What Is a Multi-Point Inspection?

A multi-point inspection, often shortened to MPI, is a full walk-around and under-the-hood check that a technician performs during a service visit. It covers tires, brakes, fluids, filters, belts, hoses, lights, and the components underneath the vehicle, and it flags anything worn before it turns into a breakdown or a bigger repair bill. Most dealerships build it into every visit, whether you're in for a quick oil change or dropping the car off for something else entirely.

What the inspection actually covers

A thorough inspection is broken into sections so nothing gets skipped: tires and brakes, interior and exterior items, everything underneath the vehicle, and everything under the hood. A technician works through a written checklist for each section, and most shops don't charge extra for it when you're already in for other service. Technicians follow the same checklist every time, in the same order, so a worn belt or a leaking hose doesn't get missed just because the shop was busy that day.

Tires and brakes

Every tire is checked for correct pressure, tread depth, and any visible damage like bulges or embedded debris. Tread is measured at several points across each tire, since uneven wear often signals an alignment or suspension issue instead of a bad tire. Front and rear brake pads, rotors, hoses, and calipers are inspected for wear, since the front and rear axles rarely wear down at the same pace.

Interior and exterior items

Wiper blades, exterior lights and turn signals, the horn, the parking brake, and cabin air filters all get checked here. These are small parts, but a burned-out signal bulb or a torn wiper blade is exactly the kind of thing that's easy to miss until you actually need it. The horn and parking brake rarely fail on their own, so a technician checks them at every visit instead of waiting for something to seem off.

Under the vehicle

With the car raised, a technician checks the shock absorbers and suspension components, steering parts, the exhaust system, the drive shaft, and fuel lines. They also look for leaks around the transmission, differential, transfer case, and engine. A slow leak here is often the first sign of a problem that hasn't shown up on the dashboard yet. Fuel lines and the exhaust system are checked for rust or physical damage too, since a small leak underneath the car is far easier to spot on a lift than from the driver's seat.

Under the hood

This is where fluid levels, the engine air filter, drive belts, coolant and air conditioning hoses, and the battery all get checked. Drive belts are checked for cracking and glazing, and hoses are squeezed to check for a spongy or brittle feel, since either one can fail with little warning. A weak battery in particular tends to fail with little warning too, so a load test during a routine visit can catch it before it leaves you stranded in a parking lot.
