About carfailure.com

Something is wrong with your car and you need three things fast: is it safe to drive, what is probably broken, and what should it cost. Most car content answers the second question badly and ignores the other two.

carfailure.com is built around answering all three in that order, starting with the one that actually matters when you are standing next to a car that is doing something wrong.

How the safety verdict works

Every symptom on this site resolves to one of three verdicts: stop driving, fix it soon, or schedule it. That verdict is produced by fixed rules — deterministic pattern matching written in advance — not by an AI model and not by an editor's mood.

Where AI is used to add tailored commentary, it operates under a hard constraint: it can raise a severity level but it can never lower one. If the rules say a flashing check engine light means stop, no model output can soften that. This is a deliberate architectural decision, and it is why safety-critical content on this site behaves predictably.

How costs are estimated

Cost figures are broad ranges for US independent shops covering parts and labour together. They are deliberately wide, because a single national number pretending to be precise would be a lie with decimals. Dealer pricing runs higher; your region, vehicle and parts tier move the range.

The purpose of these numbers is not to tell you what your repair will cost. It is to tell you when a quote is far enough outside the normal range to be worth a second opinion.

How this site makes money

Advertising, and affiliate commissions when readers buy tools we link to. Both are disclosed in full on our affiliate disclosure page.

No shop pays for referrals here. No manufacturer or parts supplier pays for placement. No commercial relationship has ever changed a verdict, a cost estimate, or a recommendation — and where a $25 tool is enough, this site says so rather than steering you to a $350 one.

What this site will not do

It will not walk you through brake, airbag, fuel system, spring or high-voltage repairs. Those can kill you or someone behind you, and no amount of traffic is worth publishing that.

It will not help anyone defeat emissions equipment, disable safety systems, or roll back an odometer.

And it will not pretend to be a mechanic who has seen your car. Everything here is a starting point that makes the conversation with a real technician shorter, cheaper and more informed.
