Right rear tire consistently lost 5 to 10 lbs. Pressure every two to three days, believed to be temperature change related, perhaps slow leak. Tires had approximate 20,000 miles left on them, but grew tired of the constant problem. On 09/21/2013 replaced both rear tires with new tires, problem persisted. On 09/28/2013 had dealer replace with factory rim ($339.32) problem solved. On 02/15/2014 same problem front right, added air every two to three days for the past few weeks, and on 03/18/2014 left front began same issue. Now forced to replace both front rims, they will not be factory replacements.

The contact owns a 2010 Chevrolet Malibu. The contact stated that she believed there was a nail in the tire due to the manner in which the vehicle was operating. The vehicle was taken to the dealer where it was advised that the tire was cracking from two areas at the wheel rim. The manufacture was made aware of the failure. The approximate failure mileage was 66,000.

We had to continually add air to one tire. Thinking we a had a nail, we took it to a tire shop. The rim was defective. That was when the car had 41,564 miles. We replaced it. Another rim went bad after 50,688 miles. Rims should not go bad. There must be a defect in the fabrication of the rims and Malibu owners are paying for it.

All four tires are losing air and have put air in 3 times. Have been told the rims are cracked and that this is a common problem with this car. Safety is of concern and it will cost $600 - $700 to fix. For what information I have GM is not doing a thing about it. I will not buy a GM car again if they do not resolve this issue.

It has been brought to my attention that I have 3 areas in my rim to be crack along the crease of a 5 star rim. I was informed by a couple of experts that these type of rims has been causing alot of owner difficulties. I do not believe we should be held responsible for a manufacturing defect, especially when it is clear that there was not any negligence on the part of the owner. It is obvious that I am not the only that has had this problem and would like to have this investigated for a recall..at this time I am refusing to pay for the rim, because no one has given me a "make since" explanation as to the blame.. I have even went as far a filing a claim with General Motors to have them shuffle me back and forth between the dealership and their (GM) specialist. Something need to give. I feel our safety in involved at this point. Had I not had it check and continued with the fix a flat formula and airing up the tire, who knows what could have happened to me and my family.. please look into this issue, not just for me, but for thousands od Malibu 2010 ls owners... thank you so much for you immediate attention and concern in regards to this issue in advance.

We have a 2010 Malibu ltz. One of the tires kept going flat. Took the car into the tire shop and the worker found a crack in the rim that could not be fixed. The entire rim had to be replaced at a cost of $200. This seems to be a common problem with these rims.

This is the second one to be replace. I thought the first one I replaced was an isolated case. I was on my way back from a funeral and stop at a dealers because the tire pressure was low. I know I needed some tries. I put on two tires and why the rim was off, they notice that it was bent. I had a problem last year with a rim that the dealer found a crack in it. Another customer had her Malibu in for service and they found out the her rim was bent also. On the internet, I noticed that this is not isolated as I thought it was. A crack or bent rim could cause a tire failure and may injure or kill someone. GM warranty doesn't cover this anymore. Oh I brought this car new.
