IT REALLY is important to do the services at the specified intervals, either kilometres or time, whichever comes first. Fluids do deteriorate in time and need to be replaced to maintain their effectiveness. It's not only oil and filters, either, remember its important to change coolant and brake fluid at least annually.
SEVERAL aftermarket kits can be fitted. Among the better-known brands are Cobra and Rhino, which can be fitted by specialists. You could also take it back to the dealership and ask them to fit the sensors.
THE problem with the remote central locking is not uncommon, but it seems little can be done. It's apparently related to the wiring. The Sonata is particularly prone to electrical gremlins. With the other problem, I'd take it to a suspension specialist and ask them to ensure the front-end alignment is set correctly. It may be worth fitting better-quality front dampers, something the specialist would be able to advise on.
THERE could be many reasons, from a simple wiring problem -- and Korean cars tend to suffer from them -- to the coolant temp sensor. It may be difficult to trace, but I would start with the coolant sensor.
TRACING wind noise can be tricky because it can come from several sources. The door seal is an obvious one, but that could be eliminated by applying a strip of tape over the gap between the door and the body after the door has been closed. If the noise goes away, the seal could be the problem. If not, check around the rear-view mirrors. These are often a source of complaint. As cars become better built and more refined, some noises are eliminated, which means others that you didn't notice before become more obvious.
THE Sonata uses regular unleaded, but some Hyundai mechanics suggest running PULP occasionally to aid clean running. For the flat spot, check that the spark plugs were changed at 90,000km as recommended. The Hyundai uses platinum-tipped plugs and, because the inlet manifold has to be removed to change plugs in the three rear cylinders, mechanics have been known to leave them. They should have been replaced at 90,000km. Also check the plug leads.
THE Australian Design Rule calls for a speedo to be accurate to plus or minus 10 per cent, so at 100km/h your speedo could be showing anything from 90km/h to 110km/h. If it is showing 112km/h when you're actually doing 100km/h, it doesn't comply with the standard. The problem I have with your dyno test is that you don't know the accuracy of the dyno. It is also a machine with tolerances and you need to know what they are to determine the results' accuracy. Remember the speedo is built with tolerances so is unlikely ever to be 100 per cent accurate. Many other factors affect the accuracy of the speedo reading: the rolling diameter of your tyres, wear on tyres, inflation pressure and so on. The RACV regularly checks speedos for accuracy and results show speedos of modern cars are much more accurate than those on older cars. Most speedos checked fall on the conservative side -- that is, the indicated speed is higher than the actual speed.
FIRST go out and check the accuracy of the odometer. Markers on posts used to line many highways are quite accurately placed by the road authorities. Head out on a nearby highway and locate one of these markers and stop safely alongside it, noting your odometer reading. Reset your trip meter to zero, then drive off to the next marker and stop again, noting the reading on your odometer and trip meter. Preferably do this over a distance of 5-10km, and repeat it a number of times to improve the accuracy. That will give you an indication of the accuracy of your odometer.
MOST vehicles have a diff whine, it's the nature of the type of gears used in diffs, but you rarely hear it. Most car makers manage to isolate the noise so it doesn't travel through the car. They use all sorts of techniques to ensure it doesn't become a problem. The problem with the Santa Fe could lie in the diff itself, it could also lie in the suspension or body which can act as amplifiers. I would take up Hyundai's offer and have them fix the problem.
