Any of you guys experiencing some of the problems listed below as some EcoBoost owners have?
“I am unhappy with my new Ecoboost Lariat.. it has 2900 miles on it. I’ve had some weird issues and have been back to the dealer but they tell me everything is okay. I’m wondering if anyone else has had similar concerns or if this is just the normal behavior of the truck. I had a 2007 Lariat with the 5.4 that was smooth as glass and never had any issues.
1. Rough 1-2 shifts.
This has been a real problem spot. The shifts are rough when cold and sometimes when warm. 1-2 often gives you a kick… but the problem is intermittent. Things were bad enough on I-95 in stop and go traffic a few weeks ago that I just locked the truck into first gear with manual. The shifts tend to be rougher under light throttle inputs but that’s not always the case.
2. Weird surge feeling when stopping.
When coming to a complete stop, the truck seems to have trouble getting the motor out. I feel like I’m braking through the engine. At about 1000 rpm, the tach bounces a little bit by a few hundred RPM once or twice. Only when you’re finally at a complete stop does the engine return to idle.
3. Fast idle when cold.
Upon start up.. and for the first few miles.. the idle is exceedingly fast. It’s annoying when pulling out of a lot and stopping. You really have to brake hard to hold it back.
4. Holding throttle in when off the pedal.
Say you’re in a parking lot hunting for a space. You completely take your foot off the gas.. but the truck hangs onto the throttle at say 900 or 1000 and takes you on a trip without your foot being anywhere near the pedal.
5. Tach bounce at idle.
There’s a fluctuation in the tach at idle.
Let me say that I am thrilled with the engine at speed.. it has enough power to launch you and everything else into next week. I seriously dislike the truck at low speeds and feel it needed more time on the proving grounds. If anybody else has had similar/issues concerns I’d love to know about them and what the dealer did or didn’t do.
Thanks.”
