Check Engine Light On problems of the 2008 Toyota Highlander

2008 Highlander hybrid limited check engine light came on and showed code p0a1b - drive motor 'a' control module, the code was cleared manually and the check engine light went off, the next day the light came back on after driving about 3 miles then parked. The next day the light went off on its own as we took it to the Toyota dealership and has not been back on since driving it there and back, the dealership said they drove around a little and the light never came on, we brought it home and have driven about 7 miles without the light coming on. According to the local Toyota dealership and corporate Toyota there are no recalls for our VIN but it is showing all signs of the inverter assembly recall that affected 235,000 vehicles in the recall. Toyota quoted the repair at $9000+ and even though it has the symptoms of the recalled vehicles they will not fix it because it is not on the recall list and there is nothing they can do. The repair cost is more than the value of the car.

The contact owns a 2008 Toyota Highlander. While attempting to accelerate, the vehicle hesitated and the check engine light illuminated on the instrument panel. The vehicle was taken to the dealer. The technician diagnosed that the fuel pump needed to be replaced. The technician stated that the fuel pump failing was a known issue. The vehicle was then put through a stress test and the service department kept and drove the vehicle. The service manager stated that the failure was not the fuel pump and that there was an issue within the system once the vehicle warmed up that caused the vehicle to lose power. The vehicle was not repaired. The failure mileage was 90,000.

I purchased a qualified pre-owned 2008 Toyota Highlander sport from rice Toyota in greensboro, nc in February of 2013. Since that time, I have properly serviced the vehicle and retained all service records. On or about March 31, 2015, while I was driving home from work on I-40 (65 mph interstate highway), the engine in my Highlander suddenly stalled and the check engine light came on. I coasted into a rest area (luckily) and was towed to a service station in greensboro. A complete diagnostic was performed and it was determined that the engine failure was due to a faulty engine valve spring. Every mechanic I have spoken with have indicated that a valve spring should not break on a 2008 Toyota with around 100k miles. I searched online and found that Toyota has recalled hundreds of thousands of certain Lexus models, including models from 2008 with the same 3. 5 liter v6 engine as is in my Highlander, for faulty valve springs that result in sudden engine stalling. Rice Toyota has refused to provide any assistance, as has Toyota corporation. Further, Toyota corporation has refused to provide me with any information regarding the manufacturer of the valve spring in my vehicle and/or any indication if the same valve spring was in the recalled Lexus modes. I have seen class action law suits filed against Toyota for concealing issues with valve springs. This defect can be very dangerous as the vehicle stalls suddenly and without warning. I need assistance to motivate Toyota corporation and rice Toyota to correct a clear design and/or manufacturing defect that caused a potentially dangerous engine stall in the middle of a major interstate highway.
