Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I am reporting the issue of coolant line fitting failure. I have not had a failure yet but that my mechanic has advised me that this issue must be addressed and repaired before there is a catastrophic failure. This is a known and expensive issue so rather than waiting for a failure, I was advised by a mechanic that it is going to fail and needs to be repaired immediately.”
NHTSA complaint #10515392, filed 2013-06, 40,000 miles“Coolant leak noticed at coolant manifold fitting during oil change. Engine was warmed up prior to oil drain, therefore was at operating temperature. Seepage at fitting into manifold was detected by smell and then located with light and mirror. I had to have the engine removed and the fittings welded by my local independent shop. All of the fittings were glued into the castings and were prone to failure at any time.”
NHTSA complaint #10510000, filed 2013-04, 14,370 miles“I was driving my car on I-79(3 lane highway) at 70 MPH when I noticed a large cloud of smoke/steam from the rear of my car. I then noticed other cars pulling off to the side to get away from all the coolant spraying from my car. I pulled off to the side of the road and called for a tow truck. Ounce I was able to get Porsche dealer to look at the issue, it was indicated that my coolant fittings failed and separated from the engine(know issue).”
NHTSA complaint #10525242, filed 2013-07, 4,960 miles“Sudden coolant line fitting failure. The epoxy failed and a coolant fitting completely popped out of the engine housing near the alternator. Resulted in rapid coolant loss. Car had to be towed/hauled approx 140 miles to repair facility near my home. I have not yet seen the bill for this service. I am having all coolant fittings welded to prevent this from happening to any of the other lines. Work is not yet complete but the estimated bill is $3500+.”
NHTSA complaint #10534755, filed 2013-08, 23,192 miles“No incident occurred. However, based on my knowledge of the failure of the coolant fittings in my car and wanting to take a proactive stance I elected to move forward with a remedy. While at the dealership on another matter, the engine had been removed allowing limited access to a number of the coolant fittings. Since the dealer disavowed any knowledge of the problem and was therefore unwilling to help I took it upon myself to mechanically fasten those coolant fittings which I had access to. Mind you all while the dealer looked on. …”
