Shop Foreman — Lead technician
Lead technician at an independent shop in the southern US. Mainstream domestic and Japanese vehicles. Pen name protecting current shop employment.
The contributor publishing as Shop Foreman runs the floor at an independent shop in the southern United States. He writes here under this professional identifier instead of his real name because his shop's relationships with parts suppliers, warranty companies, and dealer networks would get awkward if he started publicly grading manufacturers by name. The pen-name arrangement is documented on the About page.
He's been a working technician for more than twenty-five years. ASE-certified across the main categories, plus additional specialty certifications in transmission and engine diagnostics. His shop sees the cars most American families actually drive every day — Silverados and F-150s, CR-Vs and RAV4s, Altimas and Sonatas, Equinoxes and Tahoes. He's got grandkids now, and he says the cars he writes about are the cars his grandkids' parents are driving.
For ProblemsByVin he covers the high-volume mainstream — the platforms that don't fit cleanly into Mark Driver's truck specialty or Frank DeSantis's European focus or Tony Marino's Mopar territory. That means the GM Active Fuel Management lifter problems on the 5.3 V8. The Hyundai/Kia Theta II 2.4 and 2.0T connecting rod failures. The GM 6L80 and 8L90 shudder complaints. The Chrysler 62TE behind the minivans. The Subaru Lineartronic CVT.
What he writes about is what comes back into the shop. The vehicles that were fixed wrong the first time somewhere else. The failure modes predictable enough that he can quote a customer the next repair before the symptoms even start. The patterns repeat across vehicles and across model years, and after twenty-five years of seeing them, he writes about them with the perspective that only comes from doing the work.
No financial relationship with any manufacturer, warranty company, or aftermarket parts retailer. Paid as a ProblemsByVin contributor at a fixed rate per piece regardless of which vehicles he writes about. No incentive structure rewards positive coverage.
