2020 Hyundai Tucson — Known Issues & Recalls

Your engine is burning oil rapidly — you're losing half a tank of oil between regular oil changes. You've noticed the oil warning light coming on when turning corners or stopping on hills, and your engine recently stalled while approaching an intersection, creating a dangerous situation. This severe oil loss suggests internal engine damage that will require professional diagnosis and likely engine repair or replacement.

Your engine shut down suddenly on the highway without warning, and the dealer found it was totaled due to a missing oil drain plug. The plug may have been improperly installed during your last oil change and gradually worked loose over 1,265 miles of driving before falling out completely during highway driving at higher speeds. The fix will likely require a complete engine replacement and investigation of the oil change service that preceded the failure.

Your engine lost power without warning while driving uphill, and the dealership confirmed this is a known issue. The engine light and oil light only came on after the failure occurred. The dealership replaced the engine, and you paid $739.66 as your portion of the repair cost. The fix involved a complete engine replacement.

Your engine is burning through oil much faster than normal—you need to add oil every 4,000 miles after an oil change. The warning light that alerts you to low oil pressure only flashes briefly during hard braking or sharp turns, then turns off, making it easy to miss that your oil level is dangerously low. Without a reliable, persistent warning, you risk engine damage like seized bearings or broken internal components. This issue may require Hyundai to investigate the engine's oil consumption and improve the warning system.

Your engine is losing oil between scheduled oil changes without visible leaks underneath the car. You've noticed the dipstick reading low shortly after dealership oil changes, and you're now adding about a half quart of oil at least once a month to keep levels adequate. A mechanic confirmed this is a known issue with 2020 Tucsons, and you're concerned about potential engine damage from running low on oil. This may require engine inspection or repair to identify internal oil consumption or seal issues.

Your engine is burning about a quart of oil every 2,500-3,000 miles, meaning you lose two full quarts between regular oil changes. This is unusual compared to other vehicle brands you've owned. The issue may require engine inspection to identify internal wear or seal problems that are allowing oil to burn off.

Your engine is burning through oil much faster than normal, causing the engine to run rough and produce smoke from the exhaust with a burnt smell. The check engine light and oil pressure warning light are coming on, indicating the engine needs attention. You'll need to have the engine diagnosed and likely serviced or repaired to address the oil burning issue.

Your 2020 Tucson Sport is consuming about 1 quart of oil every 6 months, even though you're using the recommended Mobil 5W-20 synthetic oil and following all maintenance intervals. This level of oil consumption since the car was new suggests an internal engine issue like worn piston rings, valve seals, or gaskets that may need inspection and repair.

Your engine is burning oil consistently — you need to add about a quart every 1,000 miles, or roughly 4 quarts between oil changes every 5,000-6,000 miles. This problem has been happening for about two years. A mechanic may need to inspect your engine for internal leaks, worn piston rings, or valve seal issues that could be causing the excessive oil consumption.

Your engine is consuming approximately 2 quarts of oil every 1,000 miles, which is significantly higher than normal. Hyundai has declined to replace the engine under warranty despite this excessive oil consumption. If this continues, your engine could malfunction while driving, creating a potential safety hazard.

Your engine is burning through oil at an abnormally high rate—about 2 quarts for every 1,000 miles you drive. This appears to be a known issue affecting these Tucson model years, and it has already damaged multiple catalytic converters despite warranty repairs. The underlying cause hasn't been resolved, and the oil burning has persisted for the entire year you've owned the vehicle.

Your engine suddenly shut off completely while driving at highway speeds with no warning lights, leaving you without power steering or power brakes. You had to quickly maneuver through heavy traffic to safely reach the shoulder and avoid a crash. Your vehicle has a history of sensor problems that the dealership has tried to fix before, but the issue wasn't fully resolved, suggesting a deeper electrical or fuel system problem may be causing the stalling.

Your engine suddenly lost power while driving and the car went into limp mode, making it undriveable. A warning light appeared with diagnostic code P1326, which indicates engine bearing failure. Your car had to be towed to the dealership and is currently out of service. The fix will require a complete engine replacement.

Your vehicle has experienced a recurring problem four times in four months where multiple warning lights suddenly appear on your dashboard (brake warning, forward collision alert, check engine), and your car struggles to accelerate properly. The dealership has replaced different components each time (ABS module, hydraulic brakes, engine control module, and forward collision camera), but the same type of issue keeps returning, sometimes leaving you stranded on the highway. You're concerned that Hyundai isn't properly diagnosing the root cause and that the underlying electrical or sensor issue may be affecting your brakes, transmission, and engine. A complete electrical system diagnostic and possible reprogramming of your vehicle's control modules may be needed to identify and fix the source of these repeated failures.

While driving, your engine compartment began smoking. When your son pulled over to investigate, a fire started under the hood. The fire department extinguished the fire and secured the fuel line to prevent further ignition. The engine sustained severe heat damage, and your insurance company is investigating the cause of the fire.

Your 2020 Hyundai Tucson is burning through engine oil much faster than normal, requiring top-offs every 1,000 miles. The check engine light came on, and a dealer inspection found a defective catalytic converter, but an independent mechanic diagnosed a faulty engine cylinder as the root cause. Your vehicle likely needs cylinder repair or engine replacement to stop the oil consumption issue.

Your rear suspension shocks have worn out and are no longer working properly. You'll notice your car bounces excessively when driving, and you may feel reduced control over the vehicle. Your dealer has confirmed the shocks need to be replaced. The fix will involve removing and installing new rear shock absorbers.

Your car is experiencing a misfire in cylinder 3, meaning that cylinder isn't firing properly. You've already had spark plugs replaced twice and fuel injectors cleaned, but the problem has returned, and now all four fuel injectors need to be replaced to fix it.

Your 2020 Hyundai Tucson unexpectedly shut off while you were driving, though it restarted afterward. No warning lights appeared on your dashboard before or after the shutdown. Your dealer has scheduled an appointment to investigate, but the problem hasn't been diagnosed or repaired yet. The shutdown may involve the electrical system or engine and could require diagnostic testing to identify the root cause.

Your Brake Auto Hold system is engaging on its own when you start the car and won't turn off when you press the button—you have to turn off the engine, restart it, and drive for a while before it finally disengages. This problem keeps happening. Additionally, your passenger's rear seat belt won't buckle properly, and your passenger's rear door handle cracked when opening the door. Your infotainment system has also stopped working.
