The 2016 BMW 3 Series Gran Turismo (F34) is a niche variant of BMW's popular 3 Series, offering a blend of performance, luxury, and added practicality. The F34 features a sleek fastback design, a longer wheelbase, and a higher driving position than the standard 3 Series sedan, giving drivers more room for passengers and cargo while maintaining the sporty characteristics for which BMW is known. However, as with any used car, it’s important to understand the common problems that may arise over time.
In this article, we’ll delve into the most frequent issues associated with the 2016 BMW 3 Series Gran Turismo, provide advice on what to look for when purchasing one, and discuss the costs of ownership.
Introduction: The Unique Appeal of the 2016 BMW 3 Series Gran Turismo
The 2016 BMW 3 Series Gran Turismo was created for buyers who needed more space than the standard sedan could provide but didn’t want to move up to a full SUV or larger vehicle. With its longer wheelbase, larger cargo area, and distinctive fastback styling, the F34 offers a unique mix of comfort and versatility. Available in both 328i (with a 2.0L turbocharged four-cylinder) and 335i (with a 3.0L turbocharged inline-six) variants, the 3 Series GT is praised for its smooth performance, luxurious interior, and advanced features.
However, owning a luxury German car also comes with its fair share of potential issues. Let’s take a closer look at the most common problems reported by owners of the 2016 BMW 3 Series Gran Turismo.
Common Problems with the 2016 BMW 3 Series Gran Turismo (F34)
1. N20 and B48 Engine Timing Chain Issues (328i Models)
The 2016 328i Gran Turismo is powered by either the older N20 2.0L turbocharged engine or the newer B48 2.0L turbocharged engine, depending on the production date. While the B48 engine addressed many of the reliability concerns of the N20, some 328i models equipped with the N20 engine may still suffer from timing chain tensioner and guide failures.
The N20 engine’s timing chain can stretch or wear prematurely, leading to a variety of engine issues, including:
- Engine rattling or ticking sounds at idle, particularly when cold.
- Illuminated check engine light due to timing misalignment.
- Engine stalling or misfiring under load.
The timing chain issue can result in catastrophic engine failure if left unaddressed. BMW revised the timing chain design in later production runs, but if you’re considering a 328i, it’s critical to verify whether the timing chain has been replaced or inspected as part of its service history.
2. ZF 8-Speed Automatic Transmission Issues
The ZF 8-speed automatic transmission used in the 2016 BMW 3 Series GT is generally praised for its smoothness and quick shifts, but some owners have reported transmission-related problems as the car ages. These issues typically present themselves as:
- Rough or jerky shifts, especially during low-speed driving or when coming to a stop.
- Delayed engagement when shifting from park to drive or reverse.
- Transmission slipping, where the car struggles to accelerate smoothly.
Most of these issues are related to transmission fluid degradation or software calibration. BMW doesn’t list transmission fluid changes in its standard maintenance schedule, but many experts recommend changing the fluid every 60,000-80,000 miles to maintain optimal performance.
3. Electric Water Pump Failure
Like many BMW models, the 2016 3 Series Gran Turismo is equipped with an electric water pump, which is prone to premature failure. The water pump is responsible for maintaining proper engine cooling, and when it fails, it can lead to overheating and potential engine damage. Common symptoms include:
- Sudden engine overheating, often accompanied by a warning light.
- Coolant leaks near the front of the engine.
- Unusual whining or buzzing noise from the engine bay.
Because water pump failure can lead to significant engine damage, it’s important to keep an eye on your coolant levels and have the water pump replaced if any symptoms arise.
4. Oil Leaks from Valve Cover and Oil Filter Housing Gaskets
Oil leaks are a common problem with BMW engines, and the 2016 3 Series GT is no exception. The valve cover gasket and oil filter housing gasket are prone to leaks as the rubber gaskets degrade over time due to heat and pressure. Signs of oil leaks include:
- Burning oil smell after driving, especially near the engine bay.
- Oil stains under the vehicle after it’s been parked.
- Low oil levels between oil changes.
While not an immediate threat to the engine, oil leaks should be addressed promptly to avoid potential engine damage or oil contamination in other components.
5. Suspension Wear
The suspension system on the 2016 3 Series Gran Turismo provides a smooth ride, but some owners report premature wear of key components, particularly the control arms and bushings. Symptoms of worn suspension components include:
- Clunking or rattling noises when going over bumps or rough roads.
- Unstable or bouncy ride quality.
- Uneven tire wear, indicating alignment or suspension problems.
While replacing worn suspension components is a routine repair for most vehicles, it’s important to check the condition of the suspension, especially on higher-mileage examples.
6. iDrive Infotainment System Glitches
The 2016 BMW 3 Series GT comes with BMW’s iDrive infotainment system, which controls everything from navigation to climate settings. However, some owners have reported issues with the iDrive system, including:
- Freezing or lagging screens, particularly when using navigation or multimedia functions.
- Bluetooth connectivity problems, where phones struggle to pair or drop connections frequently.
- Random system reboots, where the iDrive system shuts down and restarts unexpectedly.
BMW has released various software updates to address these issues, but in some cases, the head unit or control module may need to be replaced.
What to Look For When Buying a 2016 BMW 3 Series Gran Turismo
If you’re considering purchasing a used 2016 BMW 3 Series Gran Turismo, it’s essential to do your due diligence to avoid potential pitfalls. Here are some tips on what to inspect before making a purchase:
- Service History: A full service history is crucial. Check if the timing chain (for N20 engines), water pump, and oil leaks have been addressed. BMW recommends a strict service schedule, and a well-maintained vehicle is less likely to have costly issues down the line.
- Transmission Performance: During the test drive, pay attention to how the transmission shifts. Look for smooth, seamless shifts and ensure there’s no hesitation or jerking when changing gears.
- Check for Leaks: Inspect the engine bay and undercarriage for any signs of oil or coolant leaks. These are common issues that can become expensive if left unattended.
- Suspension Wear: Listen for any unusual sounds during the test drive, especially when driving over bumps. A clunking sound could indicate worn suspension components, which might require replacement.
How Expensive is It to Own a 2016 BMW 3 Series Gran Turismo?
Owning a 2016 BMW 3 Series Gran Turismo can be more expensive than owning a mainstream vehicle, largely due to the cost of maintenance, repairs, and premium fuel. Here are some ownership costs to consider:
- Maintenance Costs: Routine maintenance, such as oil changes, brake service, and tire rotations, can be pricier than for non-luxury cars. Expect to pay more for parts and labor due to BMW’s premium branding and the complexity of its engineering.
- Fuel Efficiency: The 3 Series GT offers decent fuel efficiency for a luxury vehicle, but both the N20 and N55 engines require premium gasoline, which increases fuel costs.
- Insurance: Insurance premiums for the 3 Series GT tend to be higher than average due to its luxury status and the cost of repairs.
- Depreciation: BMWs are known for higher depreciation compared to some other luxury brands, so keep this in mind if you're planning to sell the vehicle in the future.
Conclusion
The 2016 BMW 3 Series Gran Turismo (F34) is an appealing option for drivers who want the sporty performance of a BMW with the added practicality of a larger cargo area and more rear legroom. However, as with any luxury vehicle, it comes with its share of common problems. Issues like timing chain failure (in N20-equipped models), electric water pump malfunction, oil leaks, and transmission troubles can lead to expensive repairs if not addressed promptly.
If you’re looking to buy a used 2016 3 Series GT, it’s essential to check the service history for major repairs and ensure the vehicle has been well-maintained. While ownership costs can be higher than average, careful maintenance can help ensure a reliable and enjoyable driving experience.
