Known problems
- Critical
Power-seat motor overheating (park-outside recall)
Symptoms: front power-seat slide motor can overheat if the switch sticks, with a fire risk when parked
What to do: Check recall status by VIN and follow the interim guidance to park outside and away from structures until the remedy is done.
- Critical
Tow-hitch harness fire risk
Symptoms: electrical short in a factory 4-pin tow-hitch harness module; potential to smolder or catch fire even when parked
What to do: Check recall status by VIN and have the recall remedy performed; this was a formal safety recall on early build years fitted with the genuine tow-hitch harness.
- Worth watching
High-pressure fuel pump stalling
Symptoms: engine stalling or hesitation from a failing high-pressure fuel pump
What to do: Check recall/campaign status by VIN; have any stalling or hard-start symptoms diagnosed rather than ignored.
- Good to know
Windshield cracking and costly ADAS replacement
Symptoms: windshield cracks reported by many owners; replacement is expensive because of embedded ADAS sensors that require recalibration
What to do: Largely a cost/annoyance issue rather than a safety defect; a windshield with camera-based driver-assist must be recalibrated after replacement.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 7,000 mi (12,000 km) or 12 months | halve under severe/towing/short-trip use |
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Air filter | every 28,000 mi (45,000 km) | — |
| Spark plugs | every 62,000 mi (100,000 km) | iridium plugs on the naturally-aspirated V6 last a long service life |
| Brake fluid important | every 24 months | — |
| Timing chain inspection | — | Lambda II V6 is chain-driven — inspect for noise rather than scheduled replacement |
Manufacturer-declared fuel economy
| Engine | City | Highway | Combined | Cycle |
|---|---|---|---|---|
| 3.8 GDI V6 (Lambda II) ON / 1st gen · 2020–present | 19 mpg (12.1 L/100 km) | 25 mpg (9.4 L/100 km) | 22 mpg (10.9 L/100 km) | EPA |
Lab-cycle figures, each shown with the cycle it was measured under — the same car under WLTP, NEDC, EPA or JC08 can differ by up to 20%. Real-world consumption typically runs 15–30% above the declared number, and that gap is normal, not a fault.
