Ford Focus Zetec - ECU failure not covered by warranty - Donna Reed

My son lease-purchased the above vehicle new on July 10th 2014. Over the next 3 years the car was perfectly maintained and serviced according to the Ford service book recommendations.

On June 28th 2017, 13 days prior to the warranty expiration date of July 11th, the car broke down in Swindon and it was transported to our home in Hindhead by the AA. The following day, when I called Ford in Guidlford to seek advice on what to do next, I was informed that this problem would “not be covered under warranty” and I could get it towed to any local garage. It was taken to Liss Garage Services, who have been servicing and repairing our family’s vehicles for many years.

Stewart Roberts, the proprietor, suspected a problem with either the ECU or a fuel injector, but told me that the engine was so badly damaged that it would need replacing, which he did at a cost of over £3,000. On testing the car following this, the replacement engine failed and a third engine was installed. Alex eventually recovered his car on October 24th 2017.

The car’s engine started misfiring again in November, and Stewart suggested taking it to Ford in Guildford for a full diagnostic test. The car was taken in to them on November 23rd 2017 (mileage on the clock at that time was 31,440). On December 7th Ford finally informed us that they were unable to diagnose the problem without it costing a further £627.98 (£400 to flush the cooling system of oil residue – which Stewart had already done whilst replacing the engine(s)) and £227.98 for performing diagnostics for an injector or PCM problem). We declined to pay these costs, collected the car from Ford on December 18th 2017 and were charged £42.49 – a ‘token gesture’ of a 50% discount for a “Vehicle Health Check”.

At the beginning of February 2018, the car again showed signs of rough running and was taken to Liss Garage Services. Stewart checked the wiring to the fuel injectors, which was fine and so he suggested having the ECU tested and if necessary replaced. This was done at a cost of £760.20.

My son finally sold the car at the end of February for £5,600. It was less than four years old, and with less than 32,000 miles on the clock!

I am appalled that Ford mis-informed me about the warranty situation, and that we have had to finance over £3,700 worth of repairs to a vehicle that is less than 4 years old and has less than 32,000 miles on the clock. It appears, however, that this is not a isolated case with Focus Zetecs….

Oh dear.

Hindsight is a wonderful tool but surely first reaction to an assertion that ECU is not covered by warranty is to check documentation and see if it is. Was that check done?

Secondly once your indy had diagnosed the engine FUBAR did anyone go back to suppling dealer?

What was reason for failure of both first and second engines. Was some anciliary component transferred which caused the failure.

What remedy are you looking for now?

Ford in Guidlford to seek advice on what to do next, I was informed that this problem would “not be covered under warranty” and I could get it towed to any local garage.

And you believed them? Did you read the warranty T & C's, did you speak to Ford themselves to check. Ford excludes certain items from their warranties that they class as trim (its a long and bizzare list) but the engine ECU is not trim.

Basically you have been taken for a ride by your local Ford dealer (who other than selling Fords has nothing to do with them) and more so by your trusted garage.

I cannot see what you can do other than consider legal action but what that action would be needs expert legal advice from a specialist solicitor and not members of a Forum.

I wasn't aware of this until after I took ownership of my B Max, but Ford dealers (perhaps ALL dealers, I don't know) exercise a degree of autonomy when it comes to interpreting the terms of a Ford warranty.

They adhere to the Humpty Dumpty defence, which can be summed up thus: "a word means just what I choose it to mean--neither more nor less".

Still worth asking, though.

It seems strange the OP's son didn't take the matter up with Ford UK Customer Services as it's not the dealer who decides, it's Ford UK in this case - dealers can't/won't do warranty work until they know they're going to be paid and the variance in attitude to customers is quite marked - some dealers stone-walling to avoid warranty at all costs to save the car maker money while others will put forward the customers' case to the maker with vigour - fortunately the market is moving towards the latter but it's slow going.

I've been fortunate with my choice of dealer over the last 20 years, more by luck than design - back in '97 my local Vauxhall dealer supported my out of warranty claim for a wrecked engine as Vauxhall had changed the timing belt interval from 80,000 to 40,000 miles but didn't tell existing customers - in '02 a different Vauxhall dealer supported my issue with Vauxhall over suspension settings - in '14 my Hyundai dealer was proactive in getting approval for an engine rebuild - and in '16 my VW dealer was proactive in obtaining a like-for-like courtesy car for a special trip as well as an excellent warranty extension deal FOC.

It would seem the OP's son used what I would class on old-school dealer from the '70s.

Dealers do vary hugely on competence. Bypass them and take the matter up directly with Ford customer services in a polite but firm manner. I had to do this with Honda when the dealer refused to accept the badly juddering clutch on my CRV was faulty. Three visits and three different excuses from “it’s a characteristic of the car sir” to “it’s due to your driving style” via “we can’t find fault with it.” Honda immediately had it returned to be properly checked then the clutch was replaced without further quibble.

I’ve found our local VW Dealer the polar opposite with several out of warranty goodwill claims made on my behalf without me having to ask on the last two VW’s I’ve owned. Cars are also always returned spotless inside and out.

Had a water pump fail on a Golf. When I collected it he told me that they would submit a goodwill claim, told them not to bother since it was still under warranty. They apologised and I left without paying. 3 weeks later a cheque from VW arrived on my doorstep. Did I phone up and say i don't want it, don't be daft banked it before the realised.

Obviously the garages and VW's admin leaves a lot to be desired.

Does that mean that it was maintained outside the Ford dealer network ? If so, then you may have missed TSBs (Technical Service Bulletins - which are issued to dealers to correct faults in cars coming in for service). It's difficult to get a dealer to handle warranty work when the car's been serviced outside their network. I've had excellent service from Vauxhall (in the 1990s) in this respect (that was an ECU failure), but not Ford. It's good news that your son has now sold this car, although Ford won't be interested in any calls now.

It's usually a good idea to keep the car serviced by the dealer while it's in warranty, even if some other jobs are done by trusted independents.

This bit is confusing me. Why would a faulty ECU or injector lead to severe engine damage?

And how would the Ford Dealer know it was not under warranty when they hadn't even looked at it??

Ford Focus Zetec - ECU failure not covered by warranty - SLO76
I may be very wrong here but I suspect the situation here is that the car has been serviced by a non-franchised dealer which may indeed save £50 or so per year but unfortunately it is almost impossible to claim on any manufacturer warranty as the firm will demand proof that it has indeed been maintained exactly in accordance with their schedule using manufacturer parts and including any actions required by technical bulletins. Non-franchises workshops will find it pretty much impossible to prove this so the warranty claim will (rightly in my opinion) be rejected.

Small backstreet garages lack the up to date training, the access to technical information and the diagnostic tools to maintain the latest highly complex engines so it’s understandable that any claim would fail.

Donna, it would help if you post again with some more information.

You say 'Over the next 3 years the car was perfectly maintained and serviced according to the Ford service book recommendations.' Does this also mean that Liss Garage Services also used genuine Ford parts when doing the services? This could make a difference as to whether Ford honour their warranty.

If the answer to this is yes, what are Ford's reasons for saying that the repair wouldn't be covered?

This story beggars belief, unless someone can explain how ECU failure (and they virtually never fail unless submerged) can wreck an engine.

I suspect the true story is that it ran out of oil. I also suspect there will be no reply from the OP.

Ford Focus Zetec - ECU failure not covered by warranty - Gibbo_Wirral

From my experience, ECU failure usually means the same - failure through water ingress, or through an electrical spike with a jump start.

If the part was faulty for some time before complete failure I'd expect it to work in a default mode (maybe limp mode without the speed limit?) and the car to be drinking petrol and be immediately apparent.

This sounds like a 'diesel of doom' saga - although OP doesn't mention fuel type. I can't see how the ECU would cause engine failure, unless it had been reprogrammed (to remove the DPF at these low mileages?) I suspect that Ford refused warranty work after hearing the AA patrolman's diagnosis, even if 2nd hand.

Sensors/actuators - especially injectors, could destroy the engine and maybe the ECU was just indicating the failure ?
