I’m getting frustrated with dealership service.

My 2019 F350 Lariat Ultimate Diesel occasionally will not start first time in the day and displays Blind Spot Fault, Cross Track System Fault and Pre-Collision Assist not Available. I provided the dealership with videos where I captured the issue twice in the last 2 months.

First time it was at the dealership for 8 days and they gave it back to me saying they couldn’t duplicate it so they didn’t attempt a fix. Two weeks later it failed to start for me again. I called Ford Customer Service, they opened a case and told me to bring it back to the dealership which I did 3 days ago. Today I called the dealership and once again they said they couldn’t duplicate it. I asked if they opened a case with 2nd level tech support and they said they couldn’t open a case until it malfunctioned for them while it was on a diagnostic computer. My videos aren’t good enough for them.

The last time I had the issue I monitored for DTCs with an OBDII dongle and Forscan. There were no DTCs logged or showing. I printed out a 4 page list of module status while the faults were displayed on the dash and gave them to the dealership.

So far the dealership had the truck for 13 days, 8 days first time and it will be 5 days by Monday. Florida lemon law may need to be used. Florida Lemon Law kicks in after 15 cumulative days at the dealership or 3 times for the same issue.

The reason I’m frustrated is because of my background. I spent 38 years in Field technical service. I was a tech rep, local tech specialist, SE region Tech specialist and retired as a Manager of Technical Services for a high tech company. To me it’s crazy that the dealer hasn’t opened a case or escalated it.

I have to wait now until Monday to call the Ford Customer Service rep who is handling my case to see what direction he wants me to go.


UPDATE. I just looked at Florida lemon law https://www.bbb.org/us/Storage/16/Do...-LLsummary.pdf

it states Lemon law does not cover trucks over 10,000 GVW. So perhaps a F350 1 ton is excluded. That would suck. ��

 

This may sound simplistic, but check all battery cables and grounds for tightness and good clean connections. If your truck is brand new, maybe something simply wasn’t connected properly from the get go.

also make sure your batteries are actually good; doesn’t matter if the truck is new.

Hopefully it will end up being something simple.

good luck

 

I had a similar experience with my truck, it would crank but not start........numerous times, dealer had it forever and could not duplicate, until I got it back and a few days later towed back in. No CEL, no DTC's. But finally when I had it back it happened again, but this time I had a code reader with me and pulled three codes. (It would only gives codes while cranking...odd). Turned out to be the fuel pump control module, intermittent failure. Two months after the repair and the truck seems fine. I bought a spare from Ford ($35) and keep in under the back seat, 10 minute install. I don't know if this is your fix, but for $35, it might be worth a try. The module is located on the rear cross member, passenger side, just in front of the rear axle.

UPDATE:

Talked to my rep at Ford Customer Service. The dealership had not escalated the issue as of today. The rep was going to contact the dealership and put them in touch with his sources to work out a plan to fix it and call me back in 3 days, Thursday. Holding my breath. .

 

Do you keep any kind of OBD II adaptor plugged in all the time? I remember reading certain adaptors were causing intermittent communications errors that can cause what you are describing. Also I would check the connectors at the left rear frame rail area for water intrusion, your truck is a 2019 so it has the updated parts but I would check them anyway.

 

Thanks for the suggestion.

initially I did have a OBDII Bluetooth dongle connected and thought that was the cause. After I removed it I stil got the faults occasionally so I ruled that out.

I haven’t checked any connectors yet. I wanted to let the dealership do their thing first to document the issue. Unfortunately as of this morning they have not been able to duplicate it after having it a total of 16 days.

 

I hate to say this but, in my experience, if you aren’t physically there, your truck is not at the top of the priority list. When I was having exhaust valve issues during regen, I left it at the dealership 3X and they literally did not drive it one mile. And I told them that it only happened under load, during a regen. The 4th time, I asked to ride with a diesel tech until the problem was replicated - we did, it took 7 hours and 300 miles, and a vacation day but we logged the problem, they fixed it. They are so strapped for good workers and available hours its ridiculous.

 

Yep, I would check all of the connectors back by the spare tire. This sounds like the sort of weird things that were happening to trucks that had water intrusion and corrosion in those connectors.

 

Note that it is 10K GVW not 10K GVWR. This is a very important distinction.

Weigh the truck. If it weighs less than 10K with everything that is permanently attached when in use (like permanently mounted aux fuel tanks or tool boxes) then the lemon law applies.

 

Thanks for that correction.

UPDATE AGAIN

Ford customer service called me and said the same thing the dealer said. Until the dealership could duplicate the issue there is nothing to do.

So tomorrow I pick up the truck. When it does it again I was told to bring it back to the dealership.

I contacted a Lemon Law attorney. They said I have a good case and should have either a full refund or offer for a replacement if I file Lemon law.

I’ll pick it up tomorrow and check out the rear connector for corrosion or wetness. If it looks wet or corroded I’ll be really pissed. If it looks good I’ll wait until it does it again and call the dealership while the faults are displayed and ask them to come by to see it themselves. If they refuse to come to see it I’ll bring it back a 3rd time and let the attorney loose on them.

I also may just wait until the 2020s come out and buy one of them. If I had a PCO I’d be trading it NOW.

NEW For 2020

Does anyone have a good picture that they can share of the location of the connector by the spare tire that causes the problems?

Don’t forget to stop buy an autozone or O’Reilly to have them test your batteries. If it’s doing it in the morning, first start up of the day, and it’s cold, then it could be the batteries dipping below whatever threshold ford set for certain parts to power up.

 

UPDATE:

Picked up the truck this afternoon after dealer could not duplicate it for the 10 days they had it.

I asked about the connectors. Service writer knew about the potential wet connectors on passenger side and said they were all checked and were not wet of corroded.
They also tested the batteries.

So I'm back to square one.

Before dropping it off last time I undid the forscan programming and loaded the original values that I had saved. I had added digital TEMPS above analog gauges, changed signal light flash count from 3 to 5, added % DPF page. I will leave the stock values for a while and see if the faults reappear.

 

UPDATE:

This morning it started fine but I brought up forscan and these DTCs are logged. The mileage from when it was logged was the mileage with I picked it up from the dealership.

I wonder if this is a telltale sign of a low voltage issue that causes the no-start. WHAT DO YOU THINK?
