My wife’s 2012 Grand Caravan has a quirk: an intermittent no start condition when the key is inserted into the ignition and turned. Dash lights come on, but engine doesn’t crank. Doesn’t seem to matter if I cover the brake or not. Doesn’t seem to matter if the row the gear selector a couple times. After 3 or 4 attempts of turning the key it suddenly starts and drives.
I researched fuse boxes, but the symptoms don’t quite match. I researched the neutral switch device, but once again symptoms don’t quite match. Ignition switch might be the culprit? My red herrings:
- The car has stalled, intermittently, a half-dozen times while driving to work at roughly 35 mph. Pull over, and it restarts.
- My best friend’s wife has a 2013 Town & Country with the same problem. We were both shocked.
- When we first bought the car, we lost the one and only original key. So not wanting to pay the dealership fee of $500+, the internet found a guy who could do it from the back of his car for $200. The keys are Dodge keys, but not Grand Caravan specific. They have worked fine, but I wonder if once in a blue moon the ignition switch decides it doesn’t like the impostor keys? And my friend, who has the same problem, has their original keys?
The van has been a godsend for our three kids and dogs, so the idea of going to a SUV or Mega-truck sounds like a lot of money for less space, but I can’t have her driving around wondering if she will stall in traffic, or — more annoying — just can’t start after loading up to go somewhere with the kids. The dealership is useless unless they can replicate it. And it never does it when you want to show someone.
Perhaps the car is possessed by the ghost of passenger from its prior rental life?
That’s right people: I need more user-submitted queries to keep this series alive!
The same rules apply, just about anything besides the “Help Me with my
First World Problem Car Purchasing Dilemma” is on the table. If you’ve seen it on an automotive message board, let’s tackle the issue here. I need your content!
No more begging, let’s get back to Craig the Audiophile looking to cancel his noise-cancelling Grand Cherokee:
Tuners and researchers have searched for ways to pull data from cars and modify it ever since the introduction of the first on-board computer in the late 1960s. The advent of fuel injection and computer-controlled engines in the 1990s brought computerized tuning front and center. And while the OBD2 standard — made mandatory in 1996 —standardized the interface and made it easier to read diagnostics and log some parameters, modification and advanced logging was still complicated and expensive.
Professional tools and open source hardware popped up in the past decade to allow deeper access into a car’s electronics, but most ready-made products were still expensive. Open source variants also required knowledge of soldering and programming. Now, Macchina has taken the best of both worlds and packaged it into an inexpensive product that should prove useful for researchers as well as tuners.

- Theflyersfan Some of my extended family have lived in Orange County/Anaheim area since WW2 ended. They were in Anaheim before Disney and when there were actually orange groves. When I lived out there, I battled up from Ventura County down there a few times a month for dinner and ballgames and it was always interesting to hear from the older members about what things were like out there before it all really blew up. And how starting in the 1950s, they could no longer see the mountains anywhere and the sky was frequently this sick brownish haze. And then starting in the late 1990s, when things really started to clean up, they said there were now more days when they could see the mountains again compared to not, and it was really only the Santa Ana winds that brought in the gunk from the Inland Empire into the basin. There's still a long way to go - during the pandemic, it was wild seeing videos of how clean the air got when so many people were working from home, but it shows that even with all of the heavy industry there, it can be done. I know everyone is all over the map when it comes to climate change and causes or if it's happening, but regardless of views on that, I think we can all agree that burning less gasoline and diesel helps everyone breathe a bit easier when we don't have as many smog alert days.
- Fred It's always someone else's fault. Now where is my bonus?
- Canam23 I moved to Los Angeles in 1968 and half the time the air was unbreathable. It is 100% better now thanks to the work of the AQMD. If you remember, when the first pollution controls were mandated in the 70's, Detroit said it was impossible to meet them. The Japanese just started working on the problem and just did it. All the tougher laws to mandate air pollution have resulted in not just cleaner air for our children, but also much more efficient engines in our vehicles. So Stellantis, I'm not buying it.
- Theflyersfan Nope. Has nothing to do with Gladiator sales falling off of a cliff and having 5-figure discounts.

And people want the 4xe models, so that could reverse the trend if they crank more of them out. But let's blame the government for everything. It'll lead a news cycle on any red hat network.
