014 Xcent Petrol and odo stands at 85k.

Yesterday 4 of us came from our native and I was on wheels. Just after starting the trip(around 30-40kms), check engine light came on and it stayed even after restarting the car for couple of times. So after driving for 125kms, we stopped for bio-break and I used the time to diagnose the issue. Plugged the OBD2 and started the torque app. When I scanned for fault codes it throws "P0136" error code. I cleared the error code from app and it didn't occur after that.

But after reading about P0136 error code from google, it says Faulty O2 sensor and not diagnosing it earlier can lead to engine damage. So got scared now and wanted the opinion from experts here on tbhp.

What is the next step? I didn't get the check engine light yet but worried it is some hidden issue lurking around the corner and that can put me into huge financial stress.

Do I need to take it to SA and get it checked?
Do I need to clean or replace the sensor?
Or I leave it as it is, as long as I don't get the check engine light error in console?

Please help me figure out the next action.

The issue has been resolved by replacement of crankshaft position sensor.

Hi Guys,

Been using Yoko Earth 1 175/65 R14 since 2020 in my Xcent 2 Petrol(2014) model and I can see thread depth going below the mark. So, planning to change the tyre since monsoon is on & off. My requirement is about wet grip and plush ride. Can you guys suggest some options here?

A less known fact about the XCent is the rear seat legroom it provides. I had recently travelled in a XCent on its backseat and was very pleasantly surprised with the tremendous added legroom it had. As you can see in the image, the front seat is well perched above the normal heights. I believe even a six footer can relax on its back seat with his legs resting under the front seat, while travelling. It's simple common sense that Hyundai has used. Let's hope other car makers take a cue.

Guys, had faced an serious issue with my 2014 Xcent Petrol. Started the engine and within few meters, I can see the performance is dropped and car was struggling to pick up the pace. So stopped by roadside and did an scan with OBD scanner.

Got the below 3 error codes:
Random/Multiple Cyclinder misfire detected P0300
Cylinder 1 Misfire detected P0301
Cylinder 3 Misfire detected P0303

Since the service center was closer, drove to service center and upon inspecting, the engine is shaking violently and my heart sank looking at that. I know that something is might wrong with car and left the car with heavy heart and left for home.

Is it a common occurrence with Xcent? Did anyone here faced similar issues with Grand/Xcent siblings? Waiting for the SA to analyze and get back to me tomorrow. Will update once I get any information from him.

It is likely to be the spark plugs, or the cables for the sparkplugs. Replace the plugs first and see if the issue persists. Else, you have to replace the cable as well.
It is better to ask the SA to check for these two points before proceeding to more complex diagnostics.

I have a 152,000 km run Xcent and the plugs/cables are usually the only culprit for misfire.

Already informed him to check these items. Will wait for his update tomorrow. Thanks for the info.

I own Xcent petrol 2014 and faced same issue 6 months back.

After starting the car and driving for about 1 km car started shaking violently, drove it slowly to FNG.

Issue identified was spark plugs had to be replaced, car is working fine since then.

Got the update from SA. After replacing spark plugs, engine is behaving just fine. Thanks for the information @firstdrive & @Nissan1180

Unless people sit in Swift and other cars and come back to Xcent, they wouldn't know. Xcent is one of those rare breed of car which ticks almost all the right boxes at a VFM proposition. One of the reason why I couldn't replace the car was, apart from low running, it didn't give any major issues, nor high running costs. And finding a car like Xcent today, VFM with decent list of features is just not an easy task. It does the job as Compact Sedan perfectly fine and I'm happy I get to own this one.

Got the car back from service and now the car is performing just fine. SA said there was water in spark plugs. Any idea why it happens?

Anyways the car is back to it's old self and I have completed the PMS as well. Total cost came about 9k which I felt is ok for 10th year service. Can't believe it's been 10 years already.

Have sold our 2014 Xcent now, but every alternate year the car would face some issue or the other and more often than not the culprit usually was those darn spark plugs.

This is the first time I'm facing this issue in my 10 years of ownership and hope it stays that way. Planning to keep this car for my wife for her errands!

Ten years and 1.8 lakh kms later, I am standing down from "active" (ha ha) participation in this thread. I had no plans to move away from the Xcent, but I finally decided to take the plunge and go electric. The Xcent goes to a youngster in the family for whom this is his first car. Perhaps a future BHPian !

The car has been perfect for me. I have taken it to every state in India bar three and even a dozen kms into Myanmar. All types of terrain too. And it never let me down. Not a single issue on the road, giving me the confidence to take it anywhere as long as you didn't need a 4WD. Plenty of preventive maintenance, as the car got older, perhaps contributed to this.

I know it is unfashionable to say this, but there is simply no equivalent car today in the market. Torque Converters have almost become extinct, alas.
