Toyota Auris2017

Known issues

• Hybrid battery capacity loss after 150,000+ miles, though still maintains 80%+ capacity in most cases
• 12V auxiliary battery may require replacement around 5–7 years due to constant drain from hybrid system management
• Water ingress into rear lights causing condensation and electrical gremlins, particularly in 2015–2017 models
• CVT transmission occasional shudder during low-speed driving or stop-start traffic, usually software-related
• Brake fluid contamination (moisture absorption) requiring flushes more frequently than conventional cars due to regenerative braking system cycling
• Engine carbon build-up on direct-injection petrol engine if driven primarily at low speeds; infrequent motorway use can worsen this

Good for

• Exceptional fuel economy (45–55 mpg real-world with mixed driving) and low road tax due to CO₂ emissions
• Bulletproof reliability with Toyota hybrid system proven over two decades; minimal major failures expected
• Low maintenance costs overall—no oil changes as frequent, long brake pad life due to regenerative braking
• Quiet, smooth driving experience with excellent torque delivery from electric motor at low speeds; ideal for urban commuting
