Suzuki Jimny Breakdown

Well this story hasn't turned out depressing yet but I fear its going that way. Its about my 2018 Suzuki Jimny 1.3 manual. After 2 years and 17700km it let me down just before Christmas (2019) . I'm a pensioner currently living out my time on the KZN lower South Coast. This is my last car well maybe not so anymore. So when you decide this is your last car you kinda make sure its gonna last longer than yourself hopefully if you treat her good. Morning of 10 Dec 2019 in the garage fire it up it backfires then it wont start. Sounds like the starter motors just spinning without engaging the ring gear. Luckily the AA breakdown facility caries it on the back of the truck to the dealer in Port Shepstone. Next day assuming its going to be an easy job plus its well inside the 5 year warranty therefore my travel plans for Christmas/New Year should be okay and its not going to dig into my savings. Mechanic says you might have some bent valves sir as we are sensing little compression. Hence the "spinning" sound trying to start at home in the garage I think. He says also looks like the exhaust cam shaft timings marks are not lining up properly so maybe the chain has jumped teeth. We're going to open her up. They wip the head off and its not pretty. Carbon everywhere but the valves are not bent but they wont seat as the stems are carboned up in the guides or the seats are separated by carbon. The mechanics dig deeper and find a long vertical score mark about 0,5 mm deep on the number 2 cylinder wall. After removing the pistons the number 2 shows signs of damage on the wall where the score mark is. The dealer technical team decides to seek approval from Suzuki Auto South Africa to fit a new engine. A second option is to replace just the block and pistons and repair the head. So its mid December 2 weeks before everything shuts down so I figure with a bit of luck it might get fixed however Suzuki SA are on holiday already and wont be back till 2nd week of New Year. I change my travel plans. Come New Year the dealer begins the approval process with Suzuki Auto SA in Joburg. I think at the most this should take about a week before approval and maybe another week to get the parts to Port Shepstone. However the dealer gets the run around for about a week trying to get their ducks in a row then it seems Suzuki SA decide they will send two experts down from Joburg for the day and will then make a decision within 48 hours. Cool. They come and go but then a day later another assessor arrives with a new idea. A rebore with new pistons and rings is all that is needed. Probably not the right thing to do I think. Re bores are meant to extend the life of old cars and also the engine will no longer be within standard specification plus the bores are "Wet Liners" that may need special jigging to hold them in place in the boring machine a risky option but begrudgingly I accept their decision. Then nothing happens for a few days until Suzuki SA request a fuel sample then another few days another 1 litre fuel sample they request. So theres no attempt by Suzuki SA to pinpoint the cause of the score mark and piston damage. I summise that they are trying to shift the blame away from themselves and maybe away from honoring the warranty. What am I to do in the unlikelihood that the fuel is contaminated what am I or any motorists supposed to do. Carry a device in the car that does a quick analysis at the fuel station before filling up? Approval process ongoing and this is my only car.Not good Suzuki Auto SA. Expert help now needed?
