Holden Problems

This could be the result of a worn or poorly adjusted transmission, a worn torque converter or even something simple like a low transmission-fluid level. So that’s job one: Check the level of fluid on the dipstick. If that’s okay, you really need to see a transmission specialist who has probably seen these exact symptoms before. What I can tell you for sure is that the automatic gearboxes fitted to Holdens of this era did have a finite lifespan before they needed either an overhaul or outright replacement.

But make sure your mechanic checks that the cause of the vibration is not a worn universal joint or bent axle or an out-of-balance drive-shaft. Even a sticking brake or a worn engine mount can induce vibrations into a moving or accelerating car, so rule all that stuff out first.

That price is towards the top end of things for this particular make and model, but within reason given the low kilometres on the odometer. Make sure it has a full service record as, even though it hasn’t been used much, it will still have needed proper servicing if it’s to remain reliable.

There are many, many things in a modern cat that can cause the check-engine light to illuminate. The cause could be anything from a sensor somewhere on the engine or in the exhaust to a problem such as low oil pressure, overheating, a dud fuel-injector or even a stretched timing chain that has allowed the crankshaft and the camshafts to become out of synch.

Basically, the car’s computer notices and logs anything that’s amiss and warns the owner that some form of servicing is required by lighting up the check-engine light. The other possibility, of course, is that whoever worked on the emissions control system you mentioned, may have neglected to manually turn off the check-engine light. It’s happened before.

Potentially, this can be fixed by a specialist, but in reality, it’s probably going to be cheaper and simpler to fit a better stereo head unit and pick up a few modern features like Bluetooth and smart-phone connectivity. These units are relatively inexpensive to buy and there’s lots of choice out there. Consider upgrading the car’s speakers at the same time for an even better listening experience.

The biggest issue owners have experienced with this car is a tendency for the engine to consume oil and require a top-up between oil changes. Holden addressed this by changing the specification of the oil from a 5W30 to a 5W40 oil and released a new oil cap design. You’ll know if the new-design oil cap is fitted to your car as the owner’s manual will have been altered by a Holden dealer to reflect the new oil specification.

Beyond that, the biggest driveline complaint seems to be the noise generated by the engine. However, this seems to be a natural by-product of the 2.8-llitre turbo-diesel fitted to the Colorado 7 and is not a fault per se.

Holden’s factory maintenance schedule for the 1.8-litre Trax suggests a 150,000km (or 10 years, whichever comes first) timing belt change interval. Don’t forget to change the relevant tensioners and belt idlers at the same time. Many owners also elect to replace the water pump at the same time while this area of the engine is apart for the timing belt change.

The turbocharged 1.4-litre version of the Trax used a timing chain rather than a timing belt. This chain should be good for the life of the vehicle.

When things like a car’s lights start to develop a mind of their own, the car’s body computer is sometimes the root cause. This is the computer that controls everything from the central locking to the lighting and the climate control to the cruise control, as well as a lot more in between. If this computer module starts playing up, all sorts of weird things can take place, including the dashboard lights coming on of their own doing. If this happens overnight or when the car is parked for a long period of time, it could easily drain the battery and leave you with no electrical power.

An auto electrician is the obvious solution, but try this trick at home first. Remove the negative battery terminal on the car and leave it disconnected for an hour or two (or, even better, overnight) this is sometimes enough to reboot that body computer and return the car to normal operation. Be aware though, that even if this fixes the problem, it may recur sometime down the track. But at least then you’ll know what to do next time.

Your mechanic is right in deciding that a leak between the engine and gearbox will need the two components to be split to access the problem. Whatever it turns out to be. It could be a broken torque converter which would be expensive, or a simple oil seal which may cost just a few dollars. Either way, though, the labour involved in fixing even that cheap oil seal is going to make this an expensive operation.

Sometimes, you just have to let it go and cut your losses on a car that is starting to become worn out. To be honest, the Holden Captiva was not the most reliable or durable car ever made and many owners have discovered the hard way that this Holden badged car was actually a Daewoo, and not a good Daewoo at that.

Fault code P0014 is, indeed, a problem with the engine’s camshaft timing. It’s also a very common one on these late-model V6 Holdens. Your engine doesn’t have a timing belt, instead using a timing chain which, theoretically, should be good for the life of the car. Unfortunately, in this V6 engine, the timing chain was under-engineered and many owners have found out the hard way that the timing chain needs replacement at relatively low mileages.

The fault code shows up when the car’s computer can’t make sense of the relationship between the engine’s crankshaft and camshafts. That’s because when the timing chain stretches, that relationship varies and the engine’s valves are no longer opening and closing precisely when they should. At that point, the computer throws its hands in the air and triggers the fault code and check-engine light.

The only real fix is to replace the timing chains. The cost will vary depending on what else needs to be done and who carries out the work, but even at its cheapest, this job could easily run into the $2000 to $3000 region. Industry wisdom also suggests that you also replace the timing chain guide and oil pump at the same time.

The official oil recommendation for this vehicle is a fully synthetic 5W30 grade oil. If the engine is in good condition, this is the best oil to use. The X-factor in all of this, of course, is the relatively high mileage your car has covered. As engines wear, and perhaps begin to consume a bit more oil between oil-changes, the conventional wisdom has been to use a slightly thicker oil. A 10W40 would be the logical choice here.

But the turbocharged Cruze engine, like a lot of modern engines, uses some pretty fine oilways that may not be compatible with the thicker 10W40. Examples of this include the oilways that lubricate the turbocharger’s bearing and also the ones that allow the variable valve timing to operate properly. Unless the engine is showing real signs of wear, sticking with the 5W30 oil is definitely the best advice.
