A firmware diagnosis feature is being introduced on Model 3 and Model Y vehicles that monitors wheel alignment over time. This feature detects changes in wheel alignment that may be related to incorrect tire pressures, degraded ball joints, bushings or damaged suspension links. If the feature determines that an inspection at a Tesla Service Center is required, a customer-facing alert will appear on the touchscreen.

What stands out
Of the 6 model years of Tesla Model 3 we track for suspension problems, this one carries the most owner complaints on file — 130.
Owners have filed 130 suspension complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering suspension on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
Certain Model 3 high voltage batteries may not have a sufficient quantity of bolts for the contactor DC link busbars, which may prevent the vehicle from charging or powering properly.
full bulletin at NHTSA ↗On certain Model 3 vehicles, the front stabilizer bar link ball joint studs might crack at the flange. As a result, the nut that attaches the stabilizer bar might lose torque. This might result in noise coming from the front of vehicle while driving on rough surfaces.
full bulletin at NHTSA ↗On certain Model 3, Model Y, and Model X vehicles, there may be a water ingress path to both front upper control arm ball joints that, over time, could possibly lead to surface corrosion of these ball joints. This may result in a creaking sound coming from the front suspension when steering at low speeds and under high loads. This is exclusively an NVH condition only and does not result in premature failure of the ball joints.

The failure pattern owners describe
The 2018 Tesla Model 3 suspension shows a persistent pattern of premature wear and fastener failure. The most common issue is loosening or separation of the lower lateral link bolts that secure the suspension to the subframe—owners report these fasteners backing out and falling completely off at mileage between 20,000 and 80,000 miles. When this happens, steering becomes difficult or impossible, and the vehicle requires towing.
Upper and lower control arm cracking is also widespread. Owners describe creaking or squeaking noises when turning or driving over bumps, often requiring replacement of the arm. A Tesla technician explicitly told one owner that the control arms are undersized and that the shop replaces them nearly daily on Model 3s. Suspension bushings and compliance links tear prematurely, sometimes at 27,000 miles.
Several owners report finding bolts in driveways or discovering broken fasteners during routine service—evidence the bolts failed under normal driving rather than impact. A few owners note helicoil inserts already in place at the factory, indicating stripped threads that Tesla had to repair before delivery. The most dangerous failures involve ball joint stems snapping and lateral links separating without warning, turning the steering uncontrollable at highway speeds.
Tesla's response varies. The company has issued recalls 21V-835 and 23V235000 for lateral link fastener issues, but many affected VINs fall outside the recall window. Out-of-warranty repairs frequently cost $1,500–$5,000, with Tesla refusing coverage and claiming the issue is normal wear. Service bulletins provide temporary fixes (sealant application) that do not stop recurrence.

Failure modes owners describe
Upper Control Arm Cracking and Failure
Front upper control arm develops cracks, usually accompanied by creaking or squeaking noises when turning or driving over bumps. Owners report the aluminum components cannot support the vehicle weight. Tesla technicians tell owners this is a daily repair. Failures occur early in vehicle life, sometimes requiring multiple replacements.
When: Typically 21,000–60,000 miles; some instances within first 3 years of ownership
Symptoms owners cite: Loud creaking, squeaking, or squealing when turning steering wheel; Noise over bumps or uneven road surfaces; Diminished control feel while steering
Repairs/costs cited: Replacement of one or both front upper control arms; labor and parts vary. Owners cite costs from $92 (parts only) to $1,850+ when combined with lateral links and compliance links. Tesla applied Service Bulletin SB-20-31-006 (sealant application) as temporary fix; later replaced with SB-23-31-001 for lateral link fastener work.
Recalls/TSBs owners mention: Service Bulletin SB-20-31-006 (sealant sealing of ball joints); later replaced. Tesla states defects are 'normal wear and tear' despite low mileage. No recall specifically for upper control arm alone; only covered under lateral link recalls 21V-835 and 23V235000 for affected VIN ranges.
Lower Lateral Link Fastener Loosening and Separation
Bolts securing the lower lateral link to the subframe loosen or back out completely, allowing the lateral link to separate from the subframe. This can happen without impact. The link then hangs loose or contacts the ground, creating instability and potential loss of steering control. Multiple owners describe finding bolts in driveways or ground.
When: Failure occurs between 20,000–95,000 miles; many reported failures at 30,000–70,000 miles
Symptoms owners cite: Clunking or clanking noise when turning at low speeds; Rattling over uneven road surfaces; Steering wheel feels loose or requires increased effort; Vehicle pulling to one side; Bolt falls out or hangs from suspension; may be found on ground
Repairs/costs cited: Tightening or replacement of lateral link bolts and fasteners. Full lateral link replacement if damaged. Some owners cite subframe replacement costs of $500–$3,500+ depending on extent of damage. Out-of-warranty repairs often charged to owner despite recall applicability.
Recalls/TSBs owners mention: Recalls 21V-835 (original 2019–2020 Model 3, 2020–2021 Model Y) and 23V235000 (expanded to 2018–2019 Model 3). Recall work includes tightening or replacing fasteners free of charge, but VIN ranges exclude many affected vehicles. Technical Service Bulletin SB-21-31-001 and later SB-23-31-001 address the issue but only for recalled VINs.
Lower Compliance Link and Lateral Link Bushing Deterioration
Bushings and elastomer components in lower compliance links and lateral links tear, crack, or wear prematurely. This is often discovered during inspection for noise complaints. Multiple failures on the same vehicle are common.
When: 27,000–58,000 miles reported
Symptoms owners cite: High-pitched creaking or squeaking when turning or over bumps; Grinding noise, especially during low-speed turns; Suspension vibration and shaking at various speeds
Repairs/costs cited: Replacement of both left and right lower compliance links and lateral links. Costs reported from $1,300–$2,100+ for complete front suspension work. Some estimates show parts costs of $1,020 plus labor of $245.
Recalls/TSBs owners mention: No specific recall; treated as maintenance item outside warranty. Some technicians acknowledge the problem but claim it is due to vehicle weight or driving conditions.
Lateral Link Bolt Fracture and Two-Piece Bolt Failure
Bolts that secure lateral links and control arms snap or fracture, particularly at welded joints if two-piece construction is used. Snapping occurs in brittle fracture mode near the weld. Some bolts break during normal driving; others may be under-torqued at assembly.
When: Variable; failures reported from low mileage (1,000 miles) to higher mileage (70,000+)
Symptoms owners cite: Loud bang or crack while driving; Suspension becomes loose immediately after fracture; Loss of steering control or severe steering effort required; Wheel may angle sharply inward or outward; Bolt may fall to ground
Repairs/costs cited: Replacement of fractured bolt and fastener. Full lateral link or subframe replacement if secondary damage occurs. Costs vary widely but can reach $2,000–$5,000+ if subframe or body work is needed.
Recalls/TSBs owners mention: No specific recall for bolt fracture. Related to recalls 21V-835 and 23V235000 (fastener tightening/replacement) but those focus on loosening, not fracture. No TSB addressing casting or bolt quality.
Suspension Ball Joint Popping and Stem Fracture
Ball joint sockets pop apart or ball joint stems snap in brittle fracture mode. Upper and lower ball joints are affected. Owners and concerned citizens note multiple vehicles in salvage yards with snapped ball joint stems and no collision damage, suggesting a systemic casting or material defect.
When: Low to moderate mileage; some failures under 50,000 miles
Symptoms owners cite: Loss of steering control or unstable handling; Wheel angles sharply or vehicle becomes uncontrollable; Suspension component physically separates or breaks
Repairs/costs cited: Ball joint replacement or full control arm assembly replacement. Costs typically included in larger suspension rebuild jobs ($1,500–$5,000+).
Recalls/TSBs owners mention: No specific recall for ball joint fracture. Issue cited by owners as similar to known defects in Model S and Model X; no proactive manufacturer action documented in narratives.
Subframe Damage from Lateral Link Separation
When lateral link fasteners fail or bolts fall out, the subframe itself sustains damage. Weld nuts that were captive-welded to the subframe during assembly shear off. This compounds repair costs and complexity.
When: Concurrent with lateral link fastener failure; 30,000–81,000 miles reported
Symptoms owners cite: Clunking or clanking from front end; Suspension component hangs loose or drags; Visible body damage if component impacts fender or door
Repairs/costs cited: Subframe replacement in addition to suspension component replacement. Estimates include $2,000–$5,000+ for full repair including body work.
Recalls/TSBs owners mention: No recall specifically for subframe damage. Covered indirectly under lateral link recalls if VIN is included, but many owners' VINs are excluded. Tesla refuses to cover repair costs outside recall range.
Helicoil Thread Repair at Factory (Bolt Hole Stripping)
Owner discovered helicoil inserts already in place in suspension bolt holes during routine maintenance. This indicates the factory had to repair stripped threads before delivery, suggesting assembly quality issues. Concerns about long-term durability of helicoil repair.
When: Present at time of repair; unknown original timing
Symptoms owners cite: Difficulty reinstalling bolts; Risk of bolt loosening if helicoil fails
Repairs/costs cited: Owner re-installed bolt with helicoil but withheld full torque due to safety concern. No further service recommended by Tesla beyond visual inspection after warranty expiration.
Recalls/TSBs owners mention: Tesla advised customer to visit service center but offered only visual inspection when warranty expired. No acknowledgment of factory defect or responsibility for helicoil installation.

Here is a Tesla model 3 in the junkyard. Https://www.copart.com/lot/60799809/photos it has not been in a collision, no air-bags have deployed. The front suspension has snapped apart. The cast alloy lower suspension arm has broken in half. This is clear evidence of a casting defect. It is most interesting that the high profile legal action over a suspension failure -…
Front suspension components needed to be replaced, vehicle was out of warranty and had only 43000 miles. These parts should last for much longer the 4 years and 43000 miles. No incident, but car squeaked at all speeds. Repair cost was $1600
Tesla replaced the upper control arm assembly in February 2021 after I complained that there was a squeaking noise when moving the steering wheel. My car and components are available for inspection. I was concerned that the front suspension would break leading to an accident. Tesla inspected and confirmed the issue. No warnings or message were displayed by the car.
At only 30,000 miles, the car began exhibiting terrible creaking sounds during colder temperatures whenever the suspension was active. Upon inspection, a Tesla technician claimed the ball joints on the upper control arms were “worn” and bushings on the lateral links were “torn”. Looking online, it’s clear this was due to defensive design/manufacture, as it’s happened to numerous vehicles. It…
Control arm of the left front suspension system detached with no warning other than an occasional noise that started about 2 weeks before the incident, usually when turning the front wheels at slow speed. This was a potentially dangerous situation for the driver, passengers, and any other vehicles on the road as the tire could have come off at any time. Fortunately the car was being parked (0-1…
After taking in my Tesla Model 3 for a loud creaking noise coming from the front right suspension, the Tesla service specialist said the suspension control arms are cracked and the car is dangerous to drive. I asked how this is possible. The Tesla specialist said the suspension is made of aluminum and cannot support the weight of the car. He said this is a known issue. However I was told I need…
