Common Engine Problems

  1. Spark Plugs Stuck in Triton Engine

    Replacing spark plugs in cars has been a relatively simple task since Henry Ford mastered the assembly line, that is unless you have a Ford V8 engine from 2004-2008. Those 3-valve engines hold on to their spark plugs like an anaconda choki…

  2. Spark Plugs Ejected in Triton Engine

    Ford Triton engines are spitting out spark plugs like sunflower seeds, but the suits in Detroit act like there isn't any problem. They're wrong. We believe this defect affects the following 2-valve engines: Triton 4.6L V8, 5.4L V8, 6.8L V10…

  3. ETB Puts Escape in Limp Home Mode

    It's been a long road for electronic throttle body (ETB) complaints in Ford and Mercury vehicles. It's been an even longer road for owners with ETBs that are prone to sudden surges, dangerous stalls, and being sent into 'limp home mode' whi…

  4. EcoBoost Problems

    Ford promised a direct-injected EcoBoost engine capable of producing power while achieving better fuel efficiency. But owners generally categorize the engine as under-powered, prone to catching on fire, and subject to shaking, shuddering an…

    One of Ford's "solutions" to excessive oil concerns in the F-150 was to install new dipsticks with lowered minimum fill level markings. No wonder they're getting sued.

    A proposed class-action lawsuit says Ford needs to properly address oil consumption issues in the 5.0-liter Coyote engine.

    A couple major flaws inside the engine draw excess oil into the combustion chamber where it is burned off. Not only does this mean the engine uses much more oil than advertised, but all that additional carbon buildup causes wear on ignition and emissions equipment.…

    Ford has recalled over 874,000 F-Series trucks with engine block heaters that can start a fire when plugged into the wall.

    The automaker believes a low and unshielded mounting position is allowing road salt to corrode the heater cable’s splice connector, causing at least three known fires.

    Block heaters are made for cold climates. Road salt is too. I'm not sure how those blockheads forgot to shield those cables in the first place.

    Ford has issued a small but important electrical recall for 87 vehicles with improperly secured power supply cables.

    The cables are at the starters and alternators and the unsecured connections could cause electrical arcs. Those arcs could easily start fires.

    There are so many recalls these days that it’s no longer shocking when brand new vehicles get called back for repairs. But it really makes you wonder wire these automakers can’t get their act together.

    Puns aside, find out if your vehicle is affected here. It only takes a minute, so watt are you waiting for?

    Defective electronic throttle bodies (ETB) are causing Ford vehicles to suddenly decelerate and enter "limp home" mode, which is like trying to drive a snail through a molasses puddle.

    A lawsuit that is seeking class-action certification wants Ford to fix their ETBs.

    "The plaintiff wants Ford to pay damages and equitable relief, fix all vehicles named in the lawsuit by replacing the electronic throttle bodies, inform consumers through advertising campaigns about the dangers of sudden unintended deceleration and educate consumers about their pre-purchase or pre-lease legal rights once all the facts are known."…

    'Tis the season for holiday cookies, silent nights, a dashboard that stays lit like a Christmas tree, and frantically stepping on the gas pedal wondering why your SUV is no longer accelerating.

    OK, those last two are special "treats" for 2016 Ford Explorer owners. Owners complain about vehicles that lose power while driving, leaving drivers urgently pressing the gas pedals to no avail. Symptoms typically include seeing a "wrench light" illuminated with the words, "See Manual," all while the SUV loses speed as it enters "limp home mode."

    If this has happened to you than you'll be happy to hear an investigation has been opened to determine if a lawsuit is needed. It's not as helpful as a recall, but it's a step in the right direction. The investigation is focusing on the throttle body – a part, which many owners have told us, is not readily available.

    Each car has an EVAP system that traps fuel vapors before they escape the gas tank.

    Those vapors are stored in a charcoal canister and then, in certain situations, a purge valve opens and allows some of the vapors out to be burned off by the engine. But what happens when the purge valve sticks open?

    According to a proposed class-action lawsuit, a stuck purge valve is causing the 2012-15 Ford Focus engine to run rough and sometimes even stall. Additionally, the valve is causing problems with the gas gauge.…

    What happens when the fuel injection pump stops injecting fuel? Not much transiting, that's for sure.

    Just ask owners of the 2015-2016 Ford Transit with the 3.2L diesel engine. The automaker says the fuel injection pump may malfunction and cause the engine to fail to start or the engine may stall without warning, leaving the driver without the ability to restart the van.

    Ford didn't say when the recall will begin because that would be helpful. They did say dealerships will need to inspect the fuel system for metallic contamination.

    The engine block heaters in the 2016 Explorer are taking "warming up the car" to a whole new level ... by setting the engines on fire.

    Ford Says a "bad combination of the engine block and heater can cause the heater to catch on fire, something that has occurred at least two times in Canada. Fortunately the fires didn't cause any accidents or injuries.

    Ford didn't say when the recall will begin.

    The National Highway Traffic Safety Administration (NHTSA) has decided not to issue a recall for Ford F-series trucks that are stalling out at any speed.

    NHTSA looked at alleged problems with the exhaust gas temperature (EGT) sensors and additional problems with the calibration of powertrain control module (PCM) software.

    Maybe they should look again.…

    The National Highway Traffic Safety Administration (NHTSA) has closed their investigation into engine problems in the 2011-13 F-150 after Ford sent a technical service bulletin to dealers on how to fix the problem.

    NHTSA had received 95 complaints about the 3.5L EcoBoost engine in F-150 trucks misfiring. The misfires would only happen under humid or rainy conditions.

    The EcoBoost engine uses twin turbochargers that compress air to increase the engine's power, and what Ford found was condensation building up inside of the air cooler tubes. When the condensation is high enough, up to three cylinders can misfire.…

    The National Highway Traffic Safety Administration (NHTSA) has closed their investigation into electronic throttle body (ETB) problems in Ford vehicles after Ford agreed to fix 1.6 million of their cars and SUVs.

    Just don't call it a recall. Oh no, Ford has spun this one into a "customer satisfaction program." The program extends the warranty on the ETB for up to 10 years or 150,000 miles from the warranty start date of the vehicle and encourages owners to visit a Ford dealer to have their vehicle's software updated.

    The affected vehicles have 2.5L or 3.0L engines.

    All vehicles are eligible for the program through January 31, 2015, regardless of mileage, according to the NHTSA.

    "Owners of the affected vehicles will be contacted by mail to take their vehicle to a Ford dealer who will reprogram the powertrain control module to the latest calibration," said NHTSA in its summary of the investigation.

    A Timeline of Events

    • 2010-2012: Owners report that their Ford and Mercury vehicles equipped with an ETB suddenly surge or stall, sending their vehicles into a limited “limp home mode” that keeps their cars moving but at drastically reduced speeds.
    • October, 2012: The North Carolina Consumers Council petitioned the government to investigate problems with the throttle body in 2005-12 Ford Escapes.
    • February, 2013: The NHTSA opened a preliminary evaluation of certain Ford vehicles for ETB problems, including the 2009-10 Escape and Escape Hybrid, the 2010-11 Fusion and the 2009-10 Mercury Mariner and Mariner Hybrid.
    • March, 2014: After reviewing over 10,000 consumer complaints, the NHTSA closed their investigation after Ford agreed to -recall- open a "customer satisfaction program" on the affected vehicles.

    Owners should have received a letter from Ford, but if you didn’t, call them at 800–392–3673.

    First, Ford said to stop driving your Escape until it could get repaired. Now they're saying that "repair" probably didn't work.

    Ford is recalling 9,500 Escapes because a previous recall might not have fixed the problem. The affected vehicles were manufactured from October 5, 2011, through July 11, 2012. Ford says the engine compartment fuel line may have been installed incorrectly when repaired under the prior recall. The placement of the fuel line could cause irritation to the line and cause it to leak.

    All affected vehicles, repaired or otherwise, need to be inspected.

    Ford has been sued over acceleration issues with their V6 EcoBoost engine.

    Ford says it's related to the angle of the drive shaft. Or in Ford's words 'driveline windup'," complained the upset Ford owner. “Since they haven't been able to find a similar truck without the problem, they've washed their hands of the problem by claiming it's ‘characteristic’ of the vehicle and an ‘acceptable’ vibration. It's not acceptable to me."

    The V6 EcoBoost is an option in the 2010-2013 Ford Flex, Taurus SHO, Lincoln MKT and Lincoln MKS; the 2011-2013 Ford F-150; and the 2013 Ford Explorer Sport.

    stop driving your vehicle immediately.

    Ford said the engine compartment fuel line could split and leak fuel, which could cause the SUV to go up in smoke. The affected vehicles are equipped with the 1.6L EcoBoost engine and total about 11,500 vehicles in the U.S. and Canada.

    Ford is so concerned about these fires they don't even want you driving to the dealership for repairs. Instead, they'll arrange to have your Escape towed. Seriously.
