Holden Problems

Without hearing the car firsthand it’s impossible to speculate on what might be wrong with your car, but I would suggest that it’s unlikely to be the spark plugs. Your best course of action would be to get a mechanic to check it for you.

You can’t. It’s filled with fluid in the factory and that’s it for the life of the car. If you want it checked or changed an automatic transmission mechanic could do it for you.

They are probably blocked. Clean the nozzles out and make sure they are clear and flowing freely.

The GMC (and Holden) Acadia is built in the Spring Hill assembly plant, in Tennessee, USA.

Holden is at least showing a desire to fix your car, and getting the engineers to look at it would be worthwhile, but it must getting to the point that the car should be called a ‘lemon’ even though we don’t have such laws in this country. If this had happened in the US there is little doubt that the car would have been replaced or you would have had your money refunded. I would be looking to come to an agreement with Holden to get out of the car.

The GMC Acadia is 4917mm.

It sounds like it could have the dreaded Cruze auto transmission problem. Take it to a Holden dealer, or an automatic transmission mechanic and have them check it.

The best source of that sort of information is the Federal Chamber of Automotive Industries (FCAI). You could also ask Ford and Holden.

The GMC Acadia doesn't enjoy the reliability of its Japanese competitors, but when properly maintained and driven sympathetically, it should not have any major reliability dramas.  

Never let things slide if you feel your car has a problem. Pursue a solution until you are satisfied you have the answer. It’s not a good idea to miss services, particularly on cars with turbochargers. Keeping a fresh supply of oil is the key to trouble-free motoring with turbos. There’s every chance the turbo was faulty when you first noticed it, and having missed a service you probably contributed to the failure. There’s probably not a lot you can do, except to pay for the repairs.
