LPG System Failed on My Duster, Causing Expensive Repairs

In 2023, my Duster 1.0 LPG suddenly refused to switch to LPG mode. I called for roadside assistance, and they connected me with the nearest service center (on a Sunday, mind you). I explained the issue to the service personnel, and they advised me to bring the car in for inspection. The catch was that I was in Nigde, and the nearest service center was all the way in Aksaray. After discussing the matter further, the service representative mentioned that the LPG issue and the pesky yellow key light were not significant concerns and could be resolved at the service center. They assured me that I should come in on Monday and they'd fix it. So, I made the 100 km journey to the service center on Monday, and they confirmed the problem was with the LPG pressure sensor, a chronic issue. Here's where it gets even more frustrating – they said the part needed to be replaced under warranty, but they didn't have it in stock, and it wasn't available anywhere in Turkey. So, why did they summon me to drive 100 km to get there in the first place? Now, I'm stuck in this cycle: wait for the part, travel 100 km, return home, and repeat. While all this is happening, I'm spending money on gas, defeating the purpose of having an LPG vehicle. Just two weeks ago, we had an annual service done, and they claimed there were no air filters or LPG filters available in Turkey, causing us to pay extra for the service. The kicker? When I asked about the LPG filter during the recent service, they suddenly found one and changed it, charging us a whopping 870 liras, with 270 of that labeled as labor costs. I'm not pleased with the Aksaray service center, and I suspect Adana's service might provide more reasonable rates. So, why is Aksaray charging more? With all the back-and-forth travel, I expect compensation for the fuel I'm consuming in the meantime. Dealing with such a service runaround can be incredibly frustrating, and it's high time they sorted this mess out.
