2021 TESLA MODEL Y Complaints

On or about XXX my Tesla Model Y downloaded FSD version 14 Lite. One day after downloading the software, I used FSD and the new software caused the computer to overheat. This killed the car computer and made FSD, adaptive, cruise control, lane keep assist, reverse camera, and many other functions, including GPS and navigation inoperable. My car’s warranty expired in January of this year and Tesla will not cover the replacement car computer. There are hundreds of other complaints of this issue reported online on [XXX], Reddit, Facebook, etc. In the 2nd quarter Tesla Earnings Call, [XXX] declared that hardware 3 equipped Tesla vehicles would not be able to support autonomous driving with full self driving. He stated every hardware 3 vehicle will need to be updated with a hardware 4 computer and cameras. Since my hardware 3 computer failed, I requested the hardware 4 computer and cameras to be installed, but Tesla denied this service even though [XXX] said it was a requirement.

In the 5 years we have had this vehicle there have been multiple issues with the Self Driving feature including: 1)Phantom braking on busy freeways in [XXX] 2)Swerving randomly into the other late on a curve on 4 lane hwy at 65 mph ([XXX] near [XXX]) 3)Attempting to switch lanes into fast traffic when we were at a standstill in rush hour traffic ([XXX]) 4)Slamming brakes on on a 2 lane road on a curve because there was a semi in the other lane (that had not crossed the line) [XXX] 5)Being a short way from exiting the freeway and having the car jump back into traffic ([XXX] at [XXX]) 6) Slammed on brakes when the car in front of us was exiting [XXX] normally on an offramp going northbourd around the city of [XXX]. These are some of the most egregious errors the car has made, but there are more not listed. I try it on occasion when there is a software update. It is not safe though- almost without fail I need to take over each time I try it. As [XXX] said on XXX "Hardware 3 simply does not have the capability to achieve unsupervised FSD due to physical computing and memory limitations." The full self driving is dangerous, yet each time I get in the car the computer encourages its use. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I brought the vehicle to a Tesla Service Center for a front suspension noise. During the alignment portion of that repair, the technician found a crack in the left side of the rear subframe casting, the structural member that locates the rear suspension links and supports the rear drive unit. The subframe required full replacement. There was no impact event. The vehicle has never struck a curb, pothole, or object, and Tesla's own written finding confirmed there was no evidence of any side impact. Tesla attributed the crack to stress transmitted from failed front lower control arm bushings, which were replaced at the same visit. The front lower lateral links and their subframe fasteners were also replaced during this repair. The Tesla technician stated he had not seen this subframe crack so severely at this mileage, and that he normally sees this failure only on vehicles over 100,000 miles, or vehicles that have hit severe potholes or fallen off steep curbs, none of which applies here. A rear subframe cracking under normal driving loads at 68,000 miles is a structural failure with safety implications. The subframe controls rear wheel alignment and retains the drive unit. Progressive or sudden failure could cause loss of alignment, instability, or loss of vehicle control. I am reporting this so NHTSA can determine whether premature rear subframe cracking, potentially linked to front suspension link failure, represents a defect trend on these vehicles.

My garage-kept 2021 Tesla Model Y experienced a premature failure/tearing of the front lower lateral link and compliance bushings at only 31,930 miles under normal driving conditions. The service center identified severe degradation requiring immediate replacement. This component failed prematurely without any severe impact or road hazards, posing a potential safety hazard regarding vehicle control and alignment. This issue appears to be part of the ongoing suspension defect under NHTSA investigation (PE26006). Funny thing is that my dad's model Y also has the similar issues on the rear suspension. sigh...

My 2021 Tesla Model Y developed a steering system/EPAS fault identified in Tesla Service Mode as EPAS3P_a072_motFeedFwdError, along with UI_a020 Steering Assist Reduced. Tesla diagnosed the vehicle as requiring replacement of the steering rack/EPAS assembly. Tesla informed me in writing that the vehicle may experience intermittent or complete loss of electronic steering assistance, that the vehicle is not operating within manufacturer safety specifications, and that Tesla advises against operating the vehicle until the steering rack is replaced. Tesla also confirmed that there is currently no applicable recall or service campaign for my VIN. I am reporting this because failure or loss of electronic power steering assistance presents a significant safety concern, particularly if steering assistance is lost unexpectedly while the vehicle is being operated. Vehicle: 2021 Tesla Model Y VIN: 5YJYGDEE6MF207395 Mileage: approximately 129,281 Tesla diagnostic fault: EPAS3P_a072_motFeedFwdError Related alert: UI_a020 Steering Assist Reduced I request that NHTSA review this complaint and determine whether similar steering/EPAS failures are occurring in other Model Y vehicles and whether this represents a broader safety defect.

The electronic power steering (EPAS) system/steering gear malfunctioned. Tesla diagnosed fault code EPAS3P_A072_mot and recommended replacement of the steering gear/rack, part number 1188832-00-B. The vehicle is currently available for inspection upon request. If the steering gear is replaced, I will request that the failed component be retained or otherwise made available for inspection if possible.The vehicle displayed a warning stating “Steering Assist Reduced Steering May Require Increased Effort.” A reduction or loss of electronic power steering assistance could require significantly greater steering effort and could affect the driver's ability to safely maneuver the vehicle, particularly during turns, low-speed maneuvers, or an emergency maneuver. I was concerned that the steering assistance could further deteriorate or fail unexpectedly while driving, putting the driver, passengers, and other road users at risk.The problem was confirmed by a Tesla Service Center. Tesla diagnosed fault code EPAS3P_A072_mot and determined that the steering gear/rack requires replacement. Tesla recommended the replacement of the steering gear part number 1188832-00-B and provided an estimate of approximately $3200.The vehicle was inspected by Tesla technicians at the Tesla Service Center. I specifically asked Tesla to determine whether a pothole impact could have caused the steering rack failure. After inspecting the vehicle, Tesla informed me in writing that its technicians did not observe any signs of impact damage and that Tesla does not believe the pothole incident caused the current steering rack failure. The vehicle has not been inspected by police or insurance representatives. The vehicle displayed the warning message “Steering Assist Reduced / Steering May Require Increased Effort.” The warning first appeared on or about 8-25-26 at approximately 136K miles. I subsequently brought the vehicle to Tesla for diagnosis, where Tesla identified fault code EPAS3P,recommends rep

I own a 2021 Tesla Model Y with approximately 51,300 miles. Beginning in June 2026 I noticed a persistent creaking noise from the front suspension, most audible when accelerating and when turning at low speed. The vehicle had been rear-ended in June 2026 and repaired at a body shop; the noise was reported to the shop at that time and persisted after the repair was completed. On September 2, 2026 I brought the vehicle to a Tesla Service Center for diagnosis. The technician test drove the vehicle, verified the noise, and performed an inspection on a lift. The written findings were that both front upper control arm ball joints were partially seized, both front lateral link bushings were torn, and both front compliance link bushings were torn. Tesla recommended replacement of the front upper control arms, front lower lateral links, and front lower compliance links, quoted at approximately $2,610 at my own expense. Tesla further stated that a four-wheel alignment could not be accurately performed in the vehicle's current condition because of the torn bushings. No crash, fire, or injury has resulted. The vehicle remains in service. I am filing this complaint because these are the same front suspension components identified in NHTSA's open investigation into front suspension link separation in Model 3 and Model Y vehicles, and my vehicle falls within the model years under review. The failure is bilateral and occurred with no impact to the front of the vehicle and no off-road or track use. I am concerned that degraded bushings and seized ball joints across all three component types create a risk of link separation and loss of steering control without meaningful warning beyond the creaking noise.

My passenger rear door is completely broken and unsafe. While I am driving down the road, the car suddenly thinks the door is wide open (ajar) because the window won't roll up all the way. It triggers the car alarm to blast violently while I am actively driving, which is terrifying and distracting. When parked, the car won't lock, leaving it totally unsecured. I have paid Tesla $500 over three separate visits to fix this safety hazard, but their technicians have completely failed to fix it, and it keeps happening while the vehicle is in motion. I was told this is a known issue, but they still cannot fix it, there should be a recall in place for anyone else with this issue and Tesla should fix it without billing their customers.

Rear passenger door is impossible to open. On using the exterior latch, the window retracts partly and the door opens 1/2 inch only. From inside, nothing works and a passenger would be trapped. Please have Tesla fix this - a very known problem, there are youtubes videos complaining about this door problem - always the same door too - so Tesla knows this is a problem.

I am submitting this safety complaint regarding premature suspension failure on my 2021 Tesla Model Y (VIN: [XXX]), specifically concerning the front lower suspension links.During a dealer inspection at a Tesla Service Center on XXX, with 72,758 miles on the odometer, technicians diagnosed that the vehicle’s front lower lateral links and front lower compliance links suffered from severely torn factory air-gap rubber bushings. The degradation of these critical structural components required immediate, full replacement of the entire arm assemblies to ensure safe operational handling, resulting in an out-of-pocket repair quote of $1,976.57 (Tesla Invoice #XXX). A compromised or torn bushing in the lower lateral link assembly compromises structural integrity, increasing the risk of mechanical detachment or fracture while in motion, which poses a severe loss-of-control safety risk at highway speeds. This issue directly correlates to the high failure rates and premature degradation profiles currently being investigated by the Office of Defects Investigation under active NHTSA Probe PE26006. I request that this case data point be reviewed as further evidence to transition this active preliminary evaluation into a mandatory, formal safety recall for the protection of all affected owners.
