BMW 5 Series Trouble Spots

Consumer Guide's® Auto Editors have scoured repair bulletins and questioned mechanics to search for commonly occurring problems for the BMW 5 series. Their findings are listed below and the need for BMW 5 series extended auto warranties is evident. While BMW makes a wonderful automobile, we were startled at the number of service visits drivers needed during their ownership.

BMW 5 Series extended auto warranties will protect against BMW factory labor rate increases too. As many of us already know, BMW service facilities have the most expensive labor rate for shop mechanics. BMW parts prices are near the highest in the industry too. There is a price to pay for riding in style with an automobile like this!
