Are they actually replacing the oil lines? My understanding (and this is for the second of the 2 oil line recalls) is that the lines were rubbing somewhere and Lotus was looking at some form of protection for them.
It states "It has been determined that engine oil leaks have occurred from an oil cooler hose specifically used on the supercharged engine in a small number of USA specification vehicles manufactured between September 2010 an September 2011."
“Subject: Part 573 Recall Notice #13V-314 – Follow-Up Report
This information is submitted in accordance with the requirements of Title 49 Part 573 of the Code of Federal Regulations. Lotus Cars Limited would like to advise the Administrator of further information that has become available relating to Recall Notice 13V-314.
Description of Defect:
There have been two incidents where an engine oil cooler hose has ruptured resulting in oil loss. A lack of clearance between the hose and the edge of a composite bulkhead may result in abrasion to the hose due to the natural movement of the engine (see Annex C).
It has been established that in the event of hose failure, engine oil may be ejected onto the road surface and/or rear wheels which could cause a reduction in vehicle control and potential engine failure. There may also be a loss of oil into the engine bay area resulting in an increased risk of fire. This could result in a crash, serious injury or fatality.
The pipe in question is a Lotus designed part, manufactured by Delta Aircraft Services and is used exclusively on Evora supercharged, manual gearbox variants.
The part is now obsolete following a system design change implemented with the introduction of the Evora auto gearbox variant.
Proposed Remedial Program
Lotus can now offer an oil cooler hose kit which is fitted as a direct replacement for the original hose. The revised hose dimensions ensure that the rubber section of the assembly can no longer make contact with the chassis or bulkhead panel.
Number of Vehicles Potentially Containing the Defect
80 vehicles in the United States are affected by this recall:
2011MY Evora S 80
Percentage of Vehicles Actually Containing the Defect
The percentage of vehicles estimated to actually contain the defect is 100%.”
I got my letter today too. It says estimated labor time is 3 hours. In the past, I've found Lotus' time estimates to be excessively optimistic. Whoever gets this done first, please report back as to what the work entailed.
