The 2013 BMW 3 Series Gran Turismo (GT) was designed to offer a blend of BMW’s legendary driving dynamics with added versatility and practicality. This fastback-styled version of the popular 3 Series aimed to give owners more cargo space and a higher seating position without sacrificing the brand’s sporty appeal. However, as with any luxury vehicle, the 3 Series GT isn’t immune to issues that can crop up over time. Understanding the common problems associated with this model can help you better maintain your vehicle or make an informed decision if you’re considering buying one.
In this article, we’ll dive into the common problems of the 2013 BMW 3 Series Gran Turismo, give tips on what to look for when buying a used one, and discuss the costs involved with ownership.
Introduction: The BMW 3 Series Gran Turismo’s Unique Appeal
Launched as a niche model in BMW’s lineup, the 3 Series Gran Turismo combines elements of a sedan, hatchback, and crossover. It’s built on a longer wheelbase than the standard 3 Series sedan, providing extra rear legroom and cargo capacity. The car’s higher roofline and fastback design appeal to those who need more space without moving to a full-sized SUV or wagon.
Powered by turbocharged four- and six-cylinder engines, the 3 Series GT offers impressive performance, with the added practicality of a hatch-style rear door and foldable rear seats. While this combination is attractive, the 2013 model has its fair share of problems that have been reported over the years.
Common Problems with the 2013 BMW 3 Series Gran Turismo
1. N20 Engine Timing Chain Issues (for 320i and 328i Models)
One of the most significant issues affecting 2013 3 Series GT models equipped with the N20 2.0L turbocharged engine (found in the 320i and 328i trims) is timing chain failure. The timing chain plays a crucial role in synchronizing the engine’s valves and pistons, and when it fails, it can lead to catastrophic engine damage.
In many cases, premature wear of the timing chain tensioner or guides has led to noisy operation and eventual chain failure. Symptoms to watch for include:
- A rattling or ticking noise from the engine, particularly at startup or idle
- Engine misfires or rough running
- Illuminated "check engine" light
BMW issued a service bulletin for this issue, but it's important to verify if the previous owner has had the chain replaced or inspected, as this can prevent a costly repair.
2. Electric Water Pump Failures (N20 and N55 Engines)
Both the N20 (four-cylinder) and N55 (six-cylinder) engines in the 3 Series GT use an electric water pump, which is prone to failure over time. The water pump’s job is to regulate the flow of coolant through the engine to prevent overheating. Unfortunately, the electric water pump in these engines tends to fail earlier than expected, leading to overheating problems.
Signs of a failing water pump include:
- Sudden engine overheating
- A warning message about coolant temperature
- Coolant leaks near the front of the engine
Replacing an electric water pump can be expensive, and because this is a common issue, it’s wise to ask for service records when buying a used model to ensure the water pump has been replaced recently.
3. High-Pressure Fuel Pump (HPFP) Issues
BMW’s turbocharged engines, particularly the N55 3.0L six-cylinder, are known for high-pressure fuel pump (HPFP) failures. The HPFP is responsible for delivering fuel at high pressure to the fuel injectors in direct-injection engines. When it fails, the car may experience:
- Rough idling or engine stalling
- Difficulty starting the engine
- "Check engine" light or engine malfunction warning
BMW has made improvements to the HPFP over time, but some 2013 models may still experience issues. If the HPFP hasn’t been replaced, this is a potential repair to keep in mind.
4. Oil Leaks from Valve Cover and Oil Filter Housing Gaskets
As with many BMWs of this era, oil leaks are a common issue, particularly around the valve cover gasket and oil filter housing gasket. These leaks are more of a nuisance than a severe mechanical problem, but they can lead to oil drips on the driveway and, in extreme cases, cause oil to enter the cooling system or engine bay.
Symptoms of oil leaks include:
- Visible oil stains under the vehicle
- A burning oil smell after driving
- Low oil levels between oil changes
These gaskets are made of rubber, which tends to deteriorate with age and heat. Replacing the valve cover gasket or oil filter housing gasket is a relatively routine repair for BMWs and should be done promptly to avoid larger problems down the road.
5. ZF 8-Speed Automatic Transmission Issues
The ZF 8-speed automatic transmission, used in most 2013 BMW 3 Series GT models, is generally reliable, but some owners have reported transmission shifting issues over time. Complaints include:
- Rough or jerky shifting, especially at low speeds
- Hesitation when accelerating from a stop
- Transmission slipping or not engaging properly
These issues are sometimes related to software problems, and a transmission reprogramming may resolve them. However, in more severe cases, mechanical components within the transmission may need attention, which can be costly. Regular transmission fluid changes, even if not specified in the official maintenance schedule, can help prolong the life of the transmission.
6. Sunroof and Panoramic Roof Problems
The 2013 BMW 3 Series GT often comes with a panoramic sunroof, which adds to the open feel of the cabin. However, this feature is prone to malfunctions. Common complaints include:
- Leaking sunroof: Water can seep into the cabin due to clogged or misaligned sunroof drains.
- Sunroof not closing properly: The panoramic roof may not seal correctly, leading to wind noise or potential leaks.
Regular maintenance of the sunroof’s drainage channels is crucial to avoid water damage to the interior. Sunroof motor failure can also occur, and replacing the motor or tracks can be costly.
7. Electrical and iDrive System Glitches
The iDrive infotainment system, while generally praised for its usability, has been reported to suffer from glitches. Common issues include:
- Freezing or unresponsive screen: The infotainment screen may lock up or stop responding to inputs.
- Bluetooth connectivity issues: Problems pairing phones or maintaining stable connections have been noted.
- Navigation errors: Some owners report inaccurate navigation or slow system response.
Software updates can often resolve iDrive issues, but more serious problems with the control unit may require replacement.
What to Look For When Buying a 2013 BMW 3 Series Gran Turismo
If you’re considering buying a 2013 BMW 3 Series GT, there are a few critical areas to inspect to avoid costly repairs down the road:
- Service Records: Make sure the vehicle has a comprehensive service history, especially regarding the timing chain replacement (for N20 engines), water pump, and high-pressure fuel pump.
- Transmission Performance: During the test drive, pay close attention to how the transmission shifts. Look for any signs of jerking or delayed engagement.
- Sunroof Functionality: Check the panoramic sunroof for proper operation. Ensure that it closes and seals correctly and inspect for any signs of water leakage.
- Engine Condition: Listen for unusual engine noises, particularly rattling or ticking, which could indicate timing chain or engine component wear.
How Expensive is It to Own a 2013 BMW 3 Series Gran Turismo?
The BMW 3 Series GT, like most luxury vehicles, comes with higher-than-average ownership costs. Here are some of the key factors:
- Maintenance and Repairs: Routine maintenance, such as oil changes, brake replacements, and fluid changes, is essential to keep the vehicle running smoothly. However, repairs for common problems like timing chain replacements or water pump failures can be expensive, ranging from $1,000 to $3,000 depending on the issue.
- Fuel Economy: The 3 Series GT’s fuel economy is decent for its class, but the turbocharged engines require premium fuel, which can increase running costs.
- Insurance: Insurance premiums for the 3 Series GT tend to be higher than average due to the vehicle’s luxury status and the cost of repairs.
- Depreciation: While BMWs hold their value better than many luxury vehicles, expect significant depreciation, especially as the car approaches 10 years old.
Conclusion
The 2013 BMW 3 Series Gran Turismo offers a unique mix of performance, luxury, and practicality, making it a popular choice for those who want a spacious yet sporty vehicle. However, potential buyers should be aware of common problems such as timing chain issues, water pump failures, and electrical glitches. Regular maintenance and addressing issues early can help prevent major repairs and keep the car running smoothly.
If you’re looking to buy a used 2013 BMW 3 Series GT, make sure to check the vehicle’s service history and have it thoroughly inspected by a mechanic familiar with BMWs. Although ownership costs can be high, proper care and attention can make this vehicle a rewarding long-term investment.
