Should you keep it?
Keeping vs replacing your GMC Sierra
- Cheapest year to keep: 2014, at about $5,791 a year.
- Most repair-heavy complaints: 2024, based on NHTSA owner complaints about the engine, transmission, electrical and fuel systems compared with similar cars that year.
- Fewest repair-heavy complaints: 2013.
- Older isn't always cheaper: value lost shrinks as a car ages, but maintenance and repairs grow, from $721 a year for a 2025 to $2,045 for a 2011.
A paid-off car is usually the cheapest car you can drive, even with repairs: a replacement starts losing value the day you buy it and comes with tax, fees and often a loan. Switching tends to pay only when repairs get large and frequent, or a much more efficient car cuts fuel costs enough. Keep or Switch compares your GMC Sierra against any replacement, including the costs of switching.
