| Description of the problem | My 2012 hyundai sonata turbo has the following persistent issue. When the vehicle sits over night, in cool weather conditions of about 60 degrees and/or lower, upon first start in the morning it will not rev past 4000 rpm (while driving) and as a result it doesn't have the power to merge onto the highway in a manner that i would consider safely. I know of a technical service bulletin that hyundai has released that's suppose to resolve this issue however, i also have knowledge of about 10 vehicles with this same issue, some the issue persisted even after the dealer claimed to have repaired it. What i consider the main safety issue to be is; there is no indication/alert within the vehicle's dashboard illustrating the issue affecting the acceleration/performance. My vehicle has normal power city streets or at about 30 mph or less. I discovered the issue when trying to merge onto a highway, due to lack of acceleration power (which my vehicle should/did have), i was nearly rear-ended by a 18 wheeler as i was trying to get up to highway speed. This is a huge safety issue. No check engine light has ever turned on. My vehicle has never been in an accident and has about 13,000 miles on it now. I would greatly appreciate your attention on this hazardous matter. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6). |
