Suspension coil springs break at very low mileages (around 40k or 50k mileages) impairing ride, steering and braking making the vehicle unsafe to drive. Besides the suspension coil springs corroding, there seems to a larger problem of the entire underbody corroding with the toyota siennas.

Since driving my 2008 seinna limited over 61,000 miles, I have been noticing metal-rattling noises. I brought it to a mechanic, and they found the front, driver side suspension coil spring was fractured. I was told by the mechanic that it's not common, and I checked any recalls on it from toyata and the federal safety agency websites. There are no open recalls, but on the internet I saw the same problem happened to 2008 sienna in several cases.

2004 sienna le: failure of driver side front suspension spring in january 2012, passenger side in january 2013. Each spring cracked causing vehicle to drop while in motion. Metal in cracked areas appeared porous possibly suggesting flaws in metal during manufacture. 2013 failure included crack near middle of spring, with a sharp broken piece sticking out close to tire. Thankfully occurred while parking/at low speed; failure at high speed may have resulted in puncture of tire/loss of vehicle control. 2012 failure included crack near top. Photographs of the 2012 spring are available upon request. Vehicle is in good condition, with only ~65,000 mi at time of first incident. Driven on paved roads, light loads. Body rust free with minimal surface corrosion of unpainted/undercarriage items. Contacted toyota in 2012, filed case. Was informed similar issues had not been reported, failure was not covered. Noting extreme hazard posed by broken spring puncturing tire, encouraged further evaluation. Obtained/replaced at my cost spring from local toyota dealer, had aligned. Contacted toyota in 2013 regarding second failure. Noted was second occurrence/extreme hazard posed by puncturing tire, encouraged further evaluation. Obtained replacement/had aligned at my cost. Recently contacted toyota; no new information available. Broken springs can result in loss of vehicle control as can tire puncture. Failures I experienced occurred at low speeds; if at higher speeds, results may have been catastrophic. Noting light use and excellent condition of vehicle as well as appearance of the broken springs, toyota parts staff and outside mechanics indicated that manufacturing issues may be cause of failures. Replacement springs included different color coding; parts staff indicated this may correspond to more recent production, suggested that new parts may be of better quality.

Our sienna is a well maintained, low mileage (just over 66,000 miles) vehicle. As of august 30 of this year, the transmission planetary gears have totally failed, leaving the vehicle and us stranded over 100 miles from home. The estimate for a complete transmission rebuild from a reputable transmission specialty shop is $4500, which is much lower than the estimate of $6500 that our toyota dealer gave us to install a remanufactured transmission. Based on the number of complaints I have read about on the internet, this particular transmission seems to have had significant problems with early failures around the 65,000 mile mark. This repair is on top of a $1000 repair just a month ago to replace both of the rear coil springs. Both springs failed at the same time, with the bottom coil rusting through and failing at the bottom spring support. As a materials engineer myself, I believe this is a design or production issue with these springs, for both to fail in the exact same spot on the same coil at the exact same time. (and it is worth pointing out that this vehicle has spent its life in northern virginia, a place that does not have much snow, or extensive use of road salt.) also, just about a year ago, we had to have the steering rack replaced at the dealer's recommendation, which was another $1000 repair. So in a period of just over a month, this vehicle is going to have almost $6000 of repairs to it (not including the steering rack repair.) this is completely unacceptable for a low mileage vehicle, especially for a toyota, which are normally highly reliable. This vehicle has been maintained by a reputable local toyota dealer, so all of the records are available to you.

My local garage discovered that a suspension coil spring in my 2010 sienna is broken. I have discovered by searching the internet that this is fairly common in toyota sienna models (I saw 2007, 2008 and 2009 models reported to have this problem, in my very brief internet search). This is a family car, and has seen only normal highway driving, no heavy loads and certainly nothing that would normally break a spring. I have discussed this with both the local toyota dealership's service manager, as well as the corporate toyota "customer experience" representative. I have explained that a broken coil suspension spring could result in a slashed tire sidewall and associated blowout; a slashed brake hydraulic line and associated loss of braking ability; erratic suspension movement and associated loss of control of the vehicle at high speed. I have been told by toyota that there is no recall nor repair assistance for this problem.

Tl* the contact owns a 2007 toyota sienna. While traveling approximately 30 MPH, there was a loud noise and a component fractured without warning. The contact was able to merge to the side of the road and, after inspecting the vehicle, the contact noticed that the front passenger side coil spring fractured. The vehicle was taken to an independent mechanic who diagnosed that the coil springs needed to be replaced. The manufacturer was notified of the failure. The approximate failure mileage was 82,700.
