TOP MAINTENANCE ISSUES WITH THE BMW 4-SERIES, 5-SERIES AND 6-SERIES

BMW Series

When considering ownership of a BMW, 3 primary options present. Sporty performance (compact/coupe), Luxury performance (sedan) or Practical performance (crossover), all with emphasis on “performance”. Previously, we discussed the potential BMW repair issues of the 1, 2 or 3-Series website, all offering the smaller, “sportier” versions of the brand. In this segment, we want to highlight the possible hurdles presented in the slightly larger, “luxury” models. Again, not all cars are alike and these issues are not present in every BMW. Regardless of the issues your car might present, you can trust Auto Works of Brandon as your BMW repair shop in Tampa. This information is meant to provide an outline to aid in your research as you seek to make an informed decision.

4-Series

  • High-pressure Fuel Pump in the Turbocharged Engine, characterized by stalling, rough idle, rough running and long crank times. Naturally aspirated engines seem to have fewer issues and provide more reliability.
  • VANOS sensors get dirty and clogged, potentially causing the car to go into a “limp-mode”.
  • Electrical / Battery issues, often caused by corrosion of the cable connectors.
  • Minor annoyances like rattles, clinks and vibrations.

5-Series

Around since 1972 and having seen 6 generations of production, the 5-series is the brand’s second best-selling model. It’s won many awards over the last 4 decades, including “Highest Ranked Premium Car” by J.D. Power’s 2015 U.S. Initial Quality Study, but there are still cautionary tales to be told when a car has been around for 40+ years. Here are the lowlights:

  • Electrical System issues
  • Engine Cooling Systems (Coolant leaks, failed Water Pumps, etc)
  • Oil Leaks, Fuel Pumps and Fuel Injector failure
  • Crankcase Ventilation System (CCV) issues (Cracked Hoses, Vacuum Leaks, Intake Boots, etc)

Again, with more data on the 5-Series, a more comprehensive picture develops and trends appear. It is worth mentioning that the reliability increases profoundly in 2011 models and later. Courtesy of True Delta.com, here is a graph to illustrate the Repair Problems and Repair Cost breakdown.

6-Series

First on scene from 1976-1989, this touring line was out of production for 14 years before re-entering the market in 2003 to fill the space left by the exiting 8-Series. Based loosely on the 5-Series saloon/touring model, the 6-Series offers a coupe/cabriolet with more emphasis on performance instead of practicality, as it is more closely compared to the 7-Series models in price. In terms of reliability, there is still a bit of ground to cover as there is a fairly well known issue with this line and it seems to run across all of the offered models. Simply put, the Electrical Systems are faulty. The problems include:

  • Electrical Sensors (Engine sensors, temp sensors, convertible roof sensors)
  • Entertainment Systems
  • Bluetooth / Phone, etc.
