I may have to imrovise here and go back to my initial idea of using a lithium button cell in series with a diode to prevent it being charged. Anyone see any issues with that approach? |

I think clearly the older one gets, the harder it is keeping up to date with new innovations if you're not fully immersed in the field as a career (I'm not!) |

If so, I suggest toyota corolla or prius hybrid. I recently went through a new vehicle search and reliability, safety, fuel efficiency , usable space and creature comforts were my primary criteria (roughly in that order). I consulted lots of different reviews and tried to get repair types and numbers. I ended up getting a toyota highlander hybrid limited. (@ 36 MPG). The subaru ascent and audi q5 (and 7) were fairly serious contenders. I did look at hundi and kia (sorento). They both got high marks as well but no hybrid models. Same for the subaru ascent. In the end, hybrid/fuel efficiency sorta drove my thinking. I did look at e-vehicles but from my perspective, they arn't 'quite there yet'... I did drive a 2021 Prius as a test (as long a I was looking). That is why I endorse it. Now if you are a DIY repair person, a hybrid may be out of your comfort zone. I have been downloading the toyota FSMs for my vehicle for the last 24 hrs...trying to understand the basics of the propulsion system and even found a crude simulink model of the electronic drive - ICE tandem to play with. Lots of computer power in a hybrid, and being a CE & EE, I am hoping they employed good sw rel and defect detection practices in their design (Since I teach this stuff I am always a bit curious how companies do it). If an EMP hits, I'll be going nowhere but I'll take my chances..... good luck J |

Each model suffered from a unique set of component reliability issues...took me a while to finally ditch them. I live in the rust belt and was appalled to see my last vehicle significantly eaten away by rust in combination with nagging brake issues and the infamous death wobble (DW) due to their 'unique' front steering design. An interesting story - a few years after Daimler bought Chrysler I was at the dealer parts desk getting some factory only fasteners and crankshaft position sensor. The parts fellow had a hell of a time finding the right fasteners in the system. He related the story to me that one of the first things Daimler did was look across all the Chrysler vehicles and inventoried the fastener types. Something on the order of 150K+ different ones. To save a bunch of money, Daimler standardized the fasteners across all the products down to something like 30K (numbers aren't accurate but the percentage reduction is, afaicr). |
