I have an issue with my vehicle or a particular dealership. Who should I contact?

If it relates to the servicing or maintenance of a vehicle, you should discuss the matter with the Service Manager of the dealership. If your issue relates to a vehicle sale, then you should speak to the dealership’s Sales Manager.If you can’t resolve matters after speaking to either the Service or Sales Managers at the dealership, you should discuss your concerns with the Dealer Principal.
If the Dealer Principal proves unable to help, please contact Isuzu UK by registering a case.

Can I use Bio-Diesel in my Isuzu?

No. Isuzu only recommend diesel that meets European standard EN590. Fuel that does not meet this standard can cause injector damage, oil dilution and on the D-Max with the Euro 5 engine it could cause DPF problems, oil dilution and frequent fuel filter issues.

What gear should I tow in?

As towing requirements and conditions can vary significantly there is no right or wrong answer although the recommendation is to choose a gear that maintains optimum torque while not compromising fuel economy. The gear selection should be made to keep the engine RPM between 1800rpm and 2500rpm, this way the engine is not ‘over revving’ but maintains peak torque output. When pulling away, do not over use or consistently slip the clutch.

Is my vehicle eligible for the 3.5 tonne upgrade?

To find out if your vehicle is eligible to tow 3.5 tonnes please contact your dealer who will be able to advise you.

Why should I choose genuine Isuzu service?

Your local Isuzu dealer has invested a great deal of resources into looking after your Isuzu vehicle. Authorised Isuzu dealers and Authorised Service outlets are the only servicing outlets to have the specific tools, equipment and electronic media to be able to support Isuzu vehicles.

Your authorised dealer also has available to them, Manufacturer training and direct contact to Isuzu UK‘s Technical Support personnel. All of this provides peace of mind motoring. All genuine parts supplied by Isuzu UK and fitted by an Isuzu dealer, excluding wear and tear and service items also benefit from a 3 year, 60,000 mile parts and labour warranty.

If I service my vehicle with an independent service centre will this affect my warranty?

No, servicing your vehicle at a non-Isuzu approved service outlet will not adversely affect the warranty on your Isuzu. However, the maintenance must be completed in accordance with the manufacturer’s recommendations and the service parts used must be of equal quality to original components and fluids. The replacement parts and fluids MUST comply with the specifications as shown in your owners and drivers manual.

Any failure of genuine components found to be caused by non-genuine parts is not covered under warranty.

How often do I have to service my Isuzu?

All service schedules are printed in your service and maintenance book. Please ensure that your servicing is carried out in line with the servicing as stated in your service and maintenance book as failure to do so can invalidate your warranty.

In addition to regular servicing, some extra items may require attention depending on operation and usage, please refer to ‘severe driving conditions’ as found in your service and warranty booklet.

What type of oil should I use?

This commonly asked question can be answered by locating the ‘service and maintenance’ section within the owners and drivers manual. This section lists the required lubricants and types suitable for Isuzu vehicles. If your vehicle does not have an owners and drivers manual, you can purchase one from your nearest Isuzu Dealer.

Is my clutch wear covered under warranty?

A drive plate (also known as a clutch disc) has a friction material surface very similar to brake pads. These friction materials will wear under normal driving conditions and are considered a consumable item.

What Should I do if I have a warrantable concern?

To obtain warranty repairs, take the vehicle to an authorised Isuzu dealer within the warranty period, present suitable identification to verify and request the needed repairs or adjustments.

My warranty has expired but I would like to request some ‘Good Will’ from Isuzu UK.

In all circumstances you will need to present the vehicle to an Isuzu dealer with all supporting documentation such as service history and parts invoices if you have them. You will be required to authorise them to investigate the cause of your concern. If your claim for ‘good will’ is denied the cost of diagnosis and or repairs will be chargeable to you.
