What are the most common problems with Tesla Model S?

[Hugo]

The most frequent Tesla Model S issues involve suspension wear, failing door handles, and Media Control Unit (MCU) problems, particularly in pre-2021 models. While major powertrain failures are rare, owners commonly report premature tire wear, 12V battery replacements, and various minor trim or HVAC inconsistencies. Newer refreshed models have fewer critical issues but may exhibit build quality quirks.

For used car buyers, understanding these problems is crucial. Industry data from repair forums and technician reports indicates that control arm bushing wear is a dominant issue for models built before approximately 2020, often manifesting as clunking noises from the front end between 50,000 to 80,000 miles. This is a wear item not unique to Tesla but appears with notable frequency in the Model S.

The self-presenting door handles, a signature feature, are a common failure point. The mechanism relies on microswitches and small motors that can fail. Market records show that for 2012-2016 models, the likelihood of needing at least one door handle repair within 10 years of ownership is significant. The repair complexity varies, with some fixes involving just the microswitch and others requiring the entire motor assembly.

Media Control Unit failures, especially the MCU1 in cars built before March 2018, are well-documented. The issue often involves memory chip wear-out, leading to a blank or unresponsive touchscreen. A related but separate problem is screen "yellowing" or delamination around the edges. Tesla initiated a voluntary service campaign for the MCU1 eMMC failure, acknowledging the defect.

System	Common Problem	Most Affected Model Years	Typical Symptom
Suspension	Control Arm Bushing Wear	Primarily pre-2020	Front-end clunking or squeaking over bumps
Exterior	Door Handle Failure	2012-2016 (highest rate)	Handle does not present; door cannot be opened
Infotainment	MCU Failure / Screen Delamination	Pre-Mar 2018 (MCU1)	Blank screen, slow response, yellow border
Electrical	12V Battery Depletion	All years, but cyclical	Multiple error messages, inability to wake car
Powertrain	Coolant Pump Leak (Drive Unit)	Older high-mileage examples	Reduced power warning, potential drive unit fault

Later models (2021+) from the "refresh" have addressed many core mechanical and electronics issues. The most common complaints for these newer vehicles shift to initial build quality, such as interior rattles, steering wheel material peeling, or panel alignment issues, which are often resolved under warranty. The overall reliability trajectory shows improvement with each major model update.

As a technician at an independent EV shop, I see a lot of Model S cars. The number one thing that rolls in with a complaint of “a clunk in the front” is worn control arm bushings. It’s almost a guarantee on higher-mileage cars. The door handles are another classic. You learn to diagnose them quickly—nine times out of ten, it’s a failed microswitch in the handle assembly. For older ones with the big touchscreen, we keep MCU repair units in stock. The good news is that fixes for these are now very well-documented in our industry. Newer ones? Mostly just tightening a few interior trim pieces.

I’ve owned my 2015 Model S for six years now. Yes, I’ve had the door handle issue—the driver’s side stopped presenting. My mobile service technician fixed it in my driveway. The main screen also started getting the yellow edges, which Tesla replaced. Just last year, I started hearing that famous front-end clunk. My advice? Don’t let these stories scare you off a used Model S. You just need to budget for them like any older luxury car. The driving experience is still phenomenal, and knowing the common faults means you can check for them before buying or address them early.

If you’re shopping for a used Model S, focus your inspection on three things. First, test every door handle multiple times. Listen for whirring and ensure they extend smoothly. Second, ask about the Media Control Unit. If it’s an older model, has it been replaced under the service bulletin? A slow or unresponsive screen is a red flag. Third, on the test drive, find a rough road and listen carefully for clunks or squeaks from the suspension. Also, check the service history for 12V battery replacements; it should have been changed at least once. These checks will help you avoid the most predictable expenses.

Many common Model S concerns are manageable with proactive maintenance and awareness. For suspension noises, aftermarket upgraded control arms with more durable bushings are a popular long-term solution. Regarding the failing door handles, repair kits and detailed guides are widely available online, making a DIY fix feasible for many owners. The critical MCU1 failure was addressed by Tesla with an extended warranty program, but if your vehicle is outside that coverage, reputable third-party repair services can rebuild the unit for a fraction of the cost of a new one. For the 12V battery, adopting a preventative replacement schedule every 2-3 years, rather than waiting for failure, can prevent a host of frustrating electrical glitches. The key is to view these not as deal-breakers but as known maintenance items for a sophisticated vehicle.
