Used Mitsubishi Magna review: 1999-2000
By Graham Smith · 02 Aug 2010
Despite being condemned over the years as being boring and bland the Mitsubishi Magna stands out as one that can deliver cheap, reliable motoring.  If they had their critics, they also had their fans, and those who bought Magnas, like the TH, generally became hooked on them.  The Magna is no longer on the market, but there are plenty of them still out there on the used car market, and they can make good buying.MODEL WATCHThe TH Magna was the third makeover of the third generation Magna first released in 1996.  By the time the all-new Gen 3 model was launched the Magna had acquired a reputation for being a steady and sure choice, the sort of car appreciated by people nearing their dotage. But the new Magna was an attempt to rid itself of this baggage and broaden its appeal to younger buyers.Where previous models had been chunky with generously rounded curves the new model had sweeping lines and more athletic proportions.  So sleek was its shape that it was the most aerodynamic car made in this country.It was wider and longer than the outgoing model with increased front and rear legroom and more boot space, but the sweeping roofline attracted quite a deal of criticism for its negative impact on headroom.The new Magna also featured frameless windows and slim B-pillars in an effort to create a more airy feeling inside, but it wasn't enough to quell the critics who slammed the grey trim and high waistline for making the cabin seem dull and generally depressing.When the TH update model arrived early in 1999 it boasted a more aggressive grille, revised rear, updated interiors, and new wheel covers and alloy wheels.  Gone by then was the four-cylinder engine that had been offered in previous models and Magna buyers could only buy a V6.A 140 kW 3.0-litre single overhead camshaft V6 was available in the entry level Executive model, but the rest of the range boasted a 3.5- litre V6 that had performance peaks of 147 kW and 300 Nm.Buyers could choose between a five-speed manual and a four-speed auto, with most choosing the auto. As with previous models the final drive was through the front wheels.The TH also introduced a number of innovations to the local market.  It was the first Australian-made car with ABS anti-lock brakes with Electronic Brakeforce distribution (EBD), and the first to offer Traction Control.It also had air-conditioning as standard, a trip computer and an integrated anti-theft alarm.  The model line-up kicked off with the Executive, followed by the Advance, Altera LS and Sports.IN THE SHOPThere are few reports of troubles with the TH Magna, which backs up the claims that it's pretty well bulletproof.  Most reported problems can be traced back to a lack of maintenance so   check the service history of any car on sale. This can be neglected in cars as old as the TH as they can pass into the hands of owners who are sometimes unable to afford proper servicing.Remove the dipstick and take a look at the oil, if it's black and dirty take a closer look at the service record.  You're likely to find oil leaks around the engine and these could require fixing for a roadworthy, so take them into consideration.Take note of the way the transmission shifts, particularly note any hesitation or reluctance to shift gears, and rule out any car that shows a problem in this area.  Inspect the front driveshafts for damage to the rubber boots. Walk away if any damage is found.  Not all engines in the TH range were LPG compatible, so make sure the engine in your chosen car is if you plan to convert it.IN A CRASHThe base Executive model didn't have airbags, but all other models in the TH range had dual front airbags.  All boasted ABS anti-lock braking with the new feature of Electronic Brakeforce Distribution (EBD).AT THE PUMPMitsubishi claimed the 3.0-litre V6 models with do 6.6 L/100 km on   the highway and 9.0 L/100 km around town; it also said those with the 3.5-litre V6 would do 11.0 L/100 km around town and 6.8 L/100 km on   the open road.  Road testers reported the 3.5-litre V6 would average 10-13 L/100 km.OWNER'S SAYOf all the cars Damien Hamilton and his wife have owned, and they   include an HSV3800, a Nissan 200SX, a Toyota Corolla, three Toyota Camrys and two Toyota Aurions, the 1999 TH Mitsubishi Magna Advance   they recently sold stood out for reliability. In the eight years they owned it they had it serviced by the book and didn't have to spend a   cent on anything else. Everything from door seals to buttons to fuel economy was as good as new! The wear and tear was minimal on things   like brakes and tyres, the tyres easily lasted over 100,000 km each   time!! Admittedly, they say, the car was plain to look at but that   was the only negative, in all other respects it was exceptional and   it's a shame they are no longer made. In Damien's view Toyota's   "bulletproof" reputation is unjustified, particularly when compared   to Mitsubishi and the Magna.LOOK FOR. Sweeping looks. Bland interior. Good-sized boot. Smooth V6 engines. Good driver. Well-built and reliableTHE BOTTOM LINEGet past the name and find a strong, well-built, reliable and   affordable car.

Ask Smithy Xtra Mitsubishi Magna mystery
Answered by Carsguide.com.au · 23 Nov 2010

That there are no warning lights coming on when the problem occurs makes the diagnosis difficult. It could be a problem with the computer momentarily sending the transmission into “limp home” mode, but I would normally expect to see a warning light when that happened. Other than that I would check the fuel injectors, and although you say they were cleaned I would have them cleaned by sonic vibration out of the car. That way the spray can be checked before and after the clean. You could also check the spark plugs and make sure they have been changed as required. The rear plugs are platinum tipped, and it’s a bit of job to remove and replace them, the intake manifold has to be removed to do it and some people baulk at the cost.

E10 consumption stretch in Magna
Answered by CarsGuide team · 21 Oct 2010

That increase in fuel usage on E10 is in line with what we've been told would happen by the biofuels people.

Magna E10 consumption
Answered by Graham Smith · 16 Sep 2010

The biofuels people told us that the fuel consumption would increase by up to three per cent on E10, but your experience certainly makes us question that. Perhaps other readers can let us know what they've experienced when they've used E10.

Ask Smithy Xtra best conversion system for Magna
Answered by Graham Smith · 12 Oct 2010

Any of the quality brands would perform well on the Magna. IMPCO made the air-valve system used by Mitsubishi on the cars supplied from the factory with LPG. It’s generally regarded as bulletproof, so that’s certainly one to consider.

Increased Magna consumption
Answered by Carsguide.com.au · 30 Sep 2010

After David McKenzie told us that his TJ Mitsubishi Magna used up   to 40 per cent more fuel when running on E10 than it did on regular   unleaded we felt we should refer it to the experts, as his experience   contradicted the advice we had received about the fuel. David's   experience confounded the experts who said it went against everything   they knew about the fuel. They told us that Mitsubishi had no   problems with the TJ Magna using E10. Further we were told that   providing the oxygen sensors were working correctly the engine   management system on the Magna would adjust for any changes in the   fuel. It was suggested that David have the fuel-injection system in   his car checked by a competent mechanic.

Ask Smithy Xtra How to choose good tyres
Answered by Graham Smith · 09 Nov 2010

Fighting your way through all the sales pitches to get the good information is always difficult and most tyre people will favour the brands they stock. Most retailers should be able to offer you a range of tyres, ranging in price from cheap to quite expensive and varying levels of performance. The Magna is a middle of the road model and I would go for a well-respected brand of tyre that has a tread pattern that offers good grip in the wet, rides comfortably and has a good prospect of wearing well. It also has to be the correct size, load and speed rating.

Vibrating 94 Mitsubishi Magna
Answered by Graham Smith · 02 Apr 2010

Unfortunately the old Magna was known to suffer from idle shake when stationary and in gear, and there's not a lot you can do to get rid of it. Owners often put it into neutral to overcome it instead of leaving it in gear at traffic lights etc. As for the hunting in gear you could check the throttle position sensor and make sure that is adjusted correctly.

Engine braking in an auto
Answered by Graham Smith · 15 Jul 2010

There's very little engine braking available with an automatic transmission, and with the desire to achieve the best possible fuel economy there have been changes to the transmissions, gearing, torque converters etc. that have further reduced the effect.
