I purchased a new vehicle from the dealer in 2014 in 2019 the wood grain trim cracked. I had this replaced by the dealer in 2019. Now again, in 2024, the same issue the wood grain has cracked. This should not be happening every few years.

Exterior Lighting
Filed Jan 12, 2023IN

The turn indicators stop working suddenly and randomly giving inaccurate/false indication to the driver of the vehicle that indicators are turned on and no indication of turn signal to the other drivers that can be hazardous especially at the 4 way stop signs where other drivers are assuming that vehicle is going straight where as the vehicle is intending to turn left but it is doing it without the indicator due to sudden failure of turn signal indicators and during lane changing. The hazard warning continues to work just fine and the turn indicator functions return to normal after turning the ignition off and back on. The occurrence of turn indicator failure is quiet often and has no set pattern.

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
