GM Parts Club
Spring break is the first long drive of the year for most families, and the vehicle has been sitting through winter. Most spring break breakdowns are things that were already wrong in February.
The Mechanical Checks
Working through a 2023-2026 Cadillac Lyriq as the example, in the order that matters.
Brakes
Watch for a squeal that shows up cold and disappears after two or three stops. Inspect at every tire rotation. Most GM trucks and SUVs go 30,000 to 60,000 miles on front pads depending on how they are used, and towing cuts that hard.
Glass and Wipers
Watch for a washer pump you can hear running with nothing coming out. Blades every six to twelve months. In North Texas, summer heat kills blades faster than winter does.
Cooling System
Watch for a heater that blows cool at idle and warm at speed. GM’s long-life coolant is generally rated for 5 years or 150,000 miles on the first fill and 5 years or 100,000 miles after that. Hoses and the surge tank should be inspected annually once past 80,000 miles.
Electrical and Charging
Watch for a slow crank on the first cold morning of the year. Batteries in Texas heat routinely give up between three and five years. Test annually after year three, before the first cold snap.
Filters and Fluids
Watch for a slight hesitation on hard acceleration with a dirty air filter. Follow the oil life monitor rather than a fixed mileage. Engine air filter every 30,000 to 45,000 miles. Transmission service intervals vary widely by transmission and by whether you tow.
The Cargo Problem
The mechanical side gets all the attention and the cargo side causes most of the actual misery. A loaded vehicle with nothing restraining the load is loud, and in a hard stop it is dangerous.
Cargo Area Liners and Mats
Molded trays with a raised lip for the cargo floor. For anyone who hauls groceries, dogs, sports gear or job site material in an SUV.
Browse genuine GM cargo area liners and mats.
Cargo Nets
Envelope and vertical nets that keep loose cargo from becoming a projectile. Small, cheap, and the recipient will use it every week.
Windshield Sunshades
Folding shades cut to the specific windshield. In Texas this is not a novelty item. It is the difference between a 140 degree dash and a 110 degree one.
Browse genuine GM windshield sunshades.
Roadside and First Aid Kits
GM-branded emergency and first aid kits sized for the cargo area. The gift you hope never gets used. Good for a new driver.

Before You Pull Out
- Tire pressure at the door placard, checked cold, including the spare.
- Wiper blades and washer fluid, because you will need both at the worst moment.
- Battery tested, not guessed at.
- Cabin air filter, if it has been more than a year.
- Everything in the cargo area actually restrained.
