Selected complaints filed with NHTSA by 2003 Ford Mustang owners, lightly cleaned up (personal details are redacted by NHTSA).
The Belt Strap will get twists along the length. The Body Pillar clip refuses free movement. This is aggrevating for a Driver in the Seat. Driver in vain pushes Power Seat back to allow the Belt to clip into Latch at the Console. Reality. The car is 22-yrs old. Owner expects indifference by the local Ford shop. Both a neighbor & the Owner had a hard time about service. What does the Owner thinks a good solution? Late Model Restoration is this Model's best parts hope. A indy-body shop near the home of the car a repair alternative. Owner is [redacted] in a [redacted] & uses the Car as a Daily Driver. May be able to upload images of the car.
I recently purchased this vehicle and noticed the next day that the passenger seat belt will neither retract or extend to a usable length . Online I have noticed numerous similar complaints. My local dealer wants $287.00 plus labor of approximately 2 hours to repair and from what I'm seeing there is no guarantee it will be fixed.
All 4 seat belts have operational issues. Passenger seat belt fully extended and will not retract. Driver side semi functional will not retract fully. Both rear difficult to retract. Clear coat on front bumper and spoiler coming off in sheets.
Seat belts both sides never worked to this dayy. I took the car back to the dealer twice they never fixed the problem.the belt s will not retract into the holder belts lay down get stuck in door and dangle out side car
When the rear seat belt retracts, and it has a twist in the belt material (webbing), the retracting mechanism will lock preventing the belt from being pulled back out. This lock is similar to the locking which the retractor does, as it is designed to do, during rapid deceleration. The belt (webbing) "guide" allows the belt to retract with one or more twists in the webbing just as easily as it does when there is no twists. In other words, the "guide" doesn't prevent the belt from retracting when there is a twist in the webbing, and thus doesn't prevent the retractor lock up problem. The retractor locks with the belt in the fully retracted position (the webbing is fully wound up into the retractor). When this happens, this problem makes the seat belt unavailable for usage by the passenger (child) in that seat position. …
Passenger seat belt started sticking and being hard to pull out in 2005, I took it back to dealership they stated it was OK, I hardly used that passenger seatbelt because I usually drive alone. In 2009 it got stuck in the holder and I could not pull it out, at that point the Ford dealership wanted over $300.00 to replace their already defected seatbelt. I checked junkyards in three different states and all the 2003 Ford Mustang passenger seatbelts was broken. My headlight cover is made of some sort of substandard plastic that fogged up and made it difficult to see clearly and plus it causes my car to fails inspection. Ford dealership requested that I pay them over $600.00 to replace headlights with more detected headlight. I call Ford headquarter to no avail. …
As an overweight 6'9" citizen and phd scientist, I would like to know what safety tests are done for people that deviate from a normal size and weight. I understand that safety tests are done for children, but what about people that are very tall, or as it is an increasing problem in the us, people that are very obese? My seat belt touches my neck rather than going over my shoulder, potentially exposing me to neck injuries. The passenger airbags will impact my knees rather than my body, and there is no neck support from my headrest. I am quite concerned that I could be severely injured in an accident since vehicles are not properly tested to support tall and/or overweight individuals. Presumably the NHTSA and ntsb could be held liable for a lack of such testing were someone injured in an accident. …
Both the front seatbelts will not retract, without considerable effort. This results in driving with the belt very slack over the chest and lap. I'm very concerned that if I am involved in an accident, this slack will permit injury. I have looked over your database of customer complaints, and this exact defect has been documented time after time, with no accountability by Ford motor co.. I know your "standard boiler-plate response" is that Ford's number one concern is safety, but why do you continue to ignore this obvious, continuing defect, year after year? Is safety important, or not?
Passenger side front seat belt continually locks up. Seatbelt is completely inoperative right now and will not retract or come out. Asked Ford about the voluntary recall I had seen elsewhere and was told that there was none and parts were $300 to fix and two hours of labor to install and would carry a 12 month/12,000 mile warranty. Told them that seat belts were a safety issue that they needed to look at. Received a seatbelt violation ticket on the way home and since haven't driven the vehicle with a passenger.
