No it is not a hybrid, Hyundai refer to it as a "mild hybrid" I'm still not sure what it actually contributes, It so called assists when pulling away etc to reduce fuel consumption.

Hyundai’s 1.6-litre turbocharged petrol engine is supported when moving off by a belt starter-generator powered by a small lithium-ion battery (for a total of 148bhp). This gives a small surge of torque to help the petrol unit. However, the main purpose of the mild-hybrid system is so that the Tucson’s engine can shut down on the move when coasting, or earlier when coming to a junction, to help boost efficiency. The small battery runs the power steering, for example.

Tried giving it a run for thirty miles on the motorway yesterday using manual gear change (as my Tucson is an automatic) kept it in fifth gear at between 2500 and 3000 revs, taking foot off the accelerator to force regeneration when it was safe to do so, GPF lamp is still on. Booked it in the local Hyundai dealers where I purchased the vehicle to have investigated. Tried once more today in full automatic but in sport mode which keeps the revs higher, GPF lamp is still on. I have covered over 60 miles at high revs and constant speed to try to clear this but
not successful. 2900 miles

Hi all

I am from a Hyundai dealer, and this is a well known issue. They know there is a problem and are looking at it.

I have a 12 month old one that has had the light on 4 times in those 12 months and nothing I can do while driving will initiate a regeneration.

We haven't charged a single customer of ours to do a forced regeneration, and if your dealer is saying its chargeable then contact Hyundai Customer Services and kick up a fuss and don't take no for an answer.

Same with the dealer, don't just accept that it's chargeable, challenge them. All it needs is a couple of minutes time of a technicians time to initiate it on the computer and then park it up to run until it does its thing.

That's a useful piece of info.
Can I ask which model you drive i.e. normal petrol or hybrid ?

DPF light on pain in ass to put it blunt.
Have tried driving at 1500 to 2500 revs motorway driving. I think that this not getting DPF hot enough to burn soot off. This is because of the distance from the engine on down pipe. Interesting reading that 4000 revs seems to be answer ?
I will try it and get back to you. Failing this I am manually removing DPF and cleaning but should not have to do. The DPF is a rip off to get extra cash from car buyers to justify a poor design feature.

I had mine from new for 15 months before getting rid of it, 5 times it went back to the dealership for a forced regeneration, I tried everything recommended to initiate a regeneration but nothing worked, even taking the car up the motorway every 3 weeks at the recommended constant 50mph in 3rd gear what a waste of time and money that was. worst car that I have ever had in 40 years of driving
