You’re driving through San Leandro, and suddenly, your car’s engine feels sluggish. The check engine light pops up. You’re losing power. Chances are, you’ve got a catalytic converter issue. Don’t worry. At Precision Auto Care, we’ve seen it all. Our San Leandro auto repair shop specializes in fixing catalytic converter problems for drivers in the area—and yes, that includes you.
Here are the 7 most common issues and how we fix them.
1. Blocked Catalytic Converter
It’s simple—if your converter’s clogged, your engine can’t breathe. That means reduced performance, poor fuel economy, and eventually, a breakdown. Blockages typically hit older cars like 2001-2005 Honda Accords. At Precision Auto Care, we’ll inspect the converter, clean out carbon buildup, or replace it if it’s too far gone. Does your car struggle on hills? That’s your first clue.
2. Converter Failure from Contaminants
Oil leaks and coolant issues don’t just mess with your engine—they destroy your catalytic converter. This is common in 2011-2017 Ford F-150s. Once oil or antifreeze seeps into the converter, it can’t do its job. You’ll notice more exhaust fumes and maybe that telltale rotten egg smell. At Precision Auto Care, we’ll trace the issue, fix any leaks, and replace the damaged converter. Is your car spewing smoke? Let’s talk.
3. Check Engine Light—Catalytic Converter Code
Seeing the check engine light? It’s probably the catalytic converter, especially if you drive a 2010-2014 Toyota Camry. Modern cars have sensors that monitor your converter’s efficiency. When it’s off, the light flips on. Our team at Precision Auto Care will run a full diagnostic, checking for P0420 codes, and make sure your converter is running clean. That light on your dash isn’t just annoying—it’s a warning. Don’t ignore it.
4. Failed Emissions Test
Failing an emissions test isn’t just a hassle. It’s a legal headache, too. Older models like the 2000-2004 Subaru Outback are notorious for failing emissions when the catalytic converter breaks down. At Precision Auto Care, we’ll run an emissions test, evaluate the converter, and repair or replace it to meet California’s strict standards. Ready for your next smog test? We’ll make sure you pass.
5. Catalytic Converter Theft
It’s a sad truth—catalytic converter theft is rampant in San Leandro. Hybrids like the 2004-2009 Toyota Prius are hot targets because they contain precious metals like platinum. Thieves leave you with a loud, gut-wrenching roar when you start your car. Precision Auto Care offers replacement converters and anti-theft devices to protect your vehicle from future hits. Have you been a victim of theft? We’ve got your back.
6. Rattling Noises from a Broken Converter
Hear a metallic rattle under your car? That’s a sign your catalytic converter is damaged inside. This happens when the converter overheats, causing parts to break loose. Models like the 2006-2012 Nissan Altima are known for this. At Precision Auto Care, we’ll check for any loose parts, remove the converter if needed, and replace it. Don’t let that rattle turn into a bigger problem.
7. Excessive Heat from Catalytic Converter
Converters are designed to run hot, but sometimes they overheat and cause engine damage. This issue is common in vehicles like 2008-2013 Chevy Tahoe. The fix? Precision Auto Care will inspect the entire exhaust system for blockages or engine misfires that lead to overheating. We’ll replace the damaged converter and make sure your engine is running smoothly again. Is your engine running hot? We can help.
