Our catalog currently lists 33 electrical parts for the 2014 Acura RLX across 7 subcategories and 15 brands, covering both the 3.5L V6 and the 3.5L V6 ELECTRIC/GAS. Each part is matched to the engine(s) it fits.
Do electrical parts differ between 2014 Acura RLX engines?
Yes. Every electrical part on this page is engine-specific. Each row shows which engine(s) it fits — use the filter at the top to hide the rest. If you're unsure which engine you have, check the emissions label under the hood or the 8th character of your VIN.
What are the signs of electrical problems on a 2014 Acura RLX?
Common symptoms include slow cranking on cold mornings, a battery light that flickers, dim lights at idle, or a check-engine code pointing at a sensor circuit. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.
What should I replace at the same time?
Where labor overlaps, clean or renew the battery terminals and grounds with any charging-system repair.
What do the market flags (US, CA, MX) on each part mean?
They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2014 Acura RLX was originally sold in the US, the safest choice is a part marked for the US market.
How do I make sure a part fits my 2014 Acura RLX?
First match the engine — each row shows which engine(s) the part fits. Then test before replacing — a failed alternator and a bad ground can look identical, and sensors are frequently condemned for wiring faults. The notes column carries position and trim qualifiers where they apply.
