“There is a recall on some of the make & models of my truck with different years but, my truck has been having the same issue & I believe that myself & my family may be at risk. The recall states that if the oil level in the ACS reservoir is below the minimum level, the oil may foam & leak out of the vent holes in the reservoir cap. The leaking of oil in the presence of ignition source can increase the risk of fire. I have been having to add two quarts of oil to my car every month for almost a year & there has been no oil in my driveway at all. …”
