What is luxury? In the American car market, that question doesn’t have an easy answer. Driver-focused performers like BMW’s 3-series sell well here, but so do feature-loaded versions of mass market sedans, like the Lexus ES. Blinged-out baroque still has its adherents, but as the Napa Valley hotel where the Cadillac CTS Coupe was launched proves, a more subtle, sophisticated version of luxury is gaining popularity as well, differentiated by the use of recycled materials and environmentally-friendly technologies. So where in this fragmented and changing category does the CTS Coupe belong?

Chrysler is sending out recall notices to owners of 25,000 Dodge Calibers and Jeeps. The reason: Accelerator pedals could become stuck and cause unintended acceleration, Chrysler said according to a report in Reuters. Sound familiar? Wait, there is more … (Read More…)

First developed by Holden in 2004, GM’s Zeta platform now underpins vehicles as diverse as the Statesman/Lumina/G8/Caprice sedans, and the Chevy Camaro. Originally designed for full-sized , rear-drive Australian sedans, Zeta was downsized as far as it could be for the Camaro, which reviewers largely view as overweight and rather too ungainly for true sportscar status. Accordingly, GM has been developing a new rear-drive platform known as “Alpha,” which will form the basis of GM’s performance and luxury RWD models for the considerable future. Last we heard about Alpha was last August, when Bob Lutz swore there was no development underway of the platform he compared to BMW’s 1-/3-series. According to Motor Trend, work on the Alpha platform has begun… but there are already signs of trouble.

I’m too young to remember the 1970s, but I have recollections of a Cadillac-based abomination known as the “Castilian Fleetwood Estate Wagon.” Perhaps the recent success of Cadillac-based trucks made someone at the RenCen give the Cadillac Wagon a second look. Yet the CTS Sport Wagon isn’t a cobbled-up engineering afterthought, though it reeks of branding desperation: the American icon formerly known as the pinnacle of everything now goes for entry-level luxury success in a station wagon. And that’s why this mirage hailing from the days of Motorized Malaise has some ‘splaining to do.

Here’s TTAC’s and the web’s only complete guide to Toyota’s gas pedals (so far), with tear downs, pictures, analysis, explanation, the shim fix, and commentary, all consolidated into one portal:

Part 1: Exclusive: TTAC Takes Apart Both Toyota Gas Pedals: Tear down of both the recalled CTS pedal assembly and the non-recalled Denso pedal assembly. Note: Assumptions and conclusions in this initial tear down lack the more complete understanding of the importance of the friction arm aspect of the CTS unit.

Part 2: Toyota Gas Pedal Fix Explained – With Exclusive Photos: Describes Toyota’s proposed fix for the recalled CTS gas pedal assembly, with detailed photos and graphics. Explains the significance of the friction arm assembly and its limitations.

Part 3: Toyota Gas Pedal Fix Simulated – Friction Reduced, By Too Much?: TTAC simulates the fix prescribed by Toyota for the recalled CTS pedal assembly, and notes how the fix changes the degree of friction, and the possible unintended result. With detailed pictures

Part 4: Why Toyota Must Replace Flawed CTS Gas Pedal With Superior Denso Pedal: Detailed analysis with pictures of the two pedal assemblies, an explanation as to why the Denso design is superior, and a call for having all CTS pedals replaced with the Denso pedal.

Part 5: TTAC Does The Toyota Pedal Shim Fix:  Stop Gap Solution At Best: Toyota’s solution is carried out here with detailed pictures, the whole Toyota document detailing the fix, and our commentary.

Part 6: Toyota Floor Mat/Gas pedal Recall Includes Computer Reflash And Trimming Of Gas Pedals: Info on the details of the floor mat/gas pedal interference recall.

Part 7: Toyota Recall  Creates Unintended Accelerator Consequences: As predicted in Part 4 (above), the CTS shim fix reduces the carefully designed amount of friction required for comfortable and smooth pedal action to the point where pedal action may now be jerky and potentially unsafe.

Reuters reports that the Detroit offices of Denso, a major Japanese automotive supplier, has been raided by the FBI as part of an on-going investigation into alleged anti-trust violations. Denso spokeswoman Bridgette Gollinger said the investigation was “absolutely not” related to ongoing recalls by Toyota. Denso supplies accelerator pedals (see above) and other components to the automaker. “We are cooperating with the investigation,” Gollinger said. The FBI raid was first reported by The Wall Street Journal, which said that federal investigators had also searched the Detroit area offices of two other Toyota suppliers, Yazaki and Tokai Rika. Curious coincidence of timing as this happens while Akio Toyoda testifies on Capitol Hill.

Update: a portal to all of TTAC’s articles on the subject of Toyota gas pedals is here:

Toyota has sent instructions and the shims for the field fix of the recalled sticky CTS gas pedals to dealers as of today. We have obtained the instructions (pdf here) [Hat Tip: Roxer], shims, and carried out the fix on a new CTS pedal accordingly. Follow along as we carry out the fix, and how we arrived at our unhappy conclusion. (Read More…)

One of the lingering concerns over the Toyota recall is whether Toyota’s “precision steel” shim fix to the recalled CTS gas pedal assembly will be a reliable long-term solution. Our analysis indicates that these questions might be well-founded, and we’re not the only ones concerned about the viability of Toyota’s proposed fix. In an interview with Toyota’s Jim Lentz yesterday evening, NPR asked why Toyota was using a redesigned pedal for new production, but only offering the shim fix to existing customers. Lentz insisted that the repaired pedals would be as good as the redesigned pedal, that the costs of repair and replacement were about the same, and that the main reason Toyota was repairing rather than replacing recalled pedals was the desire to “get customers back on the road… as quickly as we possibly can.” That’s when NPR went for the jugular.

According to a PR Newswire release, a class action suit has been filed against Toyota and supplier CTS, alleging “inherent design defects,” specifically a “lack of failsafes” in Toyota’s ETCS-i (Electronic Throttle Control System-intelligent), in use since 2001. As in not the pedal assembly. A similar suit was filed in the US last November. Today, Toyota’s Jim Lentz was emphatic that electronics were not the issue with the ongoing recall, but shortly after the US suit was filed, Toyota quietly announced that an electronic brake override system would be installed on certain vehicles with automatic transmissions. Is that as good as an admission of guilt? You can bet the lawyers are already saying so. The full release is available after the jump.

Update: A portal to all of TTAC’s related articles on Toyota gas pedals is here:

Toyota has released their official “fix” for the sticky CTS-made gas pedals on the recalled models affected. From their graphic, it’s difficult to understand what parts are involved, and how they work. Thanks to our recent tear-down of the CTS pedal, we have the pictures and familiarity with the unit to explain it in detail. (Read More…)
