Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“My wife started the engine in a church parking lot and the battery literally exploded, spreading battery acid under the hood. Besides the battery, the only visible damage was a badly pitted fan. The battery was a replacement which had been installed by competition Infiniti, smithtown, ny, 2 years and approximately 20,000 miles earlier. After some discussion, the dealership finally agreed to pay for a replacement battery and fan. I was told that there was no further damage under the hood. An employee volunteered that this was the second exploding battery they had seen in the recent past. …”
