Had the fuel pump replaced on our '08 Limited when the original whine became unbearable. Replacement ran fine for a few weeks, now whines just as loud as the first. Dealership hands are tied since Ford have no solution to offer. Young folks sitting in the rear of the car find it nauseating (yes - really) as they are more susceptible to high frequency sounds. Love the car....but this, coupled to an ignition detonation knocking issue that we have had from new and also seems beyond Fords ability to solve, will herald the end of our Edge ownership. Sorry Ford, you just lost an Edge customer who really, really wanted to like this car. It is your support of the dealer that is lacking here, not the dealership's fault as the problems "are within manufacturers spec and tolerances". Dissappointing.

We just had the fuel pump replaced after complaining to the dealer service techs about the high pitched whine after 23000 miles on an '08. New pump makes exactly the same noise. So what now??......

So....my saga continues. Experiment with 93 octane gave only a temporary reprieve to the pinking before it returned. Went back to 87 regular octane and its back in all its glory (sounds like the proverbial bag of spanners when the engine is put under demand in low gear). Weekend trip to the hill country round Austin gave the engine some challenge and the pinking was worst it has ever been. Returned to dealer (4th attempt to fix) and this time they consulted with Ford. They have asked me to "baseline" the fuel my running three tanks of Shell or Exxon regular 87 octane - after which they will review again and decide what to do. Will let you know what happens after that. Did anyone else pick up on the recent USA Today article that quoted a technical guru from Ford talking about the "octane sensors on the LKX and Edge that would soon become more widespread"?? - he went on to describe how that would allow the engines to tune automatically to the octane used for best performance and mpg. Sounded awfuly suspicious to me that such a system on my own Edge might well be close to the source for my pinking issues. Dealer knew nothing about it.

Filled up with Premuim 93 octane at the weekend for a test and in the process of running a tank through. The valve pinking is GONE! .....and it runs beautifully. No adverse affects (other than in my wallet), no pre-detonation at the higher end of the rev range - actually feels like there is more power too. Leads me to one of two conclusions: Either the fuel here on the Gulf Coast does not live up to its octane rating as posted on the pumps - or Ford have incorrectly quoted the Duratec 35 motor as compatible with regular 83 octane. Now I might have believed that fuel would be affected by Hurricane Ike - as refineries get back up to capacity and product variability might be mixed. But the pinking started for me before the storm and within the first 1000 miles break-in period. We also used different brands of regular gas to see if that made any difference - it did not. The Owners Manual does carry a 'catch-all' phrase in there warning of "occasional valve noise" due to variability in fuel octane. But from a customer perspective that is hogwash. If a motor is advertised to run on 83 then it should run properly on 83 - and that means no pinking. I will most likely put this experience to paper and send a letter off to Ford (with little to no expectation of any satisfactory reply). I want to be sure I cover all the bases for any potential trouble further down the road. For now though, this Edge is Premium fuel only - and it loves it!

So my Dealer had the car for the weekend and had their "best Tech' look at it. They confirm they can hear the valve noise I am talking about but suggest no further action at this time. They quoted from the Owners Manual to me - words about "...occasional noise ...under normal driving conditions.." due to variability in the fuel octane. Not sure I quite buy into that. Did not hear the same valve 'tink' on other Edge's I have been in. Will let it ride for another few thousand miles - but after that I will go straight to Ford and get an Area Rep to see/hear the car. May do so earlier if the noise persists or gets worse. I have owned 9 Fords - not one of them ever displayed this issue. At least I am building a history of this at the dealership so I have something to fall back on. I am no trained service technician - but I have driven enough vehicles in my 35 years on the road to confidently identify a mechanical issue with valves when I hear it. I predict it will only get worse. P.S. my first oil change to a full synthetic was at 1500 miles and well after the valve noise had first become apparent. Dealer service sheet records my request to investigate the noise when performing the oil change.

My new '08 Edge Limited with Duratec 35 engine has ominous valve noise. This is intermittent in nature, not heard when the engine is cold, but usually appears when the engine is under load at lower rpm. Mentioned it at 1st dealer service, response was 'we couldn't hear it'. Second visit then convinced both the service rep and a technician when I took both for a test drive. We were able to replicate the valve noise (sounds like pinking..."tink, tink, tink') on the service lot with the hood up - when the car was power-braked (i.e. car stationary, brake firmly on and rev the engine). Issue is now with the dealer Sales Manager for consideration. My take is I could have a Lemon on my hands. I would not be very happy to have the engine broken down for repair with ony 3000 miles on the clock from new - just not willing to accept that. Note that I changed out the oil at 1500 miles for a full synthetic (exceeding Fords minimum specs). The noise became apparent from first taking ownership - within days of driving it off the lot. The best the Ford Tech could suggest was to try adding a fuel additive (which I am not going to do). I did try using a higher octane fuel to see if the noise might be related but no change. The dealer had not had any such issues with their Edge customers. But from reading here I am not alone perhaps. Will post any further developments. Otherwise - delighted with the car and simply want one that perfrorms as Ford intended.
