The vehicle does not downshift. It is an automatic but I have to shift into neutral between gears as well as when I need to slow down. I have had several instances of a car in front of me braking unexpectedly and I must put the car into neutral and it continues revving at a high speed so I throw it in neutral. I could run into the car in front of me unless I slam very hard on the brake or put…

What stands out
Owners have filed 30 engine complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Among the 9 model years of Ford Fiesta in our records for engine problems, this one ranks #3 by owner-complaint volume.
The failure pattern owners describe
Buyer takeaway: The 2011 Ford Fiesta engine and transmission exhibit chronic stalling, acceleration, and shift failures that owners report repeatedly across multiple dealership visits with no permanent fix—creating dangerous situations in traffic and intersections. Budget for expensive diagnostics and repairs, and expect problems to recur even after attempted fixes.
The 2011 Ford Fiesta engine complaints center on stalling, acceleration failure, and transmission response problems that pose genuine safety risks. Owners report the engine dying at traffic lights, during gear changes, and when the clutch is pressed—sometimes 30 times in 2 months. These stalls occur in intersections, on ramps, and during left-hand turns across oncoming traffic, creating dangerous situations where the car won't move when it needs to.
Acceleration failures are equally alarming. The vehicle drops speed from 60 to 40 MPH without driver input or refuses to accelerate when the pedal is pressed, sometimes entering "limp mode" that caps speed at 5 MPH. Owners describe jerking and shuddering on takeoff that feels like driving over rumble strips, particularly as the engine warms up. Multiple dealership repairs—including throttle body replacements at $880—haven't held; the problems recur within weeks or months.
Separately, owners report oil leaks from seals and the pan, inoperative cooling fans, and in one case a blown head gasket at low miles with no hard driving. One owner's engine needed complete replacement after a crankshaft seal failed; the transmission then wouldn't engage any gear. Transmission shift failures, where the car won't downshift automatically or engage Drive/Reverse, appear intermittently. Ford has not issued recalls for these issues, and service department responses range from claiming the jerking is "normal" to refusing warranty repairs until leaks worsen.

This was the certified letter I sent to Ford: on june 12, 2012, I purchased/financed a new 2011 Ford fiesta at andy shaw Ford in sylva, nc. Unfortunately, the fiesta has not performed with reliability or safety due to chronic transmission issues and has caused ample inconveniences as well as safety concerns for myself and my daughter when I am operating the vehicle. I am very disappointed…

Common questions
How serious is the engine problem on the 2011 Ford Fiesta?
It's a documented issue but not catastrophic. 30 complaints have been filed. Repairs average $3,100 and most owners catch it before it causes a breakdown.
At what mileage does the engine typically fail?
Across the 25 complaints that reported odometer mileage, most engine failures cluster between 20,000 and 89,090 miles, with the median around 58,848. A quarter of owners report trouble before 20,000; a quarter make it past 89,090. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $3,100 for engine repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to engine?
No active recalls currently cover engine issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
