There Is A Design Flaw In The Washer Used At The Transmission Fluid Junctions In The Radiator. The Fittings And Washer Are Made Of Dissimilar Metals. As A Result, The Steel Washer Used As A Spacer Rusts And Corrodes, Then Swells And Forcibly Pulls The Threads From Their Fittings. A Catastrophic Loss Of Fluids Including An Exchange Of Transmission Fluid And Engine Coolant Take Place, Rendering The Vehicle Not Only Inoperable But Also Perhaps Significantly Damaged. These Fittings Fail At Random With No Obvious Pattern Or Environmental Cause. The Normal “underbody Rust” Does Not Seem To Correlate With This Failure. I Have Done Substantial Research On The Internet Regarding This Issue, And Many Others Report This Type Of Failure And Have Come To The Same Conclusion. I Feel This Is A Significant Safety Issue With This Vehicle, As Such A Dramatic And Immediate Loss Of Fluid Could Result In Engine Failure, Overheating, And Transmission Failure. If The Engine Were To Fail And The Vehicle Were Traveling At Speed, A Loss Of Power Steering And Power Assisted Braking Would Occur. Additionally, Finding A Location To Pull Off Of The Road Presents A Safety Hazard In Itself. This Issue Could Be Easily Resolved By Ceasing To Use Dissimilar Metals In The Radiator Fittings. As Far As I Know, This Same Design Is Being Applied To All honda ridgeline Model Years Including Those Currently In Production. Although I Cannot Verify This, I Have Heard That This Particular Part In The 2009 Model Year Remained Unmodified. This Is An Issue That Must Be Addressed, As There Are More And More Failures Of This Type Occurring. It Is Simply A Matter Of Time Before A Serious Injury Occurs That Could Have Been Completely Preventable. *tr

Found Out Radiator/transmission On honda ridgeline Has Been Having Catastrophic Failures Due To Transmission Line Failure. This Issue Will Cause Engine Failure That Could Result In Wrecks Due To The Violent Nature Of This Failure. This Would Cause Immediate Panic To My Pregnant Wife And Soon To Be Newborn Baby Girl. honda Is Aware Of The Faulty Connection On Radiator That Causes This Issue And Still Hasn’t Issued Recall. I Believe They Are Acting Negligently Towards Fixing This Issue. Come To Find Out Nissan Had A Similar Issue With Their Pathfinder And Has Since Performed A Voluntary Radiator Assembly Program (http://www.nissanassist.com/web/radiator/faqs.php?menu=22). honda Also Directed Us To Contact Nhtsa And I Am Hopeful That The Fine Staff At Nhtsa Will Take A Close Look At This Issue With honda And Come To A Decision To Help Consumers Take Preventative Measures. Thank You For Taking Time To Read This And I Hope You And Your Family Do Not Have To Experience This Type Of Issue. *tr

2006 honda ridgeline With 140,000 Miles. All Scheduled Maintenance Performed. Driving Home On 9/18/13 On Highway, Cruise Control Set To 65 Mph, Car Began To Lurch Forward A Few Times. Got Off At Next Exit And Revs Began To Rise As If In Neutral. Stopped Immediately And Called For Tow Truck. Noticed Temp Meter Was High, But Went Back Down To Normal Within 15 Minutes. “strawberry Milk Shake” Type Liquid Then Poured Onto Pavement. Truck Towed To Independent Service Station. The Station Concluded That There Was A Failure Of The Transmission Cooler, Which Resides Within The Radiator. Apparently The Metal Connector That Separates The Two (chemically Incompatible) Coolants Corroded, The Fluids Mixed Causing The Temp To Rise And Boil Over, The Mixture Of Coolants Apparently Destroys Both The Radiator And The Transmission. Service Tech’s Have Rarely Seen This Before On Older Toyota 4runners, But Not honda‘s. However After Some Research, There Are Dozens Similar Incidents Reported On The Various honda Forums Which Indicate honda‘s Awareness And Refusal To Issue A Recall Or Assume Financial Responsibility For The Catastrophic Failure That Results (like My $5,765 Refurbished Transmission, New Radiator, Hose Flushes, Etc.). There Are No Warning Signs For This Type Of Issue. Fortunately I Was Able To Pull Off In A Safe Place, But Injuries Can Surely Result From This Preventable Problem. I Have Begun The Process Of Requesting Financial Assistance From honda, Which Begins With Paying For A Diagnosis (2nd Opinion) From An Authorized honda Dealer. They “warned” Me That They Cannot Consider Helping Me Unless The Dealer Concludes There Is A Clear Manufacturer’s Defect. *jb

Stopped At A Stoplight Went To Take Off And Vehicle Shifted Oddly, Went About 500 Yards Stopped Shut Truck Off And Out Poured The Milky Transmission Fluid. Added Transmission Fluid To Get It Home And You Could Follow The Trail The Entire Way (approximately 1 Mile) And Empty Again (we Filled It). Opened The Overflow Antifreeze/coolant And The Same Strawberry Milky Fluid Was In There Completely Full! Also Opened The Radiator To Find It Completely Full Of The Same Stuff. I Have Read Many Accounts Of The Same Thing Happening While Driving At High Speeds, Thank God I Wasn’t, I Had My Entire Family In The Truck! It Would Be Nice For honda To Do Something About This!!! Going To A Mechanic Today, Will More Than Likely Be Making A Phone Call To honda Once The Verdict Is In! *tr

The A/c Condenser Fan Get Loose And Its Blade Were Moving Unporoperly Making A Large Hole In The Radiator. Suddenly The Rdaiator Lost All Water Causing That Engine Motor Brake The Seals, Piston And Other Parts Because The High Temperature. Since The Water Leaking Was Fast, The Temperature Sensor That Shows High Temperature At Dash Control Panel Eas Not Catched Until The Big Damage Of The Engine Happened. The Mechanic Technician States That Fail Of Thhis Fan Is Common On honda Vehicle. The Big Damage To May Parts Of Engine Happened Because Such A/c Condenser Fan Failed Without Any Advise And Is Common In honda, But No Recall Or Warning Ahe Been Notified By honda Dealers Or Factory.

We Purchased Our 2006 ridgeline Back In 2009 With Approx 46k Miles On It. At That Time, We Purchased The Hac (honda Auto Care) Warr & Cont To Drive For Yrs With Limited Problems Concerning The Veh. Around 82k On The ridgeline (2 Yrs Ago), I Had A Problem With The Vehicle That Prompted Me To Take The Vehicle Into The Dealer. They Advised Me That It Would Be Cov Under The Warranty, But The Warranty Was Exp In 2 Weeks (2 Weeks, But What About The 7 Yrs And 100k)?. I Inquired On The Terms & Explained That Was Not How It Was Positioned To Me. Roughly 2100.00 For A Little Over 2 1/2 Yrs Is Not What I Thought I Was Buying. Knowing That The Warranty Was Expiring, I Immediately Scheduled An Appt For The Following Weekend To Have Them Review The Entire Vehicle Top To Bottom (nothing Discovered At That Time). Where The Problem Creates: Last Wkd, Hit 101k & The Check Engine Light Appears W/ The Vtm-4 Light. I Know There Are Usual Codes For Reg Maint, But Seeing How I Have Had Vehicles Trigger Lights At 100k For Regular Servicing That Was Outside Of The Manual, I Then Contacted My Service Ctr To Inquire. He Reviewed The 105k Service With Me & Started He Would Get Back To Me On Any Codes. Later That Day I Received A Call Stating That The #4 Cylinder Was Misfiring & The Plug On #4 Was Caked With Baked On Oil. He Recommended Changing The Plugs First Before Going Into The Rest Of The 105k Service. 2 Days Later, The Chk Engine Light Starts Blinking & Vtm-4 Light Is On Again. He Later Calls Me To State The Head May Have A Crack & Explains Poss Damage Or Stall. What If It Stalls On The Freeway? What If The Cat Clogs (another 600 By The Way) And My Car Just Stops While Driving Though A Intersection? I Read Several Complaints About This Happening & Am Shocked honda Doesnt Respond To Any. I Cant Pay 3k – Called Dealer & Opened Case With honda Main Csr# 800-999-1009-no Response

    The transmission cooler line separated from the radiator. Upon noticing the trans slipping I pulled over and shut down the engine. Had the car towed to my home. I assumed it was a cooler line because of where the oil was dripping. I replaced the radiator and transmission fluid and got the 2006 Ridgeline back on the road.
    I spent a good part of my life repairing automobiles and have never seen anything like this. It is my understanding that Honda disavows all culpability for this design flaw and defect.
    When my Toyota Tacoma had a rusted chassis they reimbursed me 1.5 times the book value of the vehicle. Needless to say I have no faith in Honda and will trade the Ridgeline for a Tacoma. The Ridgeline has some good features and a nice ride, but the negatives outweigh the positives. This experience has left me with a bitter taste. I will never buy anything with the name Honda on it again.

    Cold morning 2/15/16 started my 2006 Honda Ridgeline sounded like a 5 gallon of water was spilled on the garage floor. All transmission fluid and antifreeze was on the floor. Towed back to the Honda dealer $1500.00 later is back

    Funny part was just spent $2800.00 in maintence timing belt, water pump, spark plugs, bushings. Less than a 1,000 miles and then this happened.

    Have a 2006 Honda Ridgeline that had a antifreeze odor and was consistently down a couple quarts between oil changes but no visible leaks. Brought it to dealer to have a look and they said the radiator was leaking… $1000 later i have a new radiator in it… and it is still a couple quarts low every oil change.

    6 months goes by and now the transmission starts to “slip” on starts. Drove it home nursing it along. Noticed a significant puddle of ATF form underneath. Check transmission, empty. WTF ? No warning light that transmission is low on fluid ( let alone empty ) ? No input shaft speed error ? ( had to change that sensor before so I know the computer knows when the engine turns and the tranny does not )

    Got under the car today… and pulled all the guards off and found the dealer kindly did not replace any lines or hoses to the trans coolers and they are all rusted and leaking. Why didn’t Honda make these lines of stainless ? Why would they not make a pressure sensor that would detect a loss of fluid in the trans ? Why does my dealer suck so much ? BTW… they are Metro Honda of Johnston, RI. Originally bought the car their as well as a CRV.

    Hoping the transmission is OK… I did fill it up and took it for a short drive and everything seemed fine.

    I have a 2006 Honda Ridgeline truck strawberry looking fluid came out of the fill cap lost all transmission fluid for no apparent reason looked into it found thousands of people with the same problems. Like to know if there are any recalls or compensation for this if so please let me know as soon as possible thank you. ( pretty upset this is the first one ever owned really liked this truck ).

    My 2005 pilot just blew out the drivers side trans cooler fitting, lucky the fluids did not mix. Replaced the radiator. Unscrewed the passenger side fitting and it was badly corroded between the washer and the threads of the aluminum fitting and the radiator. Also the threads of the fitting bearly caught the radiator threads. Bad design.

    2006 Honda Ridgeline, RTL, 182k miles, all recommended maintenance performed according to mfg maintenance schedule.

    Traveling 60mph, engine began to rev and then transmission disengaged and I coasted to the side of the road, fortunately there was a space to pull over safely. Same “strawberry milkshake” fluid gushed out onto the pavement. Towed to local mechanic (no Honda dealer near) they informed me there was a failure in the radiator and the transmission and coolant had mixed thoroughly both in the transmission and engine causing potentially irreparable damage. $1200, a new radiator, and ten transmission flushes later the truck was driveable again but isn’t shifting smoothly and there is an audible “clunk” when shifted between Drive / Reverse / Park doesn’t matter what order you shift in.
    Now a few weeks later the A/T Temp light has come on, ambient temp is 64F according to the in-dash display. Parked again on the side of the road. Very disappointed in Honda.Will probably never buy another.
