Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 16,000 mi; spark plugs every 96,000 mi; coolant at 160,000 mi. The big-interval services (at 160,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

Federal data positions the 2023 model year at the peak of the current generation’s reliability curve, registering 75 complaints and 9 recalls—up from 2022’s 66 complaints and 6 recalls, and significantly higher than 2024’s 21 complaints and 6 recalls—while Technical Service Bulletins declined modestly to 394. Electrical system issues constitute the largest complaint category with 25 reported incidents, followed by visibility and wiper defects at 12, though the federal records do not specify root causes for these failures; notably, the model year recorded zero crash- or fire-related complaints. The sharp improvement in 2024 metrics suggests manufacturer corrections were implemented post-2023, implying the 2023 model carries unresolved production vulnerabilities specific to that year. Consequently, buyers should view the 2023 model as the least favorable year of this generation to purchase used, prioritizing either the 2024 refresh or accepting the marginally lower complaint volume of the 2022 predecessor.
