Hi everyone, a little bit of an update. All the condensation/must from the rear lights seems to have disappeared now. We've covered about 250 miles with the car so far and all good.
Yesterday the car went in for its annual service at the Lexus Exeter, part of the Snows group. The attached is the Hybrid battery health check report, which I found in the pack today. Having always had good experience with Lexus dealers I didn't check anything in the pack that was given to me and they never bothered telling me about it. I got in touch with them today but couldn't get through, so emailed my point of contact.
Have to guys seen anything like this before? Is it something to worry about?
Any help is appreciated.
