Genesis Coupe

Hi there. Thanks for contacting us today. The problem with trying to diagnose that is inconsistent like you've described is that it's incredibly difficult because, in all honesty, nothing is likely "broken". It's more than possible that a few components...

Depending on the cold air intake, you may be affecting the readings from the mass air flow sensor, which may be causing the motor to stumble when pushing for more boost as you describe. The mass air flow sensor (https://www.yourmechanic.com/services/mass-airflow-sensor-replacement)...

The a/c system loads the engine when the a/c is turned on. To maintain engine speed and power, there is an "idle-up" control circuit. That control may be malfunctioning in your case. Another possibility is a problem elsewhere in engine...

I might recommend using a bottle of fuel injector cleaner in the gas tank and some Seafoam in the oil. Those together will normally smooth out any rough idle that can be fixed with cleaners.

According to the Factory Service Manual for your vehicle, the front bumper does indeed have to be removed to gain access to the washer motor. Occasionally, manuals are mistaken as to procedure and/or "access", and thus there are sometimes acceptable...

Hi there. This can be caused by a few different things. Most of the time when it comes up all of a sudden it is due to a lack of air flow due to an intake leak, a sensor that...

Hello. P2261 (https://www.yourmechanic.com/article/p2261-obd-ii-trouble-code-turbo-super-charger-bypass-valve-mechanical-by-jamahl-walker) is the code for an issue with the vehicle's turbocharger bypass valve, also known as the wastegate. If the computer detects an issue with the wastegate circuit or signal it will activate the Check Engine Light in...

Hello. Since your car is relatively new, it should still be under warranty. It is apparent to me that there is an electrical issue that is tied into all these systems. Unfortunately, under warranty technicians only get paid three tenths...

Hey there. I would recommend letting them diagnose the problem rather than just simply telling them to replace the fuel pump. The vehicle is under warranty (https://www.yourmechanic.com/article/how-to-use-your-car-warranty-successfully-by-patrick-haas) since it is a 2016 model. For Hyundai warranty to pay the dealer...

Hello. I suggest to inspect two components for possible faults. It is possible that the accelerator pedal position sensor is improperly translating pedal position which will greatly impact the air-fuel ratio negatively which could cause a hesitation. I'd suggest getting help from a...

It sounds like you may have a throwout bearing that is hanging up. When the car is not running, nothing within the transmission is spinning, thus it is possible to put the car in gear. With the engine running, there...

The rough operation and inconsistent idle that you are describing could be due to a bad tank of gasoline, dirty fuel injectors, incorrect idle speed, exhaust restrictions, vacuum leaks, incorrectly installed or damaged spark plugs, a defective or clogged fuel...

If you smell fuel then do not try and drive the vehicle since it may have a fuel leak and may catch fire. You should have a mechanic like one from YourMechanic come to you and check the car for...

Shaking or vibration (https://www.yourmechanic.com/services/engine-is-shaking-pulsating-or-vibrating-inspection) may be caused by many different things such as faulty spark plugs, poor fuel pressure or misfires. Other things such as a faulty idle air control valve (https://www.yourmechanic.com/services/idle-control-valve-replacement) may cause the engine idle to drop below...

Hi there - there are 4 engine/transmission mounts in total for your vehicle. Engine vibration is a symptom (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-engine-mount) of broken or failed motor/transmission mounts. Depending on how many of these are damaged, the estimate you received may be perfectly...

Hello. The "blow-off-valve" or BOV, is a pressure-release valve designed to prevent over-pressurization of the engine, not the turbocharger itself. While hearing some of the sounds a turbo-charged engine (https://www.yourmechanic.com/article/how-a-modern-engine-works) makes while running through the gears is a most pleasant...

Hello there, thank you for asking about your 2010 Hyundai Genesis Coupe. The service manual calls for the oil and filter to be changed every 3000 miles. If you would like help changing your oil and filter (https://www.yourmechanic.com/services/change-oil-and-filter), have a...

Hello. This may sound strange, but were you parked under a street light when the battery died? I have experienced faulty florescent lights putting out RF signals (the signals that your remote fob use) that do not let the car...

Hello. I suspect that the one of the plastic arms connecting the shifter to the transmission has broke or come out of place. The plastic stalk is a form of shift linkage and has been known to break overtime and leave...

Hi! We will be happy to assist you. The hood light not working is likely due due to a bad bulb or a loose wire. There are a few things I recommend that a technician inspect to find as to...
