Intrax has been making shocks for 50 years. Conrad Buck with Mars Orbiter in Germany, a well respected Roadster service organization, originally helped them develop a shock package for the Roadster. Our suspension master mechanic with 12 years experience with exotic car suspension is further...

Intrax is on vacation all of August. We have installed a number of these Roadster specific shocks and are very pleased with the results. We have ample inventory: https://grubermotors.com/product/tesla-roadster-shocks/

We are used to seeing single cell failures which result in declining range after each charge, sometimes so severe, the decline results in a few miles range lost after every charge which of course is the BSM kicking in and limiting charging due to a growing brick voltage delta. These cars do not...

We have begun to document a new decline in the first 3.0 ESS Main Battery Packs. Roadsters begin losing punch and power, and eventually decline to undriveable. We are finding cells with increasingly higher impedance, with brick voltage drops during 100% throttle calls. This video documents our...

The major difference between us and other shops is we do not need to replace modules in the HV battery pack. We actually repair them by isolating the parasitic cell, and neutralizing it, which costs less than a module swap. This has become the preferred way of repairing Roadster packs since...

In this video, we provide a detailed, step by step method, of removing the Power Electronics Module (PEM) from a 2.x Tesla Roadster, to prepare it for shipping to a PEM rebuild facility, and preparing the Roadster during the downtime.

Tesla Roadsters are climbing in value. Are they becoming collectible? What does this mean for other Tesla models? In this video, we explore the fundamental requirements of what makes a car collectible, and how and why the Tesla Roadster, although relatively new to the scene, is on an...

This particular Roadster had one of 6,831 cells starting to die and typical symptoms are a gradual range decline as the offending cell drags down the rest of the cells in a brick. As with all Roadster battery issues, time is of the essence and if caught early, the Roadster battery pack can be...

Our GMC website is under re-construction and the Newsletters will be back up soon. The one dealing with this issue is:

A Cybertruck is not the only Tesla vehicle that can beat Ford in a pull. https://www.youtube.com/watch?v=oeWKp3ro2zY&t=17s

The 3.0 packs do not respond as well to recovery efforts compared to legacy Roadster packs. With a 6 month brick, we usually find 1 or 2 sheets that need to be replaced. The 3.0 pack has 10 out of 11 bricked sheets. Oddly, some bricks within a sheet are healthy, and one right next to it may...

Gruber Motor Company (GMC) is fortunate to have extensive background in servicing complex electronics, often without the support of OEMs which ends up making us even more skilled since without schematics and documentation support, we have to reverse engineer and develop our own. The seemingly...

This morning, a 2010 Roadster will be crossing the auction block in PA. The car actually belongs to Tesla (trade-in?), most belong to insurance companies who have settled with the original owners. It came in November of last year showing 71 miles range, alive and runs and drives status. It...

We are repairing and rebuilding a 1.5 PEM in a 2008 Roadster. The sticker highlighted, is a nostalgic testament to the influence AC Propulsion had on early Roadster design and development. Arguably, without this small company's influence, and the Tzero proof of concept vehicle, Tesla Motors...

Considering the AC Propulsion Tzero was the design template for the Roadster, and the beta Roadsters used this inverter technology, at some point the Roadsters might have included V2G since the Tzero was V2G capable. Fortunately, the Tzero documentation, including schematics and operations...

We intend to put this car back on the road so all the pieces, some of which will have to be replaced out of our stock, are needed. Feel free to contact us. We do have some CF pieces in our inventory.

We bid the car up to $25K even and won. The Copart "Runs & Drives" category is often misleading, but encouraging. We bought a Model S from Copart earlier this month with the same claim, only to have them tell us at pickup time, there are no keys. When we asked how it runs and drives, they...

The error ID:264 BSM: PEM cable fault is due to an issue with the HVIL, High-Voltage Interlock Loop, that runs through the PEM. The switch mentioned by PV-EV on the TMC forums is always the first thing to check. That switch makes, or breaks, the HVIL, so make sure the lid to the PEM is screwed...

Due to ongoing routine investigations into what was one of the largest fires in Arizona in some time, I am not at liberty to divulge some details, but we do own the EV community an explanation: 1 - Gruber Motor Company proudly displayed Tzero #2, kept it maintained and functioning, and shared...

There are only three of the Tzero's in existence, and I am not sure if the previous owner is on TMC. It is a remarkable car, a piece of automotive history especially in this millennium. Preferring to honor the TMC forum guidelines, I am unable to discuss pricing.

The higher grade dielectric insulating material and IGBT Transistors we use, can be sourced. The PEM disassembly and retrofit installation however poses some challenges and risks. For example, the current sensing boards, which have to be removed, are bolted directly into copper buss bars...

The most common problem we are seeing with Tesla Roadster Power Electronics Modules (PEM) noted in a Tech Tip we generated and reported a year ago to forums and Tesla Service Centers, is becoming rapidly more widespread. We even spoke with the original manufacturer of the PEMs, and advised them...

This totaled car was on the auction block in Phoenix yesterday, and unlike most cars sold for salvage, this one has an interesting story reading almost like a novel with triumph and tragedy. We often buy Tesla cars for parts, and noticed the long model number. The insurance lots processing...

If this guy sells this Roadster at the asking price, it just raised the bar.

Tesla Motors refers to the Roadster's battery pack as the Energy Storage System or ESS. The ESS contains 6,831 18650 Lithium Ion Cells arranged into 11) "ESS Sheets" all connected in series. Each sheet contains 9) "bricks" connected in series. Each "brick" contains 69 cells connected in...

We are aware of the next generation IGBT's Austrianer and you are right - a better product is now available. We will be extensively testing these newer, more efficient IGBT's in one of our test mules and report findings on TMC. Less heat dissipation is of course a plus.

The only 1.5 we have had in the shop Wiztecy, owned by one of our Managers at the time, preceded our realization this material is deteriorating. Unless Tesla switched insulating material during the production years, it is likely all PEMs will need this upgrade.

Yes it is Botbldr45. Once we noticed a clear pattern of deterioration, we now disassemble all PEM inverter sections and replace this material as a standard operating procedure. We sent this Tech Tip to 64 Tesla Service Centers to share this information, and hope they also replace this failing...

In every Tesla Roadster PEM we have serviced to date there is evidence of failing thermal insulating material between the IGBT Inverter Transistors and Aluminum Heat Sink. Corrective action is PEM removal and disassembly, and replacement of the thermal insulating material with an upgrade...

Warren Buffet invested in this company, so it must be good.

The T Zero pictures available online are few and low resolution. That just changed. I posted the first of many more on Flickr at - Pete Gruber’s albums | Flickr __________________________________________________________________________ Every collecting pursuit, from comic books to Beanie...

We have been buying salvage Roadsters. Would you be interested in a list of decommissioned cars?

So this happened yesterday. I get home, ready to unload groceries I had just placed in the trunk, and I hear Click, Thunk, and only one side opens slightly. I then fiddled with the dash switch, key fob, and placing the key in the rear lock, and all I hear is Click, Thunk, and only one side...

Of the 4 Roadsters we have, each one came with a different master key for the locking lug nut. Take a picture and check Ebay for Lotus master keys and match your pattern.
