Higher Mileage Roadsters

Higher Mileage Roadsters

I've been doing some research about high mileage Roadsters as I'd like to know how well they have held up. So far the highest mileage Roadster I've found mentioned online was at http://www.teslamotors.com/blog/northern-california-roadster-record with roughly 67,000 miles back in mid April. The article doesn't say much about how reliable the car has been, but I wouldn't take it into consideration anyway cause it is "Validation Prototype 11". Does anybody else have over 50,000 miles on their Roadster? If so, have you had any major problems? I've read that the battery pack loses %30 of it's capacity after about 50,000 miles. Has anybody personally verified this? Thank you in advance for your responses!

I will try to drive at that speed on my next trip and see how things go. I will be making about atleast 3 trips a month from Yuma to San Diego. Thanks for the advise.

Divesh, I have a 2008 Roadster with 19K miles. Based on my experience, you should be able to make a 185 mile trip on a full Range charge as long as the trip doesn't have a significant uphill (without a corresponding downhill) component, you don't make a lot of high acceleration starts, and you keep your freeway speed at 60 MPH or less.

Timo is correct that the slower your drive, the more miles you can get out of the battery. You can find the graph he is using on the Tesla Motors website under Enthusiasts, Blog, 2008 Blog Archives, Roadster Efficiency and Range Dec 22, 2008 Blog.

As you have probably discovered, when the battery reaches 10% capacity remaining in Range mode, the predicted miles remaining display disappears. At this point you have 24 Ideal Range miles remaining. You can see from the graph that you should be able to obtain Ideal Range performance at about 53 MPH.

Based on my experience and data Scott C has shared on this forum, the battery degrades approximately 2.4% to 3.0% per year. Happy motoring. Let us know how your future trips go.

Ideal Range after standard charge: 182 miles
(charging at 85F ambient)

To reiterate what the original poster was saying, can some of you Roadster owners comment on how well your vehicle has held up during ownership? Looks like we have good info on mileage, but I (and I think the OP) are also interested in what kind of maintenance requirements, headaches, that kind of thing you may have had to deal with.

Of course, what I'd love to hear is that you haven't had any issues ;) As a potential Model S owner, I'm concerned about adopting something so early in the production cycle without any guidance on overall vehicle robustness.

Thanks!

Other than bending rims on potholes, I doubt you'll hear much.
I think there was an issue with some of the headlights fogging up, but I haven't heard anything else.

Bear in mind that the Roadster served to prove and test the electrical core of Tesla's design concepts. You can assume that most potential weaknesses have been identified will no more impact on Model S. Whatever you hear is not necessarily of any relevance for Model S.

Most problems I heard of were caused by non-Tesla specific parts, such as e.g. tire pressure monitors, door locks etc. that can fail on any car. Electronics, battery and motor seem to be very reliable.

Model S will be produced in a different location, on new machinery and with new staff. To get overall quality to a high standard early on will be a major job. If the Roadster experience is any guide, you can expect good after sales service, no fundamental flaws and rather fewer problems than with most other newly designed cars. The intrinsic mechanical simplicity of an electric drive train does help.

So you want to know about reliability other than batteries....

I've had my Roadster almost three years and in the last two years the only service other than the annual check was when I drove over a 4-inch piece of aluminum that punched a hole in the sidewall of a tire. As far as can can tell I'd have gotten a flat tire in that situation regardless of what I was driving.

The first year there were a lot of glitches. All of them were minor. All of them were handled by the service department in a way that made me feel good about Tesla every step of the way. (I would have said they handled them flawlessly, but it did take three replacements of the navigation unit for them to figure out the problem was caused by a mispositioned antenna. If they were flawless they would have figured this out the first time.)

No no, that's exactly the stuff I want to know. If I'm choosing to buy a 1st generation car, I'll have to expect some of those little things as they get up to speed with their process.

My nightmare would be Tesla telling me it's gonna cost me $300 to import one of their road-crews to come to my house and fix a car that doesn't start, or a sunroof that leaks, that sort of thing. I would expect that the premium I pay for the vehicle will also gain advocacy for me by Tesla's maintenance and/or customer service personnel.

Sounds like they're customer-focused which is great to hear. I love their vision and I want to do my part in supporting it...of course, I also want to drive that cool car that they've built ;) I'm so excited for the thing, I feel like a salesperson at work telling all my buddies about it.
