According to Au7o's research across NHTSA recalls, manufacturer TSBs, and owner forum reports, the 2020 Tesla Model Y has 7 documented known issues, with 2 rated critical. The most serious are Front Suspension Lateral Link Bolts Loose - Separation Risk (Recall 21V-835) ($0-$0 repair) and Heat Pump / Octovalve Failure in Cold Weather (Loss of Cabin Heat and Defrost) ($0-$5,000 repair). Across all issues with published estimates, repair costs range from $600 to $5,000. DIY maintenance guides at au7o.io.
On the 2020-2021 Tesla Model Y, on 2020-2021 Model Y built March 2020-June 2021, the two fasteners connecting the front lower control arm (lateral link) to the subframe were not torqued to spec at the factory. The bolts can back out over time, allowing the lateral link to separate from the subframe and causing sudden loss of wheel alignment and steering control. NHTSA Recall 21V-835 / Tesla SB-21-31-003 covers inspection and re-torque.
Common Symptoms
Clunking from front suspension over bumps
Wandering steering
Uneven tire wear
Visible loose or missing bolt at subframe
Sudden alignment shift after pothole
How to Fix
Check VIN at nhtsa.gov/recalls for open 21V-835 status. Tesla Service inspects and re-torques (or replaces) the lateral link fasteners free of charge. Do not delay - this is a separation-risk recall.
On the 2020-2024 Tesla Model Y, 2020-2024 Model Y (especially Performance trim, which sits ~10mm lower) is delivered with aggressive, non-adjustable rear negative camber that causes severe inner-edge wear on the rear tires. The factory rear camber cannot be changed via standard alignment — only toe is adjustable. Owners commonly replace rear tires every 15-25k miles, with some Performance owners going through 3 sets in 60k miles. The 400+ lb-ft of instant rear-wheel torque combined with the vehicle's 4,400-4,600 lb weight amplifies the wear.
Common Symptoms
Smooth/balding inner shoulder of rear tires while outer is fine
Cords or wear bars showing on inner edge under 25k miles
Cupping or feathering on inner rear tread
Pull or off-center steering wheel from delivery
How to Fix
Get a four-wheel alignment at first sign of inner wear. For lasting fix, install adjustable rear camber arms (N2itive, MPP, Unplugged Performance) and re-align to about -1.0deg camber with neutral toe. Rotate tires every 5-6k miles thereafter.
On the 2020-2022 Tesla Model Y, on 2021-2022 Model Y, the heat pump's Electronic Expansion Valve (EXV) in the Octovalve supermanifold can stick open if controller communication is interrupted, causing total loss of cabin heat and defrost in sub-freezing temperatures (especially -10C/14F or colder). In severe cases the AC compressor and Octovalve must be replaced. Tesla recalled ~26,681 vehicles (NHTSA 22V-050, Feb 2022) across Model S/X/3/Y running firmware 2021.44 through 2021.44.30.6 for the software-related issue, but hardware failures also occur, especially in extreme cold.
Common Symptoms
No cabin heat
Windshield will not defrost
HVAC blows cold air only
Heat pump runs but no warmth
Warning message about climate system
How to Fix
Update firmware to 2021.44.30.7 or later per NHTSA recall 22V-050. If heat is still lost, request Tesla Service inspect the Octovalve and AC compressor; warranty covers replacement on most 2021-2022 vehicles.
On the 2020-2023 Tesla Model Y, 2020-2023 Model Y crossovers built at Fremont and Giga Austin can leak water into the rear trunk and subtrunk through gaps around the liftgate lamp studs and connector, and through inadequate liftgate sealing. Owners report standing water in the spare-tire well, soaked carpet, and water cascading out when the trunk is opened after rain. Tesla released SB-23-10-003 (April 2023) to reseal the assembly.
Common Symptoms
Water pooling in subtrunk / spare-tire well
Wet trunk carpet after rain or car wash
Water streaming out when opening the liftgate
Musty smell from rear of cabin
Corrosion on trunk-mounted electronics
How to Fix
Request service under TSB SB-23-10-003. Tesla replaces the liftgate lamp double-ended stud gaskets and connector gaskets and applies polymer sealant (about 1.8 hours of labor, covered for many owners). Dry the subtrunk fully first to prevent mold.
On the 2020-2022 Tesla Model Y Dual Motor, early-production (2020-2021) Model Y reports of the panoramic rear glass cracking, sometimes spontaneously, sometimes from minor flex. Owners reported cracks appearing during cold-weather closing of the trunk. Tesla covered most under warranty but did not recall. Issue largely resolved in later builds.
Tesla goodwill or warranty replacement (~$700-$1,200) — file a service request promptly. Out-of-warranty rear glass replacement $800-$1,400 + install ($300-$500). 3rd-party glass shops may quote less than Tesla service center.
On the 2020-2024 Tesla Model Y, leaving Sentry Mode and/or Cabin Overheat Protection enabled on 2020-2024 Model Y causes 7-14% HV pack drain per day plus accelerated 12V battery cycling, because the car keeps the HV system live, cameras recording, and the Autopilot computer processing video continuously. Owners report dead 12V batteries, range anxiety, and inability to drive after a few unplugged days. Tesla added throttling in 2024.32.6 and a ~40% reduction in 2024.38.4, but baseline drain remains substantial.
Common Symptoms
Phantom drain of 5-15% per day when parked
12V battery dead after several unplugged days
Premature 12V battery replacement (often <2 years on early lead-acid units)
'Vehicle may not restart' / 'Power reduced' 12V low warnings
Car cannot wake or shift to Drive after parking
How to Fix
Update to 2024.38.4 or later (40% drain reduction via FSD-computer motion detection offload; MCU stays asleep until video write). Use 2024.32.6+ behavior that cuts 12V outlets/USB in Sentry. Disable Sentry Mode and Cabin Overheat Protection during long-term parking, or whitelist home/work. Replace the 12V battery if drain persists: 2020-2021 and early 2022 builds are flooded lead-acid; production starting late December 2021 transitioned to a 15.5V Li-ion module — do NOT cross-fit the wrong chemistry.

On the 2020-2025 Tesla Model Y, software release 2024.38.3 introduced a defect on 2020-2025 Model Y (and 2017-2025 Model 3, 2024 Cybertruck) vehicles in which the tire pressure monitoring system warning telltale would reset when the vehicle was powered down or went to sleep between drives. As a result, the low-tire-pressure warning light did not remain illuminated across drive cycles as required by FMVSS 138, so a driver could begin a new trip unaware that a tire was still under-inflated. The recall covers approximately 694,000 vehicles.
Common Symptoms
Low tire pressure warning light disappears after the car sleeps or powers down
TPMS telltale not illuminated at start of a new drive despite low pressure
No persistent under-inflation warning between trips
How to Fix
Tesla pushed a free over-the-air firmware update (release 2024.38.7, 2024.38.10, 2024.40 or later, excluding 2024.44/2024.44.1) that restores compliant TPMS telltale behavior so the warning persists between drives. No service visit is needed.
Tesla, Inc. (Tesla) is recalling certain 2024 Cybertruck, 2017-2025 Model 3, and 2020-2025 Model Y vehicles. The tire pressure monitoring system (TPMS) warning light may not remain illuminated between drive cycles, failing to warn the driver of low tire pressure. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 138, "Tire Pressure Monitoring Systems."
