Common Engine Problems

  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,…

  3. Santa Fe Engine Stalls

    The Santa Fe has an engine with a nasty reputation of stalling at any speed, any time, without any warning. That means no acceleration. No power steering. No power brakes. And one change of pants.

What Hyundai Owners Say About Their Engine

Hyundai Theta II Engine Knocking, Seizing, and Sludge

This was the third engine failure for this vehicle and the last. I am not going to go through this again and will slowly drive the vehicle to an auto wrecking site and give it to them.

Elantra Nu Engine Tick

Brought [car] to dealer after noted ticking noise from engine. Had already looked up ticking noise and is related to piston slap. Hyundai agreed to pay half of price of short block, my price was $4000 out of pocket. Since new short block placed has had nothing but other issues with rough idling when stopped or in park.

    The 1st generation Veracruz (2007-2012) has been recalled a second time to fix oil sneaking past defects in a valve cover gasket and damaging the alternator.

    The oil-soaked alternator will lose voltage, leading to problems such as the battery system not properly charging or the vehicle entering "limp home" mode while driving.

    Only 83% of the vehicles originally recalled were ever repaired and of those roughly 1% of the vehicles suffered from gasket leaks about two years later. Hyundai extended the warranty for the 60,000 affected vehicles hoping that would be enough, but the National Highway Traffic Safety Administration (NHTSA) ordered them to recall the problem ... again.

    The recall (#197) is expected to begin on January 8th, 2021.

    More than 1,300 Hyundai vehicles have burst into flames, now the government wants to know why. It’s about time.

    The National Highway Traffic Safety Administration (NHTSA) was petitioned to look into these non-collision fires last June. The fires are responsible for 26 injuries in Hyundai vehicles and over 100 if you include Kia. The investigation will focus on the Theta II engine, but the NHTSA plans on looking into tail lights and other potential combustion sources as well.

    Knock, knock – there’s a major defect in the 2013 Velostar’s engine management software.

    A defect that manages to find a way to prematurely ignite the air/fuel mixture in 1.6-liter turbo engines. This puts way too much pressure on the cylinders resulting in knocking noises, stalling incidents, and engine fires. The 16,500 recalled vehicles will get the same software update given to 2014 owners, which Hyundai says improved these conditions.

    Hyundai is recalling 120,000 Tucson SUVs because their oil pans can leak, damaging the engine or starting fires.

    The automaker says there’s a problem with the sealant they used for the 2011-2013 model years. Common warning signs include oil pools on the ground, knocking engine noises, the smell of oil burning on hot engine parts, a smoldering wall of flames coming out of your engine. You know, subtle stuff like that.

    Hyundai plans on sending out recall notices by the end of March 2019.

    Hyundai is recalling nearly 100,000 engines with fuel tubes that were misaligned, improperly tightened, or otherwise damaged during installation.

    This lets gas can spray out onto hot surfaces and is the **perfect recipe for engine fires. It gets worse.

    This was supposed to be Hyundai’s opportunity to right the wrongs of their gasoline direct injection engines with massive oil flow problems. Those engines were notorious for knocking, seizing, and were eventually recalled in multiple campaigns. These were the replacements and now because of an installation snafu they’re catching on fire.…

    What are the odds that your car will set itself on fire without ever being involved in a collision?

    Much higher than you’d think, especially if you’re one of these 3 million Hyundai and Kia owners.

    The Center for Auto Safety (CAS) has put together a list of vehicles that they say should be taken off the road until a pending government investigation ends with a comprehensive recall.

    CAS says Kia and Hyundai have done nothing but provide empty statements about working directly with vehicle owners who report fires. In addition, both automakers seem to be waiting for NHTSA to conclude its investigation to determine if additional actions should be taken.

    **Hy

    ndai has announced a recall of certain 2017 Santa Fe SUVs with 3.3-liter engines. The automaker says the crankshaft assemblies may have been manufactured with irregularities in the crankshaft pins, something that can cause the engine bearings to wear down. If the SUV continues to be driven with a worn engine bearing, the engine could become damaged to the point of stalling.

    Hyundai is blaming the problem on a heat treatment coil that wasn’t in the right place during manufacturing from January 26, 2017 to February 13, 2017. This led to insufficient heat treatment on the pins.

    Federal investigators are taking a look at Hyundai’s handling of Theta II engine recalls to make sure there’s no funny business going on.

    NHTSA says it took action to "investigate both the timeliness and scope of Hyundai's Theta II engine recalls, and Hyundai's compliance with reporting requirements.

    Timely and compliant? Not if you ask this lawsuit. Or this former Hyundai engineer. To date, nearly 1.7 million Hyundai and Kia vehicles have been recalled.

    572,000 Sonata and Santa Fe Sport vehicles are being recalled because the Theta II engines can seize at any moment.

    Hyundai says machining errors occurred when the engines were built and those errors can cause the engine bearings to wear out early. Those prematurely worn bearings will cause the engine to lock up, something a dealer will need to fix by replacing the engine short block.

    Hyundai admits that two errors made during manufacturing are responsible for this problem.…

    A Santa Fe engine settlement for a lawsuit filed way back in 2014 has finally been approved by a judge.

    The class-action lawsuit was filed by lead plaintiffs Julia Reniger and Greg Battaglia who claim their SUVs kept stalling without warning, causing problems with trying to steer and stop the SUVs.

    For years, owners have been complaining that their engines can stall at any speed.

    With the 2010-2012 Hyundai Santa Fe engine stall class-action lawsuit finalized by the court, the automaker agrees to reimburse customers on a claims-made basis for out-of-pocket costs if the customer's SUV experienced a documented stall. In addition, a software update will be available for free for 10 years after the date the SUVs were sold as new.

    A Theta II engine settlement for Mendoza v. Hyundai Motor Co. Ltd., et al. has been approved by the court.

    This 2015 lawsuit accusation that Hyundai concealed defects about their Theta II engine has some teeth

    , according to a former Hyundai engineer. South Korean engineer, Kim Kwang-ho, says Hyundai knew the Theta II engines have problems that cause knocking, noise and a loss of power. Kwang-ho blew the whistle by contacting the National Highway Traffic Safety Administration (NHTSA), an act that caused Hyundai to petition a court to close the mouth of the engineer.

    My Kwang-ho worked for the automaker for 25 years and now faces accusations of leaking company secrets by Hyundai’s disciplinary committee.

    Hyundai is recalling 470k 2011-2012 Sonatas with 2.0L or 2.4L Theta II engines for knocking, stalling, and potential engine fires.

    The “gasoline direct” engines are the first batch to come from Hyundai’s new engine factory in Alabama. If they keep this up, it might be their last too.

    Hyundai says manufacturing problems could have left metallic debris around the engine crankshaft and cause problems with oil flow. The pieces of metal could interfere with the oil flow through the connecting rod bearings and damage the connecting rod.”…

    Contaminated oil is carrying metal shavings on a not-so-joyful ride through the Theta II engine leading to knocks, stalls, and eventual failures according to a recent class-action filed by a Sonata owner in California.

    [The plaintiff]_ brought [her] Sonata to a dealership and was told a piston had blown out. Mendoza asked for her car to be repaired under warranty, but the dealership refused to make the repairs. However, the dealer said the engine could be replaced for $4,500. Mendoza said no and took the Sonata to a mechanic and had the engine replaced at a cost of $3,000.

    The plaintiff says she followed Hyundai’s recommended maintenance intervals and there was no reason her engine should have seized, you know other than the whole “doomed from the start” theory.…

    For

    ears, owners of 2010-2012 Santa Fe have been saying their engines can stall at any speed. Now the issue has found its way to court.

    The lawsuit claims the dealer notification letter admits the SUVs can stall because a heavy load on the alternator can cause a drop in engine rpm. The letter says even if the engine stalls it can be restarted immediately. Furthermore, the dealer letter says a "specific set of operating conditions" must occur before the Santa Fe stalls, but the lawsuit says that is false because Hyundai owners complain the problem can happen at any time.

    The “dealer notification letter” was part of a service campaign by Hyundai which owners say did nothing to fix the actual problem.
