Estima Hybrid

Recommended Posts

I’ve been looking around for a replacement for my old Previa and have (more or less) settled on an Estima. Reading various reviews, the issue of maintenance/repair of the Estima hybrid system was flagged as potentially problematic.

It was stated that UK Toyota dealers would be unlikely to assist on the basis that (i) the Estima hybrid uses different technology to that found in other Toyota hybrids in the UK and (ii) they are unlikely to have “specialist tools” required to locate/repair a problem.

I’m no mechanic/engineer, so I wondered if any Estima owners could provide some opinion.

Many thanks.

Welcome Mike...can't see why a JDM model would be my different to a UK/Euro one..?..but I have no knowledge of hybrids so I can't be definitive.

I'm sure "Paulscarbs"...member here....can enlighten you further as he has a Hybrid Estima.

I just missed out on a superb petrol Estima a few days ago -2013; X spec; 40k miles; absolutely spotless inside and out. I’d had it checked mechanically, but another guy arrived at the dealer with a bagful of cash (literally) and bought it before I could get back with a deposit.

That's a shame, Mike...sounded good... I'm happy with my V6 "beast" though.

I've had it over 2 years now and still love it...it is such a pleasure to be in it...and drive it.

Hope you find what you want.

Hi just purchased a 2008 estima hybrid e four x all been good but just this morning pulled away and the dashboard lights came on. And only had power from the petrol engine plus the car was not regenerating the Battery on brakeing I had seen on YouTube a guy disconnected the Battery then reconnect problem gone for now but still would love to know the cause the first time

If  similar problems happen on Prius or hybrid Auris, then this can be caused by the traction Battery cooling fan being clogged up with dust and/or pet hairs.  This allows the Battery to go over-temperature, the ECU is constantly checking this temperature, and will stop using the traction Battery if it gets overly hot. 

Was it hot where you were yesterday? The weather has been lovely down here -  this situation is more likely in hot weather. (The 'cool' air is drawn by the fan from inside the passenger cabin on the Prius/Auris, next to the rear seat, perhaps this is similar on yours?)

Roads with lots of gradients and stop/start driving will generate heat in the batteries, if the fan is blocked it can all add up to the hybrid system shutting down.

Cleaning the fan should be straightforward, perhaps a forum member has done this?  There is generally no lasting damage to the batteries from this happening on Prius/Auris, (if it is this!), but the cooler the batteries run then the longer they will last.

This video identifies some of these parts on another Toyota hybrid, the actual components are not particularly different across different models, unless yours is the exception! :-

Without an error code being pulled of via an OBD2 reader then this is all just guesswork.

If you were looking to keep the car, given it's rarity, it might be worth investing in an OBD2 bluetooth dongle (£10 - £30) and seeing if using Hybrid Assistant app (it's free) for use an android phone, works with your Estima.  This would allow you to check Battery temperatures and general hybrid operation, and/or a 'cracked' copy of Toyota Techstream and cable off eBay or Amazon, (use with a laptop) (£15- £25).  The latter is basically the same as the dealer's diagnostics.  The OBD2 ELM327 dongle can be used with any modern car, not just hybrids.

There are topics on this forum about these.
