Holden Colorado 2017 Problems

Since both variants of Colorado here use essentially the same engine, I’m not sure what sensors would be different and require changing. That said, the MY17 Colorado got recalibrated hill-descent and hill-start functions, so maybe there are some differences there.

The major mechanical difference that I can see between a 2014 and a 2017 Colorado is probably the power-steering. In late 2016, the vehicle switched to an electrically-assisted system in place of the previous hydraulic set-up. So the later engine would probably lack the pulleys and mounting hardware for the hydraulic power-steering pump that your vehicle requires. Perhaps they can be removed from the old engine and fitted to the later one.

Perhaps an easier solution would be to return the engine originally supplied and ask for the correct version for your car. If the engine supplied originally was not fit for purpose, then you’ve every right to ask for a replacement unit that is.

Was the lift kit an approved Holden fitment? I don’t think it was, I think it was done at dealer level, and that’s where you should be venting your frustration. By fitting the lift kit you have modified the car and voided the warranty in that area of the car. Remember, the dealer is an independent business, it is not part of Holden. Go back to the dealer and get him to sort the problem, and if needed call in the manufacturer of the lift kit.

It’s not possible to say that you won’t have any problems with the Colorado, and there are a lot of people who have had problems of all sorts with it. If you’re unsure, don’t buy it.

Because it is so new you need to take it back to the Holden dealer, and ramp up the pressure on them to fix it.

If need be contact Holden customer service directly and tell them the dealer can’t seem to fix it to your satisfaction, and ask that their regional service manager assess the car.

It's not an unusual requirement with a diesel with a DPF. The DPF normally cleans itself automatically without you even knowing, you don't have to do anything. But if you don't do the sort of driving that invokes the automatic regeneration you then have to take action as recommended by Holdens to do it. Diesels don't work at their best when tooling around the ‘burbs at low speed, and anyone buying one with that sort of driving routine should ask their dealer about the suitability of the vehicle for them.
