From a humble start, the Hyundai Tucson has risen to prominence.
Unimpressive as a frumpy, underwhelming SUV that launched in 2004 before being retired in 2009 in favour of the ix35, it burst back onto the scene in 2015 as a handsome and popular rival to the Toyota RAV4. Today's fourth-generation model is offered in petrol and diesel as well as front- and all-wheel drive configruations. It has garnered largely positive reviews for its style, comfort, space, practicality and features – though the 2.0-litre petrol versions cry out for stronger performance, especially out on the open road. The base model starts from $39,100, rising to $61,100 for the most expensive version.
That’s a pretty comprehensive rebuild of the fuel system, so it’s possible that something that was removed at the time has gone back on not quite the way it was. A shuddering as you slow down suggests that the idle speed is perhaps a touch low. You should be able to adjust the ide speed fairly simply, so the first thing to try is to creep it up, say, 100rpm and see if the shudder goes away.
A mechanic will be able to do this quickly and easily. If that’s not the problem, you need to go back and double check every fitting and fastener to make sure there’s no air or fuel leak that is causing the engine to develop the staggers. Were the new injector seals treated to a dollop of rubber grease before they were installed? If not, there’s a chance that fitting them may have put a small tear in the rubber seal which is now leaking.

It sounds very much like there’s a blow-by problem with this engine. The pressure created by the combustion process is somehow getting past the pistons and into the crankcase, causing the dipstick to leave its tube and blowing oil all around the engine bay.
Blow-by is often caused by worn or broken piston rings or a damaged piston itself. But modern turbo-diesels are also prone to problems with their crankcase ventilation and emissions-control systems which can become full of gunk and not allow the crankcase to breathe properly. At which point, the same symptoms can occur.
A mechanic will be able to do some tests and determine what’s causing the pressure build-up inside the crankcase. If it’s internal wear, a rebuild may be required. But if it’s a build-up of crud inside the emissions-control systems, a manual disassembly and clean might be required. Either way, your car’s warranty might cover you for this, so the Hyundai dealer is your first port of call.

Whenever you see a bunch of problems all occurring at once, the car’s body computer becomes a prime suspect. This computer is what controls functions such as door locking, power mirrors and windows, the anti-theft measures, cruise-control, lighting, wipers, powered seats, the dashboard and much, much more. All these functions can go haywire or stop working altogether (and all at once) when the body computer says it’s had enough.
Since your car has electrically controlled steering, the body computer will have a say in that as well, which could explain the weird noises. But either way, you shouldn’t drive the vehicle any farther. Any noises or strange symptoms in a car’s steering could mean a sudden loss of control at the worst possible moment.

The big news inside the 2024 Tucson is a single curved instrument and media screen display on the top of the dash and the move to a ‘shift-by-wire’ controller on the steering column which frees up space for a floating centre console with extra storage and an upgraded wireless charging pad. That means there’s lots of breathing room up front and big ticks for manual controls for audio and heating and ventilation on a 6.6-inch display.
At a minimum all Tucsons feature a 12.3-inch multimedia screen, Android Auto and Apple CarPlay, six-speaker audio (with digital radio), keyless entry and start (plus ‘Remote Start’), a leather-trimmed steering wheel, a 4.0-inch central colour instrument display (with analogue gauges), 18-inch alloys, heated exterior mirrors and all LED exterior lights.
The Tucson's cargo capacity is 539 litres.
The Tucson is a five-seat SUV with lots of space front and back. The mid-range Elite grade features partial leather trim and heated front seats with the Premium model adding ventilated front seats and heated (outboard) rear seats. The N-Line package (available across the line-up) brings leather and suede-appointed sports seats with red contrast stitching.
The Tucson Hybrid is powered by a 1.6-litre, turbo-petrol, four-cylinder engine driving the front or all four wheels through a six-speed automatic transmission with a 37kW/264Nm synchronous electric motor attached to it, powered by a compact 1.49kWh lithium-ion battery. Combined outputs are 172kW (at 5600rpm) and 367Nm (at 1000-4100rpm).
Expect 0-100km/h in around 8.0-seconds with a top speed just over 200km/h.
You’ll need 52 litres of 91 RON unleaded to fill the Tucson’s tank which translates to a theoretical range of around 980km.
