2019 Vauxhall Grandland X my problem is spark plugs 2nd set of spark plugs fitted to my 69 plate grandland x in just over 12 months and 14 thousand miles since last set fitted and now can't buy the orgional fitted plugs anywhere

Not heard of any reason why they should be changed so soon on your car , seems strange at that mileage compared to other makes where they last a lot longer

Thanks whittinghame. I got a Print out from my Garage that says. The reason for the misfire is .
Engine Misfire: All models with 1.2 turbocharged engine 03/18
Cause: unsatisfactory design of spark plugs.
Remedy: Fit Modified spark plugs.
It would appear however that ,despite my mechanics best effort in locating plugs That there are no Modified spark plug available at this time for these cars.
so im not sure what to do next it would appear to me there is clearly a fault

Is this a Vauxhall dealership ? I would find it strange they cant supply the plugs as there must be thousands of cars with that engine that would be affected if that was the case .

it is not a vauxhall dealership. However the dealership was contacted by my garage and asked for spark plugs . They could not supply them as the cant get any as no one makes them or any modified plugs for that car. IT is my understanding it only affects Grandland x from around 2019 /2021 when changes were made to these cars apparently, but don't quote me on that as i am not 100 percent sure on that fact but i am trying to find out,. it is also my understand that NGK no longer make spark plugs or modified plugs for this car.
So still at a bit of a loss. I am in contact with vauxhall and I am on to my fourth escalation up the chain of command

We have just broken down on the M40, same problem and symptoms, only 9,000 miles, 69 plate, costing £350 to get us home plus £120 for extra accommodation!! Then the repairs as our turbo is affected

That's round about the time my first set were replaced at 10,000 miles when I broke down and was removed by recovery. The next time was at 24,000 miles . Only 14,000 miles since first new set
so two new sets since new car purchase. This can't be right . And on top of that you can't buy the original or adapted spark plugs anywhere. As no one makes
them.

Scandalous , needs resolved by Vauxhall and compensation of some kind if no answer to the problem

On my fourth set of spark plugs in just a year and a half.
I need help to resolve this please

We cant resolve it for you . only Vauxhall need to sort it out
