Lost power on highway my RX350 (2007) lost power going 65 mph on a highway, and began to slow down quickly. With a truck on one side and another barreling down my behind, I tried to accelerate but the vehicle began to shudder and shake violently! by some miracle, I managed to swerve to the shoulder across 2 lanes, and avoided getting hit by inches! got the vehicle to the Lexus dealer and they found out that it was a premature ignition coil failure - the vehicle has only about 42000 mi on it. Asked Lexus corporate to: 1) do a full investigation so as to prevent similar life threatening safety failures, and 2) reimburse the cost of repair at a minimum Lexus customer service responded with a verbal offer to bear 10% of the cost of repair - and no promise of any investigation! talk about adding insult to injury. We'd undergone a traumatic event, almost losing our lives - my wife had started screaming on the side of the highway and would not get back into the vehicle! I refused, of course, and paid the entire (and substantial) bill myself. I'd like all readers to be aware of the power failure and be especially careful out on the highway. Also be aware that the Lexus promise of perfection seems to be mainly lip service nowadays - safety apparently is not in their definition of 'perfection'. to see such a serious incident being treated so trivially was totally at odds with the Lexus mission and the Lexus promise to its drivers.

I have now had to replace 3 ignition coils. I only have the paperwork for 2 times, but each time the car began to run rough and the engine went off at stops, and the electrical system light went on. The first time this happened, which I think was in 2010, the Lexus technician said it was a fluke. The second time (above date), the Lexus technician said he was beginning to see a lot of ignition coil failures. This last time (today), the technician said replacing faulty ignition coils is now common, and just a part of maintenance. He also said some people were choosing to replace all 6 of them at once so that they wouldn't be stranded at night or on the road, and to save money. Obviously, there's a major problem with Lexus RX350 ignition coils.
