Tesla’s Software Glitch Strips It of the Coveted Car‑of‑the‑Year Award

Breaking: Tesla Tech Glitch Costs Brand Car Of The Year, Sparking Industry Reassessment

Breaking news: a Tesla model faltered during a high-profile evaluation, leading to the brand not securing the coveted Brand Car of the Year award. The incident underscores the rising dominance of software and technology in modern vehicles and prompts a wider look at how reliability is measured in today’s mobility landscape.

The Tesla tech glitch was identified during testing and cited by the awarding body as a factor in the decision. While details remain limited, the event has intensified debate about the role of software quality and sensor integrity in defining true automotive excellence.

Industry observers say the episode reinforces the growing expectation that high-tech, software-defined cars must pass rigorous validation before they can claim top honors. Representatives for the brand did not offer immediate comment, while rival manufacturers used the moment to emphasize their own ongoing software development efforts.

What happened

During the evaluation period, testers flagged a technology fault tied to onboard software and related systems.The issue affected scoring in multiple categories, and the committee ultimately did not award the Brand Car of the Year title to the Tesla model under review.

Why it matters

The episode spotlights a broader industry shift: software reliability can tilt outcomes in awards that were once driven mainly by design and performance. As vehicles become more connected, the quality of updates, cybersecurity, and system integration increasingly influence consumer trust and brand reputation.

Industry and brand response

Analysts caution that the incident could accelerate calls for tougher software validation, obvious testing criteria, and clearer communication about OTA updates.Competitors are likely to highlight their own QA investments as a counterpoint to the stumble, while Tesla faces renewed scrutiny of its software governance and update cadence.

Evergreen insights: what this means for readers over time

As cars become rolling software platforms, awards and consumer perception will hinge more on software resilience, user experience, and the reliability of over-the-air updates. Key takeaways for buyers include tracking a vehicle’s software update history, understanding how updates affect safety features, and evaluating the robustness of help channels when issues arise.

For the industry,the message is clear: excellence today requires tighter QA,better end-to-end testing of digital systems,and stronger collaboration between hardware and software teams to avoid disruptive surprises in public evaluations.

6 second latency spike in the steering‑torque command loop.

The glitch that triggered the award reversal

• Date of discovery: 3 January 2026, during the final evaluation of the 2025 MotorTrend Car‑of‑the‑Year (COTY) test drive.
• model affected: 2025 Tesla Model Y Long Range (software version 2026.01).
• Core issue: An OTA (over‑the‑air) update introduced a race‑condition in the vehicle’s CAN‑bus gateway, causing the infotainment screen to freeze and the adaptive‑cruise‑control (ACC) module to misinterpret sensor data.
• Real‑world symptom: Drivers reported sudden loss of steering‑assist torque and erratic brake‑light activation while cruising at highway speeds.

Timeline of events leading to the award loss

1. 15 December 2025 – pre‑award test: Early COTY judges praised the Model Y for its range (330 mi) and sleek UI.
2. 28 December 2025 – OTA rollout: Tesla pushed the “Vision Plus 2026” update to all 2025 Model Y units.
3. 2 January 2026 – First incident reports: Owner forums (Tesla Motors Club, Reddit r/teslamotors) logged 87 reports of the freeze/cruise‑assist bug.
4. 3 January 2026 – COTY final assessment: During the final road‑test, the glitch caused a safety‑critical “loss of control” flag in the evaluation software, disqualifying the vehicle.
5. 6 January 2026 – Official statement: MotorTrend announced the 2025 Car‑of‑the‑Year award for the Hyundai Ioniq 6 and cited the Tesla software malfunction as a decisive factor.

Technical breakdown of the software failure

• Root cause: A misaligned checksum in the VehicleControl module caused asynchronous data writes to the CAN_TX buffer.
• Affected subsystems:

* Infotainment OS (Linux‑based): UI freeze after 3–5 minutes of streaming.

* Advanced Driver‑Assistance (ADA): ACC and lane‑keeping assist (LKA) temporarily disabled.

• diagnostic evidence:

* Tesla Service Center logs show error code 0xA7B9 (“CAN‑Gateway Overflow”).

* Independent third‑party testers (MotorTrend’s own engineers) recorded a 0.6 second latency spike in the steering‑torque command loop.

How the glitch affected the Car‑of‑the‑Year scoring matrix

Scoring Category	Pre‑glitch Score (out of 10)	Post‑glitch Adjustment	Final Impact
Performance & Handling	9.2	–0.8 (safety flag)	8.4
Technology & Innovation	9.5	–1.5 (software reliability)	8.0
Design & Aesthetics	8.7	0 (unchanged)	8.7
Value for Money	8.9	–0.6 (repair cost risk)	8.3
Overall Composite	9.1	–0.9	8.2

MotorTrend’s scoring rubric mandates a minimum overall score of 8.5 for eligibility. The software glitch dropped Tesla below that threshold, prompting the award committee to re‑evaluate the finalists.

Stakeholder reactions

Tesla leadership

• Elon Musk (CEO) posted on X (Jan 7 2026): “Our engineers are rolling out a fix within 48 hours. Software bugs happen – we learn, we improve.”
• Tesla’s software team announced a “hot‑fix patch” (version 2026.01.01) on Jan 9 2026, restoring full ACC and UI functionality.

industry analysts

• BloombergNEF: “While Tesla’s hardware remains best‑in‑class, this incident underscores the growing importance of OTA reliability for EV awards.”
• J.D.Power: the glitch contributed to a 3‑point dip in Tesla’s 2025 Vehicle Dependability Study (VDS) rating, the first decline as 2018.

Consumers

• A post‑sale survey by Kelley Blue Book (Feb 2026) showed 72 % of Model Y owners expressed “moderate concern” about future OTA updates, up from 45 % in 2024.

Benefits of addressing the issue quickly

• Restored brand trust: The rapid hot‑fix limited warranty claims to under 1 % of the Model Y fleet.
• Improved OTA processes: Tesla introduced a dual‑stage validation that runs a sandbox simulation on 5 % of vehicles before full rollout.
• Data‑driven safety loops: Integration of real‑time telemetry into the Vehicle Safety analytics (VSA) platform enables automatic rollback if anomaly thresholds are crossed.

Practical tips for owners of OTA‑dependent EVs

1. Monitor update notes – tesla’s release notes are now available on the “Service” tab of the vehicle touchscreen.
2. Schedule updates during low‑usage windows – Apply updates overnight when you can quickly confirm vehicle functionality the next morning.
3. Enable “Safety‑First Mode” – A new setting (beta) disables non‑essential UI changes during critical driving periods (e.g., highway cruising).
4. Keep a backup device – Use the Tesla app on a secondary smartphone to verify that the vehicle reports a “healthy” status after an OTA install.

Case study: Hyundai Ioniq 6’s path to the 2025 Car‑of‑the‑Year

• Software reliability: Hyundai’s “Blue‑Link” OTA platform logged a 0.02 % failure rate during the same evaluation period.
• Award criteria match: The Ioniq 6 scored a perfect 9.8 in “Technology & Innovation” thanks to its 48‑hour predictive battery‑thermal management algorithm.
• Key differentiator: Unlike Tesla’s rushed rollout, Hyundai performed a six‑week field‑test with 3,200 volunteer owners before the final update, eliminating major bugs.

Lessons for automakers from the Tesla incident

1. Prioritize OTA safety over feature velocity.
2. Implement staged rollouts with real‑world feedback loops.
3. maintain transparent dialog channels with owners (e.g., live status dashboards).
4. Integrate automated rollback mechanisms that trigger on detection of safety‑critical anomalies.
