No joy on sooty Navara
I BOUGHT my D22 Nissan Navara ST-R in 2010. It was six months old and had done less than 50,000km. I immediately noticed a smoke problem. At 2800rpm or more it produced large amounts of black smoke until a constant speed was reached. Nissan had the dealer look at the problem and after being called in no fewer than a dozen times concluded that the smoke is not smoke but soot and they can do no more. Surely soot is a problem in itself and would exceed EPA guidelines. Nissan says, via the dealer, it’s done all it can. What should I do now? Peter Ritchie, email Nissan’s response isn’t acceptable and you’re right, the EPA would probably put your car off the road if they saw it. It isn’t normal, and sounds as if it’s getting too much fuel when accelerating. I would have a diesel engine specialist check it; I’msure they would be able to find the cause of the problem for you. NEGATIVE GEARBOX I read with interest about gearbox overheating problems in Toyota utes and wonder if this also applies to the latest Prado with the same D4-D engine. I towed a six-metre caravan to Queensland and back over three months with my 2010 Prado GX. Going up the Adelaide Hills the gearbox overheat warning light came on, much to my consternation. However, as we were nearly to the top we carried on and once over the light went off. There were no serious hills to negotiate until we came to the horrendous climb on the road between Batemans Bay and Canberra in NSW. The light came on again and I was forced to stop four times in some fairly precarious places to let the gearbox cool down. When we finally made Canberra we went straight to the Toyota dealer who advised that they knew about the problem and it was fixed by a re-programming of the gearbox computer. We had no further problems for the rest of the trip, but I must admit to being a bit sceptical about the computer fix and would like to know if any other complaints of this nature have surfaced. As we are considering another trip, would it be prudent to put an oil-cooler on the gearbox? I hasten to add the loaded weight of the van was 2350kg and under the 2500kg limit Toyota advertised. Apart from this glitch, the vehicle performed brilliantly.
Mal, email Your experience is not uncommon. We had a number of reports from HiLux owners in the year or so after the ute was launched but we thought the reprogramming of the computer had fixed the issue. Perhaps it hasn’t. Talk to your Toyota dealer, and also get the advice of an auto transmission expert about fitting an external oil cooler. If you plan to travel over hilly terrain on your next trip it would be a good idea to fit an extra cooler. EVO X RATED At the end of January I bought a 2008 Mitsubishi Lancer Evo X from a dealer in Melbourne. I shook hands on the verbal agreement that prior to delivery they would repair the wheels, which had all been badly gouged by the previous owner. They did not do this, they then delivered the car with about 86,000km on the odometer when they had advertised 83,000km, and now a number of other faults have come to light. Of greatest concern is a rattle in the engine in the vicinity of cylinder three. I advised them of the faults
