FAQs—Hyundai Elantra Coupe
My Hyundai Elantra Coupe has been having a transmission problem for a while now. It won't shift correctly, and it seems to happen more when I'm hovering at around the speeds when I needed to shift. I was told this has something to do with the engine speed sensor. Though it doesn't happen all the time, it's getting annoying. Can you please tell me what is happening with my car?
Your vehicle's speed sensor is responsible for sending information to the car's computer about how fast your engine is spinning at any particular moment. When this malfunctions, it can wreak havoc in your vehicle's performance. Among the common symptoms of a bad sensor is a malfunctioning transmission—revs higher before it change gears, engages into overdrive late, does not shift, or shifts erratically. If you are experiencing any of these problems, you may need to take your car to the nearest shop or into your local dealership to have them run a computer diagnostic. While some transmission and engine-related problems can be solved in your own garage, drivability issues are best left for professionals since they have complete and advanced diagnostic equipment.
My Hyundai Elantra Coupe's power windows are now acting up. Sometimes the windows will work fine; in some other times, they only work using the driver-side control. There are also times when the windows will go down but will not go up. Can you please suggest a permanent fix for this problem?
If all windows stopped working at once, it is likely caused by loss of power to the system. Since many power window systems use a single relay and power supply, all of them will stop working when the relay goes bad or when a fuse is blown. Check the fuse and relay and replace a bad one. If all fuses and relays are good, the next thing to check is the driver master switch. Power often runs through this one switch and all windows will stop working when the switch failed. When only one window will not open or close, it is likely that a power window motor, door switch, or window regulator is the culprit. When you press the power window switch and there is no sound coming from the door, this means that the motor is bad and is producing very little or no power at all. When there is a sound but the window is still not working, it usually means the power window regulator has gone bad.
This Elantra Coupe has been a joy to drive until problems started to come up. Lately, its automatic transmission is starting to deliver poor shift quality. I want to check the problem myself first before paying a mechanic again. Can you advice me on what I should do?
Poor shift quality is usually attributed to low transmission fluid level. This is one of the most common transmission problems and, thankfully, also one of the easiest to fix. First, determine whether you really have low fluid level by inserting the dipstick in the reservoir. Look up your owner's manual for the recommended transmission fluid level for your car. To get an accurate reading, the fluid must be warm, so drive up a little bit to warm it up. Make sure to set your transmission to Park when doing the checking to avoid any accident. The fluid level should be between the ADD and FULL marks in the dipstick; top up if this is not the case. Make sure to use the transmission fluid that is approved by Hyundai to avoid voiding the warranty (if there is one).
