9 reportsCHECK ENGINE WRENCH CAME ON VEHICLE BEGAN TO LOOSE POWER. GAYLORD FORD FOUND NO RECALL BECAUSE THE CAR WAS BUILD AUGUST 2009 IN THE SAME PLANT AS OTHER VEHICLES WITH THE PROBLEM WITH THE THROTTLE SENSOR FOR POWERTRAIN. THE VEHICLE LOST POWER AND WOULD ONLY GO 30 MPH. CAR IS A 2010 MILAN HYBRID 133,000 MILES.

I HAVE BEEN ON THE PHONE WITH FORD. AN EXTREMELY MAD AND RUDE WOMAN DIDN'T OR COULDN'T ANSWER ANY QUESTIONS I HAD. SHE KEPT TELLING ME I GOT MY RECALL BE CAUSE THEY CHECKED MY COMPUTER SYSTEM BUT DIDN'T REPLACE THE RECALLED STEERING MODULE. THE WOMAN ALSO DIDN'T HANG UP SO I WAS UNABLE TO DO THE SURVEY AT THE END OF THE PHONE CALL. SOME PEOPLE ARE DISGUSTING THE WAY THEY TREAT OTHERS.
BRAKE WARNING LIGHT AND A MESSAGE ON THE DASH SAYING "CHECK BRAKE SYSTEM" INTERMITANTLY OCCUR. BRAKES SEEM TO WORK NORMALLY. RESTARTING THE CAR TEMPORARILY FIXES THE PROBLEM, ONLY TO OCCUR AGAIN IN SEVERAL MILES. THE PROBLEM OCCURS AT ANY TIME, STANDING OR IN MOTION.
WAS STOPPED AT A RED LIGHT, CAR HAD BEEN DRIVING FINE, BUT WHEN THE LIGHT TURNED GREEN AND I PROCEEDED MY CAR SUDDENLY HAD REDUCED POWER AND WOULD NOT DRIVE MORE THAN 40-45 MPH. NO LIGHTS OR ANYTHING CAME ON THE DASH THE FIRST TIME. THE SECOND TIME HOWEVER A YELLOW/ORANGE WRENCH LIGHT APPEARED. I GOT HOME AND PARKED FOR THE REMA…

WAS STOPPED AT A RED LIGHT, CAR HAD BEEN DRIVING FINE, BUT WHEN THE LIGHT TURNED GREEN AND I PROCEEDED MY CAR SUDDENLY HAD REDUCED POWER AND WOULD NOT DRIVE MORE THAN 40-45 MPH. NO LIGHTS OR ANYTHING CAME ON THE DASH THE FIRST TIME. THE SECOND TIME HOWEVER A YELLOW/ORANGE WRENCH LIGHT APPEARED. I GOT HOME AND PARKED FOR THE REMAINDER OF THE DAY BUT THEN THE FOLLOWING DAY THE PROBLEM STILL PROCEEDED AND I THEN LET IT SIT ALL WEEKEND. THE FOLLOWING MONDAY I TURNED IT ON TO TAKE TO THE REPAIR SHOP AND THE CAR DROVE FINE THAT ENTIRE DAY. THE NEXT DAY, TUESDAY, WHILE DRIVING HOME FROM WORK IT HAPPENED AGAIN ONLY I COULDNT GO FASTER THAN 30MPH IN A 55 MPH ZONE. CAR WAS TAKEN BACK TO SHOP AND DIAGNOSED AS A FAILURE IN THE THROTTLE BODY. DURING THIS TIME OF REDUCED POWER FANS IN THE TRUNK SPACE GOT EXTREMELY LOUD AND BEGAN SUCKING IN AIR, AS IF TRYING TO COOL THE BATTERIES. NEEDLESS TO SAY FORD HAS BEEN NO HELP AND I CAN NOT GET TO WORK AS I CANNOT SAFELY DRIVE MY VEHICLE DUE TO THE LIMP HOME MODE ACTIVATING AND RANDOM TIMES. THE PRIOR INVESTIGATION INFURIATES ME TO SEE THEY EXTENDED A WATTANTY INSTEAD OF DOING RECALL BECAUSE NOW OWNERS LIKE MYSELF ARE STUCK NOT EVEN BEING ABLE TO GET TO THE DEALERSHIP BECAUSE THE CAR IS NOT SAFE TO OPERATE.
ON FRIDAY, DEC 13TH, I WAS DRIVING HOME IN CRUISE CONTROL AT 60 MPH. MY BLOOD PRESSURE DROPPED SUDDENLY AND I PASSED OUT AT THE WHEEL. I WOKE UP JUST IN TIME TO CRASH, NO TIME TO REACT. I IMPACTED, HEAD ON, A CREEK BANK AFTER JUMPING OVER THE CREEK. MY AIRBAGS DID NOT INFLATE AND I IMPACTED THE STEERING WHEEL SO HARD I BROKE…

ON FRIDAY, DEC 13TH, I WAS DRIVING HOME IN CRUISE CONTROL AT 60 MPH. MY BLOOD PRESSURE DROPPED SUDDENLY AND I PASSED OUT AT THE WHEEL. I WOKE UP JUST IN TIME TO CRASH, NO TIME TO REACT. I IMPACTED, HEAD ON, A CREEK BANK AFTER JUMPING OVER THE CREEK. MY AIRBAGS DID NOT INFLATE AND I IMPACTED THE STEERING WHEEL SO HARD I BROKE THE STEERING COLUMN OFF THE DASHBOARD. 3 DAYS IN THE HOSPITAL WITH A COMPRESSED CHEST, IMPAIRED BREATHING, AND MASSIVE BRUISES. I HAD A COLD AT THE TIME AND IT MADE RECOVERY SLOWER. *TR

WHILE DRIVING AND ATTEMPTING TOP ACCELERATE UP TO SPEED, THE VEHICLE BEGAN TO SLOW AND HESITATE. IT WOULD NOT PROPERLY ACCELERATE. AFTER GOING A SHORT DISTANCE AT REDUCED SPEED, THE VEHICLE BEGAN TO SHAKE AND HESITATE. I WAS ABLE TO MAKE IT HOME (LUCKILY NOT TOO FAR). THE WRENCH SYMBOL ON THE DASH ILLUMINATED DURING THIS EPISODE AS WHEEL. I CHECKED THEOWNERS MANUAL AND THEN CALLED MY LOCAL DEALER WHO RECOMMENDED THE CARE BE TOWED TO DEALER AND NOT DRIVEN. THIS WAS DONE THE NEXT DAYAND AFTER A FULL DAY OF CHECKING THE VEHICLE, THE DEALER ADVISED THEY HAD NO IDEA WHAT THE PROBLEMS WAS. THEY RELEASED THE CARE TO ME. THE NEXT WEEK THE SAME SITUATION HAPPENED SEVERAL MORE TIME AND FINALLY, WHILE ON THE WAY TO DEALER, IT HAPPENED AGAIN WITH THE SERVICE ENGINE LIGHT COMING ON AS WELL. THIS TIME THE DEALER IDENTIFIED THE PROBLEM AS THE THROTTLE BODY AND REPLACED IT AT A COST INEXCESS OF $500. *TR

2DP22005 · Pedestrian Alert Sounds
Opened Jan 27, 2023 · Closed Aug 7, 2023
Status: closed (inferred from source dates) · Electrical System:propulsion System
NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.
DP15001 · Loss Of Power Steering While Driving
Opened Apr 1, 2015 · Closed Jun 14, 2018
Status: closed (inferred from source dates) · Steering:electric Power Assist System
On May 27, 2014, amended June 2, 2014, Ford Motor Company (Ford) submitted a Defect Information Report (DIR) to NHTSA describing a safety defect that may result in a sudden loss of power steering assist while driving in approximately 746,067 model year (MY) 2008 through 2011 Ford Escape vehicles equipped with electric power assisted steering (NHTSA 14V-284, Ford 14S05). Ford's DIR described the defect condition as a poor signal to noise ratio [SNR] in the torque sensor within the Electric Power Assisted Steering (EPAS) system [which] does not allow the PSCM to determine the driver's steering input. When the system detects this fault condition, it transitions the EPAS system to the fail-safe/manual steering mode.Ford's DIR indicates that loss of power steering assist while driving would require higher steering effort at lower vehicle speeds, which may result in an increased risk of a crash.Ford's remedy instructs dealers to check the Power Steering Control Module (PSCM) for Diagnostic Trouble Codes (DTCs) to determine the proper repair procedure. If no DTCs are present, dealers are to update the PSCM and instrument cluster module software. The updated PSCM software changes the torque sensor fault strategy so that the SNR condition does not result in a loss of power steering assist while driving.In addition, audible and visual warnings are provided for torque sensor faults.If DTCs indicating faults in the torque sensor, PSCM or Power Steering Motor (motor) are present in the initial recall inspection, the dealer performs the following repairs: 1) replaces the torque sensor for torque sensor faults (DTC B2278); or 2) replaces the steering column for faults related to the PSCM (DTC B1342) or motor (DTC B2277).Continued in attachment pages
