Instrument Cluster went completely dead, none of the gauges worked for a short period of time. The odometer went blank and all indicator lights/warning lights flashed for a moment. The gauges started working again and then went dead again. This happened several times in a 10 minute span. Then they all started working again, and has not happened in the last two days. Anyone had this happen with this car or any other Ford?

#64 of 256 07 Mercury Montego fuel system problems by vtc1

Aug 28, 2007 (6:39 pm)

I recently purchased an 07 Montego. The first time the fuel gauge was below 1/2 full and above 1/4 full, the gauge immediately went to "empty", low fuel light came on and an alarm sounded(bell).But the worse part about it is that the car acts like it is running out of fuel when it really isn't. I took it back to the dealer and their techs said it was bad sending units in the gas tank. These were replaced. Next time the gauge read 1/4 full, the same thing happened. So the dealership filled it up again and it happened again and this time it happened between 1/2 and 1/4 full.The engineers said this was normal! When is it normal for any vehicle to display any kind of low fuel alarm when there is still six gallons of fuel in the tank? I can understand an indicator on the dash(maybe).But to act like it it going to stall when there is plenty of fuel is a different matter. The engineers have no clue. Does anyone have any ideas? This is a brand new car. I guess I might have to take it back and stay away from Ford products altogether.Anyway, any suggestions?

try geting a fuel system cleaner with techron in it.
 
Sulfer in the gas plays havoc with the Ford sending unit.

I already tried a different brand of fuel besides what the dealer had. Same problem.

Just using different gas won't get it out, try using a fuel system cleaner. If it doesn't work you are only out $11.

#68 of 256 Throttle Body at 34K by chuck1

I had a problem a couple of weeks ago with my '06 Five Hundred. I stopped at a store to get a soda. I came back out and started the car and then it "shimmy and shook" and then the check motor light came on. It then didn't have any power what so ever. The dealership later stated that it went in to a "limp home" mode and that is why it didn't have any power.
 
I was told on Saturday that the throttle body went out and the part would not be in until Wednesday.
 
Let me say that this car is a company provided car. That being said - if this is the best Ford can do in a full-size car it's pretty sad.
 
 Good enough - isn't in todays highly competitive market. I have never had a part like this go out in any car I have owned. More less one with 34,000 miles on it.
 
If I had to make a choice in a car - or if I had a choice for a company car, it would be an Accord or Camry!
 
Enough Said!!!

Yeah, I'm sure that there's never been an Accord or Camry with a similar problem at the same mileage.

Well - you can say one thing...just look at the number of sales of Accord and Camry and compare them to the 500 - it's not even close.............

According to the latest JD Power survey, the Milan came in first with the least problems in the first 90 days of ownership. Accord came second, Fusion and Mitsu Galant tied for third. Camry finish where? They didn't say.
 
Chevy sells lots of Impalas, that doesn't mean they are good cars.
 
You don't even know if Ford made the throttle body of it a supplier did. Sure it was a Ford design but by every study done out there on quality, Ford is in line with or exceeding the Japanese competition.
 
Just think about how man times your computer crashes and you just shrug your shoulders...thats they way Windows is and we accept it. Even the worst car doesn't misbehave as much as the average home computer. Try to put things into prospective. Especially since you are still under the new car warranty.
