Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Check engine light came on after driving the car about 472 miles. Called dealer repair, which instated that it was just the gas cap loose, which he had us remove and retighten. We were advised to keep driving it and that the check engine light would eventually go out. We drove it for a few more days and then had two different local mechanics shops check the code on the check engine light. Both said that the engine was misfiring, either random misfire, or misfire on cylinders 3 and 4. …”

“On 5/24/11, while driving through an intersection, my Forester was hit broadside by another vehicle that ran a red light. The impact of the speeding vehicle caused the Forester to spin 360 degrees and flip-over on the driver's side. I was left trapped inside the Forester and witnesses pointed out that the engine and transmission continued to run after the Forester flipped over. Apparently there is no engine or transmission kill switch. Furthermore, there is no interior release of the rear hatch. …”

“I am being told by the manufacturer that the engine failed due to lack of oil changes. I changed the oil on 7/6/11 at 10,639 miles. The engine then failed at 22241 on 2/1/12. The engine holds 5.5 quarts of oil but per the manufacturer had none in it at the engine failure. How does a new vehicle burn 5.5 quarts of oil in 11602 miles? There was also no warning light of any kind to tell me that the engine oil was low. The manufacturer stated that the oil level had to be lower than 2 p.s.I for the light to go off and warn me and at that point the engine would already be damaged. …”

“When the check engine light (cel) is activated by an emission control failure Subaru has programmed a shut down of the anti-lock brake system (as well as shut down of cruise control). This ABS shut down could occur for a simple loose gas cap which is common cause of cel failure. The section 3-16 on cel warning light/malfunction indicator does not inform the owner that a cel event will be accompanied by the disabling of the ABS. The driver finds this out only because the cel is accompanied by blinking cruise light and steadily illuminated ABS light. …”

“The contact owns a 2011 Subaru Forester. The contact stated that she noticed an abnormal odor coming from the exhaust. The contact stated that there was no warning light illuminated. The contact took the vehicle to the local dealer, where it was diagnosed, and the contact was informed that the seals needed to be replaced. Additionally, the spark plug gaskets and gasket rocker needed to be replaced. The contact stated that the dealer removed the engine and replaced both cam carrier covers. …”
