Vauxhall Corsa FIRE RISK

Saw some news report on the telly today, about Vauxhall cars bursting into flames... didn`t hear the commentary... just found this on our favourite DAILY MAIL..


Up to 865,000 Vauxhall Corsas may have a similar wiring fault to the one that forced a recall of a quarter of a million Zafira models, it was claimed last night.

Experts fear that all Corsa D and E models built since 2006 are a potential fire risk, with dozens of motorists reporting flames seeping through their dashboards.

The Corsa, which is Britain's second best-selling car, is said to have heater wiring susceptible to heat damage, like the Zafira.

Re: Vauxhall Corsa FIRE RISK

It has been a known issue for months, from what I can make out, but Vauxhall are in denial.

It seems to be the heater fan dropper resistors at the root of the problem. These are often mounted in the fans air flow to keep them cool, which in modern cars is a plastic duct. The resistors generate most heat, when the fan is running on the lowest speed, which means they get least cooling when they most need it. 

Only the more basic models without aircon, use resistors for speed control, the less basic models use PWM speed control which generates much less waste heat.

Re: Vauxhall Corsa FIRE RISK


If you are correct and I have no doubt you are, one has to ask why this was allowed to happen in the first place.

The company must employ enough design engineers who should not have missed such a simple fault ?

At one time some things were tested to destruction so they could identify a safety limit that could not be exceeded in normal operation.

Not only will this cost the company money but it will also damage their reputation

Any sensible designer would have mounted the resistor on a metal surface like part of the body shell so it could then dissipate the heat generated away safely plus blow the fuse if it ever suffered a short circuit.

But as we all know, the north american big three are as bad for "That'll do" as British Leyland were, so no sensible designers anywhere, just "That'll do"... Funny
