OVER THE PAST 20 YEARS, I HAVE OWNED 6 CARS (5 CADILLACS AND 1 MERCURY) EQUIPPED WITH MICHELIN TIRES. OF THESE 24 TIRES, I EXPERIENCED TREAD SEPARATION FAILURE ON 18 OF THE TIRES AND 1 SIDEWALL FAILURE AT 13000 MILES. TWO TIRES, I REMOVED AT 25000 MILES TO AVOID PROBLEMS AS I WAS PLANNING A LONG TRIP. THREE OF THE TIRES ARE STILL ON ONE CAR WITH ABOUT 13000 MILES ON THOSE TIRES. THE STANDARD SIZE FOR THE CADILLAC IS 215/65-16. MICHELIN ONLY RECOMMENDS THAT I SPEAK WITH THEIR DEALER. THE DEALER SAID HE COULD NOT ADJUST FOR THE TIRES. NEEDLESS TO SAY I DID NOT REPLACE THE FAILED TIRES WITH MICHELIN TIRES. I EXPERIENCED AN UNREASONABLE TREAD SEPARATION FAILURE RATE WITH MICHELIN TIRES (TIME WILL TELL FOR THE REMAINING 3 TIRES). THIS INDICATES A SYSTEMIC PROBLEM WITH THE MICHELIN DESIGN/MANUFACTURING. I DID A LITTLE RESEARCH ON THE SUBJECT OF TREAD SEPARATION FAILURES AND THE RESULTING PROBLEMS AND FOUND THAT THERE ARE SOME DEATHS ATTRIBUTABLE TO TREAD SEPARATION FAILURES. BECAUSE OF THIS AND THE EXTREMELY HIGH FAILURE RATE, I FEEL THAT THE MICHELIN RADIAL TIRES PRESENT A SERIOUS SAFETY HAZARD. I RECOMMEND THE NHTSA INVESTIGATE THIS PROBLEM. NOTE: I READ THAT TIRES MANUFACTURED IN EUROPE DO NOT HAVE THIS PROBLEM DUE TO A DIFFERENT DESIGN/MANUFACTURING PROCESS. IF THIS IS SO, THE US SHOULD MANDATE THE EUROPEAN DESIGN FOR US MANUFACTURED TIRES. I HAVE SPECIALIZED EDUCATION IN THE AUTOMOTIVE INDUSTRY THROUGH THE GENERAL MOTORS INSTITUTE AND 6 YEARS EXPERIENCE MANUFACTURING AUTOMOBILES. THE APPROXIMATE INCIDENT DATE IS FOR THE LATEST INCIDENT ON THE 13000 MILE TIRE. BEFORE THAT, I EXPERIENCED 2 TIRE FAILURES AROUND THE FIRST OF JUNE. *TR

IN FEB., 2007, MY MOTHER-IN-LAW BOUGHT A SET (4) OF MICHELIN SYMMETRY TIRES FOR HER MERCURY MARQUIS. WITHIN TWO MONTHS, ONE HAD A SIDEWALL BLOW OUT. THE DEALER TOLD HER THAT SHE MUST HAVE HIT SOMETHING, SO SHE BOUGHT A REPLACEMENT TIRE. LAST WEEK, MAY 30, 2008, WHILE DRIVING FROM MYRTLE BEACH TO ROCK HILL, SC, ANOTHER TIRE HAD A SIDEWALL BLOWOUT. AFTER WAITING ALMOST 2 HOURS IN 90 DEGREE HEAT, AAA ARRIVED AND CHANGED THE TIRE. SHE DROVE TO TWO TIRE STORES LOOKING FOR A REPLACEMENT. AFTER PURCHASING ONE AT THE LOCAL FORD DEALER, SHE STARTED HOME AGAIN. WITHIN 50 MILES, ANOTHER TIRE HAD A SIDEWALL BLOWOUT. THIS TIME WHILE WAITING FOR AAA, A SCHP OFFICER STOPPED AND AT LEAST PROVIDED SOME WATER. SHE DROVE HOME ON THE TEMPORARY REPLACEMENT TIRE. TODAY WE ARE GOING BACK TO THE DEALER THAT INSTALLED THE ORIGINAL TIRES. I SUSPECT THAT HER OPTIONS WILL BE TO EITHER PURCHASE ANOTHER MICHELIN SYMMETRY, OR AN ENTIRE REPLACEMENT SET. ON HER LIMITED INCOME, SHE'LL PROBABLY JUST BUT THE MICHELIN. HER DAUGHTER AND I ARE CONCERNED WITH HER DRIVING ON LONG TRIPS WITH THESE TIRES. I HAVE FOUND 23 PAGES OF COMPLAINTS ON MICHELIN TIRES ON THE CONSUMERAFFAIRS.COM WEBSITE. *TR

The Office of Defects Investigation (ODI) opened an investigation concerning the loss of headlights in model year (MY) 2003-2005 Ford Crown Victoria and Mercury Grand Marquis vehicles. The subject vehicles share the same architecture and major components.ODI has received 636 unique reports (for all submission dates) related to the alleged defect, with owners describing a loss of both low and/or high beam headlights occurring while driving.ODI identified 4 Vehicle Owner Questionnaire ( VOQ) reports alleging minor crash or loss of control incidents due to headlight failures.Drivers alleged running off of the road due to a lack of headlights and one driver reportedly struck a deer.No injuries were indicated in the VOQ crashes.In response to ODI's Information Request (IR) letter, Ford Motor Company (Ford) responded with 4173 unique reports related to the alleged problem.There were a total of 11 crashes reported within that group as well as one injury that occurred when the vehicle struck an unseen object on the side of the road when the headlights failed. Ford also submitted 49,843 warranty claims related to headlight failures.Most reports indicate that the headlights failed without warning leaving the driver with no forward lighting, however some noted the headlights flickered or dimmed prior to turning off.Consumers also noted they were able to hold the flash to pass lever on the steering column mounted stalk to activate the high beams however this is only effective as long as the lever is physically actuated.On December 21st, 2015 Ford notified ODI that it would conduct a safety recall (15V-861) to remedy headlight failures on (MY) 2003-2005 Ford Crown Victoria and Mercury Grand Marquis vehicles.According to Ford, the headlights of the vehicle are controlled by the Lighting Control Module (LCM) located in the engine compartment of the vehicle.The LCM uses an internal relay, mounted to a circuit board, to control power to the headlights. The headlight relay is soldered to the circuit board at six different terminals. The original equipment LCMs were manufactured in a manner that resulted in the solder joints fatiguing and/or cracking as a result of repeated thermal cycling and/or vibration, a defect condition. The condition could be exacerbated by manufacturing quality issues such as an insufficient amount of solder, effecting the continuity between the circuit board and the relay terminal, and resulting in loss of headlights while driving.Other lighting functions are unaffected by this condition.The LCM manufacturing processes were revised to address the defect condition and Ford has been conducting a warranty extension program to cover defective LCMs since late 2013.Under the recall Ford will replace any remaining defective LCMs in recalled vehicles with remedy LCMs once they become available.See NHTSA recall 15V-861 for further details on the safety recall.The recall action initiated by Ford addresses the safety risks of concern to ODI.Accordingly, the investigation is closed.The ODI reports cited above can be reviewed at SaferCar.gov under the identification (ODI) numbers found in the attached list.

PE14021 · Steering Column Shaft Obstruction

Opened Jul 7, 2014 · Closed Nov 21, 2014

Status: closed (inferred from source dates) · Engine And Engine Cooling:exhaust System; Steering

On July 7, 2014 the Office of Defects Investigation (ODI) opened a preliminary evaluation based on five complaints (VOQs) alleging incidents ofinterference between dislodged exhaust manifold heat shields and the lower steering shaft/knuckle, including one alleging the interference resulted in a crash on a highway entrance ramp. Since opening this investigation, ODI has received four additional owner complaints.One indicated that the shield was removed before binding could occur.The other three occurred at low speed and produced some momentary steering binding that was overcome by the driver when additional steering effort was applied.Once the shield was repaired or removed, the steering returned to normal.The single incident ODI identified as a possible crash (VOQ No. 10578715) related to this condition could not be verified and the description of the crash in the complaint was not supported by the police accident report.No additional crash allegations have been identified related to the alleged defect condition.Information provided by Ford in its September 10, 2014 response to ODI's information request letter identified 10 additional incidents resulting in a low rate of 1.6 incidents per 100,000 vehicles sold in vehicles ranging from 7 to 11 years in service.Six of these incidents were reported by a single source, a state police fleet that corrected the problems in March 2011 and has not reported any additional failures since.Ford also reported 5 warranty claims, but these incidents occurred at very low mileages and appeared to be caused by loose or missing heat shield attachment hardware rather than the corrosion condition that was the cause of the more recent incidents and the focus of this investigation.This investigation is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency will continue to monitor complaints and other information relating to the alleged defect in the subject vehicles and take further action in the future if warranted.The following VOQs are associated with this investigation:10643753, 10615584, 10611362, 10610451, 10578715, 10479681, 10471833, 10317493.
