2024 Cadillac Lyriq Lemon Law Case Study — Texas
A Cadillac Lyriq That Braked on Its Own in the Rain — and a Screen Problem GM Admitted It Couldn't Fix
Our client purchased a 2024 Cadillac Lyriq Lux-2 — a premium electric SUV from General Motors' luxury brand — in Texas in October 2024. Within months, the Lyriq began exhibiting a series of compounding defects that sent it back to the dealer again and again. By the time the case was closed, the vehicle had been in for service seven times, logged 36 cumulative days out of service, and had a central screen failure that GM's own engineering team acknowledged they were still working to understand.
Most concerning: starting at the second repair visit, the Lyriq's automatic braking system engaged on its own in wet weather — with the vehicle applying the brakes autonomously during normal rain-driving conditions. The problem was documented across two consecutive service visits. Despite this, the dealer's only explanation was that the front license plate frame might be "4–6 mm too thick" — an answer that did nothing to prevent the vehicle from unexpectedly braking again.
Easy Lemon built a case around both the safety defect angle — under Texas law, only 2 repair attempts are required for a safety defect — and the cumulative 36 days out of service exceeding Texas's 30-day statutory threshold. The result: a full buyback by General Motors.
What Went Wrong
- Recurring blank display screen: The Lyriq's central touchscreen and instrument cluster display went completely black while driving — a recurring defect documented across visits 1 through 7. GM engineering was notified and was actively investigating. At the final visit (visit 7), no software update was available and the issue remained unresolved
- Autonomous emergency braking in rain: The vehicle's automatic braking system engaged without driver input during normal rain-driving conditions on at least two documented occasions (visits 2 and 3). The dealer hypothesized the front license plate frame was causing sensor interference — but no definitive repair was made, and no test was performed to confirm the fix
- A/C compressor bracket physically twisted: At visit 2, a technician found the A/C compressor mounting bracket had become physically twisted — a structural failure on a vehicle purchased just months earlier. GM engineering was working on a fix expected in "early 2026" — well outside any reasonable repair timeline for a near-new vehicle
- Vibrating noise from front with heater on: A recurring vibration from the front of the vehicle triggered by heater operation was documented at visit 6 — GM engineering was again cited as investigating, with no solution available
- ABS system warning and battery discharge: At visit 1, a "Service ABS Brake System" warning appeared and the vehicle's battery was found completely discharged. The battery was recharged, but no root cause for the discharge was identified
- Radio static and screen unresponsiveness: In addition to blackout events, the display emitted static sound and was unresponsive to touch — requiring full radio replacement at visit 5. Despite the replacement, the blackout recurred at visit 6
Seven Visits in Five Months — A Screen GM Couldn't Fix, Brakes That Fired Themselves, and a Twisted Compressor
Visit 1 — January 28–29, 2025 (2 Days): Blank Screen, ABS Warning, Dead Battery
On the vehicle's first service visit, our client reported a completely blank dashboard screen. Technicians also found a "Service ABS Brake System" warning active and the vehicle's battery completely discharged — requiring a full recharge. The side detection sensors were triggering false alerts. The screen issue was attributed to a calibration reprogramming need. The ABS battery discharge root cause was not identified.
Visit 2 — February 24–26, 2025 (3 Days): Self-Braking in Rain, Twisted Compressor Bracket, Screen Still Blank
Our client returned with three new concerns. First: the radio screen was intermittently going completely black while driving, with the cause listed as unknown — GM engineering was notified and investigating. Second: a technician found the A/C compressor bracket was physically twisted; GM engineering was working on a fix expected in early 2026. Third — and most alarming: the vehicle was braking on its own when it rained. The technician could not duplicate the autonomous braking but noted the front sensors might be overly sensitive. No repair was made for the self-braking defect.
Visit 3 — March 3–5, 2025 (3 Days): Self-Braking Continues, No Screen Fix Available, Compressor Still Unresolved
The vehicle returned with the same constellation of issues. The autonomous braking in rain was documented again. This time the technician offered to remove the front license plate to "re-evaluate" whether the frame was causing sensor interference — but the plate remained on the vehicle and no follow-up test was performed. The screen blackout continued, with no software fix available from GM. The compressor noise continued, with GM engineering's estimated resolution date still listed as "early 2026."
Visit 4 — March 14–17, 2025 (4 Days): Radio/IPC Screens Still Blank, Programming Attempted
The radio and instrument panel cluster (IPC) screens continued to blank out intermittently. Technicians performed radio programming in an attempt to address the recurrence. The vehicle was returned to the client, but the programming fix did not hold — the same issue returned within days, prompting the next visit.
Visit 5 — March 18–21, 2025 (4 Days): Entire Radio Unit Replaced — Defect Persisted
With programming having failed to resolve the recurring blackout, technicians escalated to a full radio replacement. The complete radio unit was swapped out. The vehicle was returned. The screen went black again on the very next visit. Replacing the hardware component did not resolve the underlying defect — a significant finding suggesting a deeper systemic issue within the vehicle's electrical or software architecture.
Visit 6 — March 22–April 8, 2025 (18 Days): Blackout Returns After Radio Replacement, New Vibration Defect Found
Our client returned the vehicle almost immediately after the prior repair visit, reporting the same blackout display. Despite the full radio replacement, the screen was still blanking while driving. Technicians could not duplicate the concern during inspection. A new defect was also documented: a vibrating/buzzing noise from the front of the vehicle when the heater was on — also attributed to an open GM engineering investigation with no available fix. This single visit lasted 18 days — the longest single repair stay in the case, and by itself exceeding half of Texas's 30-day cumulative threshold.
Visit 7 — May 19–20, 2025 (2 Days): Screen Still Black, No Update Available, Case Closed via Buyback
The seventh and final service visit confirmed what the prior six had established: the screen blackout remained an unresolved defect, no software update was available, and GM had no timeline for a fix. Easy Lemon's legal demand was filed after this visit. With 7 repair attempts, 36 cumulative days out of service, and documented safety concerns across multiple visits, General Motors agreed to a full buyback. The settlement was finalized in May 2025 — approximately seven months after purchase.
Why This 2024 Cadillac Lyriq Qualified as a Lemon in Texas
This case met the Texas lemon law thresholds on multiple independent grounds — including the accelerated safety-defect standard, the standard repair-attempt threshold, and the out-of-service day count.
- Safety defect — 2-attempt threshold exceeded: Texas Occupations Code § 2301.605 provides that when a defect is likely to cause serious bodily injury or death, the threshold drops to just 2 repair attempts. The Lyriq's autonomous emergency braking system engaged without driver input during rain on at least two documented visits (visits 2 and 3). A vehicle that brakes unpredictably at highway speeds in wet weather qualifies as a safety-critical defect — and the 2-attempt threshold was fully met
- Standard threshold — 4+ repair attempts: Beyond the safety defect argument, the recurring screen blackout alone was documented across all 7 visits. Programming, a full radio hardware replacement, and GM engineering involvement all failed to resolve it. This satisfies the standard Texas lemon law threshold of 4 or more repair attempts for the same defect many times over
- 30+ cumulative days out of service: Texas lemon law provides an independent ground when a vehicle has been out of service for 30 or more cumulative days due to repair. This Lyriq accumulated 36 cumulative days — exceeding the statutory threshold by 6 days, with the single 18-day visit at repair 6 being the primary driver
- GM engineering admission of no fix: Multiple repair orders documented GM engineering's awareness of the defects — and their inability to fix them within any reasonable timeframe. "No software update available" and "fix expected early 2026" statements in the repair orders are powerful evidence that the manufacturer could not repair the defect within a reasonable number of attempts
- Federal Magnuson-Moss Warranty Act: GM's repeated failure to repair the screen, braking, and compressor defects also constitutes a breach of the vehicle's express warranty under federal law, providing an additional independent claim basis alongside state lemon law
How Easy Lemon Fought for Our Client
Free Case Evaluation
We reviewed all seven repair orders and evaluated the case against Texas lemon law thresholds. We immediately identified both the safety defect angle (autonomous braking, 2-attempt threshold) and the cumulative days out of service approach — giving us multiple independent grounds for a strong legal demand.
Documentation & Case Construction
We mapped every repair visit, each documented defect, and the GM engineering acknowledgments against the applicable Texas statute thresholds. The repair orders were particularly useful: GM's own technicians had recorded that engineering was "investigating" the screen issue with no fix available — effectively admitting in writing that the defect exceeded their ability to repair within a reasonable timeframe.
Formal Demand to General Motors
We filed a formal legal demand against General Motors LLC under the Texas Lemon Law (Texas Occupations Code Chapter 2301) and the federal Magnuson-Moss Warranty Act — citing the safety defect, 7 repair attempts, 36 days out of service, and the documented GM engineering admissions. The safety defect claim was front and center given its 2-attempt threshold advantage.
Buyback Negotiated — No Arbitration Required
Easy Lemon negotiated directly with GM's legal team without the need for MVDTF arbitration proceedings. With 7 documented repair attempts, a safety defect on record, and the statutory day count exceeded, GM agreed to a full repurchase of the vehicle. The buyback was structured under the standard Texas lemon law formula: purchase price minus a use offset calculated from miles driven before the first repair.
Settlement Finalized — May 2025
Our client received a full buyback within approximately seven months of purchase — one of the faster resolutions in a multi-visit case, made possible by the strength of the safety defect documentation and GM's own engineering admissions in the repair records. The vehicle was returned to General Motors, and our client received a full refund adjusted for statutory mileage offset under Texas law.
