So i just picked up my brand new Ascent Touring last night from dealer and this morning on my way to work, the check engine light and RVP (eye sight) light came on. And the car become rough to drive. I took it to nearest Subaru Service and it had been one whole day and they had no idea what is wrong with it. Have anyone experienced similar thing??? The dealer contacted me saying that they don’t know how long it will take because they don’t know what was wrong or how to fix it.. i planned to take this car for a road trip this weekend and i feel so disappointing with my very first Subaru.
This is why I never go far from home without an OBD II scan tool. A basic one is not expensive, but in an age of 'idiot lights', the root cause of your problems can get buried or lost in the diagnostic process. I had an RV on a Dodge Sprinter 3500 (Mercedes Benz) chassis. At 22,000 miles the transmission failed more than 3,000 miles from home. Chasing warranty dollars, the dealer in central Florida attempted to overhaul the transmission. Ten days later, the rebuild only lasted 35 miles and had to be towed back in. Second overhaul, lasted longer (300 miles) and never made it out of the state. Limping into another dealer, a new transmission and torque converter was installed. Lost in all this was any information of what caused the initial and second failure. I was told that because of the circumstance, a remanufactured transmission should have been used and the defective one sent in for analysis. If I had a scan tool, I could have recorded all the trouble codes for myself. A few years later, the trouble light came on a short time after loss of power. This time I had a scan tool that returned a code that indicated a turbo boost pressure loss. I discovered a defective hose connecting the turbocharger to the intercooler. I elected to take it to a local competent Dodge dealer to replace the hose and test the turbo system. I have a new RV, but this time the Sprinter chassis is sold by Mercedes Benz. Even so, I won't leave home without a scan tool. Modern vehicles have several computer control systems interconnected by a data bus. I would not draw any conclusions yet with a failure of one of the early Ascent cars built. It could be a one-off thing. Then again, sometimes things can get out of hand real fast. One only has to look at the Boeing 787 Dreamliner to see a less than perfect rollout. Exploding batteries and now Rolls Royce engine problems. It is early yet, I would not worry too much. I have a OBD scan tool that works dynamically and connects to a mobile device like a phone or tablet. It is possible to monitor what is going on in real time. Recently, we were able to identify which of the four O2 sensors went bad on a friend's 1998 Lexus LS400. Saved him a trip to the mechanic. If you do use a Scan Tool to retrieve trouble codes, I would caution you not to reset the check engine light and erase codes. This could interfere with the technician's ability to diagnose problems. The computer records how long the vehicle was operated since the MIL (malfunction indicator light) came on.
