FAQs—Hyundai Santa Fe XL
I was driving my Hyundai Santa Fe XL around at about 25mph when it suddenly died. No warning, no whatever. Luckily there wasn't much traffic in the area, so I was able to get it off the road. It started again after about 30 minutes. And every now and then after that day, it would stall and have a difficult time starting. This is my only vehicle and I really, really need this to work fine again. Do you have any advice on how to fix this?
This might be a failed crankshaft position sensor problem, which is common among Santa Fe units. You see, in most modern vehicles, there is a computerized engine management system that relies on the sensors to report data to the computer. The crankshaft position sensor, along with the camshaft position sensor, works to control ignition timing to let the computer know when to inject fuel and provide peak sequence to the engine. Because of its location in the engine bay, the sensor usually fails after being exposed to heat and oil leaks. The solution for this is to get a new crankshaft position sensor. If the cause of the damage is leaking oil, you might want to check other components that may need replacement or repair as well.
I have a Hyundai Santa Fe XL, and it was running fine until a few days ago when it started having problems. The vehicle suddenly stutters from second gear to third gear—and sometimes, it even slips between the two gears. The computer is not showing any codes, so I have no idea why the transmission is acting so weird. Any idea what's causing the poor shift quality in this unit?
The Hyundai Santa Fe is a modern vehicle; so if it has an automatic transmission, then there are three likely reasons why your automatic transmission would not work smoothly: low fluid level, low internal fluid pressure, and faulty pressure regulation or control. You can improve the shift quality by replacing the automatic transmission fluid, but first, make sure that the fluid level is correct. It is also advisable to update your car's onboard computer. When the cause of your transmission trouble is because of low internal pressure, you might want to check the pump. Replace it if it's already worn.
My Hyundai Santa Fe XL has a 2.7L V6 engine, and I love its performance. It's the best SUV for its price range. However, the other day, it started showing some signs of malfunctioning. When I stopped in gear, the engine started to vibrate. It was rough in idle, I guess. Gas mileage was also down, and that's not a good thing. And even up to now, the intermittent vibration persists, and I don't know what to do. Can you give me an idea of what's the problem here?
You have a faulty EGR (exhaust gas recirculation) valve that is causing the intermittent rough or unstable idle. There are several types of EGR valves, and these vary from every vehicle, so you need to know what kind of valve is installed in your Santa Fe. You may check the service manual to get this information or check the emissions decal on the underside of the hood. You should also check the type of vacuum controls—is it a solenoid or a ported vacuum switch? This information is also available in the service manual. Knowing all these will make it easier for you to troubleshoot the EGR problem. Examine your EGR valve without uninstalling it; when you rev the engine between 1500 to 2000 rpm, the valve steam should move. If not, you may need to replace it.
