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.

As the earlier post indicated, the Germans are increasing exports while their domestic market swoons. The German Big Four all posted increases in February, as well as YTD. Daimler experienced the least levity, with the Mercedes brand up 5% while Smart continues to smart, down 69%, and 77% YTD. The only bright spot: Smart was at least up substantially in February over last month, but when the total units is 442 for the month, its just not much to crow about. The new E-Class was up a hefty 92%, and the C-Class continues as the biggest volume seller and was up 6%. Mercedes is up a decent 20% YTD.

BMW had a cheerier month, up 14% overall. The BMW brand was up 26%; the Mini only 2%, continuing its laggard ways of late. The X5 shot up 76%, and the new 7 Series is the top dog in its category YTD. Audi and VW follow, but not in sales increases; (Read More…)

Always hankered for a Citroen? The Subaru SVX is the closest thing we’ve gotten to one these past few decades. I find the resemblance to the XM more than coincidental. Which is a bit odd (or not) considering that the XM beat the SVX to the market by a few years (1989). And the XM was styled by Bertone, while arch-rival Giorgetto Giugiaro’s Ital design did the SVX. A case of great minds thinking alike? Or just the styling cliches de jour? Given the Subaru’s “aircraft-inspired glass-to-glass canopy” with the very unusual windows within windows, the SVX was actually more “Citroen” then the real thing. No wonder it’s such a curious oddity today. (Read More…)

The Honda Accord has Camry schadenfreude written all over it. With a 41% increase, and 22k units sold, the Accord is off to a likely win in the passenger car sweepstakes of 2010. The Civic didn’t ride the updraft nearly as well, with a modest 5% lift. The Insight’s 2k units continue to tail the Prius’ 8k units by a 1 to 4 ratio, somewhat better than a few months back.

The Honda brand was up 12%, and Acura by 17%. But all of Acura’s cars were down; its growth was fueled by the two CUVs: MDX: +65%; RDX: +20%. Honda CUVs were all down a bit, and the Odyssey up a tad. And three FCX Clarities were leased. Full details: (Read More…)

Is it good news or bad news? After January’s 16% drop, February’s 9% slide could be evidence that the worst is behind Toyota’s fall from sales grace. It certainly seems that the models most connected to the recalls and bad news are being hit the hardest, with the flagship Camry down a nasty 20%. Just to show how the tide has changed, Camry outsold the Fusion by exactly 93 units. The Avalon was off 65%, suggesting that the gray panthers are avoiding its UA issues; let’s just hope they’re not buying Town Cars instead. The newly revised Lexus ES 350, also a UA posterchild, was off a fairly mild 9%.

Overall, Toyota brand vehicles were hit harder (-11%) than Lexus, which was up 5% in the month. The Lexus GX (+185%) helped keep the division in the positive side of the ledger. Prius managed a tidy 10% gain despite the bad publicity. Corolla was down a modest 6%. The new 4Runner is off to a good start with almost 3k units and up 55%. Full details after the jump: (Read More…)

Here’s a question for you automotive sales historians: when was the last time (month) Ford outsold GM? Four hundred and seventy one cars was the difference, but the bragging rights would have been worth it if Ford had given them away. Here are the highlights: Sales were up a Toyota tidy 22% from January. Camry-fighter Fusion experienced unintended sales acceleration, rocketing ahead at an unrestrained 116 mph percent.Ford brand vehicles were up 46%; Mercury +24%; Lincoln +19%.  Company wide, passenger cars were up 54%, utilities +39%, trucks +36%. Retail sales were up 28%, as fleet sales came back to “normal” after a near stand-still a year ago. Ford estimates its February market share at 17%, up a hefty 3 points from a year ago. Detailed charts follow: (Read More…)

The Wankel rotary engine returns to its native land at last. Since the NSU Ro 80 went out of production in 1977, Mazda has been the keeper of the flame. But Audi has announced that it will show an A1 e-tron concept at the Geneva show this week, and the pug-in will feature a single-rotor Wankel range extender (gen set). Rotaries and micro-turbines have often been suggested as the ultimate range extenders due to their compact size and low weight. (Read More…)

It’s morning on a bright summer day in Iowa City in 1962. I may have fallen asleep with pictures of Marilyn and the Corvette, but now they’re lost somewhere in the folds of my sheets. The fantasy is over, and its time to face a reality of rampant Rambler Classic wagons with wheezing sixes piloted by boozy but anything but sexy Moms. Instead of a fancy night club where a jazz band is playing, we’re off to the pool, and if we’re lucky a stop at the Purple Cow drive-in for milkshakes and floats afterward. The distinctive pattern of Rambler upholstery seared into the backs of my thighs and the stain of artificial strawberry on my trunks will be the tell-tale of having crowded in with half a dozen other hot (the wrong kind) and sticky kids in the back seat. Why did I have to find you, Rambler Classic Wagon? I was so enjoying my fantasy memories. (Read More…)

Edmund’s has been leading the NHTSA data dives to shed light on the UA issue. I used their numbers of NHTSA complaints in our attempt to correlate the complaints to specific cars and their sales in the ’05-’10 period to determine the rate of UA complaints. Now there’s a major new wrinkle that throws that effort into question: Over half of UA complaints against Toyota since 2005 were filed after Toyota issued their On Sept. 29, 2009 consumer safety advisory regarding floormats that could trap the accelerator pedal and cause unintended acceleration. That still leaves Toyota with the highest rate (4.81 per 100k cars sold)  number of complaints for UA events before that date, but only marginally ahead of Ford (3.12). That means our stab at individual car model rates is flawed, and we’ll try a Take 2 when we have more accurate sales and adjusted NHTSA complaint numbers before that cutoff date. It’s obvious that incorporating the flood of complaints against Toyota since the mat issue hit the media would just be feeding the frenzy. (Read More…)

The gen 1 Infiniti Q45 (G50) deserves a full-on CC. But when I stumbled unto these two together in CA over the holidays, I realized how incredibly rare the gen2 Q45 (FY33) is. I don’t think I’ve ever seen one in Eugene. Well, it was a sales bomb, and from an enthusiast’s point of view, a well deserved one. The original Q45 (’90-’96) was such a remarkable beast, one of the best things to ever come along in its era. It had a killer motor, rated conservatively at 278 hp, which put the big German sedans to shame at the time. It had a fast steering ratio, and its suspension tuning was all about the right stuff. But except for the (limited) enthusiast crowd, it never broke through in sales like it Lexus LS 400 competitor. And then it went downhill. (Read More…)

Call it the ultimate of ironies. Yesterday afternoon I headed to the Toyota dealer in my 2005 Toyota Scion xB for the purpose of shooting photographs of various Toyota gas pedals to see why certain models seemed to have a higher rate of UA complaints to the NHTSA. In search of some intended acceleration, I headed up the up-hill I-105 connector on-ramp at Washington Street at full throttle. As I lifted my foot off the accelerator pedal, it stayed wide open… (Read More…)

[Eugene culture alert] It’s sunny and warm outside (and Saturday) , so I’m going to have to skip a long-winded essay on the joys and artistry of this beautiful 1970 Montego. Instead, you can just enjoy this color-coordinated Montego montage, and hopefully fill in some of the blanks. Let’s just say its not every day one finds one of these, especially in the front yard of an artist’s house. It’s his contribution to the colorful streetscape of Eugene, and now you can enjoy it too. I sure did. perhaps I should start a monthly Eugene art-car walk. (Read More…)

The Obama Administration warns that automakers could be hit with unintended acceleration of  their costs if Congress succeeds in blocking EPA greenhouse gas emissions. The Detroit News reports:

In a letter to congressional leaders, the National Highway Traffic Safety Administration’s chief counsel, O. Kevin Vincent, said Congress would jeopardize a deal reached by automakers, California and the White House if it blocks the EPA from using its power to limit greenhouse gases.

California and a dozen states could go forward, each with its own rules, if Congress blocks EPA from setting national standards. That would have the impact of “creating confusion, encouraging renewed litigation, and driving up the cost of compliance to automobile manufacturers and consumers alike,” Vincent wrote.

A number of articles have appeared implicating tin whiskers as a potential source or complicating factor in Toyota’s (and other manufacturers’) unintended acceleration issues. The phenomenon of tin whiskers, a crystalline metallurgical phenomenon involving the spontaneous growth of tiny, filiform hairs from a metallic surface, can cause short circuits and arcing in electric equipment. First discovered in phone switching equipment in the 1940’s, the addition of lead to tin solder largely eliminated the problem. But the push to eliminate lead from electronic assemblies has led to a nasty re-growth of the pesky whiskers. And some are pointing fingers. (Read More…)

[Update 3: This post is now officially obsolete, having been supplanted by the much more accurate update here]

[Update 2: In a new post, I have noted that 53% of Toyota UA complaints were filed after the mat advisory was issued on 9/29/09. The number used her are not adjusted for that. As soon as they are available, I will redo this spreadsheet, using more accurate sales stats]

[Update ans Disclaimer: As I noted below, this spreadsheet will be updated when I can access actual sales stats from our source, Morgan and Co. on Monday for the years (’05-’10) covered. That will very likely change the rankings somewhat. The Lincoln may actually be #2. But this is not about which car is #1 or #2; it’s about finding patterns in certain makes, and within makes. It’s an attempt to see if these statistics can shed light on a complex and opaque issue. As an example, why the Toyota Yaris is so low in reported incidents. It’s more about these patterns and discrepancies, than about singling out the car with the highest rate, so please don’t take the current exact rankings as the final word. It’s a work in progress. The fact that the complaints are not tabulated by individual MY also limits this substantially, as running changes in a given car during the five year period will change things significantly. So this data dive is fundamentally flawed; take it as such. But nevertheless, it’s still a huge step over the raw data that Edmunds put out, which doesn’t begin to account for the number of any given cars sold.]

Numbers and statistics are largely useless without context. Edmunds.com took a first good step in going through NHTSA’s data base and reporting the number of UA events reported per make, brand and vehicle. But what was obviously missing was the correlation to the number of cars on the road in relation to those numbers. We’ve taken the next (tedious) step, and the results are most interesting indeed. They’re certainly not completely conclusive, but we’re not finished yet. The full list of 95 cars follows, as well as our methodology, a stab at some analysis, and more questions to still be answered. (Read More…)
