Example complaints

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

“My family and I were driving about 55mph and the glow plug warning light started flashing and the vehicle stalled after a mile or so. The dealer said that the fuel was contaminated and that the whole fuel system had to be replaced and was going to cost more than $11000. The service guy said the dealer was paying for it because they are good guys, boloni. We could have had an accident and died because it was at night on a 2 way road and barely no room on the side of the road. I say from everywhere I've read it is a faulty hpfp. Car only has 65000 miles too.”

NHTSA complaint #11299038, filed 2020-01, 64,500 miles

“In january 2019, while I was driving on ca 110 in excess of 60 MPH, the Audi Q7 tdi's glow plug indicator light came on, I lost acceleration and a few minutes later, my engine shut off and I was stuck in the left lane. I had to call 911 and have chp stop all traffic and push my car to the shoulder while I awaited a tow truck. Audi dtla told me that the high pressure fuel pump failed and that there was metal shrapnel in my fuel line and it all had to be replaced. They said this was a diesel warranty covered issue and we did not pay any charge. …”

NHTSA complaint #11232497, filed 2019-07, 44,782 miles

“I was driving on the highway at 55-75 miles per hour. I saw an orange indicator light for the 'glow plug system' appear, with no previous warning. I continued to drive for several minutes, but felt a loss of power. The accelerator when depressed did not respond with power. I was in the left lane of traffic which slowed down to a standstill, but when traffic picked up, my car stalled and stopped completely. I tried to restart the engine unsuccessfully. I was stuck in the left lane of traffic and blocking oncoming traffic at high speeds. It was very dangerous and I had two children in the car. …”

NHTSA complaint #11172569, filed 2019-01, 35,400 miles

“Car periodically stalls on accelerating from a stop, even though engine is up to normal operating temperature. Car will get to approx 10-15 MPH, then stall, with a complete loss of power. Must push gas pedal all the way to the floor to overcome the stall, then the car leaps forward, spinning the tires. This has happened several times in the past few weeks. Am very concerned whenever I start up at an intersection, as I don't know when this situation will occur. I think this is a safety issue which should be corrected.”

NHTSA complaint #10567601, filed 2014-03, 2,670 miles

“The glow plug light came on and off and the vehicle completely lose acceleration (no power) on the freeway during normal driving. This is the second time that this happens to me. The first time that it happened in june of 2020, the recall was done on by Audi dealer assuming that the problem would go away, but it came back.”
