I worked on hyundais, I've seen anything break.
The day they have the same warranty - I'll compare them
There are a few specifics to the markets the Niva was designed for. And even within the Communist block, car markets were very different - while customers in Czechoslovakia or Hungary could buy cars with minimum wait, customers in the USSR or Bulgaria were going through waiting lists that were several years long.
A new car was a heirloom there, counting at the same rate as an appartment, and the simple ownership of a car was the goal. From there, it could be as unreliable as hell, it didn't matter - it would just get fixed.
As a private party, you couldn't buy a truck, or a pickup truck, or anything utilitarian - they were simply not for private use. The logic was - you don't have a business, you don't do private jobs, there is NO private business at all. Hence you don't need a utility vehicle. You could buy (very) used ones at auctions, in a pitiful state, with special permission. Once bought - they were (as any other larger car btw) on a "
military list". This meant that in case of war or mobilisation - your vehicle was to be immediately taken by the military to help with the war effort. As a funny side to this - people owning such vehicles had to always have, by law, a bag of sand and a shovel in their trunk.
The Niva was designed as a vehicle not meant for private ownership. While “regular” ladas were owned by private parties (after several years of waiting lists) – anything 4×4 was meant for aministrations, the army, and fleets – and was thus maintained as fleet vehicles. Nivas eventually became available for private parties after 1990-ish when markets opened.
Note that the Niva was by no means a military grade vehicle, but it very quickly became appreciated by the top brass, and was fancier than the usal UAZ to haul a general's behind to a tank shooting range and such.
These are Niva issues that are Niva specific (from new) – to be added on top of the regular Lada issues (which are in themselves endless, and not always engineering-related):
Transfer case whines, front axle’s attachments are weak, front CV axles can simply slip out of the differential on their splines sometimes, the whole transmission is subject to high wear (constant 4×4 of the not most modern type ? ), wheel bearings can be an issue at 20000 miles, the shaft that connects the transfer case and the gearbox (yes, they are separate) whines from new, which is ok, but can hide other noises when things get bad, front suspension is weak, transmission shaft usually starts vibrating after 35000 miles, which breaks other stuff. The steering box makes for the heaviest steering on Earth, and it lasts about 50000 miles.
This is just from the top of my head – not mentioning engine (it has a timing chain which doesn’t mean it doesn't needs attention and tightening as early as 35000 miles, but it's a simple procedure, I'll give it that), and RUST.
This are the issue by design. Issues with build and assembly (which batch would you get, did you get one of the worst ones from the mid-90’s, would you get lucky to get an assembly line worker’s “congratulations” signature tricks – they do exist, and they are priceless) are not factored in.
I'll admit that the Niva is one of the cutest offroad vehicles ever made. And that it has a tremendous place in automotive history. It's just that it is to be admired from afar.
