McLaren MP4-12C — Recalls, Reliability, Specs & VIN Decoder

The contact owns a 2013 McLaren MP4-12C. The contact stated that mold was developing in the lens covering the headlights, causing the headlights to be foggy. The contact stated that the failure was affecting his vision of the roadway while driving and was causing a glare for oncoming drivers. The vehicle was taken to the dealer, where it was diagnosed that the headlight housings needed to be replaced. The manufacturer was notified of the failure and covered the replacement of the headlights housing; however, the failure persisted, and the headlight housings were replaced with the same model of headlight housings. The vehicle was not repaired. The failure mileage was approximately 4,900.

The headlight lenses on both sides are growing a mold and fogging. The fogging is gradually worsening, and, at some point, will compromise the light emitted and result in glare. It is a well-known issue in these cars, and should be addressed under warranty, but mclaren refuses to replace the lenses for anyone who has tried to get this done by their dealers, myself included. It is clear that this is in violation of your regulations s5.1.2 (b) and (c): https://www.gpo.gov/fdsys/pkg/cfr-2004-title49-vol5/xml/cfr-2004-title49-vol5-sec571-108.xml it is estimated that, of the 3400 mp4-12c cars in the us alone, about 40% of them have the problem. I can not vouch for this number, but on a mclaren forum, this problem has been noted by many owners and their dealerships were unable to get mclaren to authorize replacement or repair. It is also noted that koenigsegg cars had a similar problem, and that nhtsa did take action. Photos are attached, but it is difficult to show how bad it really is with the photos. Approximately 30% of the lens surface is involved on the right, and 20% on the left side, and it is progressing. The headlight design failed to meet the standard that it would not have such issues when exposed to the environment. My car has had no accidents or any specific injury to the headlights.

The main headlights on the McLaren MP4-12C are susceptible to condensation, and mold that cannot be cleared as it is internal. This is caused by a faulty seal, or glue, holding the top clear glass, to the plastic molding which allows condensation to happen, causing the mold. Almost all McLaren MP4-12C's have the moldy headlights, reducing visibility and creating a hazard for the driver, as well as incoming traffic, as the light pattern is no longer uniform making it hard to see at night. The only solution is to replace the headlights with new ones costing more than $4,000.

The contact owns a 2014 McLaren MP4-12C. The contact stated that while driving at various speeds with the windshield wiper activated, the front windshield wiper failed to properly clean water or debris from the windshield as intended. No warning light was illuminated. The local dealer was contacted; however, the vehicle was not diagnosed or repaired because the VIN was not under recall. The manufacturer was made aware of the failure. The failure mileage was approximately 6,000.

The contact owns a 2012 McLaren MP4-12C. The contact stated that while driving during rainy weather, the front windshield wipers intermittently failed to operate as needed. An unknown windshield wiper error message was displayed on the instrument panel. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The contact related the failure to NHTSA Campaign Number: 13V541000 (Visibility); however, the VIN was not included. The manufacturer was made aware of the failure. The failure mileage was approximately 8,000.

This is the cars main navigation, radio, and other configuration critical to the cars operability and safety. McLaren calls this the IRIS system, and they issued an upgrade after the first one had many documented problems throughout the world, with the IRIS II system. They replaced them while the cars were under warranty, but once the warranty expires on your car, you have to pay upwards of $10,000 to replace what is essentially a radio touch screen. There is a high documented failure rate of the IRIS systems in following McLaren Models. The MP4-12C, the 650S, the 675LT. The part is made by Parrot in China, and they only sell the replacement screens to McLaren, creating a very expensive repair option. McLaren refuses to acknowledge a major problem. Problem: The IRIS screen which is a touch screen (resistive touch) fails to recognize your inputs. This happens typically on the right side of the screen, making it virtually impossible to use the Navigation when entering an address with the keyboard, or radio stations, or changing configuration settings. McLaren quickly replaced the IRIS I system with the IRIS II system and offered McLaren MP4-12C owners the option to upgrade from IRIS I to IRIS II. Those screens also have the same problem and stop working. A new replacement system out of warranty can cost up to $14,000. Because of the orientation of the screen, which is set in the center stack vertically, there is no aftermarket option to replace the faulty OEM unit. Your only option is to go to McLaren and pay $14,000. Due to the high failure rate in the IRIS I and IRIS II, I am asking you to please investigate the lack of response by McLaren to address the faulty units.
