Traveling home from GA to NC, family trip on a Sunday afternoon. Dashboard light states tire problem. Stop vehicle to check, left front tire looking little low. Drove to nearby station, go to take valve cap off and cap/portion of stem shoot off into the parking lot and tire goes completely flat in seconds. Then had to call AAA for assist, buy and mount another tire as that we are over 100 miles from home. Back on the road again and not even 30 min later, ride feels odd, sensor goes off and before can pull over from the highway - rear drivers tire is flat with a broken stem.

Mind you the sensors, wheels/rims, tires are all in good shape. It's the damn valve stems over and over! At this point, it is late on a Sunday evening and we are not in such good shape with a response and availability of repair shops. After much stress, find a tire shop willing to stay open and help out. Another tire purchased, mounted, etc. Another fee...all the time having trouble getting the sensor light off the dashboard. In fact, the sensor light seems to never reset easily and have to make another trip to a dealership to have it handled. Which they charge me an additional $105 per sensor/tire to reset! This now costs approximately $400 for two tires - not mentioning time and gasoline spent trying to get help. Plus the risk to life having these dame valves blow apart repeatedly.

Traveling home from GA to NC, family trip on a Sunday afternoon. Two incidents with tire valves. Dashboard light states tire problem. Stop vehicle to check, left front tire looking little low.

OK -- 4th time now in 1 year. Sitting on front porch, talking on the phone -- hear a whoooshing/hissing sound. While the car was parked in the driveway, doing nothing...the valve stem broke near the cap. Now have to change the tire, go back to the tire dealership, have another valve/sensor put on, $160.00 and again. Tire shop can't seem to get the damn dashboard light off - although everything works. They again tell me to go to the dealership to have the dashlight reset 'for no charge...takes minute".

Well, now that the dealership I purchased from no longer has a Mitsubishi office (hmmm is there an underlying reason for that?) I have to go back to a different/further dealership, who now tells me "well....we don't usually do it for free and I don't know why you were told $50.00 at most...it will be $105.00 to reset the sensor/dashlight". OK, so another $140-160.00 for the 4th damn time in about a year's time just to replace the valve/sensor PER tire and/or tire costs in previous incidents...plus now another $100+ dollars to reset the computer/dashlight each damn time!? Hell, at this point I could've had new set of tires put on as well. Plus, the inconvenience of having to travel from shop to shop to keep replacing stems, etc. It is enough to say no more Mitsubishi's!

I have purchased from the now-shut-down dealership multiple times and this is my 3rd vehicle from them -- but have had too many problems with these stupid valves. All for crappy alloys! The safety issues alone for something like this is ridiculous ...going to lose my life over what 30 cents manufacturer savings, and then keep having to pay hundreds for new sensor/valve set-ups because it's the law. Plus, never going to know when this will happen again -- will I be so lucky to not die or be severely injured next time?

There should be a recall or a change in the specs to the valve stems -- they should replace them with another material entirely -- and they should pay! What a scam. Go back to the old tires/valves, and no damn computer dashboards -- even if the light goes on - if you're doing 70 mph on the road and the damn valve snaps you're still likely in an accident before you can pull over in time. I have been lucky to be in gas stations, in my driveway, or in slow traffic on the highway each time. When is my luck running out? When does big business really care about safety and fix the problem of cheap materials - instead of telling me how I need an "idiot" light to go off first? I've had cars w/o computers and been just as safe, if not safer!

Driving to work, early morning, drizzling and cold. Tire pressure/dashboard light goes off. Pull over to a nearby station to check the pressure. Tires look good, start checking the readings...go to unscrew the valve stem cap to check the pressure - cap shoots off across the parking lot into the bushes and tire whoooooshes flat! Damn! Again - 3rd time in less than 6 months. Have to call in late to work.

Call AAA to assist. Damn spare is flat again, too -- same problem -- suspected slow leak d/t cracked stem?? Don't have time to deal with that! Have regular spare tire now - since this just happened within 6 months prior and had to buy new tire/stem. AAA mounts it - mentions it is probably the alloy on the valve stem as that the tires all look good (again). Drive to tire shop - have sensor/valve stem replaced -- light won't go off dashboard despite multiple trips to shop - as that the "dealership apparently has special codes which sometimes this happens...they should assist w/o charge or problem".

Go to dealership as that the dealership purchased from is no longer and also received a recall letter about something else. Dealership happy to assist, but "should charge you about $50.00 to reset the dashboard for the sensor". Then present me with a check list of maintenance (already done in last 12-18 months) of things I need for a total of about $1800.00..."but, did the sensor for free this time...no known problems with sensors, except for vehicles in 2007 and prior...but also no "recalls" either...Oh well' hopefully this won't happen again". Yeah, right.

The 1st valve stem broke during the warranty period. The 2nd one broke 2000 miles after the warranty ended. The breakage ocurred both times while adding air and checking air pressure. Looks like the valve stems are made out of potmetal.

I have owned 29 cars in my lifetime and I never had this kind of a problem. I suspect that normal valve stems are made out of stainless steel.

Parts = $67.52 Labor = $106.60 Tax = $12.19 Total = $186.31 (Absolutely ridiculous for one valve stem).

I have become very hesitant about checking air pressure because if breakage ocurrs, the tire goes flat immediately. Then it's 30 miles to the dealership (If they are still open) on the emergency spare.
