Why the school run matters
Upper Coomera's schools include Coomera Springs, Highland Reserve, Upper Coomera State College, Assisi Catholic College, Coomera Anglican College and Saint Stephen's College, and most of the suburb's newer schools opened between 1996 and 2009. If your week is a loop of drop-offs, shops and home, the car rarely gets far.
RACV says trips under 20 minutes don't give the alternator enough time to recharge the battery, and RACQ adds that stop-start systems put extra stress on it. A battery that cranks slowly is telling you something.
Diesel SUVs have the same problem in a different place. RACQ says low-speed, stop-start driving is the most common cause of diesel particulate filter trouble, and the RAA suggests a weekly 20 to 30-minute run at highway speed. From Upper Coomera, the M1 is on the doorstep.
Upper Coomera's roads
Tamborine-Oxenford Road
State Route 95 runs through the suburb and on up to Tamborine Mountain, 22.2 km from the motorway at Oxenford by a winding route. A weekend drive up there does the battery good and works the brakes hard on the way down.
Exits 54 and 57
Exit 54 (Foxwell Road and Days Road) lists Upper Coomera among its destinations, and Tamborine-Oxenford Road meets the M1 at exit 57, on the Oxenford side of the Coomera River.
If it were our school-run car
We'd have the battery tested at every service once it's past three years old, and if it's a diesel, we'd make the weekly motorway run a habit rather than an afterthought. Both are small things, and both head off a no-start in the school car park.
