Frequently Asked Questions

What is the first thing to check when the check engine light comes on?

• Inspect the gas cap: a loose or damaged cap is a common cause on a 2024 Alfa Romeo Tonale and can trigger an EVAP code.
• Look for obvious alerts on the dash and check oil and coolant levels; addressing simple items often resolves the light quickly.
• If the Tonale requires premium unleaded fuel, confirm the correct fuel was used to avoid sensor readings caused by improper fuel.
• For peace of mind and to protect warranty coverage, have any necessary diagnostic or repairs performed at Herb Chambers Alfa Romeo of Millbury by factory-trained technicians.
• Scheduling service with us can provide immediate and long-term savings versus delaying repairs, and warranty repairs must be completed at a certified dealership.

What does it mean when the check engine light comes on in a 2024 Alfa Romeo Tonale?

• It signals that the vehicle’s onboard diagnostics detected an emissions, sensor, or engine performance issue; codes are stored in the car’s OBD-II system.
• Causes range from a loose gas cap or faulty oxygen sensor to misfires or catalytic converter concerns; the stored code directs the next steps.
• Ignoring the light can lead to reduced fuel economy, higher emissions, and more expensive repairs down the road; dealer service helps avoid those costs.
• Our certified technicians use Alfa Romeo factory tools to diagnose issues accurately, often delivering lower overall cost and better long-term reliability than delaying or using non-certified shops.
• Remember: repairs covered by warranty must be performed at a certified dealership to maintain coverage.
