Subaru Forester Overheating: What Owners Report
43 of the 5,170 owner complaints NHTSA has for 2008–2024 Forester models describe overheating. Here is which years and systems show up most, what owners say, what to check first, and when a mobile mechanic can fix it where the car sits.
NHTSA data pulled September 2026.
Pull over when it is safe, turn the engine off and let it cool. Never open the radiator or coolant cap on a hot engine – the coolant is under pressure and can burn you.
Which Forester years report it most
Reports peak with the 2019 model year (9). A year with more cars on the road usually has more reports, so use this to know what to ask, not to rank years.
What else these reports mention
Owners filing these complaints most often also named the engine and transmission and drivetrain – usually where a mechanic starts looking.
| System named | Reports | Mobile mechanic? |
|---|---|---|
| Engine | 19 | Diagnose first |
| Transmission and drivetrain | 12 | Usually a shop |
| Electrical system | 7 | Often in the driveway |
| Driver-assist systems | 4 | Dealer or recall |
| Throttle and cruise control | 3 | Diagnose first |
| Brakes | 3 | Usually on the spot |
What Forester owners describe
“I assumed this would have been possibly some type of overheating issue, but upon inspection I discovered it was engine oil dripping onto the exhaust heat shields and was burning off.”
“Traction control, cruise, transmission overheat, check engine all became illuminated.”
“Thinking it was an overheating issue, I stopped the car and waited a while.”
“I was told that if it was not repaired that the catalytic converter would overheat and valve damage to the engine would occur.”

| Reported | Campaign | Model years | System | What can happen |
|---|---|---|---|---|
| 2023-10 | 23V723000 | 2024 | Engine and cooling | Leaking coolant can contact a hot exhaust pipe, increasing the risk of a fire. |
| 2019-12 | 19V856000 | 2019 | Engine and cooling | An unexpected loss of power while driving can increase the risk of a crash. |
| 2016-10 | 16V738000 | 2009–2013 | Electrical system | If the air injection pump overheats, it may melt and increase the risk of a fire. |
| 2016-03 | 16V162000 | 2015–2016 | Engine and cooling | An engine stall increases the risk of a crash. |
| 2008-09 | 08V460000 | 2009 | Engine and cooling | Vibration would occur while driving and, over time, could eventually result in cracking the pipe which would allow oil to leak. |
Safety recall repairs are done free by the brand's dealers. A mobile mechanic cannot do recall work. Enter your 17-character VIN at nhtsa.gov/recalls to see open recalls on your exact car. "Park it" means NHTSA and the maker say not to drive the vehicle until it is fixed.
What to check first
- Once the engine is cold, check the coolant level in the overflow tank.
- Look under the car for green, orange or pink puddles – a coolant leak.
- Check whether the radiator fan runs when the engine is warm and the A/C is on.
- Watch for white smoke from the exhaust or a sweet smell, which can mean a head gasket problem.

Can a mobile mechanic fix it?
Often. Thermostats, hoses, radiators, fans, water pumps on many engines and coolant leaks are common mobile jobs. A blown head gasket or a cracked engine block needs a shop.
