Trending Problems

A few problems that keep popping up. There's plenty more where that came from.

  1. Elantra Nu Engine Tick

    The 1.8L Nu engine has been ticking owners off with its constant ticks, connecting rod knocks, predispostion to engine bearing failure and problems with oil sludge. These problems all happen within Hyundai's 10-year / 100,000 mile warranty,…

    The Theta II is a gasoline direct injection (GDI) engine that is well known for a lot of things and none of them are good. Bearing failure, metal debris riding on contaminated oil, piston ring defects, siezing, knocking, crying.

  1. Hyundai is recalling 187,000 vehicles but says the "root cause" of five 2.0L Nu MPI engine fires is still undetermined.

    Just a hunch, but it might have something to do with connecting rods blasting holes in the engine block allowing oil to leak out onto hot surfaces where it smolders into a flame.…

  2. Looks like last year's recall to stop Santa Fe ABS fires didn't stop all the ABS fires.

    A total of 18 SUVs have now caught on fire after internal brake fluid leaks shorted out the ABS module. Hyundai hopes swapping out internal valve seals and lowering the system's amperage can finally put an end to this issue.…

  3. Another owner has sued Hyundai and Kia for knowingly equipping vehicles with defective Theta II engines.

    Proving once again that when it comes to engines that catch on fire, people generally aren't fans. The automakers have settled similar lawsuits and issued recalls for these clunkers, but the plaintiff suggests not all affected vehicles were included.

    About the lawsuit

    • These gasoline direct injection (GDI) engines are plagued with problems. From bearing failure, to connecting rod knocks, to oil consumption, and yes – engine infernos.
    • The plaintiff bought their car used and shortly after learned that the car needed a new short block to the tune of $7,000. The work also took 6 months because there're a backorder on parts.
    • In December Hyundai recalled 128,000 vehicles over concerns they could catch on fire. But the lawsuit wants more coverage for the 2012 Santa Fe
      2011-2013, 2016 Sonata Hybrid, and 2015-2016 Veloster.

  4. Hyundai thought it could manage EV battery fires with some software updates, but then one of the "repaired" vehicles caught on fire.

    So now the company finds itself staring down the barrel of an all-out battery replacement program for 76,000 Kona EVs worldwide (that's a $900 million dollar barrel, FWIW).

    Also included are some Ioniq EVs and Electric City buses that have also run the risk of being torched. The recall will begin in South Korea before expanding to other countries. There is no official word on a North American recall, but it's only a matter of time.…
