Computer Module Defects — symptoms and safety implications

Engine control module (ECU/ECM/PCM), transmission control module (TCM), body control module (BCM) failures.

Watch for these patterns:

Multiple unrelated warning lights appearing together
Limp-mode events with no specific diagnostic code
Transmission shifting badly with no mechanical issue found
Engine running rich/lean with no fuel-system problem
Module-replacement repairs that don't solve the underlying issue

Safety implications: Module failures can cause sudden loss of power or transmission limp-mode events at highway speeds — both are safety issues.

If the dealer says it's normal and it isn't, that's why we exist.

What counts as a "reasonable number of repair attempts"

State lemon laws use specific repair-attempt counts in their presumption windows — typically 3-4 attempts for the same defect, or 30+ cumulative days out of service, within a window of 12-24 months / 12,000-24,000 miles. Specifics vary by state.

Federal Magnuson-Moss doesn't use a fixed number. MMWA asks whether the manufacturer has had a reasonable opportunity to repair — and reasonable depends on the severity. For safety-critical defects (brake, steering, airbag, fire risk), one or two attempts can be enough. For comfort-feature defects, the bar may be higher.

Two practical things you can do right now:

Keep every repair order. The dealer is required to give you a written repair order — save them all, even the "no problem found" ones. They prove the manufacturer had the opportunity.
Document the symptoms. Photo, video, or audio recording of the defect. Especially helpful when the dealer says they "can't reproduce" it.

This is general information, not legal advice. Take the case eligibility quiz to find out whether your specific repair history supports a claim.

How we use MMWA to push for cash settlements

ECU/PCM/TCM replacements are expensive ($1K–$3K plus programming), and module-supply shortages have stretched some repair times to 60+ days. That delay alone can support a lemon law presumption.

The federal Magnuson-Moss Warranty Act has two features that change the math for computer module defects claims:

Fee-shifting. When the consumer wins, the manufacturer pays the consumer's reasonable attorney fees. That means we can afford to take cases that would be uneconomical on a pure-cost basis.
Covers used vehicles with any written warranty. State lemon laws often exclude used vehicles. MMWA doesn't — if there's a written warranty (CPO, extended warranty, balance of original), MMWA applies.

Our default settlement structure: cash payment for diminished value, you keep the vehicle, manufacturer may pay our fees on top. Never out of your settlement.

How the case works

Same playbook, regardless of which defect drove you here.

Take the quiz

A few quick questions tell you whether your defect pattern likely supports a lemon law or MMWA claim.

We review

Send us photos of your purchase agreement, every repair order, and your warranty booklet.

We demand

We file a formal demand with the manufacturer. Most demands settle without court.

Cash settlement

You keep the vehicle, pocket cash for diminished value. We seek to have the manufacturer pay our fees under federal warranty law.

Computer Module Defect lemon law FAQs

Real questions Computer Module Defect owners ask. Plain English answers.

How many repair attempts before I have a computer module defects case?+

State lemon laws typically require 3-4 attempts for the same defect, or 30+ cumulative days out of service, within a presumption window. Federal MMWA asks whether the manufacturer had a 'reasonable opportunity to repair' — that depends on the severity. Take the quiz and we'll tell you whether your repair count is enough.

What if the dealer keeps writing 'no problem found' on my computer module defects repair orders?+

Save every one of those repair orders. The dealer is legally required to give you a written repair order for every warranty visit — and 'no problem found' on a real defect is itself evidence that the manufacturer can't fix the problem. This is one of the most common patterns in winning MMWA cases.

Does Lemonaid Firm handle used vehicles with computer module defects?+

Yes — if there's any written warranty in place (CPO, extended, original-warranty balance), federal MMWA applies. State lemon laws often don't cover used vehicles; MMWA does.

What's the typical cash settlement for computer module defects?+

Most of our settlements run 15-25% of the original purchase price as a cash payment, plus manufacturer-paid attorney fees under federal warranty law. You keep the vehicle when the math works.

Who do we sue — the dealer or the manufacturer?+

The manufacturer (Ford Motor Co, Toyota Motor North America, GM, Stellantis, Tesla, etc.). The dealer is the manufacturer's authorized service agent under warranty law, but the manufacturer is the warrantor. We file against the manufacturer.

How long does a computer module defects case usually take?+

Most cases resolve within a few months of the initial demand letter. Cases that need to be filed in court take longer but usually settle before trial.

What if I'm outside the state lemon law presumption window?+

Federal MMWA may still apply. MMWA has no fixed mileage or time presumption — it covers as long as there's a written warranty in place. We routinely file MMWA claims on vehicles outside state-law windows.
