Bought a 2014 Camry Hybrid with 304k miles for $3,600 after totaling my 2016 Camry. Gas prices pushed me toward a hybrid and honestly I’m saving a ton commuting.
I’m not a car person at all. Clean title, clean Carfax, drove well, interior was clean, so I bought it without getting a full inspection. So far it’s been good other than a tire pressure light that went away after adding air.
Realistically, how worried should I be about the hybrid battery at this mileage? Could it still last awhile or should I already be preparing for replacement?
Also, any tips on what I should or shouldn’t do to keep a very high-mileage Camry Hybrid alive as long as possible? Signed anon
