Victorian Civil and Administrative Tribunal
2017-10-13
Original judgment source is linked above.
Claim for new engine after major failure - claim includes additional expenses incurred and costs of the proceeding - cause found to be the failure of the piston rings not bedding-in correctly - applicant successful - supplier of vehicle ordered to replace engine.
Chequered Flag Motors Pty Ltd (ACN 007 047 305) trading as Lance Dixon
Jaguar Land Rover Australia Pty Ltd (ACN 004 352 238)
Bennett v Chequered Flag Motors Pty Ltd (Civil Claims) [2017] VCAT 1671
Road tested vehicle - no noise evident. Inspected fan belts and engine fittings - all ok. Unable to fault at time of testing. Customer to monitor, if fault persists customer demonstration will be required.
Tested operation - could not fault at time of testing. Checked faults - none logged.
Carried out XF 2.0L petrol 12 month/16,000km "A" service as per manufacturers specification.[3]
Inspected engine light on concern, found misfire within engine. Completed compression test of engine cylinders and found number 1 had reduced compression of 45PSI. Remaining cylinder have 170PSI compression. Carried out leak down test and found leakage through piston and piston ring area.
Requires replacement of engine due to internal damage.
Completed formal goodwill request to Jaguar Australia due to vehicle warranty expiring on 25/12/15, submitted above report and service history.
Goodwill requested rejected based on insufficient justification for goodwill.
JLRA refused goodwill CRC case number 13804088. Towed vehicle back to customer as goodwill from Lance. No charge on cost of diagnosis.
Cost of replacing engine with new assembly approximately $37,500 inc GST.
Customer requested report, contact Jaguar Australia and created case file on customer issue #13804088.
"We believe the damages listed in our statement of claim to be fair and reasonable and are the direct result and consequence of your representative dealer Lance Dixon failure to correctly investigate and diagnose the cause of the damage to our Jaguar engine, and on the basis of this incomplete inspection and incorrect diagnoses declined responsibility, thereby forcing us to be exposed to the costs of having the engine removed (Pickards Automotive) and engaging an independent automotive engineer and expert witness (Mr RA Chapman) to dismantle and inspect the engine to diagnose the exact cause of failure.
Further your failure to inspect the engine after it had been dismantled demonstrated your lack of interest in discovering the true cause of failure, a point that would be made clear to the Tribunal."
The principle cause of failure of the subject engine was as a directly (sic) result of the piston rings not bedding-in correctly after the engine was first assembled by the manufacturer.[8]
In my opinion it was the failure of the piston rings to effectively 'bed-in' to the cylinder bores which displayed a surface condition totally inconsistent with a vehicle which has travelled only 31,000kms.
The failure of the piston rings to effectively complete the 'bedding-in' process is the result of an incorrect ('cross hatch') honing finish having been applied to the cylinders bores at the time of manufacture or faulty piston rings fitted by the manufacturer during engine assembly or possibly both.[9]
A comprehensive mechanical examination and independent expert oil analysis of the subject engine has established to my satisfaction that the omission of a basic service upon a prescribed date had absolutely no bearing on the failure of the subject engine.
The 'Bedding-in' process should have routinely occurred within 5,000km travelled from new and most certainly by the time the first service was performed at 9,132km.
I have not seen any evidence which would suggest the owner has contributed in any way toward the failure of the piston rings to 'Bed-in' or the pitting damage noted upon the cylinder bores.[10]
The consequence of bedding in would sometimes be high oil consumption or unsatisfactory performance of the vehicle, those sort of things. It may not be apparent to the driver or owner of the vehicle that this hasn't happened, it's more that the service department would probably pick it up when they changed the spark plugs, they would see evidence. This was a very wet engine, all inside of the cylinder head, of the combustion chamber was all wet. So it would have been evident.
"Well this engine is fitted as you know with knock sensors so when the engine senses detonation that's recorded .... so if low octane fuel was used in it, the knock sensors would have recorded that and prevented it from detonating. But of course the performance of a car would be notably reduced"
"Yes they would to some degree - but there was so much oil in there that it would only take one second or half a second of detonation to produce that temperature and that pressure which is what has caused that piston to burn. And that oil has been in the engine for a long time, the rings have never been healed and so it was quite preventative for that to ...occur"
So are we talking a one off event here or was it happening gradually over time?
"Well I would say it's probably a one event that has burnt that piston like that - it only takes seconds, a matter of seconds to burn".
"No I don't believe so - no - because of the knock sensors. If you put 91 octane fuel in or whatever the lowest fuel is, the knock sensor would just drag the ignition timing back, so that as soon as it heard it detonate once, it would drag it back until it couldn't detonate any more and prevent that damage."
[1] While the application was made in the name of Andrew Bennett, the proper applicant is Mrs Bennett, as owner of the vehicle. The issue was raised during the hearing, and there was no objection to the application being amended accordingly.
