📖Chevrolet Montana III: reinventing the unibody pick-up as a refined lifestyle crossover

Arriving in 2023 on General Motors' modern GEM architecture, the third-generation Montana represents a radical departure from its utilitarian predecessors. Transformed into a double-cab compact pick-up with sophisticated SUV road manners and an innovative Multi-Flex cargo bed, it targets both lifestyle buyers and commercial operators. Rigorous Chevrolet Montana maintenance is vital to safeguard its downsized turbocharged powertrain and onboard technology.

Under the bonnet sits a 1.2-litre three-cylinder turbocharged Flex engine paired with either a six-speed manual or six-speed automatic transmission. This advanced power unit relies on a wet timing belt running in engine oil, which makes strict adherence to GM Dexos1 engine oil specifications absolutely mandatory. Using incorrect oil viscosities or postponing oil changes causes belt degradation, leading to loosened rubber particles clogging the oil pickup strainer and causing catastrophic oil starvation.

Owner notes

The reassuring points, known weak spots and deadlines you should not let slip.

Reassuring points

Reliability

Modern GEM platform delivers passenger-car ride comfort, quiet cabin refinement, and secure high-speed stability.
The 1.2 Turbo Flex engine provides lively acceleration and impressive fuel efficiency, especially with the 6-speed automatic.
Innovative Multi-Flex cargo bed design with modular compartments and modular tonneau cover provides exceptional utility.

Chronic weak spots

Keep an eye on

1.2 Turbo three-cylinder: strictly verify oil specification and change history to prevent wet timing belt degradation.
Oil pickup strainer: inspect for debris accumulation during scheduled sump inspections or if low oil pressure warnings flash.
Six-speed automatic gearbox: test for shift hesitation or jerky low-speed engagement in urban stop-start traffic.
Multi-Flex cargo bed: check tailgate sealing, electrical lock mechanisms, and tonneau cover drains for water ingress.
Onboard electronics: test the 8-inch MyLink touchscreen, digital instrument cluster, and rear parking camera for software stability.

Critical deadlines

Do not miss

Engine oil and filter renewals using certified Dexos1 synthetic oil must be performed strictly on schedule to preserve the wet belt.
Any low oil pressure warning or unusual valvetrain rattle must be investigated immediately before engine seizure occurs.
Automatic transmission fluid renewals and Multi-Flex tailgate seal lubrication should be kept up to date for lasting reliability.
