The contact owns a 2007 Ford Mustang. While driving 15 mph the low tire pressure indicator illuminated on the instrument control panel. He then added air to the tire, but by the end of the day all of the air was released out of the tire. The vehicle was taken to a local repair facility. The mechanic replaced a defective valve stem. He then received a recall notice regarding the valve stems, but a technician stated that no repairs could be performed until the valve stems failed. The current mileage was 24,900. The failure mileage was 24,500.

My car is a 2007 Ford Mustang GT and since we purchased it in March 2007, we have had 3 separate issues with the valve stems. In the most recent incident, my son was driving the car and experienced a tire blowout while traveling at highway speeds. When we took the car to the dealer we were told that the problem again came from a cracked valve stem. Ford did replace the tire at no charge to us; however I still have concerns about the safety of the vehicle and the remaining valve stems.

I have a 2007 Ford Mustang GT premium convertible. I had taken two of my tires to ntb to have the tires replaced with oem tires. I noticed the valve stems cracked on the old tires, and asked to have them replaced. Upon driving the car the very next day, one of the new tires lost pressure and went flat on the highway. When I went to replace it with my spare, I noticed the valve stems were not replaced. I immediately called ntb, and they are going to replace the now bad tire with a replacement, and change both valves, which were never replaced. After I got home I noticed that the two original tires that were not replaced have cracked valves. I am going to have these replaced also. The original tires only have 12,000 miles on them.

I have a 2007 Ford Mustang that I have to constantly keep adding air to the tires. I thought I just ran something over, but I don't see anything and it seems to be a slow leak in all tires. I recently saw the investigation on the valve stems so I wanted to give my input that I think my car could possibly be affected by this. I called my dealer and said the valve stems could be replaced at my expense only at this time.

I read an article in the September 2008 consumers reports magazine which described a recall for manufacturer : tech international, NHTSA campaign id number : 08T018000, for defective tire valves. I had a problem with a defective tire valve recently on my 2007 Ford Mustang, and now wonder if Ford isn't using this same manufacturer of tire valves in their new cars. More details of my incident follow... 1) I was driving at approx. 55 mph on two lane road on a hot (90+) summer day (6/8/08). The low pressure warning light came on, and I pulled over asap to investigate. 2) the driver side rear tire was low. I pumped air into the tire, and noticed the valve stem was cracked at the base where it installs in the alloy rim. It would not hold pressure, so I installed the spare, and drove to a nearby sears to repair the valve stem. 3) I paid $26 for a "flat repair" - basically they replaced the tire valve. I do not have the old part. The good news is the tire pressure sensor technology saved me from having a high speed flat. I expected to find a nail in my tire, not a faulty valve stem. I have not contacted my local Ford dealer at this time. I purchased the car new from Ford in April 2007. It is a 2007 Ford Mustang V6, 4.0L SOHC, with approx. 10K miles. The tires are pirelli pzero nero P235/ mounted on alloy wheels.
