High voltage battery pack failed. It is available for inspection. No one was affected by the issue when it occurred. Tesla has inspected it and stated it has imbalance, and entire high voltage battery pack needs to be replaced. Yes, there is a warning messages on the screen. (BMS_a079 - Unable to charge - Maximum charge level reached) ...but only shows 50% State of Charge The issue happened randomly while the car was parked yesterday 7/29/2026

This is for a recurring front passenger safety restraint system defect on a 2021 Tesla Model Y, VIN [XXX]. The defect has now resulted in at least six service visits or invoices involving the same front passenger restraint / occupancy system concern, and Tesla has now charged $1,582.18 for another repair involving the front passenger seat cushion trim and seat back trim even though prior repairs did not permanently correct the condition.

Hello, We have 46224 miles on the car currently. A couple of weeks back the whole battery died. Tesla replaced the battery and we picked up the car this past Friday, the XXX. After picking up the car the driver's seat does not slide. I looked it up online on the Tesla website as well as on the app and at both the places it was strongly recommended to bring the car back to Tesla as the problem was very very likely secondary to the battery replacement. the seat does not move at all. When I spoke to customer service at out local Tesla dealership in [XXX], the earliest date they could provide us was in the first week of August! This is an urgent issue. We happen to be away on vacation that week. So we were told to review the cost estimate and then find a date on the app to bring the car in. When I questioned the estimate price, I was told that this was the worst case scenario. But the invoice clearly states Calibration, and 3 prices for a switch package all amounting to $364.45 with tax!!! Again I questioned this huge charge, considering the battery replacement and I was told almost rudely, "That does not seem to be the issue." Just not right!!

My car is having issues with downloading the software and installing it. It usually happens during the summer. 2025 summer i booked an appointment and visited the Tesla Service center. They diagnosed and told me the ECU is having trouble and need to replace same. Its cost around USD 4K. My car faced this issue right after the warranty is over. First the High Voltage batter died next day the warranty got over, but they replaced it under Battery Warranty. But ECU issue they want me to pay for the same. Its a huge cost and i do see lot of customers keep complaining about the same/similar issues all over internet. It looks like a wide spread issue which Tesla ECU fail after the warranty get over. Biggest challenge for the customers are, No Navigation, GPS is not working, All the cameras goes blind, Lane assistant doesn't work. dashcam recording doesn't work. Technically we can just charge the car and drive. No safety features work as expected.

The electronic power assisted steering (EPAS) rack on my 2021 Tesla Model Y experienced an internal electronic failure. The failure first occurred while the vehicle was performing an automated parking maneuver (Autopark) at low speed. The vehicle displayed the warning "Steering assist reduced / Steering may require increased effort" (alert UI_a020_SteeringReduced). Using the vehicle's built-in Service Mode, I retrieved the underlying diagnostic fault: EPAS3P_a072_motFeedFwdError, described by the vehicle as "Motor control feed-forward correlation error," set when the difference between estimated motor torque and commanded torque exceeds 1.2 Nm. The vehicle's own diagnostic screen lists the clear condition for this fault as "Replace EPAS," indicating an internal hardware failure of the primary EPAS module. The listed potential impact is "Reduced steering assist and EAC inhibited." The fault initially cleared after approximately three minutes but returned and is now latched: it persists through vehicle reboots and multiple drive cycles. While the fault is active, power steering assist is reduced and lane keeping assistance / active safety steering features are inoperative. Safety risk: steering assist can degrade without warning during low-speed maneuvers, requiring sudden and substantially increased steering effort, and lane keeping assistance is disabled. The failure occurred while an automated driving feature was in control of the steering, with no curb impact, collision, or abnormal use.

Recurring front passenger safety restraint system fault causing incorrect occupant detection for airbag deployment. Failed and was ‘repaired’ 3 times since 2024, including 2 consecutive failed repairs of the same part within the last 3 months. Tesla service advisor also mentioned informally this is a common issue. Tesla is now refusing further no-cost repair despite both recent repairs remaining under Tesla’s own parts warranty.

Error ui_a020 "steering assist reduced" appears without any noticeable steering changes at the moment, but with a warning that steering may become increasingly harder and harder. There were recent recalls on other models of Tesla.

Safety features on vehicle stopped working after software update was pushed to my vehicle. GPS, all cameras including backup camera and ones used for blind spots, and cruise control have all stopped working. Time displays incorrectly due to GPS issue and night mode stays on so rear view & back window stay dark making it hard to see other vehicles around me during the day. I’ve followed all recommended steps to resolve and issue persists.

Tesla model y is experiencing a front passenger airbag sensor failure (OCS) covered by factory bulletin SB-23-20-002 alongside TMPS and EAEB alerts. Tesla corporate resolutions is refusing to fix these safety system failures with out charging $1400 out-of-pocket, citing warranty expired.

The steering is not functioning properly. This is sealed system and no where else I can get it. This a safety issue and I haven't seen any car steering failing like this. Even cars as old as 20 year has no such issues. This is huge slap on of $3k+ on consumer. The cars is hardly 5 year old.
