Holden Captiva Problems

It is worth fixing, you will only have more trouble if you don’t. Cost depends on the engine. If it’s a V6 it could cost as much as $3000, a 4-cylinder less.

The computer is getting a message that the engine is overheating. You have replaced the temperature sensor, so check the connections, and the wiring looking for a wire that might have shorted out.

It needs to be fixed, it’s worth very little if you don’t repair it. There’s no reason to believe that you won’t get many more years out of it if you do have it repaired.

The 2012 Holden Captiva LX was AWD and had a 4-star ANCAP rating.

Injector wear is prevalent on common-rail diesel engines with the high fuel pressure and rapid cycling. A diesel mechanic should be able to check the injectors for leakage.

The cost including a new alternator should be $1000 to $1200.

It’s most likely the battery in the key needs replacing. Have you tried the spare key?

Never let things slide if you feel your car has a problem. Pursue a solution until you are satisfied you have the answer. It’s not a good idea to miss services, particularly on cars with turbochargers. Keeping a fresh supply of oil is the key to trouble-free motoring with turbos. There’s every chance the turbo was faulty when you first noticed it, and having missed a service you probably contributed to the failure. There’s probably not a lot you can do, except to pay for the repairs.

Take it to a Holden dealer or an auto electrician and have the sensor replaced.

It’s not unusual for mechanical damage to occur in a crash, and most insurance companies cover that damage when it can be shown that it was caused in the crash. Your problem seems to be that your insurance company is saying the mechanical damage wasn’t the result of the crash. Get another opinion from an expert and once you’ve got that you can decide if you want to pursue your claim.
