Worst car I ever owned was a 1989 Suzuki Swift GT. Was my very first "brand new car", having only bought used cars up till that point. On 3rd day of ownership, the A/C compressor disintegrated, taking the belt & radiator & some other stuff with it. At around 12k miles, the flywheel let loose from the engine/transaxle and buzz sawed its way thru! Couple months after that, random electrical failures that would include the car just shutting off & refusing to restart. Fog light bulbs would last exactly 8 months, then go bad, regardless of how much or little you actually used them! CV joints & boots. Rear vent windows would randomly break free of their little plastic hinges & just swing open when making sharp turns. I replaced those plastic hinge thingies so often, it was just ridiculous! A/C compressor again. Starter failed & replaced at 28k. Alternator shortly thereafter. The dealership staff knew me by name, as I was routinely in there for warranty work at least every 8 weeks. I purchased an aftermarket warranty when the factory one expired, and used that extended warranty 7 times! Once for a transmission rebuild! After a while, I just couldnt trust that car anymore, and at 74k miles, traded it in on my new (at the time) 1994 GMC Sonoma, which I drive to this day. The GMC has been very reliable for the most part, with mainly only normal wear items needing replaced. Oh, except for the heater core being replaced twice under warranty, 1 ball joint, 1 power window motor. A/C broke again about 5k miles after factory warranty expired.
