Description of the problem | Lexus isf, year models 2008-2014, are affected by a valley plate leak due to the fact that toyota/lexus utilized the improper sealant and used the improper amount, leading to the heat exchanger leaking coolant once the original, inadequate sealant begins to disintegrate. This could cause a condition where the engine could fail and someone could get hurt. This issue is very prominent in the community (every lexus facebook group and forum has documented this information) - most isfs develop this under 100k miles. Furthermore, all isfs will eventually have a cracked rh manifold on the #8 runner. This can cause a fire hazard in addition to carbon monoxide poisoning. My 2008 isf has been leaking coolant for about 15k miles, progressively getting worse (inspected every oil change). In addition, i have to start topping of the coolant every week. Lexus dealer quoted this repair at almost $2000. |
