Hi all,

First, I just want to apologise if I've posted this in the wrong thread.

A few months ago, the SCC and FCW system on my 2021 i30 started sounding off whilst I was driving on the highway. After making sure the car was still safe to drive and assuming some dirt or gunk was affecting the sensors, I carried on.

Fast forward, took my car for a service, told them that the sensors were acting up and needed to be looked at. They came back and told me that it appeared my car had been in an accident and there was damage on the bonnet, therefore voiding warranty and I would need to pay labor costs to recalibrate the system. I asked to see the damage and I was shown a tiny little paint scrape on the bonnet which I hadn't even noticed (and I check for scrapes regularly – I love my i30🥰). So fine, not what I wanted to hear, but whatevs.

Took my car back to go ahead with it and now I've been told that the whole radar system appears to have "impact damage" and will need a new radar, costing roughly 3k for the part and $600 in labor to install and recalibrate. So basically my only two options are paying almost 4k or going through insurance, still paying the excess and losing my no-claim status.

While the money is a factor, I'm more curious as to whether anyone else has had a similar experience and what you did about it? If I had knowingly been in an accident or noticed damage, I would immediately make a claim or request a repair quote. Would it be worth pursuing a concession given the circumstances or should I just suck it up and accept it for what it is?

Hi, Note to self, take lots of photos of cars condition before giving to dealership. I once had an I20 getting a service, and upon pickup I found a door ding. I pointed it out to the techs and they tried to tell me it came in like that. I then showed them that the paint could literally be blown off, proving a very recent dent. They  were forced to admit to the damage and pay for the repaint. With photos of the area around the radar, you would never have to wonder  did they or didn't they. I think I might invest in a dash cam with parking mode. With  your situation, I think showing photos of the damage would help us decide if the issue needs to be pushed further.

Thanks for that, I've uploaded a pic of the damage in question (and definitely going to invest in a dash cam now). It just doesn't make any sense to me how my sensors started malfunctioning out of nowhere whilst I was driving due to this damage. If I had been in a collision, shouldn't the sensors have an immediate reaction (which is basically the whole selling point of these features)?

We also have a 2021 I30 and have a similar issue with the smart cruise control. Since near new, we first experienced the cruise control faulting out with two indicators lighting on the dash ('Check forward safety systems' and 'Smart Cruise Ctrl (SCC) conditions not met').  We have experienced this failure intermittently ever since on a nearly daily basis during extended travels. It faults out after a lengthy period of highway travel (more than a couple hours). It will not reset by turning the ignition off and on. It only resets after many hours but even an overnight stop has on a number of occasions not reset the condition. The fault occurs irrespective of whether the front radar (behind H emblem), or windscreen camera are clean or dirty.

We have presented the vehicle to several dealers and have been repeatedly advised to present the vehicle with the fault active. Due to the intermittent nature (and inability of service centres to immediately examine the vehicle), this has not been possible. Hyundai Australia Customer Care could provide no advice other than to have it inspected by an authorised service centre who would need to contact the Hyundai technical division for support if they were unable to diagnose the cause.

The radar was eventually diagnosed as being out of alignment due to damage as they observed a small indent on the radars front face. But on inspection, I was unable to see any evidence of this and there is no damage to the front bumper behind which sits the radar. I took a photo of the radar (attached). Interestingly, there is some sort of round 'rough surface' pattern on the radar which is only evident due to the flash I used. I couldn't see this without the flash. The 'indent' is to the lower left and side of the radar and is outside of the round rough area. Could this be part of the normal condition of these radars or has there been damage at some point either before or after sale?

The radar alignment was corrected (~AUD600) and we were advised to see if this fixed the issue. We have not been able to do this yet as it requires a significant period of travel. The service centre refused to contact the Hyundai technical division despite admitting that the radar realignment may not fix the issue.

After continuing to pursue the issue, we were told that Hyundai Australia provided the following guidance:

'Hyundai technical have advised that when this vehicle has been used for extended period of time e.g. 4 – 5  (in some cases less) and has not registered another vehicle in front of its self when using radar cruise control, the vehicle is designed to then assume that the cruise control has an error. This may then cause a warning to appear on the dash advising that that the cruise control has failed.  The cruise control can then be reset by stopping the vehicle and cycling the ignition. This is a characteristic of the vehicle.'

I have not been able to find anything about this in the vehicles user handbook or in any other information online. But we do know that 'cycling the ignition' does not reset the fault.

Given the popularity of the I30, I presume this must be an issue experienced by many?
