When Did The Model S Come Out

So, you're having an issue with your Model S, and you're trying to figure out if it's a common problem for your car's year? A good first step is knowing when the Model S actually came out. While that might seem simple, understanding the production timeline can help you narrow down potential causes and identify relevant service bulletins.

When Did The Model S Come Out, and Why Does It Matter?

The Tesla Model S officially launched in June 2012. This date is crucial because different model years have different hardware, software, and even manufacturing processes. Knowing your car's build date (often found on the driver's side door jamb) helps you pinpoint whether a particular issue is a widespread problem for cars of that era, or something more unique to your specific vehicle. This knowledge empowers you to research effectively, communicate clearly with your service technician, and potentially save time and money on repairs.

For example, early Model S vehicles (2012-2014) had different battery chemistries and charging system components than later models. Identifying your car as an early build can help you immediately focus on the common issues from the time period, such as MCU1 failures, potential 12v battery problems, and certain types of drive unit issues that were later addressed in newer revisions.

Common Symptoms Indicating Problems in Early Model S Vehicles

The symptoms you experience can offer clues about the underlying problem. Keep an eye out for the following:

Touchscreen Issues: Slow response, freezing, or complete failure of the touchscreen (often related to MCU1).
12V Battery Problems: Frequent jump starts, error messages related to low voltage, or premature battery failure.
Drive Unit Noise: Unusual whining, grinding, or clicking sounds coming from the motor.
Charging Problems: Slow charging speeds, error messages during charging, or inability to charge at certain charging stations.
Suspension Issues: Noises or uneven ride height from the air suspension.
Door Handle Issues: Failure of the automatic door handles to present or retract.
HVAC Problems: Weak or inconsistent climate control, strange noises from the HVAC system.
Premature Battery Degradation: Noticeable drop in range compared to original specifications.
Phantom Braking: Sudden, unexpected braking events, especially while using Autopilot.
Water Leaks: Leaks into the cabin, particularly around the sunroof or taillights.

Root Causes and Details

Understanding the root cause helps you grasp the severity of the problem and evaluate potential solutions. Here are a few examples linked to the Model S's launch timeline:

MCU1 Failure (Early Models):

The Media Control Unit (MCU1) in early Model S vehicles was based on the NVIDIA Tegra chipset. Over time, the eMMC NAND flash memory on the MCU can degrade, leading to slow performance, freezes, and eventually complete failure. Tesla eventually offered a paid upgrade to MCU2, which is based on an Intel Atom processor and significantly more robust.

12V Battery Issues (All Model Years):

The 12V battery is responsible for powering auxiliary systems. In the Model S, especially early models, the 12V battery is under constant load and can degrade quickly, especially in vehicles that aren't driven frequently or are subjected to extreme temperatures. Early charging algorithms also weren't optimal for maintaining the 12V battery health, leading to premature failure. Frequent short trips can also exacerbate this issue.

Drive Unit Failures (Early Models):

Early drive units (especially in the P85 and P85+) were prone to bearing failures and oil leaks. These issues were often caused by manufacturing defects or inadequate lubrication. Later drive unit revisions addressed these problems with improved bearings, seals, and lubrication systems.

Air Suspension Issues (All Model Years):

The air suspension system, while providing a comfortable ride, can be prone to leaks in the air struts, compressor failures, and issues with the height sensors. The problem is made worse in cold climates or areas where roads are heavily salted during the winter. Rubber components tend to fail over time due to wear and tear.

What Happens If Ignored?

Ignoring these symptoms can lead to more serious problems and increased repair costs. For instance:

MCU1 Failure: A completely failed MCU renders the touchscreen unusable, affecting climate control, navigation, and even some safety features.
12V Battery Failure: A dead 12V battery will prevent the car from starting or operating, leaving you stranded.
Drive Unit Failure: A failing drive unit can lead to complete motor failure, requiring a costly replacement.
Air Suspension Failure: A failed air suspension system can result in a bumpy ride, uneven ride height, and potential damage to other suspension components. This can also effect the handling and safety of your Model S.

Recommended Fixes

Here are some recommended fixes for common Model S problems:

MCU1 Failure:

The most effective solution is to upgrade to MCU2. This involves replacing the entire MCU unit with a newer, more reliable model. While it's a costly upgrade, it significantly improves performance and provides access to newer features.

12V Battery Issues:

Replace the 12V battery with a high-quality replacement. Consider using an AGM (Absorbent Glass Mat) battery, which is more resistant to vibration and deep discharge. Additionally, ensure the battery terminals are clean and properly tightened. Regular testing of the 12V battery is also recommended. Some owners have reported success by installing a dedicated trickle charger.

Drive Unit Failures:

If you experience unusual noises or performance issues, have the drive unit inspected by a qualified technician. Depending on the severity of the problem, you may need to replace the bearings, seals, or the entire drive unit. Proper lubrication and regular maintenance can help prevent future failures.

Air Suspension Issues:

Inspect the air struts, compressor, and height sensors for leaks or damage. Replace any faulty components. Consider using a desiccant dryer to remove moisture from the air suspension system, which can help prevent corrosion and extend the life of the components. Regular cleaning of the suspension components is also important, especially in areas with harsh weather conditions.

Cost Estimates and Shop Advice

Repair costs can vary depending on the severity of the problem and the location of the repair shop. Here are some rough estimates:

MCU2 Upgrade: $1,500 - $2,500 (including parts and labor).
12V Battery Replacement: $200 - $400 (including parts and labor).
Drive Unit Replacement: $5,000 - $10,000 (depending on the model and source of the drive unit).
Air Suspension Strut Replacement: $800 - $1,500 per strut (including parts and labor).

Shop Advice: When choosing a repair shop, look for one that specializes in Tesla vehicles and has experienced technicians. Independent Tesla service centers often offer competitive pricing compared to Tesla service centers. Be sure to get a detailed estimate before authorizing any repairs.

Technical Service Bulletins (TSBs) and Community Data

Tesla issues Technical Service Bulletins (TSBs) to address common problems and provide repair procedures. While Tesla TSBs aren't publicly available like those from other manufacturers, a qualified Tesla service center will have access to them. Always ask if there are any relevant TSBs for your specific issue. Additionally, online Tesla communities and forums are valuable resources for gathering information about common problems and potential solutions. These communities often share experiences and provide insights that can help you diagnose and resolve issues with your Model S.

For instance, there are numerous threads and discussions related to MCU1 failures, 12V battery issues, and drive unit problems in early Model S vehicles on forums like the Tesla Motors Club and Reddit's r/TeslaMotors. Many owners have documented their experiences and provided detailed information about the symptoms, root causes, and recommended fixes. Leveraging these resources can empower you to make informed decisions about your car's maintenance and repair.

By understanding when the Model S came out, recognizing the common symptoms of early production issues, and exploring available resources, you'll be well-equipped to diagnose and address any problems you encounter with your Tesla. Remember to stay informed, consult with qualified technicians, and leverage the power of the Tesla community.
